The session uses the existing Claude login or +`ANTHROPIC_API_KEY`/`CLAUDE_CODE_OAUTH_TOKEN`; the harness never reads +credential files. The prompt is the scenario prompt plus one line asking the +agent to work without clarifying questions. + +After the session exits, the grader is copied in and run with Node's +permission model (read-only on the workspace where Node supports it). Graders +print a score from 0 to 1; only a full score passes, and a grader that crashes +scores 0. + +A gate arm whose agent edited files without any sign of the gate (no metrics +line and no denial in the transcript) stops the run, so a broken hook setup +does not spend the remaining sessions. + +## Measures + +Per trial (`results.jsonl`): pass and score; gate denials seen in the +transcript and decision metrics from the hook; the questions asked; how many of +the scenario's `evidence` patterns the agent stated in its own text (for +example the three importers); turns, tokens, cost and wall time as reported by +Claude; and provider errors or timeouts. The full transcript of each trial is +kept in `transcripts/`. + +## Analysis + +Arms run in a seeded shuffled order inside each scenario and repetition, so +drift over the run affects them alike. `summary.md` reports per arm the pass +rate with a Wilson 95% interval, mean score, evidence stated, median denials, +turns, tokens and cost; per scenario the passes in each arm; and for each arm +against `gate`, paired by scenario and repetition, the pass-rate difference +with a 95% bootstrap interval and an exact McNemar test on the discordant +pairs. Provider errors and timeouts are counted but left out of comparisons. + +## Reproduce + +```bash +node docker/gateguard-effectiveness/run.js --out gg-eff --dry-run +node docker/gateguard-effectiveness/run.js --out gg-eff --model --allow-real-provider +node docker/gateguard-effectiveness/run.js --out gg-eff --summarize +node tests/docker/gateguard-effectiveness.test.js +``` + +A rerun with the same `--out` resumes; changing the model or commit needs a new +folder. `--arms off,gate,main` compares the routing of two commits. + +## Limits + +- The traps and graders were written by the author of the questions they + test.

From 7afde35e4936598266717885b49c39e96523da1a Mon Sep 17 00:00:00 2001 From: montjeffrey Date: Fri, 2 Oct 2026 09:53:08 -0400 Subject: [PATCH 03/19] feat(gateguard): measure question effectiveness against a hidden user intent The existing harness cannot measure what it set out to measure. Every trap hides its deciding fact in the repository, which agents reliably discover, and trials run one-shot under "do not ask clarifying questions", so a fact-forcing gate is evaluated with no user to answer it. Its scenarios also declare the question the gate ought to raise, chosen by reading the gate's own taxonomy, so the suite passes by construction and can never find a missing question. Add a second runner that measures effectiveness instead of coverage: - scenarios-intent/ keeps the deciding fact in intent.json, as a choice between plausible conventions the repository cannot settle, so an agent that does not ask can only guess and the ungated arm cannot sit at the ceiling. - user-sim.js plays that user with a separate cheap model: it answers the question in front of it, never volunteers, and reports which fact ids it disclosed, so asking something and asking the deciding thing are told apart. An unparseable judge is a recorded failure, not a silent stonewall. - session.js runs multi-turn sessions joined by --session-id and --resume, and tells every arm the user is reachable, so the comparison is symmetric and the gate's contribution is whether it makes the agent ask the deciding question. - coverage.js classifies each trial from behaviour alone into working, lucky, or a follow-through, targeting, silence or coverage hole, and reports the questions the gate actually raised rather than asserting declared ones. - run-intent.js refuses minus-target, which needs targets these scenarios deliberately lack, and checks every grader separates the start, the trap and the reference before a session is billed. A scenario counts as carrying no information only when nothing varies across arms. Trap strength is reported separately: the ungated arm failing is what a working trap looks like, so it must not make a scenario unusable. --- docker/gateguard-effectiveness/README.md | 20 ++ docker/gateguard-effectiveness/coverage.js | 172 ++++++++++ docker/gateguard-effectiveness/intent-eval.js | 128 ++++++++ docker/gateguard-effectiveness/run-intent.js | 231 ++++++++++++++ .../audit-retention-purge/grader.cjs | 39 +++ .../audit-retention-purge/intent.json | 23 ++ .../audit-retention-purge/naive/src/audit.js | 25 ++ .../reference/src/audit.js | 26 ++ .../audit-retention-purge/task.json | 6 + .../workspace/config/retention.json | 3 + .../workspace/package.json | 5 + .../workspace/src/audit.js | 11 + docker/gateguard-effectiveness/session.js | 139 ++++++++ docker/gateguard-effectiveness/user-sim.js | 94 ++++++ tests/docker/gateguard-intent.test.js | 297 ++++++++++++++++++ 15 files changed, 1219 insertions(+) create mode 100644 docker/gateguard-effectiveness/coverage.js create mode 100644 docker/gateguard-effectiveness/intent-eval.js create mode 100644 docker/gateguard-effectiveness/run-intent.js create mode 100644 docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/grader.cjs create mode 100644 docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/intent.json create mode 100644 docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/naive/src/audit.js create mode 100644 docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/reference/src/audit.js create mode 100644 docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/task.json create mode 100644 docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/workspace/config/retention.json create mode 100644 docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/workspace/package.json create mode 100644 docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/workspace/src/audit.js create mode 100644 docker/gateguard-effectiveness/session.js create mode 100644 docker/gateguard-effectiveness/user-sim.js create mode 100644 tests/docker/gateguard-intent.test.js diff --git a/docker/gateguard-effectiveness/README.md b/docker/gateguard-effectiveness/README.md index 6b7f9c298..3aa3770cb 100644 --- a/docker/gateguard-effectiveness/README.md +++ b/docker/gateguard-effectiveness/README.md @@ -4,7 +4,27 @@ Development-only harness that runs real Claude sessions on trapped coding tasks with and without GateGuard's questions.

The existing test, the CSV's later rows and + the `.env` convention are the same shape. Agents are reliably good at + discovering repository facts, so the gate was measured where it cannot help. +2. **The asking channel was switched off.** Trials ran one-shot with "Work + autonomously in this repository and do not ask clarifying questions". A + fact-forcing gate was evaluated with no user to answer it, so the only + mechanism left was the agent restating facts to itself. +3. **The checks could not fail.** Each scenario declared `targetQuestions`, and + the suite asserted the gate asks one of them for the reference edits. Those + targets were chosen by reading the gate's own question taxonomy, so the + assertion held by construction. The scenario set was likewise built around + the six questions the gate already had, so the design could only confirm + existing coverage and never discover a missing question. + +The first `Limits` bullet anticipated (1) and (3) in part. It understated them: +the problem is not only that the author wrote both sides, but that the pass +criterion referred to the gate's own vocabulary. + +## Hidden-intent evaluation + +`docker/gateguard-effectiveness/scenarios-intent/` and `run-intent.js` answer a +different question, and are built so that a null result cannot be manufactured +by construction. + +**The deciding fact is only in the user's head.** Each scenario carries an +`intent.json` holding an ambiguity the repository cannot settle and the facts +that resolve it, each marked `decisive` or not. `audit-retention-purge` asks for +"our audit retention policy" to be applied; the workspace offers +`config/retention.json` with `sessionDays: 30` and no audit key, while the real +policy is 400 days and a soft mark. Nothing in the tree says so, so an agent +that does not ask can only guess, and the ungated arm cannot sit at the ceiling. + +**A simulated user answers only what is actually asked.** `user-sim.js` runs a +separate cheap model holding the facts, under instructions to answer the +question in front of it, never volunteer, and otherwise repeat a stonewall line. +It reports which fact ids it disclosed, so "asked something" and "asked the +deciding thing" are distinguishable. A judge whose reply cannot be parsed is +recorded as a judge failure rather than silently read as a stonewall. + +**Sessions are multi-turn and symmetric.** `session.js` joins turns with +`--session-id` and `--resume`. Every arm, gated or not, is told the user is +reachable, so the gate's contribution is whether it makes the agent ask the +deciding question — not whether asking was permitted. + +**Scenarios are authored blind.** `task.json` must not declare +`targetQuestions`; the loader rejects it. Which questions a scenario provokes is +observed from the run and reported. + +### Hole classes + +Each trial is classified from behaviour alone — whether the gate fired, whether +the agent asked, whether the deciding facts came out, and whether the outcome +was right.

ESLint rejected an unused `armSettings` import in intent-eval.js; the caller supplies `armSettingsByName` already. A timeout was lost whenever a later turn came back clean: `a || b ? c : false` evaluates the condition first, so `timedOut` was recomputed from the new turn instead of being kept. Isolating each trial's config directory, to stop persisted sessions piling up under the projects folder, puts the credentials out of reach. Every turn then returns "Not logged in", and the harness graded that as a coverage-hole - an auth failure recorded as a finding. Keep the real config directory and delete only the session folders this run's work root created, and adopt lib.js's own guards: a trial that is unauthenticated, or whose gated arm edited files with no metrics line and no denial, stops the run instead of being recorded. Record denials per turn as well as in total. The hook marks a file checked once per session and --resume keeps one session id for the conversation, so a zero after a non-zero is the latch rather than the gate staying quiet, and silence-hole has to be read with that column in view.

GNU tar, which Git for Windows bundles and puts first on PATH in Git Bash, reads an -f argument containing a colon as a host:path remote spec and fails with "Cannot connect to C: resolve failed". bsdtar, the tar in system32 that PowerShell resolves, has no remote-spec parsing, so the fault only appeared under a bash-based shell - and there it failed a committed test, not just a dry run. Name the archive relatively and run tar with dest as its cwd, which extracts identically under both tars and makes -C unnecessary. git archive keeps the absolute -o path, which git handles on Windows. Two tests, because the environment-dependent kind of fault needs both: one injects a spawn and asserts no tar argument is absolute or drive-lettered, which holds the invariant on any platform; the other prepends Git's bundled GNU tar to PATH and extracts into a drive-letter destination, so the original failure is reproducible from PowerShell too, where it was previously invisible. --- docker/gateguard-effectiveness/arms.js | 20 +++++--- tests/docker/gateguard-effectiveness.test.js | 54 ++++++++++++++++++++ 2 files changed, 67 insertions(+), 7 deletions(-) diff --git a/docker/gateguard-effectiveness/arms.js b/docker/gateguard-effectiveness/arms.js index 9fb59a5bf..294968b45 100644 --- a/docker/gateguard-effectiveness/arms.js +++ b/docker/gateguard-effectiveness/arms.js @@ -45,8 +45,8 @@ function run(rawInput) { module.exports = { run }; `; -function git(repoRoot, args) { - const result = spawnSync('git', ['-C', repoRoot, ...args], { encoding: 'utf8', shell: false, timeout: 60000 }); +function git(repoRoot, args, spawn = spawnSync) { + const result = spawn('git', ['-C', repoRoot, ...args], { encoding: 'utf8', shell: false, timeout: 60000 }); if (result.status !== 0 || result.error) throw new Error(`git ${args[0]} failed: ${String(result.stderr || result.error).trim()}`); return result.stdout; } @@ -57,12 +57,18 @@ function resolveRef(repoRoot, ref) { } /** Extracts scripts/ at a commit into dest and adds the arm wrapper; returns dest. */ -function materializeTree(repoRoot, sha, dest) { +function materializeTree(repoRoot, sha, dest, spawn = spawnSync) { fs.mkdirSync(dest, { recursive: true }); - const tar = path.join(dest, 'scripts.tar'); - git(repoRoot, ['archive', '--format=tar', '-o', tar, sha, 'scripts']); - const extract = spawnSync('tar', ['-xf', tar, '-C', dest], { encoding: 'utf8', shell: false, timeout: 60000 }); - fs.rmSync(tar, { force: true }); + const tarName = 'scripts.tar'; + git(repoRoot, ['archive', '--format=tar', '-o', path.join(dest, tarName), sha, 'scripts'], spawn); + // Name the archive relatively and run tar with dest as cwd, so no argument carries a + // "C:\..." drive letter.

On this run it is not one: gate 1/2 against off 0/2 gives intervals of 9%-91% and 0%-66%, a paired difference of -50% with a 95% interval spanning -100% to 0%, and McNemar p = 1.000.

These five were written from ambiguities a developer meets, not from the gate's question list, and each keeps its deciding fact out of the repository while leaving a plausible wrong answer in plain sight: - csv-export-delimiter: a comma-parsing importer sits next to an export whose consumer needs semicolons, CRLF and every field quoted. - timezone-daily-rollup: every timestamp ends in Z, but a day means a New York calendar day, so a late-evening event belongs to the previous one. - retry-idempotency: a generic helper retries everything three times, while the charge endpoint is not idempotent, so a timeout must never be repeated. - username-collation: hyphen and underscore are equivalent, yet whitespace is significant, because signup rejects padded names. - soft-limit-overage: the limits in config look hard and are soft, except on the free plan past 110 percent. Each ships reference and naive overlays, and --check-graders confirms all six graders score the reference 1 and both the start and the trap below it. --- .../csv-export-delimiter/grader.cjs | 20

It was scoring whether the agent guessed field names, not whether it learned the policy. So each scenario now carries exactly one decisive fact, which is one hidden decision a single well-aimed question can obtain, and anything a grader checks about shape is stated in the prompt. The three working scenarios are changed the same way, so disclosedDecisive means the same thing across the corpus: their second and third decisive facts move into the prompt or become non-decisive colour. --- .../audit-retention-purge/intent.json | 22 +++++-------------- .../audit-retention-purge/task.json | 4 ++-- .../csv-export-delimiter/intent.json | 9 ++++---- .../csv-export-delimiter/task.json | 4 ++-- .../retry-idempotency/intent.json | 9 ++++---- .../retry-idempotency/task.json | 4 ++-- .../soft-limit-overage/intent.json | 5 ++--- .../soft-limit-overage/task.json | 4 ++-- .../timezone-daily-rollup/intent.json | 8 +++---- .../timezone-daily-rollup/task.json | 4 ++-- .../username-collation/intent.json | 7 +++--- .../username-collation/task.json | 4 ++-- 12 files changed, 34 insertions(+), 50 deletions(-) diff --git a/docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/intent.json b/docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/intent.json index 6e2b3a7f5..18ce03e8c 100644 --- a/docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/intent.json +++ b/docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/intent.json @@ -1,23 +1,11 @@ { "id": "audit-retention-purge", - "ambiguity": "You asked for the audit retention policy to be applied, but never said how long the window is or whether purged rows are removed or marked.", + "ambiguity": "You asked for the audit retention policy to be applied but never said how long the window is.", "facts": [ - { - "id": "window", - "fact": "Audit retention is 400 days.

Against that, the gate changes nothing measurable. Asked the user 14/24 against 15/24, obtained the deciding fact 14/24 against 14/24, passed 15/24 against 16/24, every exact McNemar p = 1.000, and the paired pass-rate difference 5 points in off's favour with a 95% interval of -25% to +35%. At 20 pairs a 40-point effect is ruled out; a 15-to-20-point one is not. The gate does fire - denials in 22 of 24 gated trials - so the failure is in the conversion. timezone-daily-rollup fired four times out of four and produced no question at all. Every question the gate raised is about code structure, while every deciding fact in this corpus is an external contract. Record the two scenario-design faults the earlier runs exposed, and the bound the correction imposes: moving shape into the prompt also signposts the ambiguity, which raises asking in both arms, so the claim is limited to the signposted regime. --- docs/gateguard/question-effectiveness.md | 85 +++++++++++++++++++----- 1 file changed, 69 insertions(+), 16 deletions(-) diff --git a/docs/gateguard/question-effectiveness.md b/docs/gateguard/question-effectiveness.md index 73beb315f..4a4a8c014 100644 --- a/docs/gateguard/question-effectiveness.md +++ b/docs/gateguard/question-effectiveness.md @@ -252,26 +252,79 @@ Graders are checked before any session is billed: the start workspace and the `naive` overlay must both score below 1 and `reference` must score 1, or the run stops. -### First hidden-intent run +### Hidden-intent results -Four trials, `off` and `gate`, two repetitions, sonnet under test and haiku as -the user: +Six blind-authored scenarios, `off` and `gate`, four repetitions, 48 trials, +sonnet under test and haiku as the user.

Three of six scenarios sat at floor before that +change and none does after it. + +The correction has a cost of its own, and it bounds the result. Moving shape and +constraints into the prompt also signposts the ambiguity: prompts now say "the +dialect our consumer expects" or "the calendar our reports are read against", +which invites a question in every arm. Ungated pass rates rose accordingly - +`retry-idempotency` reached 4/4 and is excluded as a ceiling, with +`csv-export-delimiter` and `soft-limit-overage` at 3/4. So the finding is +properly stated as: **where the ambiguity is already signposted, the agent asks +about half the time whatever the gate does.** Whether the gate helps when +nothing signposts the ambiguity is a different question, and this corpus no +longer asks it. ### Reproduce From b29823b435fb39446f67c49bbfe05f12ee382308 Mon Sep 17 00:00:00 2001 From: montjeffrey Date: Sat, 3 Oct 2026 13:28:29 -0400 Subject: [PATCH 13/19] test(gateguard): leave the ambiguity unflagged in every prompt The previous prompts signposted what they withheld - "the dialect our consumer expects", "the calendar our reports are read against", "retrying only the failures that are safe to repeat" - which invited a question in every arm and pushed ungated pass rates to 3/4 and 4/4. That bounded the result to a regime where the agent was already told something was missing. Each prompt now reads as an ordinary ticket. Shape a grader checks stays, since removing it would score field-name guessing instead of the hidden decision, but it is stated mechanically: checkQuota still documents { allowed, overage } and defines overage as how far usage exceeds the limit, which does not say whether exceeding it is allowed, so the soft-limit policy stays hidden. Graders, workspaces and intents are unchanged, so this isolates one variable: whether the gate changes behaviour when nothing cues the agent that a convention it cannot see decides the task. --- .../scenarios-intent/audit-retention-purge/task.json | 7 +++++-- .../scenarios-intent/csv-export-delimiter/task.json | 7 +++++-- .../scenarios-intent/retry-idempotency/task.json | 7 +++++-- .../scenarios-intent/soft-limit-overage/task.json | 7 +++++-- .../scenarios-intent/timezone-daily-rollup/task.json | 7 +++++-- .../scenarios-intent/username-collation/task.json | 7 +++++-- 6 files changed, 30 insertions(+), 12 deletions(-) diff --git a/docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/task.json b/docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/task.json index c820c7e11..437e1a92d 100644 --- a/docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/task.json +++ b/docker/gateguard-effectiveness/scenarios-intent/audit-retention-purge/task.json @@ -1,6 +1,9 @@ { "id": "audit-retention-purge", "trap": "config/retention.json holds sessionDays: 30 and no audit key, which invites a 30-day window.

With the prompts rewritten as ordinary tickets and nothing else changed, they separate: asked the user 16/24 against 10/24, obtained the deciding fact the same, passed 15/24 against 8/24, exact McNemar p = 0.065 to 0.070, and a paired pass-rate difference of 29 points in the gate's favour whose bootstrap interval excludes zero. The regime contrast carries it. The gated arm passed 15/24 in both runs while the ungated arm fell from 16/24 to 8/24, which is what removing the only cue that a convention was missing would do if the gate supplies that cue itself. Asking stayed necessary throughout: no trial in either arm passed without the deciding fact. Reported as suggestive rather than established. All three p-values sit just above 5%, one more gate-favouring discordant pair would cross it, and extending this run after seeing that would be optional stopping.

The headline reads gate 23/48 against off 13/48, a 21-point paired difference at exact McNemar p = 0.021, and it is an artifact. The scenarios, prompts, graders and model alias were identical to the previous run and the off arm has no gate, yet off fell from 18/48 to 13/48 while the gated arm went down, 25/48 to 23/48. An intervention meant to raise the gated arm did not raise it, so the p-value reflects a baseline that fell rather than a gate that improved. The two scenarios the question cannot reach, having no data for the profile to detect, serve as a control: they moved by -3 and +3, more than any of the four it did reach (-1, -1, +1, -1). Noise on eight trials is about plus or minus three, which is larger than any effect available to the change. The question is kept, since it asks something the gate never asked and the corpus says that kind of answer decides the outcome, but no improvement is claimed. Testing it fairly needs scenarios authored blind to it, which this corpus no longer is. --- docs/gateguard/question-effectiveness.md | 56 ++++++++++++++++++++++-- 1 file changed, 53 insertions(+), 3 deletions(-) diff --git a/docs/gateguard/question-effectiveness.md b/docs/gateguard/question-effectiveness.md index 2119eebfa..f6278b9e3 100644 --- a/docs/gateguard/question-effectiveness.md +++ b/docs/gateguard/question-effectiveness.md @@ -464,9 +464,59 @@ and roughly $48.
