* fix(suggest-compact): clean up old counter temp files
claude-tool-count-<sessionId> files were written into the OS temp dir
on every hook run and never removed, accumulating one orphan per
session indefinitely.
Sweep stale counter files at the top of main() before opening the
active counter. Retention is env-tunable via COMPACT_STATE_TTL_DAYS
(default 14 days); invalid values fall back to the default. The
active session's counter file is preserved unconditionally even if
its mtime is past the cutoff. Failures during the sweep are swallowed
to preserve the always-exit-0 hook contract.
Adds 7 regression tests covering the sweep, env-var validation, and
the always-exit-0 invariant under a populated temp dir.
Fixes#2156
* fix(suggest-compact): preserve counter files at the TTL cutoff boundary
The cleanup sweep used `mtimeMs > cutoffMs` to short-circuit, which
matched files whose mtime sits exactly on the cutoff boundary and
deleted them. The cleanupOldCounters docstring promises only files
*older than* retentionDays are removed; a file at age == retentionDays
is not older than retentionDays, so it must survive.
Switch the comparison to `>=` so only strictly older files fall
through to deletion. Add a regression test that pins boundary-aged
files (mtimeMs sitting just past the projected cutoff) are preserved.

* fix(hooks): scrub secrets and harden hook security
- Scrub common secret patterns (api_key, token, password, etc.) from
observation logs before persisting to JSONL (observe.sh)
- Auto-purge observation files older than 30 days (observe.sh)
- Strip embedded credentials from git remote URLs before saving to
projects.json (detect-project.sh)
- Add command prefix allowlist to runCommand — only git, node, npx,
which, where are permitted (utils.js)
- Sanitize CLAUDE_SESSION_ID in temp file paths to prevent path
traversal (suggest-compact.js)

* fix(hooks): address review feedback from CodeRabbit and Cubic
- Reject shell command-chaining operators (;|&`) in runCommand, strip
quoted sections before checking to avoid false positives (utils.js)
- Remove command string from blocked error message to avoid leaking
secrets (utils.js)
- Fix Python regex quoting: switch outer shell string from double to
single quotes so regex compiles correctly (observe.sh)
- Add optional auth scheme match (Bearer, Basic) to secret scrubber
regex (observe.sh)
- Scope auto-purge to current project dir and match only archived
files (observations-*.jsonl), not live queue (observe.sh)
- Add second fallback after session ID sanitization to prevent empty
string (suggest-compact.js)
- Preserve backward compatibility when credential stripping changes
project hash — detect and migrate legacy directories
(detect-project.sh)

* fix(hooks): block $() substitution, fix Bearer redaction, add security tests
- Add $ and \n to blocked shell metacharacters in runCommand to prevent
command substitution via $(cmd) and newline injection (utils.js)
- Make auth scheme group capturing so Bearer/Basic is preserved in
redacted output instead of being silently dropped (observe.sh)
- Add 10 unit tests covering runCommand allowlist blocking (rm, curl,
bash prefixes) and metacharacter rejection (;|&`$ chaining), plus
error message leak prevention (utils.test.js)

* fix(hooks): scrub parse-error fallback, strengthen security tests
Address remaining reviewer feedback from CodeRabbit and Cubic:
- Scrub secrets in observe.sh parse-error fallback path (was writing
raw unsanitized input to observations file)
- Remove redundant re.IGNORECASE flag ((?i) inline flag already set)
- Add inline comment documenting quote-stripping limitation trade-off
- Fix misleading test name for error-output test
- Add 5 new security tests: single-quote passthrough, mixed
quoted+unquoted metacharacters, prefix boundary (no trailing space),
npx acceptance, and newline injection
- Improve existing quoted-metacharacter test to actually exercise
quote-stripping logic

* fix(security): block $() and backtick inside quotes in runCommand
Shell evaluates $() and backticks inside double quotes, so checking
only the unquoted portion was insufficient. Now $ and ` are rejected
anywhere in the command string, while ; | & remain quote-aware.
Addresses CodeRabbit and Cubic review feedback on PR #348.

- Migrate session-end.js and evaluate-session.js from CLAUDE_TRANSCRIPT_PATH
env var to stdin JSON transcript_path (correct hook input mechanism)
- Remove duplicate main() calls that ran before stdin was read, causing
session files to be created with empty data
- Add range validation (1-10000) on COMPACT_THRESHOLD in suggest-compact.js
to prevent negative or absurdly large thresholds
- Add integration/hooks.test.js to tests/run-all.js so CI runs all 97 tests
- Update evaluate-session.sh to parse transcript_path from stdin JSON
- Update hooks.test.js to pass transcript_path via stdin instead of env var
- Sync .cursor/ copies
- Fix renameAlias() leaving orphaned newAlias key on save failure,
causing in-memory data corruption with both old and new keys present
- Add sessionPath validation to setAlias() to reject empty/null paths
- Guard getSessionById() against empty string matching all sessions
(startsWith('') is always true in JavaScript)
- Fix suggest-compact.js NaN comparison when COMPACT_THRESHOLD env var
is set to a non-numeric value — falls back to 50 instead of silently
disabling the threshold check
- Sync suggest-compact.js to .cursor/ copy
Core library fixes:
- session-manager.js: wrap all statSync calls in try-catch to prevent
TOCTOU crashes when files are deleted between readdir and stat
- session-manager.js: use birthtime||ctime fallback for Linux compat
- session-manager.js: remove redundant existsSync before readFile
- utils.js: fix findFiles TOCTOU race on statSync inside readdir loop
Hook improvements:
- Add 1MB stdin buffer limits to all PostToolUse hooks to prevent
unbounded memory growth from large payloads
- suggest-compact.js: use fd-based atomic read+write for counter file
to reduce race window between concurrent invocations
- session-end.js: log when transcript file is missing, check
replaceInFile return value for failed timestamp updates
- start-observer.sh: log claude CLI failures instead of silently
swallowing them, check observations file exists before analysis
Test fixes:
- Fix blocking hook tests to send matching input (dev server command)
and expect correct exit code 2 instead of 1
utils.js:
- Fix countInFile: enforce global flag on regex to prevent silent
under-counting (match() without /g returns only first match)
- Add 5s timeout to readStdinJson to prevent hooks hanging forever
- Handle EEXIST race condition in ensureDir
- Pre-compile regex patterns in getGitModifiedFiles to avoid N*M
compilations and catch invalid patterns before filtering
- Add JSDoc documentation to all improved functions
session-manager.js:
- Fix getSessionById triple file read: pass pre-read content to
getSessionStats instead of re-reading from disk
- Allow getSessionStats to accept content string directly
session-aliases.js:
- Wrap temp file cleanup in try/catch to prevent cascading errors
check-console-log.js:
- Refactor to use shared utils (isGitRepo, getGitModifiedFiles, log)
instead of raw execSync calls
- Add exclusion patterns for test files, config files, and scripts/
where console.log is intentional
session-end.js:
- Log count of skipped unparseable transcript lines for diagnostics
suggest-compact.js:
- Guard against NaN from corrupted counter files
package-manager.js:
- Remove dead fallbackOrder parameter (unused after #162 fix)
- Fix 16 ESLint no-unused-vars errors across hook scripts and tests
- Add eslint-disable comment for intentional control-regex in ANSI stripper
- Update session file test to use getSessionIdShort() instead of hardcoded 'default'
(reflects PR #110's project-name fallback behavior)
- Add marketing/ to .gitignore (local drafts)
- Add skill-create-output.js (terminal output formatter)
All 69 tests now pass. CI should be green.
