The review gate can create long-running loops that drain usage limits quickly. This adds two new setup flags to control how often it fires: - --review-gate-max <n|off>: cap stop-gate reviews per session - --review-gate-cooldown <minutes|off>: minimum interval between reviews When a limit is hit, the gate is skipped (session allowed to end) and a note is logged. Manual /codex:review still works at any time. Co-Authored-By: yupoet <yupoet@users.noreply.github.com>
- Only count completed jobs toward session limit (not running/queued) - Require integer for --review-gate-cooldown (no fractional minutes) - Remove unused DEFAULT_* constants, inline null fallback - Add comment documenting sorted-input assumption on findLastStopReviewTime - Add 8 unit tests for checkThrottleLimits logic Co-Authored-By: yupoet <yupoet@users.noreply.github.com>

Add --review-gate-max and --review-gate-cooldown flags to /opencode:setup so users can bound the review gate's spend: /opencode:setup --review-gate-max 5 /opencode:setup --review-gate-cooldown 10 /opencode:setup --review-gate-max off The stop hook now loads state before touching stdin, checks reviewGateMaxPerSession and reviewGateCooldownMinutes against the current session's reviewGateUsage entry, and allows the stop without running OpenCode when a limit would be exceeded. Usage entries older than 7 days are pruned on each successful run so state.json doesn't grow unbounded. renderSetup surfaces the configured limits. Closes #48. Port of openai/codex-plugin-cc#20.

* fix: quote $ARGUMENTS in cancel/result/status commands Unquoted $ARGUMENTS allows shell splitting on user-supplied job IDs containing metacharacters. Wrap in double quotes to match review.md and adversarial-review.md. Closes #38. Port of openai/codex-plugin-cc#168. * fix: declare model: sonnet in opencode-rescue agent frontmatter Without a model declaration the agent tier was unpredictable. The rescue subagent is a thin forwarder that invokes the companion via a single Bash call and applies trivial routing logic — sonnet is sufficient and gives users a cost guarantee. Closes #39. Port of openai/codex-plugin-cc#169. * fix: scope /opencode:cancel default to current Claude session Without ref, resolveCancelableJob now filters running jobs by sessionId so a cancel in session A cannot kill jobs in session B. Explicit ref still searches all sessions — naming a job counts as intent. Closes #45. Port of openai/codex-plugin-cc#84. * fix: enforce hard wall-clock timeout on runTrackedJob Wrap the runner with Promise.race against a 30-minute default timeout. On expiry the job transitions to failed/phase:failed so zombie 'running' rows can't accumulate when a runner hangs. OPENCODE_COMPANION_JOB_TIMEOUT_MS overrides the default. Closes #41. Port of openai/codex-plugin-cc#184. * fix: reconcile dead-PID jobs on every status read Adds isProcessAlive helper and reconcileIfDead / reconcileAllJobs / markDeadPidJobFailed in job-control. buildStatusSnapshot and the handleResult/handleCancel paths now probe kill(pid, 0) on any active-state job and rewrite dead ones to failed before consuming the list. A single /opencode:status / result / cancel surfaces stuck workers without waiting for SessionEnd. markDeadPidJobFailed is race-safe: it re-reads state and refuses to downgrade terminal states or rewrite when the pid has changed. Closes #42. Port of openai/codex-plugin-cc#176 + dead-PID parts of #184. * fix: avoid embedding large diffs in review prompts Classify review scope before building the prompt. When the diff exceeds ~5 files or ~256 KB, fall back to a lightweight context (status, changed-files, diff_stat) and tell OpenCode to inspect the diff itself via read-only git commands. Prevents HTTP 400 / shallow findings on moderate-to-large changesets. Adversarial template grows a {{REVIEW_COLLECTION_GUIDANCE}} slot. Thresholds overridable via opts.maxInlineDiffFiles/Bytes. Closes #40. Port of openai/codex-plugin-cc#179. * fix: respect \$SHELL on Windows when spawning child processes Add platformShellOption() helper that picks false on POSIX, and \$SHELL || true on win32 so Git Bash users get their shell while cmd fallback still resolves .cmd/.bat shims. Apply to runCommand, spawnDetached, resolveOpencodeBinary, getOpencodeVersion, and the ensureServer spawn of 'opencode serve'. Uses 'where' instead of 'which' on win32, and parses the first line of its CRLF-separated output. Closes #46. Port of openai/codex-plugin-cc#178. * fix: migrate tmpdir state to CLAUDE_PLUGIN_DATA + fix /tmp literal The fallback path was hard-coded to '/tmp' — broken on Windows. Use os.tmpdir() so Windows and other platforms get a real tmp path. Additionally: when CLAUDE_PLUGIN_DATA is set on a later call but state was previously written to the tmpdir fallback, copy it into the plugin-data dir and rewrite absolute path references inside state.json and jobs/*.json so logFile pointers don't dangle. Prevents job history from being silently dropped when commands run under different env contexts within one Claude session. Closes #47. Port of openai/codex-plugin-cc#125. * feat: pass last review findings to rescue automatically After a successful /opencode:review or /opencode:adversarial-review, save the rendered output to ~/.opencode-companion/last-review-<hash>.md (per repo, SHA-256 of workspace path). Add a new 'last-review' subcommand that reports availability or streams the content. rescue.md now checks for a saved review when invoked without task text and asks via AskUserQuestion whether to fix the prior findings or describe a new task. The save is best-effort — a failed persistence never fails the review itself. Closes #44. Port of openai/codex-plugin-cc#129 (simplified: logic lives in the companion script rather than an inline node -e one-liner). * feat: throttle controls for stop-time review gate Add --review-gate-max and --review-gate-cooldown flags to /opencode:setup so users can bound the review gate's spend: /opencode:setup --review-gate-max 5 /opencode:setup --review-gate-cooldown 10 /opencode:setup --review-gate-max off The stop hook now loads state before touching stdin, checks reviewGateMaxPerSession and reviewGateCooldownMinutes against the current session's reviewGateUsage entry, and allows the stop without running OpenCode when a limit would be exceeded. Usage entries older than 7 days are pruned on each successful run so state.json doesn't grow unbounded. renderSetup surfaces the configured limits. Closes #48. Port of openai/codex-plugin-cc#20. * feat: --worktree flag for isolated write-capable rescue tasks Add a disposable-git-worktree mode so /opencode:rescue --write --worktree runs OpenCode inside .worktrees/opencode-<ts> on a fresh opencode/<ts> branch instead of editing the working tree in place. Useful for exploratory runs, parallel rescues, and running against a dirty tree. Pieces: - lib/git.mjs: createWorktree / removeWorktree / deleteWorktreeBranch / getWorktreeDiff / applyWorktreePatch. Adds .worktrees/ to .git/info/exclude on first use so the dir never shows in status. - lib/worktree.mjs: session wrapper — createWorktreeSession, diffWorktreeSession, cleanupWorktreeSession (keep applies patch back, discard just removes). - opencode-companion.mjs: handleTask threads --worktree + swaps cwd + stores session data on the job record + renders a keep/discard footer. New worktree-cleanup subcommand reads the stored session and runs the keep or discard path. - agents/opencode-rescue.md, commands/rescue.md, skills/opencode-runtime: propagate --worktree through the forwarding layer. - tests/worktree.test.mjs: create, diff, keep-applies, discard, no-change no-op. Closes #43. Port of openai/codex-plugin-cc#137. * fix: address pr51 review findings * fix: keep tracked job timeout referenced * fix: address pr51 review conversations * fix: add exclusive file lock to updateState for concurrency safety updateState's read-modify-write cycle was not protected against concurrent companion processes (background worker + status/cancel handler), which could silently lose each other's writes. Acquire an exclusive lock file (state.json.lock via O_EXCL) before reading, hold it through mutation and write, release in finally. Stale locks older than 30s are evicted. Blocks up to 5s with retry. Closes the pre-existing concurrency race amplified by PR #51's dead-PID reconciliation (which adds upsertJob calls on every status read). * fix: address brownfield discovery bugs Critical/high fixes: - BUG-1: saveLastReview use copyFileSync+unlinkSync instead of renameSync (fixes Windows compatibility issue where rename fails if target exists) - BUG-2: handleTask worktree leak - wrap in try/finally to guarantee cleanup - BUG-3: State migration race - add fallback directory lock during migration - BUG-4/13: handleTaskWorker missing signal handlers for graceful shutdown Medium fixes: - BUG-5: releaseStateLock now fsyncs directory after lock removal - BUG-11: Error from getConfiguredProviders now logged instead of swallowed Low fixes: - BUG-6: PR number validation now rejects negative values - BUG-7: getBundledConfigDir checks directory exists before returning - BUG-8: tailLines now properly filters empty lines after split - BUG-9: resolveReviewAgent always returns tools property (undefined if not used) - BUG-10: Diff retrieval failure now logs warning instead of silent swallow - BUG-12: resolveOpencodeBinary now handles spawn errors properly Additional pre-existing work included: - safe-command.mjs wrapper for secure command execution - Command documentation updates - Test improvements * fix: polish pr51 follow-up fixes * fix: address Copilot PR#51 review comments Four findings, all valid: C1 (prompts.mjs, git.mjs, process.mjs) — buildReviewPrompt materialized the full diff string before checking thresholds. For huge diffs the git/gh subprocess could OOM the companion before the size check ran. Fix: runCommand gains maxOutputBytes, killing the child and reporting overflowed once the cap is exceeded. getDiff and getPrDiff thread maxBytes through. buildReviewPrompt now bounds the read at maxBytes+1 and treats overflow as over-byte-limit without ever materializing the rest. C2 (git.mjs) — getDiffByteSize had a docstring claiming it avoided streaming the full contents, but the implementation did exactly that. It was also dead code (zero callers). Removed. C3 (tests/state-lock.test.mjs) — the test injected path.resolve(...) into a generated ESM import specifier. On Windows that path contains backslashes and a drive letter, producing an invalid module specifier. Fix: pathToFileURL(...).href for the injected specifier. C4 (tests/dead-pid-reconcile.test.mjs) — beforeEach mutated the object returned by loadState() without saving it back, leaving on-disk state from earlier tests intact. Fix: saveState(workspace, { config:{}, jobs:[] }). Adds coverage: - tests/process.test.mjs: runCommand overflow path and non-overflow path. - tests/review-prompt-size.test.mjs: bounds-huge-diff end-to-end test that writes a 50k-byte file and asserts fewer than 10k 'x' chars land in the prompt. All 167 tests pass. * fix: keep reading fallback state while migrate lock is held Addresses a Codex P1 on PR#51: when another migrator holds \`primaryDir.migrate.lock\`, migrateTmpdirStateIfNeeded waits up to 2s and then returns without copying anything. Before this fix, stateRoot still returned primaryDir — but primary/state.json didn't exist yet, so loadState returned an empty state and the next upsertJob created primary/state.json with only the new entry, orphaning every seeded fallback job. Fix: after a migration attempt, if primary/state.json is absent and fallback/state.json is present, stateRoot returns the fallback dir. Reads see real data, writes land in fallback, and a later migration retry can pick them up cleanly. Adds a regression test that pre-creates the migrate lock, seeds fallback with a job, switches to CLAUDE_PLUGIN_DATA, and verifies that stateRoot falls back, loadState sees the seeded job, and a subsequent write preserves both the seeded and the in-flight rows. The symlink-refusal test had to be updated because it was reusing stateRoot to name the "primary" dir — with the new fallback guard, that call now returns fallbackDir on failed migration. The test now computes the expected primary path directly.
