- Fix path traversal regex prefix confusion in perl-security skill
- Revert v1.4.0 changelog entry (Perl not part of that release)
- Rename $a/$b to $x/$y to avoid shadowing sort globals
- Replace return undef with bare return per perlcritic rules
The Explore agent is a "Fast agent" optimized for codebase exploration,
not deep reasoning. The skill-stocktake V4 design requires holistic AI
judgment (actionability, scope fit, uniqueness, currency) which needs
the full reasoning capability of the conversation's main model.
Additionally, the Agent tool has no `model` parameter — specifying
`model: opus` was silently ignored, causing the evaluation to run on
the lightweight Explore model. This resulted in all skills receiving
"Keep" verdicts without genuine critical analysis.
Changing to `general-purpose` agent ensures evaluation runs on the
conversation's main model (e.g., Opus 4.6), enabling the holistic
judgment that V4 was designed for.
- Pin installation to specific commit hash (full SHA) to mitigate
supply-chain risk (cubic-dev-ai feedback)
- Add "When to Use", "How It Works", "Examples" sections to match
repo skill format conventions (coderabbitai feedback)
- Add review-before-update instructions for safe version upgrades
- Emphasize zero-runtime-risk: pure Markdown, no executable code
Claude Code sends tool output as `tool_response` in PostToolUse hook
payloads, but observe.sh only checked for `tool_output` and `output`.
This caused all observations to have empty output fields, making the
observer pipeline blind to tool results.
Adds `tool_response` as the primary field to check, with backward-
compatible fallback to the existing `tool_output` and `output` fields.
* 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.

* fix(continuous-learning-v2): observer background process crashes immediately
Three bugs prevent the observer from running:
1. Nested session detection: When launched from a Claude Code session,
the child process inherits CLAUDECODE env var, causing `claude` CLI
to refuse with "cannot be launched inside another session". Fix: unset
CLAUDECODE in the background process.
2. set -e kills the loop: The parent script's `set -e` is inherited by
the subshell. When `claude` exits non-zero (e.g. max turns reached),
the entire observer loop dies. Fix: `set +e` in the background process.
3. Subshell dies when parent exits: `( ... ) & disown` loses IO handles
when the parent shell exits, killing the background process. Fix: use
`nohup /bin/bash -c '...'` for full detachment, and `sleep & wait`
to allow SIGUSR1 to interrupt sleep without killing the process.
Additionally, the prompt for Haiku now includes the exact instinct file
format inline (YAML frontmatter with id/trigger/confidence/domain/source
fields), since the previous prompt referenced "the observer agent spec"
which Haiku could not actually read, resulting in instinct files that
the CLI parser could not parse.
* fix: address review feedback on observer process management
- Use `env` to pass variables to child process instead of quote-splicing,
avoiding shell injection risk from special chars in paths
- Add USR1_FIRED flag to prevent double analysis when SIGUSR1 interrupts
the sleep/wait cycle
- Track SLEEP_PID and kill it in both TERM trap and USR1 handler to
prevent orphaned sleep processes from accumulating
- Consolidate cleanup logic into a dedicated cleanup() function
* fix: guard PID file cleanup against race condition on restart
Only remove PID file in cleanup trap if it still belongs to the
current process, preventing a restarted observer from losing its
PID file when the old process exits.
- Fix MD012 trailing blank lines in commands/projects.md and commands/promote.md
- Fix MD050 strong-style in continuous-learning-v2 (escape __tests__ as inline code)
- Extract doc-file-warning hook to standalone script to fix hooks validator regex parsing
- Update session-end test to match #317 behavior (always update summary content)
- Allow shell script hooks in integration test format validation
All 992 tests passing.
