* fix: add claude-opus-5 to KNOWN_MODEL_WINDOW_TOKENS
claude-opus-5 has a 1M context window (verified: 250k tokens at 25%
usage = ~1M), but was missing from the model table. This caused
resolveContextWindowTokens() to fall back to the 200k default when
tokens < 200k, incorrectly triggering compact warnings in the first
20% of a 1M session.
Same failure class as #2290 (Opus 4.x) and #2461 (fable-5/mythos-5).
The env override (ECC_CONTEXT_WINDOW_TOKENS) remains the escape hatch
for unlisted models.
Refs: #2290, #2461, #2468
* test: add regression test for claude-opus-5 context window
Verifies resolveContextWindowTokens returns LARGE_CONTEXT_WINDOW_TOKENS
for claude-opus-5 at 50k tokens, matching the behavior of fable-5 and
mythos-5 in the known-model table.
* fix(suggest-compact): recognize large-window model families without a [1m] marker
resolveContextWindowTokens() only detected a 1M window via the env
override, the [1m] model-id marker, or observed tokens already above
200k. Large-window models whose ids carry none of these (e.g.
claude-fable-5) were misclassified as 200k windows, overstating
context usage ~5x in the compact suggestion.
Add a known-model-family substring table (claude-fable-5,
claude-mythos-5) checked after the env override and [1m] marker and
before the token-count heuristic. Env overrides still win, and unknown
model ids still fall back to the 200k default.
Closes#2461
* fix(suggest-compact): anchor known-model-family match at a token boundary
Unanchored substring matching would misclassify a hypothetical smaller
tier sharing a known family prefix (e.g. claude-fable-5-mini) as a 1M
window. Require the family id to end at a token boundary: end of id, a
delimiter, or a dated/versioned suffix (-20260115). Alphanumeric
continuations and letter suffixes no longer match.
Addresses CodeRabbit/Greptile review on #2468
- #2290 suggest-compact: honor ECC_CONTEXT_WINDOW_TOKENS / CLAUDE_CODE_AUTO_COMPACT_WINDOW
so 400k-window models (Opus 4.x) no longer report ~double context usage; add
override + isolation tests in transcript-context.test.js.
- #2282 install: bare-language syntax is legacy-only by design, but the error
now distinguishes a supported-but-wrong-mode target (gemini/codex/…) from a
genuinely unknown one and points to --profile/--modules/--skills.
- #2276 cost-report: the command + cost-tracking skill targeted a SQLite DB no
tracker writes. Repoint both at the real ~/.claude/metrics/costs.jsonl (JSONL,
estimated_cost_usd), reduce cumulative-per-session snapshots to latest-per-session,
and use node instead of sqlite3 for cross-platform support.
- #2272 gateguard: make the 'confirm no existing file' checklist item
tool-agnostic (Glob/Grep or find/grep via Bash) so hosts without a Glob tool
don't get a dead tool call.
Full suite 2839/2839; lint green.
- suggest-compact hook now reads the latest usage record from the session
transcript and suggests /compact at a window-scaled token threshold
(160k/200k window, 250k/1M window; COMPACT_CONTEXT_THRESHOLD and
COMPACT_CONTEXT_INTERVAL overridable), re-firing per 60k-token growth
bucket; tool-call count stays as the secondary signal (#2155)
- Codex repo marketplace now points at ./plugins/ecc instead of ./ — Codex
never discovers plugins whose local marketplace source.path is the
marketplace root (verified on Codex CLI 0.137.0); plugins/ecc is a thin
folder referencing root skills/.mcp.json per maintainer direction on
#2097; docs flag plugin mode as experimental with the upstream blocker
openai/codex#26037 linked (#2128)
- README badges for installs/stars/forks now use shields endpoint badges
backed by api.ecc.tools (live install count 3,712 vs the stale static
150), which also eliminates shields' 'Unable to select next GitHub token
from pool' render in the stars badge
