Provider-owned system +skills are reported separately. Every installed resource is checked against its +source digest after removing the local marketplace's carrier source. + +The Claude command uses the locally installed Claude executable, a private +temporary home, empty setting sources, `plugin validate`, and `plugin details` +with an inline plugin directory. It checks exact Lean/Full-with-exclusion skill +inventories and zero agent, hook, MCP, and LSP components. Reported token costs +are the provider's projections, not measured usage. Manifest attribution and +version warnings remain visible. + +The switch probe uses the product's managed store and isolated native adapter for +Full, Lean, and rollback to Full. Preparation creates a separate provider home +and registers the selected carrier, then opens a fresh app-server to verify +discovery. Rollback first restores managed authority, then re-verifies the prior +native home and selects it. The Full Python exclusion and unrelated bytes in the +prior home must survive every transition. Each native pointer binds its managed +store revision, carrier digest, exact provider version, and native executable +SHA-256. Read-only status rechecks receipts, native configuration, cached resource +bytes, and the pinned executable. Existing sessions and host registration remain +unchanged. + +The Podman runner runs the normal `npm pack` lifecycle, reports its archive +SHA-256, and builds an isolated consumer from that archive. It installs runtime +dependencies and pinned Codex 0.154.0 during the image build. The final container +runs as the image's unprivileged `node` user, with networking disabled, all Linux +capabilities dropped, no added host mounts, and no copied credentials. It checks +all ten target/profile combinations through the packed public CLI and independent +structural oracle, including exact carrier equality with the source checkout. +It also checks the packed CLI's Full/Lean/rollback lifecycle, idempotency, stale +revision rejection, Auto context loading, Suggest/Manual/dry-run boundaries, +pinned receipt reuse, and no-workflow reset. It then repeats native Codex discovery +and product native preparation/rollback. The packed CLI also prepares a native +generation and verifies an isolated launch dry-run with no provider on PATH. +Test helpers are +copied separately into the image; they are not part of the published package. + +An existing compatible Node image can be selected with +`ECC_CONTEXT_NODE_IMAGE=`. The default is `node:22-bookworm-slim`. +The task image and private temporary build directory are removed afterward. +Dependency download layers can remain in Podman's ordinary build cache. The +runner never changes host harness configuration or mounts a host home. + +The outcome evaluator (`ai-eval.js`) measures graded task success and provider +usage across install arms; see `ai-corpus.json` for the 30-task repair corpus +and `complex-eval/DESIGN.md` for the preregistered three-task complex-task +benchmark (feature build, incident triage, security hardening) with scored +hidden graders, reference solutions, and reproduction instructions. + +These checks certify the observed discovery paths for the reported exact provider +versions.

Queries are written as a real user would phrase them, with no ECC +vocabulary, no hints about which skill applies, and no instruction to use any +particular methodology. Each task has one clear correct outcome and a +deterministic, dependency-free grader. + +1. **`webhook-relay`** (feature build). Finish an asynchronous webhook delivery + worker: retries with exponential backoff, dead-lettering after 5 attempts, + status reporting, under load. Graded by 9 in-process behavioral probes + (delivery after failures, exact attempt counts, backoff timing window, + dead-lettering, error capture, API preservation, concurrency). + *Why it belongs here:* everyday backend feature work where test discipline + and backend patterns genuinely change outcomes; canonical skill: + `tdd-workflow` (a second skill would exceed the 32 KB selection budget — + itself a measured constraint of the scoping layer). + +2. **`incident-triage`** (debugging / root cause). Finance reports one-cent + total errors since yesterday's deploy. The repo contains three changelog + entries (two red herrings), an incident log with concrete amounts, and a + regression: a "readability" refactor that switched integer-cent math to + decimal-factor floats, which under-rounds exact half-cent boundaries. + Graded by 5 boundary-value totals the float path provably gets wrong, one + regression probe, and 2 deterministic checks on the required `INCIDENT.md` + (names the right changelog entry, explains the rounding mechanism). + *Why it belongs here:* evidence-driven diagnosis under uncertainty is the + highest-leverage agent workflow; guessing is penalized because red herrings + are plausible; canonical skill: `orch-fix-defect`. + +3. **`sentinel-api`** (security review + hardening). A paste service whose + README documents the secure contract while the code violates it five ways: + hardcoded admin token, path traversal, reflected XSS, predictable delete + tokens, no body-size limit. Graded by 10 exploit probes (each vulnerability + must actually be closed) plus functional regression probes (the documented + API must still work), including one encoded-traversal variant so partial + fixes score partially. + *Why it belongs here:* security review is a canonical agent task with + objectively checkable outcomes; canonical skill: `security-review`. + +### Why these tests are effective + +- **Realism over benchmark gaming.** Each task is a small production-shaped + repo with docs, tests, logs, and changelogs — the inputs a real engineer (or + a real user of an agent harness) actually has. Nothing references ECC. +- **Correctness is decidable.** Every grader assertion is deterministic: + behavioral probes against the agent's own running service, exact numeric + answers on boundary cases, static source checks, exploit probes. No LLM + judges, no rubrics, no human scoring. +- **Partial credit.** Graders emit `ECC_EVAL_SCORE {"score": 0..1}`, so "found + 4 of 5 vulnerabilities" registers as 0.9-of-task progress instead of a binary + failure. Pass/fail (score = 1.0) is reported alongside the mean score. +- **Hard to luck into.** Red herrings (incident-triage), timing windows + (webhook-relay), and exploit-verified fixes (sentinel-api) mean superficial + plausible work scores low. +- **Fair across arms.** Hidden graders run only after the agent exits, from a + read-only sandbox; the agent never sees the grader. The same grader scores + every arm identically. Reference solutions score 1.0 and as-shipped fixtures + score ≤ 0.3 (`verify-checks.js` proves both before any provider call). + +## Measured variables + +Per trial (one task × arm × repeat), from the provider's own usage events: + +- **Fresh input tokens** (input + cache-creation), **cache-read tokens**, + **output tokens** — the context-cost story. +- **Provider calls** per trial (1, or 2 when auto-lean needs a routing proposal). +- **Wall-clock time** per provider call and per trial (ms) — time to completion. +- **Score** (0..1) and **pass** (score = 1.0) from the hidden grader. +- **API-equivalent cost**, derived at analysis time at Anthropic Opus list + prices ($15 / $1.50 / $75 per million fresh-input / cache-read / output + tokens). This is an accounting convention for comparison, not a billing + claim; subscription pricing differs. +- **Skill routing** (auto-lean): which skills the trigger/proposal machinery + selected vs the maintainer-chosen canonical set, reported as the selection + probe accuracy — the direct measure of "automatic skill matching". + +Comparisons are **within-run only**: same provider, model, executable digest, +corpus digest, and source digest, paired by task and repeat. Cross-run and +cross-provider comparisons are invalid by design. This is a descriptive pilot +(3 tasks × 5 arms × 4 repeats = 60 trials): it estimates direction and +magnitude, not population statistics, and the report says so in its gate block. + +## Reproducing or auditing + +Everything below is committed; there are no hidden inputs. + +```bash +# 1.

Use +`--allow-credentialed-tools` only with a trusted local corpus and credential. Without that +explicit flag, real Claude task evaluation stops before a provider call; selection-only calls +remain tool-free. This development evaluator does not provide a credential isolation boundary. + +The registration digest binds the exact corpus, evaluator source, model, and +executable; the run refuses to start if any of them drift, and aborts if the +tree changes mid-run. `--artifact-dir` retains per-trial session transcripts +for independent inspection (they never enter the report). The `ecc-legacy` arm +is pinned by commit in `legacy-source.json` and exported from git objects at +run time. The Codex provider is unsupported for this corpus (the legacy arm has +no Codex install path); `--provider claude` is required. + +## Known limits + +- Three tasks is a probe, not a census: treat intervals as descriptive. +- Tasks are Node.js/stdlib by construction (graders must be hermetic); results + say nothing about other ecosystems directly. +- `webhook-relay` uses wall-clock backoff windows; bounds are wide (250–5000ms) + but loaded machines could in principle flake a timing probe. The grader + reports each probe individually so flakes are visible. +- Provider behavior varies week to week; the pinned model/executable digests + make a rerun comparable only within the same pin. +- Fixture wart observed in the 2026-09-25 run: on Node 24, `node --test test/` + no longer scans the directory the way Node 22 did, so `npm test` fails as + shipped. This is identical for every arm (the task says to make `npm test` + pass, and agents fix the script), so fairness holds, but it adds unplanned + work per trial. A future corpus revision should ship a portable test script. + +## complex-tasks@2 (discriminative revision) + +The @1 run saturated: every arm scored 1.000 on every task, so only economics +and routing differed. @2 (`cases2/`, built to `complex-corpus-v2.json`) is +designed to discriminate on the axes users actually pay for — correctness on +traps, solution efficiency, spec thoroughness — with wide partial-credit +spreads. The @1 corpus and its report stay untouched for comparability. + +1. **`keccak-selector`** (domain-knowledge trap). Implement Ethereum function + selectors from scratch, stdlib only. The trap: Node's crypto offers + SHA3-256, which shares the Keccak-f[1600] permutation but differs in + padding — the naive one-liner is wrong for every vector (verified: the + naive control scores 0.25, format checks only). Graded by 9 selector + vectors including a padding edge case, all cross-validated against Node's + SHA3-256 on shared-permutation inputs. Canonical skill: `nodejs-keccak256`. + *Hypothesis:* the skill body carries exactly this knowledge; bare agents + must rediscover it. + +2. **`event-stats-api`** (correctness edges + measured efficiency). A shipped + implementation that is both wrong on the documented edge semantics + (interpolated instead of nearest-rank percentiles, zeros instead of nulls, + unrounded averages, missing 400s) and algorithmically naive (full-log scan + and sort per query). Graded by 10 independently computed correctness probes + plus a measured 2,000-query performance budget (threshold 6s; shipped naive + ~7.7s, reference ~1.5s — calibrated on the grading machine in + `calibrate-stats.js`). Canonical skill: `backend-patterns`. *Hypothesis:* + solution *efficiency* separates arms even when correctness doesn't. + +3. **`forge-cli`** (spec thoroughness + robustness). Twelve contractual + behaviors with exact messages, exit codes, sorting, and a never-throw + guarantee, graded by 26 checks including junk-input fuzzing and static + hygiene (no leftover TODO/FIXME, no new dependencies). Canonical skill: + `tdd-workflow`. *Hypothesis:* checklist discipline shows up as breadth of + completion, and partial credit spreads the distribution. + +First @2 run uses `claude-opus-4-8` (cost discipline); the corpus is +provider- and model-pinned per run, so a later Opus 5.5 rerun on the same +digest measures the model difference directly. repeats=2 (30 trials): simple +experimentation, expand later. + +## complex-tasks@3 (vagueness and horizon; arms: auto-lean vs baseline) + +@2 still saturated on outcomes (30/30) — enumerated specs are within the +model's cold competence. @3 (`cases3/`, built to `complex-corpus-v3.json`) +moves grading to what users actually complain about (see the complaint +taxonomy in this file's discussion: happy-path-only work, unverified +completion, skipped implied work, convention drift, concurrency blindness). +Everything graded is discoverable from repo docs visible to every arm — the +question is whether agents reliably *do* all of it under vague instruction. + +1. **`chained-tickets`** (long horizon). Four sequential tickets in one + accumulating workspace — build a link shortener core, then vague tickets: + "links need to survive a restart", "we're seeing abuse, deal with it", + "track redirect hits, consistent with the existing API". 33 hidden probes + across the four steps grade function, convention compliance (error + envelope, layering — pinned in a visible CONTRIBUTING.md), and implied + work (changelog entries, growing tests, accurate README). Stepped trials + grade each ticket after its call; a failed ticket ends the chain. +2. **`production-ready`** (vague prompt, heavy implication). "This goes to + production Monday — get it ready." A documented production bar + (validation envelopes, body limits, /health, structured request logs, env + config, graceful SIGTERM, nosniff, error-path tests, changelog) graded by + 16 probes against a naive prototype. Fixture scores 0.063. +3. **`idempotent-webhooks`** (the "almost right" trap). A payment receiver + whose shipped code has a textbook check-then-act race (INC-104). Hidden + grader fires 50 concurrent identical deliveries plus replay, already-paid, + mixed-storm, and contract probes. The naive fixture double-applies and + crashes on unknown orders (0.25). Exactly-once requires claiming events + synchronously — the discipline skills like `error-handling` encode. + +Grader robustness (hard-won, now fixed and unit-tested): a graded server runs +in-process, so a crashing server kills the grader. Graders install +uncaughtException/unhandledRejection handlers, emit their score line via +`process.stdout.write` (immune to the log-capture patching used in probes), +pre-declare their check totals (unreached checks score zero), and the +evaluator itself treats a score-advertising grader that printed nothing as a +zero (`graderDied` guard in `runScoredCheck`). Stepped graders may write to +the workspace (persistence probes); single-step graders stay read-only. + +First @3 run: arms `auto-lean` and `baseline` only, repeats=1, +`claude-opus-4-8` — the direct test of "ECC auto-routing vs no harness" on +quality, time, and tokens. Full-arm and Opus 5.5 replications follow if the +spread shows up. + +## complex-tasks@4 (learning loops; adds recurring-incident) + +@4 (`cases4/`, built to `complex-corpus-v4.json`) keeps the three @3 cases +unchanged and adds a fourth targeting a different ECC value prop: converting +a fix into durable, reusable prevention — and *reusing your own artifacts* +later in the session. Baseline agents can hold this in context; ECC's claim +is that skills/workflows make it systematic. + +4. **`recurring-incident`** (learning loop / institutional memory). Three + chained steps against a dependency-free payments service whose gateway + records side effects in an append-only JSONL ledger. Step 1: keyless + refund retries double-refund (INC-201/214/227 "third time this quarter" + trail in `docs/incidents.md`); the vague ask is "make sure this stops + being a recurring incident." Probes: functional correctness across a + module reload (kills in-memory-only fixes) [0.40], regression test wired + into the suite + mutation probe [0.30], a durable prevention runbook + [0.20], and the mechanism living in one shared helper module [0.10]. + Step 2: payout retries, "same family of problem" — graded on REUSE of + the step-1 helper (static import check + no divergent inline + reimplementation) [0.30] alongside function [0.40], test+mutation [0.20], + doc update [0.10].

Canonical IDs remain stable; destination directories use validated native metadata names, which can differ from canonical directory IDs. Full honors explicit exclusions. Routed and excluded skills contribute no carrier files; routed retrieval remains future work rather than an extra undisclosed bootstrap skill. Generated manifests use a narrow field allowlist and never inherit ECC's monolithic hooks, MCP configuration, agents, commands, or broad instruction lists. + +Copy operations retain binary byte digests and sizes rather than embedding decoded bodies. Generated manifests bind exact UTF-8 bytes. Required resources must exist in the selected inventory. Duplicate native names, case-colliding paths, unsafe paths, nested case-insensitive skill entrypoints, or source-plan drift fail before a carrier can be returned. + +Preserved skill files can contain their own authority-related metadata, including `allowed-tools`.

It does not accept a user destination. Tests cover resource omission, extra or changed bytes, binary preservation, source drift, symlink substitution, failed-write cleanup, and unrelated sentinel preservation. Generated content must match its independently compiled expectation; a carrier's self-reported digest cannot redefine acceptance. + +Structural evidence and native evidence are distinct: + +| Claim | Required evidence | +| --- | --- | +| Materialized file set and byte integrity | Fixture comparison against independent expected source and generated content | +| Bundled resource completeness and relocation | All selected resources present; verification still works after source removal | +| Native visible IDs and exclusions | Future fresh-session probe for a named provider version and install path | +| Skill loading and useful workflow execution | Future native invocation and task-outcome checks | +| Activation, reload, rollback, hooks, whole-context cost | Later dedicated lifecycle, consent, and measurement gates | + +No structural result may set native discovery, invocation, activation, or token usage to verified.

Ownership receipts and staging/rollback mechanics remain queued for P3. Its extra catalog bootstrap and copying of all unselected skills are not carried forward because they would change the approved selection or leak exclusions. + +LovePlayCode's [#2844](https://github.com/affaan-m/ECC/pull/2844) grouping and deterministic selection ideas inform the shared inventory. Its broad Full directory projection cannot preserve explicit exclusions, so the carrier uses the canonical selected IDs instead. These source contributions remain independently reviewable with attribution; this work does not merge or close their PRs. + +Codex and Pi layout fields are grounded in ECC's existing native manifests; provider mirrors are not used as canonical resources. Claude's [documented path rules](https://code.claude.com/docs/en/plugins-reference#path-behavior-rules) require install-path-specific exclusion tests because default discovery can be additive. OpenCode's [skill-name rules](https://opencode.ai/docs/skills/#validate-names) require the native directory name to match metadata. These constraints inform projection fixtures and do not substitute for fresh-session observations. + +## Next gate + +Earn native discovery and exclusion evidence using isolated homes and exact provider versions.

Runtime coverage excludes test infrastructure. + +## Real inventory and package verification + +All ten source-tree Lean/Full combinations across Claude, Codex, Pi, OpenCode and Cursor passed disposable structural verification against the actual canonical inventory. Full contains 286 skills and 464 bundled files. Claude, Codex and Pi add one narrow manifest, giving 465 files; OpenCode and Cursor retain 464. Lean contains 3 skills and 3 source files, plus a manifest where applicable. + +At implementation head `d52d3430`, the full `npm test` exited 0 and its legacy aggregate reported 4,423 passed and zero failed. That aggregate does not separately count the new node:test cases, which are reported explicitly above. Full ESLint/Markdown lint and whitespace checks passed before this source-only evidence update. + +A real `npm pack` ran the normal prepack build. The archive SHA-256 was `dd0577889bfa09071cbd87b430b200f8d0eaf036c6b0fb583dc71ae2f855fd78`. A disposable consumer installed it with `npm install --offline --ignore-scripts --omit=dev --no-audit --no-fund --userconfig=/dev/null`, using a task-local cache explicitly primed online during the preceding PR-readiness check. This proves an offline cached install, not a dependency-free install. + +The installed public dispatcher produced all ten Lean/Full carrier objects with deep equality to the checkout, including their complete digests. Each installed artifact then passed structural materialization using the installed package's own canonical skill resources and an independently compiled expected plan. Full's 464 bundled resources were verified in every layout. The isolated subprocess environment was allowlisted and its disposable home remained absent. Packed runtime resolution confirmed js-yaml 4.3.2. + +A separate policy simulation denying Windows file symlinks passed all 54 new resource/carrier/fixture cases with zero skips. Directory links use junctions on Windows. This simulation supplies no native Windows filesystem or provider evidence. + +Hosted review of the prerequisite PR subsequently identified dry-run argument ordering and directory-enumeration bounds. Fixes and their dependent-stack revalidation follow; the `d52d3430` results remain a pinned earlier checkpoint. + +## September 9 review hardening and final verification + +The stack inherits the prerequisite PR's global dry-run fix `9b5e3934` and bounded-reader fix `5f9503e6`. Their RED checkpoints are `c373b7fe` (27 CLI passes, 4 failures) and `ea00894d` (7 support-test failures). The reader keeps all file-byte and identity protections and now limits incremental directory enumeration. Public context-profile documentation describes the exact limits. Source-reader extraction received independent security review; its largest function is 20 lines. + +Carrier checkpoint `ebd43bef` independently reproduced the global flag failure: 6 CLI cases passed and 1 failed. Merging the prerequisite fixes in `072a3160` makes all 7 carrier CLI cases pass, including a leading global flag and a flag between an option and its value. + +The first merged focused run passed 98 outer tests and failed 2 alias regressions because their old `readdirSync` mocks no longer supplied synthetic alias names to the incremental reader. Test-only correction `46924366` models those same source directories through `opendirSync` instead. Both case/NFC spellings and the mandatory zero-staging-write assertions remain unchanged; independent review reran all 19 fixture cases successfully. No runtime change was needed. + +Final focused execution uses the coverage command above plus `tests/lib/context-profile-support.test.js`. It passes 132 logical cases, zero failures or skips: 18 registry, 7 support, 12 compiler, 13 resource, 22 carrier, 19 fixture, 31 original CLI, 7 carrier CLI and 3 CI. Outer TAP reports 100 passes. Runtime coverage is 98.37% statements/lines, 91.43% branches and 100% functions, with every threshold passing. + +Both prerequisite and carrier full-suite commands exited 0 with legacy aggregates of 4,429 passed and zero failed. The carrier run began at `072a3160`; its test-only mock correction was applied before the runner reached that fixture file, whose final 19/19 result was observed in the complete run. Runtime and packed files remained unchanged throughout. The final focused run independently exercised the corrected tests. Later changes update source-only evidence. + +The rebuilt carrier archive at runtime revision `072a3160` has SHA-256 `45ef651dfab1a9da9af7b7b4b4546c84bc6b325a31a95dac47d52def060649e6`. Its offline cached install and all ten installed-provider-layout Lean/Full parity and structural checks passed again. The archive has 2,628 entries; none of these checks launches a provider. A Git diff verifies final runtime, schemas, manifests, package declarations, lockfiles and packed contracts are byte-identical to that revision. + +The prerequisite runtime at `e54fd44c` separately passes 71 focused cases, 98.49% statements/lines, 90.46% branches and 100% functions, plus the full 4,429 aggregate. Its rebuilt offline-consumer archive has SHA-256 `e96826df9b336e180408c7765dcd4e09fca2fb7eb7252cbf84f2ff99d036b1a7`. Later prerequisite commit `be393cb0` only reconciles the source-only dependency evidence. Hosted CI is still pending for the latest PR revision. + +Lower-priority review suggestions remain explicit follow-ups: failing projection labels, one exported supported-profile list, richer budget-failure inspection and preserving dual CLI/snapshot diagnostics. Process-lifetime compiler caching is deferred until an immutable snapshot and invalidation contract exists. The current schema fixes the budget at 8,000; alternate ceilings are rejected. Private fixtures currently have only synchronous callers, and noncanonical skill-root directories remain rejected under the existing inventory policy. + +## Claims deliberately left unobserved + +Native discovery, exact native exclusions, invocation, executable-mode needs, workflow outcomes, activation, hook consent, rollback, automatic routing and actual token savings still require their own gates. Schema validation checks shape; it cannot certify supplied artifact semantics. The independently compiled fixture checks exact layout, selection, file set and bytes. It uses a trusted private temporary parent and does not certify an arbitrary-destination transaction writer against hostile concurrent mutation.

Ambiguous free text shortlists up to five candidates for a bounded proposal. Manual uses explicit IDs; suggest emits a proposal without bodies. `--load` returns selected UTF-8 instructions and declared required resources, capped at 32,000 bytes across at most eight skills. `--task-input -` accepts one UTF-8 JSON object on standard input, capped at 65,536 bytes. These byte caps are output and transport bounds, not native tokenizer results. + +Save the returned `selection.receipt` as a separate JSON document to use `--previous receipt.json`. `--expected-digest` can bind a load to a prior selection digest. Source, trigger content, routing-policy version, profile, mode, exclusions, session, task revision, phase, and a digest of the query invalidate stale reuse. A pending proposal cannot be reused as a completed decision. Receipts are integrity checks for local operation, not an authorization signature. + +An agent can call the resolver at task boundaries and read the returned context. This integration is prompt-advisory. Returning a body never grants tools, invokes shell interpolation, starts a native skill, changes hooks or installs dependencies. Native manual-only flags and authority-bearing metadata are checked before selection. Base profiles remain stable during task routing. + +`run` is the explicit task-launch boundary. Ambiguous Auto routing makes one provider proposal call over candidate IDs and descriptions. It accepts zero or one known candidate, then rechecks source bindings, saved state, exclusions and admission policy before loading bodies. Invalid or stale proposals stop before task execution. The proposal has a 30-second timeout and 64 KiB output bound. Codex uses an ephemeral, filesystem-read-only agent session with inherited tools and configuration; the prompt's request to avoid tools is advisory, not enforced tool isolation. Claude disables tools and session persistence for this proposal. Task text is sent to the configured provider, so its normal authentication and data-handling policy apply. + +The task call sends the query and selected reference content on standard input to `codex exec -` or `claude --print`, with no added task permissions or hook overrides. Current-provider launches inherit the provider process environment. An isolated native launch passes only the pinned home paths, `PATH`, a fixed locale, a private temporary directory, and required Windows system root; caller credentials, proxy settings, runtime injection and unrelated secrets are excluded. Its timeout is 90 seconds after a proposal or 120 seconds without one, uses an uncatchable termination signal, and captures at most 1 MiB. Dry run reports the pending proposal without a provider call. A zero provider exit code records process completion; task success and native skill invocation remain unverified. Routine interactive turns outside this launcher do not gain automatic routing. + +## Isolated native Codex generations + +`prepare-native` registers the managed carrier in a fresh ECC-owned home, verifies exact discovery through the allowlisted Codex 0.154.0 or 0.155.1 binary, and only then selects that native generation. It writes a bounded `AGENTS.md` bootstrap bound to the installed CLI source, managed roots, carrier, executable and receipt. It copies no credentials or user configuration and never rewrites the user's provider home. `native-status` checks the recorded generation, executable fingerprint, bootstrap source identity and managed-store binding. A launch pins that verified binary instead of resolving a different executable from PATH. Explicit preparation can refresh a changed executable or installed-source binding while preserving the prior generation and receipts. + +`profile start` is an explicit terminal-only boundary. It revalidates the store and native generation, then launches the pinned Codex binary with inherited terminal capabilities and the isolated home. The bootstrap tells the active agent to resolve context at material task boundaries through bounded structured stdin. It remains prompt-advisory, grants no tools or permissions, and persists no task prose or selected skill bodies. Authentication must be completed separately inside the isolated home; the start path does not inherit or copy provider credentials. + +Switching the managed profile makes the old native generation stale until `prepare-native` succeeds. To undo a switch, first `rollback` the managed store, then use `native-rollback` with both roots. `native-recover` handles a retained interruption journal without deleting provider data. Existing sessions retain their original context. These commands support isolated Codex generations, not migration of an existing global installation or native activation for other providers. + +Discovery evidence comes from the generation's empty project. Task launch inherits the caller's task working directory, whose repository instructions and native configuration may add context or affect policy. Native readiness attests the isolated home's recorded inventory and integrity, not the complete context or permissions of every possible task directory. + +## Outcome-evaluation pilot + +`docker/context-profiles/ai-eval.js` is a development-only evaluator; it lives outside the published package. It preregisters a fixed corpus before any provider call, binding the corpus, profile plans, registry, implementation, Node runtime, dependency versions, model and executable digests. It supports isolated Claude skill installs for five arms, including a pinned legacy skill-library comparator, and isolated Codex Lean/Full installs without that legacy arm. A hidden grader enters each workspace only after the agent exits and runs read-only where Node supports its permission model. + +Real execution requires an explicit flag and provider authentication. Codex uses a dedicated subscription login home (`--auth-home`) or `CODEX_API_KEY`; Claude uses its configured token or Keychain login. A Codex subscription login is leased into each isolated call home, refreshed tokens are returned to the login home, and the leased copy is always removed. The evaluator never reads or copies the user's own Codex home. Results contain allowlisted metrics and hidden-check verdicts, not prompts, transcripts, paths or credentials. See `context-profile-ai-evaluation.md` for the setup, measurement contract and statistical limits. + +## Community integration + +Jeffrey Montoya's [#2788](https://github.com/affaan-m/ECC/pull/2788) informed whole-tree staging, ownership receipts and reversible generations.

Source PR disposition remains separate. + +## Remaining release gates + +The store recovers actual process exits at five durable boundaries: prepared journal, file publication, generation publication, receipt publication and state publication. An interruption before the initial ownership marker is published, or a corrupted partial kernel write, is preserved for inspection. These cases do not receive an automatic recovery claim. + +Small authenticated Claude pilots now provide task and token observations, but they are descriptive and the evaluation gate remains `review-required`. Adequately powered task-quality canaries and whole-context measurements need additional evidence. The opt-in interactive bootstrap has local source, discovery and terminal-start evidence, but authenticated task behavior and native skill invocation remain unobserved. Isolated Codex registration, switching, refresh and rollback have local native evidence; changing a live user installation still requires its own ownership and recovery contract. Fresh-install default changes, existing-user migration, other-provider activation, hook plans, ECC Tools compatibility, hosted rollout and package publication remain outside this local preview. diff --git a/docs/design/context-profile-delivery.tdd.md b/docs/design/context-profile-delivery.tdd.md new file mode 100644 index 000000000..725eb94a2 --- /dev/null +++ b/docs/design/context-profile-delivery.tdd.md @@ -0,0 +1,91 @@ +# ECC-029 verification ledger + +September 13 baseline branch: `feat/ecc-029-profile-delivery`, incorporating upstream main `8321021c` and the previous carrier branch.

Model-driven task success, native skill invocation and token savings remain unobserved; there is no certified routing-quality percentage. + +Native readiness attests the isolated generation and discovery in its empty project. Task launch inherits the actual working directory and its repository controls, so complete task-context equivalence is unverified. Codex proposal execution is filesystem-read-only but inherits provider tools; tool avoidance in its prompt is advisory. Claude proposal tools are disabled. Task execution inherits provider policy and requires normal authentication. + +The store recovers actual process exits at five durable boundaries. Initial creation interrupted before its ownership marker, corrupted partial writes and numeric filesystem identity precision retain explicit limitations. Live installer migration, other-provider activation, interactive Auto bootstrap, whole-context outcome evaluation and default/release changes remain delivery gates. Native status never claims that an existing session changed context. + +## September 21 production-acceptance continuation + +Branch: `feat/ecc-029-production-acceptance`, with the working integration snapshot updated to upstream main `43b3a01e`. The writer session stopped at its provider usage limit after integrating the interactive and evaluation slices. A replacement session recovered the exact tmux transcript, process state, task log and worktree before continuing. No test process was still running and no conflicting writer remained active. + +Additional RED/GREEN cases cover gaps found during review: + +- Complete skill names in questions, quoted data or negated requests previously triggered implicit loading. Names now create candidates only; a user explicit ID or admitted agent proposal is required. +- A pending receipt could previously be reused and skip the provider decision. Receipts now bind routing-policy version and `selected`, `none` or `pending` decision state; only completed decisions can be reused. +- A changed or removed pinned Codex executable could leave native preparation unable to refresh. Explicit preparation may create a newly verified generation while preserving the old receipt and pointer until publication. Ordinary status and start remain fail-closed. +- Isolated native task launch previously inherited every caller environment variable. It now passes only pinned home paths, `PATH`, a fixed locale, a private temporary directory and the required Windows system root. Regression coverage proves unrelated cloud credentials, API keys, proxy settings and `NODE_OPTIONS` are absent. +- The Auto authority check previously missed the shipped `tools` frontmatter field. Scalar and array forms now require manual selection. Malformed task JSON now returns a fixed error without echoing task bytes. +- Provider and sandbox timeouts previously used a catchable termination signal. Launch, proposal, native discovery and sandbox supervision now use `SIGKILL`; a real subprocess that ignores `SIGTERM` verifies the sandbox bound. +- The acceptance driver previously trusted only the sandbox exit code. It now binds the executable and its complete implementation tree, rechecks both identities across preview and execution, and validates backend, tier, real execution, assertion commands, final smoke payload, architecture, layout matrix and evidence boundaries. + +The opt-in interactive slice adds bounded UTF-8 task JSON on stdin, receipt-bound bootstrap instructions, installed-source and executable identity checks, exact Codex 0.154.0/0.155.1 version admission, safe refresh, and `profile start`. A real macOS arm64 Codex 0.155.1 run verified Lean, an explicit include, Full with an exclusion, relocated resource digests, stdin resolution, bootstrap visibility, sign-in-screen startup and removed-binary refresh. No credential was copied and no authenticated task turn was made. + +The source-only AI pilot fixes 13 selection probes and eight paired artifact tasks before execution. Registration binds corpus, registry, plans, implementation, Node runtime, pinned parser and validator dependency versions, model and binary. The provider adapter uses disposable homes, explicit opt-in, `CODEX_API_KEY`, bounded JSONL, deadlines and call counts. Independent artifact assertions and sanitized metrics are implemented. Synthetic tests validate the measurement path; they do not establish model quality. The 13/8 pilot remains below the 30/30 gate and therefore reports `insufficient-sample` even if every case passes. + +Current combined verification after recovery: + +- Focused registry, carrier, store, native, interactive, resolver, admission, evaluation, sandbox and CLI suites pass, including the review regressions above. +- The final focused `node:test` run passes 182/182. Claude migration and setup compatibility suites pass 16/16 and 30/30. The complete repository runner passes 4,940/4,940; lint, diff checks and the production dependency audit all pass with zero vulnerabilities. +- The integration snapshot is current with upstream main `43b3a01e`. The latest-main Claude setup change removed obsolete install flags; migration dry-run and setup expectations now match the shipped command while retaining separate settings preservation. +- Clean commit `cda9c4bf` produced package SHA-256 `2ebc804ffc4f4c89fcf4b5ea0a9f644613618c1508292ef9199928157aa228d1`; both final driver receipts record that exact revision with `sourceDirty: false`. +- Real Tier 1 run `ecc-profile-tier1-89ead327-f193-4959-aff4-67cf8d381df3` passes on rootless Podman with a validated final smoke payload, a complete 10,758-added/4-changed layer diff, no credentials and exact cleanup. +- Real Tier 2 run `ecc-profile-tier2-fd4654a2-18b2-45f4-ba87-b8d0cd8bc488` passes on a disposable native macOS arm64 Lume clone with the same package digest. It validates all ten layouts, isolated Codex discovery, no credential transfer, stopped-guest cleanup and artifact-server cleanup. Lume v1 reports a bounded path scan with 49 added and nine changed files; it explicitly does not claim a complete disk diff. +- The initial Tier 2 attempt exposed `/tmp` as the standard macOS symlink to `/private/tmp`. The acceptance verifier now canonicalizes its newly created private directory while the production managed-store guard continues to reject symlinked roots. A second guest run proved the corrected path. +- The default sandbox checkout's 5,000-path capture limit truncated a real Tier 1 install diff and failed closed. The reviewed ECC-029 sandbox implementation raises the bounded cap to 50,000, passes its 26-case boundary suite, and produced both final reports. The driver receipt binds its 51-file implementation digest `a84e09ab848b8cd05f33792c13734f7aabe16bfe16d50d8f8292eb5261a93c3a`. +- No real AI outcome call ran because `CODEX_API_KEY` was absent. Host ChatGPT authentication was neither copied nor exposed to the disposable evaluator. + +These boundaries keep the shipped behavior distinct from the M1 release gate. Authenticated outcome observations, a complete Tier 2 disk diff, live-install migration, other-provider activation, whole-context token truth and release defaults remain unverified until their explicit prerequisites are available. diff --git a/docs/design/context-profiles.md b/docs/design/context-profiles.md new file mode 100644 index 000000000..5c67246eb --- /dev/null +++ b/docs/design/context-profiles.md @@ -0,0 +1,153 @@ +# Context profiles: read-only foundation + +Status: accepted first development slice, P0/P1, September 8, 2026.

These commands neither invoke skills nor write installed settings. The CLI reads its own package sources, independently of the caller's working directory. + +CLI preview defaults are `lean@1`, target `codex`, and selection intent `auto`. These are preview defaults, not detected user preferences. The library compiler defaults selection intent to `manual`; consumers should pass the intended value explicitly. Both `lean` and `full` are accepted aliases for the versioned profile IDs. + +JSON responses use `ecc.profile-inspection.v1`, including `status`, `summary`, `activation`, `next_actions`, and `artifacts`. A successful preview deliberately reports `status: "warning"` with exit code 0 because runtime activation remains `unobserved`. Invalid requests return an error and exit code 1.

The registry also exports `projectionFor(entry, target)` for already validated entries and targets. Consumers should use the loading and compilation APIs instead of duplicating source parsing or building another profile authority. + +## Inventory and selection semantics + +Each canonical `skills//SKILL.md` becomes `skill:`. Its skill directory must have exactly one owner in [install modules](../../manifests/install-modules.json). The owning module supplies `ownerModuleId`, the initial `packId`, and `declaredInstallTargets`. This reuses existing ownership without treating installer module dependencies as skill workflow dependencies. + +Lean currently selects three required candidate entries: `skill:configure-ecc`, `skill:context-budget`, and `skill:ecc-guide`. Other canonical skills remain labeled `routed` unless explicitly included or excluded. Here, `routed` means available in the catalog for future discovery integration; it does not mean a router has run or a native host can already retrieve the skill. + +Full derives `all` from the current canonical inventory. The September 8 baseline contains 286 skills, but 286 is a snapshot, not a hardcoded profile limit. Explicit exclusions can narrow a Full proposal, except for required entries and dependencies needed by retained selections. + +Includes add exact IDs and their transitively declared dependencies. Exclusions cannot remove required profile entries or break that declared closure. Unknown IDs, duplicate selectors, overlapping include/exclude requests, unknown targets, and invalid selection modes fail. Profiles must include their declared required entries in the eager selection. + +Dependencies come only from `overrides[].dependencies` in the registry declaration. The current manifest has no overrides, and entries report `dependencyCoverage: "declared-only-unreviewed"`. An empty dependency array means no declaration exists; it does not prove that a workflow is self-contained. References in skill prose are not followed, interpreted, or promoted into dependency edges. + +`overrides[].requiredResources` can assert that files exist within that skill's own directory. Unknown override IDs, duplicate ownership, missing resources, unknown dependencies, cycles, malformed metadata, unsafe paths, and symbolic links within the source tree are rejected. Reads are bounded at 4 MiB per file, 16 MiB per source reader, 10,000 files, and 32 levels of recursive directory depth. Directory enumeration is incremental, with at most 10,000 accepted names per directory and 20,000 traversal operations per reader. Every directory open and enumerated entry consumes that shared budget, including empty directories and excluded names; detecting overflow may inspect one extra entry. Generated Python caches, `.git`, and `node_modules` are excluded; an explicitly required excluded resource is rejected. + +P2a adds sorted explicit `requiredResources` to registry and plan entries. The mandatory `sourcePath` entrypoint remains distinct; effective required paths are their union. Empty declarations do not establish resource closure, and carriers must not infer that arbitrary subsets are sufficient. The first carrier implementation projects all bundled files for selected skills; see the [P2 carrier contract](context-carriers.md). + +Source reads revalidate ancestor and file identities before consuming bytes and after reading. These consistency checks reject the tested concurrent symlink substitution; they do not provide an atomic repository snapshot. Use immutable source artifacts for downstream execution. Skill and profile metadata reject terminal controls; CLI text also renders controls inert in error paths. + +## Provenance without eager instruction loading + +The registry reads and hashes skill bodies and bundled resource bytes to bind source identity. It does not evaluate scripts, follow instructions in prose, or emit those bodies as model context. Discovery metadata and resource descriptors are separate from instruction loading. Future native carriers must preserve on-demand loading of selected skill bodies and required resources; this first slice implements no native loader. + +| Digest | What it binds | +| --- | --- | +| Resource `digest` | Exact bytes of one source file | +| Entry `contentDigest` | Ordered resource descriptors, including paths, byte counts, and resource digests | +| `registryDigest` | Portable registry output, including inventory-source digests, ownership, metadata, and resource descriptors | +| `profileDigest` | Normalized profile manifest, with selection arrays sorted | +| `compilerDigest` | Source digests for the three compiler library files, two declaration schemas, and the existing install-manifest module supplying target IDs | +| `planDigest` | Complete portable proposed-plan object before adding `planDigest` itself | + +These are SHA-256 content bindings, not signatures, runtime attestations, or a complete execution-environment identity. Digests deliberately exclude caller-specific absolute paths and timestamps. Equivalent selector ordering produces identical plans; changing a skill body changes provenance even when its discovery-metadata estimate stays constant. + +## The 8K check is a metadata fixture gate + +`estimate.surface` is `skill-discovery-metadata`. Method `utf8-bytes-div-4@1` renders each selected entry as canonical JSON containing `harness`, `type`, `name`, and `description`, adds a newline, divides UTF-8 bytes by four, rounds each entry up, and sums the results. The ledger exposes per-entry costs. + +Lean rejects estimates above 8,000 using `CONTEXT_PROFILE_BUDGET_EXCEEDED`; a library caller can inspect the rejected proposal on `error.plan`. Exactly 8,000 passes the estimator check; 8,001 fails. Full uses the same reference budget in report-only mode. + +This heuristic is an early rejection and regression fixture, not a tokenizer, measured lower bound, or whole-prompt certification. Passing cannot establish the production Lean startup ceiling. `nativeTokens`, `wrapperTokens`, and `wholeScopeTokens` remain `null` until appropriate observation exists. + +The registry explicitly excludes agents, commands, rules, hooks, MCP schemas, harness wrappers, and learned skills. Skill bodies and bundled resources are hashed but excluded from the discovery estimate. Other plugin context, host overhead, repeated prompts, and task execution costs are also unmeasured. Report observed native counters separately and avoid deriving savings claims from this ledger alone. + +## Target declarations are not runtime certification + +The registry recognizes the current 15 install target IDs plus Pi. For a requested target, `projection.installSupport` reports `declared` or `not-declared` according to the owning module. `projection.nativeSupport` remains `unobserved` in both cases. + +Target selection does not silently drop skills lacking an installer declaration. The same explicit skill selection is projected for every recognized target, so consumers can inspect gaps rather than mistake them for successful installation. Native discovery, invocation, resource access, reload behavior, exclusion enforcement, and whole-context cost require adapter-specific evidence in later slices. + +## Rationale and alternatives + +The read-only boundary makes the selection contract reviewable before it can alter user state. Versioned manifests and source digests provide shared inputs for adapters, grouping work, routing, and measurement. Keeping existing install ownership avoids a second independently maintained inventory. + +Alternatives considered: + +- Reuse install profile names for runtime scope. Rejected because installed files, visible context, hooks, and permissions are separate controls with existing compatibility obligations. +- Start by rewriting plugin caches or installed discovery files. Deferred until carrier ownership, fresh-session behavior, receipts, rollback, and user-edit preservation have evidence. +- Treat a task classifier or system prompt as the enforcement boundary. Rejected. Future agent proposals must be validated against deterministic contracts and retained consent. +- Infer complete workflow closure from Markdown prose. Rejected as an unreviewed authority source. Explicit declarations are auditable; the current dependency coverage remains incomplete. +- Declare 8K compliance from a character or byte estimate. Rejected. Metadata fixtures help catch regressions while native host measurements remain a separate gate. + +## Contributor integration lanes + +These related PRs are integration inputs, not claims that their proposed behavior has shipped.

No package was published or globally installed. + +The packaged dispatcher produced Lean and Full Codex previews, and the packaged direct entrypoint explained an exact skill ID. Both full proposed-plan objects were deeply equal to their checkout counterparts, including registry, profile, compiler, and plan digests.

Source identity checks do not create an atomic filesystem snapshot. The initial checkpoint lacked an independent directory listing bound; the hosted-review follow-up below closes that gap. Dependency coverage remains explicit-declarations-only and unreviewed. Required-resource annotations need a distinct output contract before selective P2 carriers can safely omit resources. + +The js-yaml integration prerequisite from contributor [PR #3032](https://github.com/affaan-m/ECC/pull/3032) is satisfied on this branch by the attributed 4.3.2 upgrade, fresh install, zero-vulnerability runtime audit and packed-consumer verification described below. Its original PR remains open; final hosted CI and release qualification are separate gates. See the [contract's dependency gate](context-profiles.md#contributor-integration-lanes). + +Native carriers, active discovery, actual skill invocation, transactional activation, hook consent, automatic task routing, recovery, real-host token counters, broader context surfaces, cross-platform conformance, and default migration remain follow-on work. No provider calls, container or VM launches, or runtime profile changes were used to establish these results. + +## PR-readiness follow-up + +Independent exact-head review approved the read-only implementation and identified privilege-sensitive symlink fixtures. Review's original permission-denial injection produced 12 passes and 3 failures. Checkpoint `88f5a996` added a failing portable directory-link contract: 15 passes and 1 expected failure. The fix uses Windows junctions for directory cases, separates unconditional ownership and mocked leaf-link rejection from the real file-link integration case, and explicitly skips only that extra file-link case on Windows EPERM/EACCES. No runtime code changed. + +Final local focused checks now pass 30 library, 25 CLI, and 3 CI cases. A bounded simulation of Windows file-link denial, keeping the local temporary directory fixed and emulating directory junctions, passes 17 registry cases and explicitly skips 1 real file-link case. It is a test-policy simulation, not native Windows evidence. The source-read substitution and zero-byte-read assertions remain mandatory. + +An isolated Git archive passed `YARN_ENABLE_HARDENED_MODE=1 YARN_ENABLE_SCRIPTS=false yarn install --immutable --mode=skip-build`; both package manifest and Yarn lockfile remained byte-identical. The initially attempted immutable/update-lockfile combination was rejected by Yarn as incompatible before installation; the immutable skip-build run is the applicable successful CI check. Dependency declarations remain unchanged. Source-only evidence/test links in the shipped contract are now labeled explicitly. + +### Contributor security prerequisite + +Hosted CI for PR #3037 at `78cbd01c` reproduced the existing js-yaml high-severity advisory in its runtime audit. The branch incorporated contributor Myles Agnew's exact commit `5674661fc30ab1d3f3fcae22d72bfb4ab3059822` from #3032 using an attributed cherry-pick (`77872972`).

A fresh dependency install resolved js-yaml 4.3.2, and `npm audit --omit=dev --audit-level=high` reports zero vulnerabilities. + +The local npm 11 install unexpectedly rewrote the Yarn lock into its legacy format. Only that task-induced rewrite was restored to the committed contributor bytes before subsequent validation. This is installation-tool behavior, not an intended lockfile change. The full test run started on the preceding revision overlapped the dependency update and is excluded from exact-final-head evidence; final PR checks must bind to the updated head. + +### Hosted review regressions + +The global dry-run parser regression was reproduced before implementation in `c373b7fe`: 27 CLI cases passed and 4 failed. Fix `9b5e3934` removes exact global `--dry-run` flags before command/value parsing, without mutating caller arguments or weakening other validation. All 31 CLI cases and seven independent parser probes pass. Both public entrypoints retain unobserved activation. + +Checkpoint `ea00894d` adds seven source-reader regressions for incremental enumeration, the exact per-directory boundary, empty-directory breadth, excluded cache names, handle cleanup and directory identity changes. The corrected reader accepts at most 10,000 names per directory and charges every directory open and enumerated entry against a 20,000-operation reader budget, allowing one lookahead to detect overflow. It retains the file, cumulative-byte and depth bounds. Focused support/registry/compiler checks pass 37/37, including the mandatory ancestor-substitution test with zero redirected file-byte reads. + +The source reader was split into focused helpers below 50 lines. Directory handles close in `finally`, and identities are revalidated before and after enumeration. Independent review checked that descriptor no-follow flags, identity checks before the first file byte, post-read checks and exact byte digests survive the extraction. This remains a bounded consistency check, not an atomic filesystem snapshot. diff --git a/docs/ja-JP/README.md b/docs/ja-JP/README.md index ec59cf67a..00cc8b62f 100644 --- a/docs/ja-JP/README.md +++ b/docs/ja-JP/README.md @@ -376,7 +376,7 @@ cd ECC | Qwen CLI | `./install.sh --profile minimal --target qwen` | [Qwen ガイド](../QWEN-GUIDE.md)を参照 | | Hermes | `./install.sh --profile minimal --target hermes` | [Hermes セットアップガイド](../HERMES-SETUP.md)を参照 | | OpenClaw | `./install.sh --profile minimal --target openclaw` | 管理されたホームディレクトリインストール | -| Kimi Code CLI | `./install.sh --profile minimal --target kimi` | プロジェクトローカルの `.kimi-code/` インストール · [Kimi Code を入手](https://www.kimi.com/code?aff=ecc) | +| Kimi Code CLI | `./install.sh --profile minimal --target kimi` | プロジェクトローカルの `.kimi-code/` インストール · [Kimi Code を入手](https://www.kimi.ai/code?aff=ecc) | | CodeBuddy | `./install.sh --profile minimal --target codebuddy` | プロジェクトローカルの `.codebuddy/` インストール | | JoyCode | `./install.sh --profile minimal --target joycode` | プロジェクトローカルの `.joycode/` インストール | diff --git a/docs/tr/the-shortform-guide.md b/docs/tr/the-shortform-guide.md index 9e20acda0..6a894a175 100644 --- a/docs/tr/the-shortform-guide.md +++ b/docs/tr/the-shortform-guide.md @@ -420,7 +420,7 @@ affoon:~ ctx:65% Opus 4.5 19:52 - [Interactive Mode](https://code.claude.com/docs/en/interactive-mode) - [Memory Sistemi](https://code.claude.com/docs/en/memory) - [Subagent'lar](https://code.claude.com/docs/en/sub-agents) -- [MCP Genel Bakış](https://code.claude.com/docs/en/mcp-overview) +- [MCP Genel Bakış](https://code.claude.com/docs/en/mcp) --- diff --git a/docs/zh-CN/the-shortform-guide.md b/docs/zh-CN/the-shortform-guide.md index e662afa28..f5dcbb55d 100644 --- a/docs/zh-CN/the-shortform-guide.md +++ b/docs/zh-CN/the-shortform-guide.md @@ -421,7 +421,7 @@ affoon:~ ctx:65% Opus 4.5 19:52 * [交互模式](https://code.claude.com/docs/en/interactive-mode) * [记忆系统](https://code.claude.com/docs/en/memory) * [子代理](https://code.claude.com/docs/en/sub-agents) -* [MCP 概述](https://code.claude.com/docs/en/mcp-overview) +* [MCP 概述](https://code.claude.com/docs/en/mcp) *** diff --git a/eslint.config.js b/eslint.config.js index 788a502b5..22f924aff 100644 --- a/eslint.config.js +++ b/eslint.config.js @@ -30,5 +30,11 @@ module.exports = [ languageOptions: { sourceType: 'module' } + }, + { + files: ['docker/context-profiles/complex-eval/**/recurring-incident/**/*.js'], + languageOptions: { + sourceType: 'module' + } } ]; diff --git a/install.sh b/install.sh index c69a11dd7..8d6aaa9c5 100755 --- a/install.sh +++ b/install.sh @@ -4,6 +4,14 @@ # This wrapper resolves the real repo/package root when invoked through a # symlinked npm bin, then delegates to the Node-based installer runtime. +# Re-exec under bash if invoked via a POSIX sh (e.g. `sh install.sh`), since +# the rest of this script relies on bash features (`set -o pipefail`, `[[`). +# Probe actual shell capability instead of trusting $BASH_VERSION, which is +# just an environment variable and could be inherited/spoofed under sh. +if !

Never start another model or agent solely to choose skills. + +Honor the saved profile, selectionMode, includes, and exclusions. Manual uses only explicit user-requested IDs; Suggest returns recommendations without loading bodies; Auto permits bounded admitted proposals. Do not override the saved mode. Inspect the resolver result and only consume returned resources. To load an admitted selection, repeat the same structured input with --load and --expected-digest set to the returned receipt.selectionDigest.
