feat(hooks): add context-gate — deterministic checkpoint-and-restart gate at 90% context - #3106
CarbonPyramid wants to merge 4 commits into
Conversation
Deterministic UserPromptSubmit gate: at >=90% context occupancy, inject a mandatory checkpoint protocol (clean stopping point, structured RESUME.md, one-line resume command, close session) instead of per-turn advisory stop suggestions. Escalates to immediate checkpoint at >=96%. Silent below threshold; fails open silent. Reuses transcript-context.js for measurement.

The new launcher assigns process.env.CLAUDE_PLUGIN_ROOT and mutates process.argv with splice before loading the bootstrap. This violates the repository directive to create new objects rather than mutating existing ones. The launcher must construct derived environment and argument values without process-wide mutation; this repository requirement must be satisfied before merging.

Learning: JavaScript test files under tests/ must print summary lines in the exact format `Passed: N` and `Failed: N` to their combined stdout and stderr. The `tests/run-all.js` aggregator parses these lines to include each test file's results in the repository-wide totals.

Learning: In this repository, do not flag `console.log` usage as a guideline violation in hook test files under `tests/hooks/*.test.js`. These tests intentionally use `console.log` for pass/fail output because the repo’s console-based runner (`tests/run-all.js`) is used and there is no Jest/Mocha dependency. Outside this specific hook-test path, follow the normal logging guidelines.

Learning: JavaScript tests under tests/ should emit a summary containing parseable tokens in the form `Passed: N` and `Failed: N`. The `tests/run-all.js` aggregator parses these tokens from combined stdout and stderr, so a combined line such as `Results: Passed: N, Failed: N` is sufficient; do not require separate `Passed: N` and `Failed: N` lines.

…ng, test summary tokens) - run() second arg is runner metadata from run-with-flags.js, not the environment; read controls from options.env || process.env so ECC_CONTEXT_GATE_PCT / ECC_CONTEXT_GATE_EMERGENCY_PCT work in the registered hook path (they were silently ignored before). Regression test exercises the metadata-second-arg shape against process.env. - resolvePct: require a whole decimal integer before conversion; parseInt accepted '90abc' (-> 90) and '0x1' (-> 0, silently disabling the gate) instead of falling back. - Test summary now emits the 'Passed: N' / 'Failed: N' tokens that tests/run-all.js parses; the lowercase format contributed zero to repo totals.
…ning Conflict management (the gate previously had none): - New scripts/lib/context-gate-state.js — single source of truth for gate thresholds plus isGateEnabled/isGateActive; context-gate.js now imports from it (public exports unchanged). - suggest-compact defers to the gate: both the context-size and tool-count /compact suggestions stay silent at/above the gate threshold. The gate orders checkpoint-and-restart there; suggesting the lossy /compact path in the same band was a contradictory instruction. The transcript-reading gate check on the count path only runs when a count message would fire. - ecc-context-monitor defers to the gate: the context warnings (including the critical 'ask the user / do NOT write handoff files' text, which directly contradicted the gate's checkpoint order) are suppressed inside the gate band; cost/scope/loop warnings unaffected. - Header + hooks/README.md now state the real auto-compact interaction: with auto-compact ON, compaction (~83.5% used per ecc-statusline's 16.5% buffer) precedes the 90% gate, so autoCompactEnabled:false (or a raised window) is required for the gate to be reachable — the previous 'safe with auto-compact left on' claim was wrong. Inferred-window softening (review feedback): - When the window size is inferred (unrecognized model), the gate fires as a strong recommendation instead of an order and flags the inference plus the ECC_CONTEXT_WINDOW_TOKENS override, so a possibly-wrong 200k denominator never forces a restart on a larger-window model. Known models keep the mandatory wording. Tests: inferred-softening case; gate-deference pairs for both advisory hooks; ecc-context-monitor test summary switched to the parseable 'Passed:/Failed:' tokens run-all.js requires.

CodeRabbit (test summary tokens) — fixed in 6813b4a ( Greptile #2 (inferred windows force restarts) — addressed in 03b1a80. When the window size is inferred the gate still fires (an unrecognized true-200k model at 90% is exactly the case the gate exists for) but as a strong recommendation instead of an order, explicitly flagging the inference and the Greptile #3 (launcher mutates process state) — not changed.

ECC_CONTEXT_GATE_PCT=90 and the advisory hooks’ deferral at that boundary.

- Line 121: Update resolveContextWindow to accept an environment argument and
use it for context-window configuration, then pass the injected env variable
from run instead of relying on process.env. Add a regression test covering an
options.env override for ECC_CONTEXT_WINDOW_TOKENS.

resolved transcript usage and confirmed gate activity, not just configuration,
remaining capacity, and bridge percentage. Pass the resolved usage from the

Learning: In this repository, do not flag `console.log` usage as a guideline violation in hook test files under `tests/hooks/*.test.js`. These tests intentionally use `console.log` for pass/fail output because the repo’s console-based runner (`tests/run-all.js`) is used and there is no Jest/Mocha dependency. Outside this specific hook-test path, follow the normal logging guidelines.

… injected env through window resolution Round-2 review fixes: - ecc-context-monitor no longer suppresses its context warnings on configuration + bridge percentage alone. Deference now requires CONFIRMED gate activity via the shared gateOwnsTranscript (moved from suggest-compact into lib/context-gate-state.js): transcript readable, usage resolved, occupancy at/above threshold. When the gate cannot evaluate usage (missing/unreadable transcript) it cannot fire, so the monitor's CONTEXT CRITICAL warning survives as the fallback — an 8%-remaining session is never left with no guidance. The transcript read only happens when a context warning is possible (<=35% remaining). run()-level tests encode both the fallback and suppression paths. - resolveContextWindow accepts an env argument; context-gate and suggest-compact pass their (possibly injected) env through, so an options.env ECC_CONTEXT_WINDOW_TOKENS override now reaches window resolution instead of silently falling back to process.env. Regression tests cover the injected form and the registered-path process.env form. - hooks/README.md: 'At or above the gate threshold' (deferral is inclusive at 90%), plus the fallback behavior. - New tests/lib/context-gate-state.test.js covering threshold resolution, enabled/active checks, and gateOwnsTranscript semantics. Full suite: 4748/4748.

Learning: In this repository, do not flag `console.log` usage as a guideline violation in hook test files under `tests/hooks/*.test.js`. These tests intentionally use `console.log` for pass/fail output because the repo’s console-based runner (`tests/run-all.js`) is used and there is no Jest/Mocha dependency. Outside this specific hook-test path, follow the normal logging guidelines.

Timestamp: 2026-07-16T15:23:29.177Z
Learning: In this repository, standalone JavaScript test suites under tests/lib/ follow a local runner convention: they use mutable `passed`/`failed` counters and print per-test console output. During code reviews, treat this as the expected harness style and generally avoid recommending one-off refactors to immutable counters for new/modified suites. Only request such counter refactors if the repository-wide test harness/convention is being changed.

File: tests/skills/story-lifecycle.test.js:36-36
Timestamp: 2026-08-13T23:48:47.192Z
Learning: JavaScript tests under tests/ should emit a summary containing parseable tokens in the form `Passed: N` and `Failed: N`. The `tests/run-all.js` aggregator parses these tokens from combined stdout and stderr, so a combined line such as `Results: Passed: N, Failed: N` is sufficient; do not require separate `Passed: N` and `Failed: N` lines.

Validate the complete context-window override.
Number.parseInt accepts 1e6 as 1 and 1000000junk as 1000000. The injected environment path then marks the window as non-inferred. scripts/hooks/context-gate.js can therefore issue a mandatory gate instruction from a configuration typo. Require a whole positive safe decimal integer before conversion. Add regression cases for malformed overrides.
Proposed fix
- const envWindow = Number.parseInt(environment.ECC_CONTEXT_WINDOW_TOKENS || environment.CLAUDE_CODE_AUTO_COMPACT_WINDOW || '', 10);
- if (Number.isInteger(envWindow) && envWindow > 0) {
+ const rawWindow = environment.ECC_CONTEXT_WINDOW_TOKENS || environment.CLAUDE_CODE_AUTO_COMPACT_WINDOW || '';
+ const normalizedWindow = String(rawWindow).trim();
+ const envWindow = /^\d+$/.test(normalizedWindow) ? Number(normalizedWindow) : NaN;
+ if (Number.isSafeInteger(envWindow) && envWindow > 0) {As per coding guidelines, “Never trust external data ... always validate.”

Summary
Adds
context-gate.js— ECC's firstUserPromptSubmithook — a deterministic checkpoint-and-restart gate that fires at ≥90% context-window occupancy and replaces the model's per-turn "good stopping point" narration with a single, complete end-of-session protocol.The problem this exists to kill
Once a session climbs into the upper range of the context window, the model starts padding nearly every turn with unprompted session-management narration:
As an operator deep in a long build, this is not a small annoyance:
ECC's current surface manages the mechanics around this moment but leaves the decision loop open — and in one place institutionalizes it:
ecc-context-monitor's CRITICAL message explicitly instructs the model to "ask how they want to proceed", andsuggest-compactre-reminds in buckets as context grows. Both are advisory by design. Advisory means: the question comes back every turn.The fix: take the decision away from the model entirely
suggest-compact's own header makes the key argument: auto-compact fires at arbitrary points, often mid-task, and lossy summarization at an arbitrary point is how verified facts, ruled-out hypotheses, and half-finished threads get silently mangled. This hook takes that argument to its logical end: the correct terminal action for a full window is not a lossy in-place summary and not a per-turn ask — it's a curated, auditable checkpoint on disk and a fresh session grounded on it, triggered by a deterministic threshold.Behavior:
ECC_CONTEXT_GATE_PCT): injects an order, not a suggestion — finish only the in-flight unit of work to its nearest clean stopping point (no new work streams), write a structuredRESUME.mdcheckpoint (objective; VERIFIED facts strictly separated from hypotheses; approved decisions; ruled-out approaches and why; exact next steps; pending changes), hand the operator a one-line resume command, state that the session must close. Explicitly forbidden: "want to pause?", offering alternatives, continuing past the checkpoint.ECC_CONTEXT_GATE_EMERGENCY_PCT): checkpoint immediately, mid-task if necessary, recording the interruption point.Designed to pair with
autoCompactEnabled: false(checkpoint always lands before any lossy summarization can), but safe with auto-compact left on — 90% fires well before default compaction.Relationship to existing hooks (not a duplicate)
suggest-compactpre-compact/session-startecc-context-monitorcontext-gate(this PR)Possible follow-up (separate PR): when the gate is enabled, align
ecc-context-monitor's CRITICAL context message with the gate's directive so the two never give contradictory instructions in the ≥90% band.Type
