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.

External link sanitization (22 files across EN, zh-CN, zh-TW, ja-JP, .cursor):
- Removed third-party GitHub links from skills and guides
- Replaced with inline descriptions to prevent transitive prompt injection
- Kept official org links (Anthropic, Google, Supabase, Mixedbread)
Add origin field to all skill files to track their source repository.
This enables users to identify where distributed skills originated from.
Fixesaffaan-m/everything-claude-code#246
Changes based on CodeRabbit review feedback:
1. Remove entire .cursor/ directory — it was an identical copy of the
main skills/commands/agents/rules, causing maintenance drift.
Users of Cursor can reference the canonical files directly.
2. Use explicit `is not None` checks instead of truthiness for
parsed['input'] and parsed['output']. Empty strings or empty
dicts are valid values that should be preserved.
The observe.sh script receives "pre" or "post" as $1 from the hook
config, but the Python code was looking for a "hook_type" field in
the stdin JSON. Claude Code does NOT include "hook_type" in the
JSON payload passed to hooks, so it always defaulted to "unknown",
causing all observations to be recorded as "tool_complete" —
PreToolUse events were never distinguished from PostToolUse.
Fix: capture $1 as HOOK_PHASE and pass it to Python via env var.
This also fixes TIMESTAMP export in the .cursor copy where inline
`VAR=val cmd` syntax didn't propagate to the python subprocess.
The inline environment variable syntax `TIMESTAMP="$timestamp" echo ...`
does not work correctly because:
1. The pipe creates a subshell that doesn't inherit the variable
2. The environment variable is set for echo, not for the piped python
Fixed by using `export` and separating the commands:
- export TIMESTAMP="$timestamp"
- echo "$INPUT_JSON" | python3 -c "..."
This ensures the TIMESTAMP variable is available to the python subprocess.

The observer agent creates instinct files as .md with YAML frontmatter,
but load_all_instincts() only globbed *.yaml and *.yml. Add *.md to the
glob so instinct-cli status discovers all instinct files.
- Load both .yaml and .yml files in load_all_instincts() (#216)
The *.yaml-only glob missed .yml files, causing 'No instincts found'
- Implement evolve --generate to create skill/command/agent files (#217)
Previously printed a stub message. Now generates SKILL.md, command .md,
and agent .md files from the clustering analysis into ~/.claude/homunculus/evolved/
- Add try-catch around readFileSync in validate-agents, validate-commands,
validate-skills to handle TOCTOU races and file read errors
- Add validate-hooks.js and all test suites to package.json test script
(was only running 4/5 validators and 0/4 test files)
- Fix shell variable injection in observe.sh: use os.environ instead of
interpolating $timestamp/$OBSERVATIONS_FILE into Python string literals
- Fix $? always being 0 in start-observer.sh: capture exit code before
conditional since `if !` inverts the status
- Add OLD_VERSION validation in release.sh and use pipe delimiter in sed
to avoid issues with slash-containing values
- Add jq dependency check in evaluate-session.sh before parsing config
- Sync .cursor/ copies of all modified shell scripts
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
* fix: resolve multiple reported issues (#205, #182, #188, #172, #173)
- fix(observe.sh): replace triple-quote JSON parsing with stdin pipe to
prevent ~49% parse failures on payloads with quotes/backslashes/unicode
- fix(hooks.json): correct matcher syntax to use simple tool name regexes
instead of unsupported logical expressions; move command/path filtering
into hook scripts; use exit code 2 for blocking hooks
- fix(skills): quote YAML descriptions containing colons in 3 skill files
and add missing frontmatter to 2 skill files for Codex CLI compatibility
- feat(rules): add paths: filters to all 15 language-specific rule files
so they only load when working on matching file types
- fix(agents): align model fields with CONTRIBUTING.md recommendations
(opus for planner/architect, sonnet for reviewers/workers, haiku for
doc-updater)
* ci: use AgentShield GitHub Action instead of npx
Switch from npx ecc-agentshield to uses: affaan-m/agentshield@v1
for proper GitHub Action demo and marketplace visibility.
parse_instinct_file() was appending the instinct and resetting state
when frontmatter ended (second ---), before any content lines could be
collected. This caused all content (Action, Evidence, Examples) to be
lost during import.
Fix: only set in_frontmatter=False when frontmatter ends. The existing
logic at the start of next frontmatter (or EOF) correctly appends the
instinct with its collected content.
Fixes#148
Fixes#113
The instinct commands referenced hardcoded paths that only work with
manual installation (~/.claude/skills/...). When installed as a plugin,
files are at ~/.claude/plugins/cache/.../skills/...
Changes:
- Updated instinct-status, instinct-import, evolve commands to use
${CLAUDE_PLUGIN_ROOT} with fallback to manual path
- Updated observe.sh hook documentation with both install methods
- Updated SKILL.md with plugin vs manual installation instructions
- Removed duplicate commands from skills/continuous-learning-v2/commands/
(already exist in commands/)
Users should use ${CLAUDE_PLUGIN_ROOT} in their hooks config when
installed as a plugin.
