Rex LorenzoandGitHub 14d2641685 Fix: keep the node runtime probe clear of cmd.exe metacharacters (#458)
Volta's Windows shims exec through `cmd /C`, which re-parses the argument
list, so the `>=` inside the probe's `node -e` payload was read as output
redirection. The command died with "The filename, directory name, or volume
label syntax is incorrect" before node started, the guard read that as a
missing runtime, and the hook it exists to protect was disabled on every
PostToolUse and Stop. A user on a supported Node 24 got a one-time notice
telling them to install Node 22, then silence.

Clamping with Math.min is the same floor test in the same ES5-only syntax,
with no character cmd.exe can claim. Verified through the Volta shim on Node
24.16.0 and 22.18.0 (exit 0) and against a real Node 20.6.1 binary (exit 1),
so the floor is unchanged. Adds a regression test asserting no `<`, `>`, or
newline reaches any generated `node -e` payload.

Upstream cause: volta-cli/volta#1791.

fd9076f4f0 Enforce the engines floor in the probe instead of a capability check
The probe asked whether node could load ESM, while the notice promised a
Node 22 floor and package.json engines declares >=22.12.0. Reviewers kept
flagging the gap, and they were right to: a 14.18-to-21 runtime passed the
probe on the strength of one import while the hook and its detector bundle
are only ever exercised on the engines floor, so "can load our code" was a
weaker claim than the one being made for it.

Check the floor directly: parseInt(process.versions.node) >= 22, in
ES5-only syntax that parses on any node old enough to fail it. Probe and
notice now derive from one NODE_MAJOR_FLOOR constant, so they cannot
disagree, and the archaeology about node: scheme support and pre-15
unhandled-rejection semantics goes with the import it explained.

Add the missing contract test: every generated hook command carries the
probe, the notice appears exactly where a harness can render it (Claude
and Codex, project and plugin), and the expected floor is read from
package.json engines rather than repeated by hand.

Verified against a fake pre-22 node, no node, and a real node: one notice
then the marker holds it silent, exit 0 in every failure shape, and the
hook's own exit code still passes through on a supported runtime.

Abdul WahabandClaude Opus 5 86cdf528c5 Probe the import the hook actually uses, and fail closed on rejection
Greptile flagged that the probe does not enforce the Node 22 engines floor.
Two parts to that, and they land differently.

The real defect is narrower and worse than stated: the hook closure imports
`node:fs`, `node:os`, `node:path` and `node:url`, and the `node:` scheme needs
14.18, so a bare `import('fs')` probe passed on 12 and 13 and those runtimes
then died on the real import, which is the banner this branch exists to remove.
Probing `node:fs` closes that. The added `.catch(()=>process.exit(1))` is load
bearing rather than tidiness: before Node 15 an unhandled rejection is only a
warning and the process still exits 0, so a rejected probe would have read as a
pass on exactly the versions in question.

Not enforcing 22 is deliberate and stays. The probe asks whether this runtime
can load our code, not whether it is a supported one, so a 14.18-to-21 runtime
that works today keeps working rather than being silently switched off. The
notice names 22 because that is the version worth installing, and it only ever
reaches someone whose runtime already failed the probe, so no user is shown a
threshold that contradicts what ran.

Abdul WahabandClaude Opus 5 8397d532b9 Keep the unsupported-node notice to the harness that can render it
`systemMessage` on stdout is a Claude Code contract. The shared guard was
emitting it for Codex and Cursor too, where what a harness does with stdout
it did not ask for is unconfirmed, and a Cursor preToolUse hook printing an
unexpected JSON object is the wrong thing to guess about.

Pass the notice in per harness instead of baking it into the guard. Claude
manifests opt in; Codex and Cursor take the runtime probe alone, so an
unsupported runtime stays as quiet there as it was before the probe existed.
Giving them their own shape later is one more argument at the call site.

Abdul WahabandClaude Opus 5 0db59088ff Stop the design hook erroring on a node too old for ESM
The hook command invokes bare `node`. When that node predates ESM,
`hook.mjs` dies while it is still being parsed, before the script's own
always-exit-0 contract can run, so node exits 1 and the harness reports a
hook error on every Stop and every edit.

Probe the runtime in the command string before invoking the hook, and
route the Claude plugin manifest through the guard that already covered
the project-local manifests. On probe failure the command exits 0 and
emits a one-time `systemMessage` naming the two fixes available to the
user, since nothing written in ESM can report this condition.

Fixes #410.

Paul BakausandClaude Fable 5 eda81f0937 Release prep: skill v4.0.1
Bump plugin + marketplace to 4.0.1 and sync the regenerated provider
output: the guarded hook commands from issue #399 (a missing hook file
exits 0 instead of crashing every turn of a user-level install), the
canon standing exit, the visualize flow, the two shipped subagents, and
the interactive-spine fixes from today's live testing. Detector count
validates at 59 with undersized-ui-text.

672517f76e Add automatic design hook install and exceptions (#170)
* docs: add PRD for design detector hook integration

Plans a PostToolUse hook for Claude Code and Codex that runs the
existing design detector after every relevant file write and feeds
findings back to the agent as advisory system-reminder context. No
implementation in this commit; covers UX, technical design, build
pipeline changes, distribution, coverage tradeoffs, and rollout.

* docs: revise hook PRD with best-practices review

Folds in the P0/P1/P2 findings from an online best-practices critique
against the official Claude Code and Codex hook references plus 10+
2026 community guides and similar prior-art tools (claw-hooks,
claude-code-hooks-mastery).

Key changes:
- Exec form everywhere (Codex snippet was shell form), with Windows
  rationale.
- Default timeout dropped from 10s to 5s.
- Re-entrancy guard (CLAUDE_HOOK_DEPTH) and per-file edit counter.
- Session-scoped finding dedup promoted from open question to v1.
- Per-language inline-ignore syntax map (HTML/JSX/CSS/JS).
- Hard-skip rules for sensitive paths and generated/lock files.
- Honest framing about Claude Code lacking per-plugin hook disable.
- Honest framing about Bash-written files being invisible in v1.
- Codex Windows-not-supported call-out, feature flag note, trust ceremony detail.
- Optional NDJSON audit log via IMPECCABLE_HOOK_LOG.
- Findings cap lowered 8 → 5 with attention-budget rationale.
- Versioned envelope ([impeccable@1]) on rendered template.
- Expanded test plan, decision log, and stdin payload appendix.

* feat(hooks): ship the design detector hook for Claude Code and Codex

Implements docs/hooks-prd.md: a PostToolUse hook that runs the
impeccable design detector after every Edit/Write/MultiEdit on a UI
file and pushes findings into the agent's next-turn context as a
short system reminder. Silent on clean files. Never blocks an edit.

Why this matters: today, design slop (side-tab borders, gradient
text, purple/cyan palettes, bounce easing, etc.) only gets caught
when a human notices or someone explicitly runs /impeccable audit.
The hook closes the loop at the moment slop is written.

What ships in v1
- skill/scripts/hook.mjs: PostToolUse entry. Reads stdin, runs the
  detector in-process (no `npx impeccable` cold start), emits
  hookSpecificOutput.additionalContext when fresh findings exist.
- skill/scripts/hook-lib.mjs: extracted helpers (config, cache,
  filter, render, audit log, runHook orchestrator). 100% unit-testable.
- skill/scripts/hook-session-start.mjs: SessionStart greeting,
  gated by a project-scannable probe + 30-day throttle.
- skill/scripts/hook-admin.mjs: backs /impeccable hooks
  on/off/status/ignore-rule/ignore-file/reset.

Hardening built in
- Re-entrancy guard (IMPECCABLE_HOOK_DEPTH) so the hook can never
  recursively spawn itself.
- Hard-skip regexes for sensitive paths (.env, .pem, id_rsa,
  secrets, credentials, .git) and generated/lock/build output. These
  fire before the file is even read; cannot be turned off via config.
- Path-traversal check on the inbound file_path.
- Session-scoped dedup keyed by (session, file, rule, line) so the
  same finding never lands in context twice. Prevents the ~12.5K
  wasted tokens per chatty session called out in the PRD.
- Per-(session, file) edit counter with a one-shot suppression
  notice on the 7th edit, silent after.
- Fail-open contract: every error path returns exit 0 with no
  stdout. Optional NDJSON audit log via IMPECCABLE_HOOK_LOG.

Three kill switches (precedence high to low):
1. IMPECCABLE_HOOK_DISABLED env var (1/true/yes/on, case-insensitive)
2. .impeccable/hook.json `enabled: false`
3. /impeccable hooks off slash command (writes the JSON)

Inline ignores are language-aware. `// impeccable: ignore <rule>` for
JS/TS, `<!-- impeccable: ignore <rule> -->` for HTML/Vue/Svelte/Astro,
`{/* impeccable: ignore <rule> */}` for JSX/TSX, `/* impeccable:
ignore <rule> */` for CSS. `*` matches any rule. Directive applies
to the next non-blank line. Same shape as ESLint, Stylelint, Biome.

Build pipeline
- scripts/lib/transformers/hooks.js: per-provider hooks.json
  builders, plus the slim .codex-plugin/plugin.json manifest.
- providers.js: emitHooks: 'claude' for claude-code, emitHooks:
  'codex' for codex and agents. Codex also emits emitCodexPlugin.
- factory.js: emits hooks/hooks.json next to the skills tree.
- build.js: syncs hooks/ into harness roots and into the slim
  plugin/ subtree; writes .codex-plugin/plugin.json. Build is
  idempotent (verified: 98 staged files unchanged across two runs).

Claude Code wiring uses exec form (command + args) and the
${CLAUDE_PLUGIN_ROOT} placeholder. Matcher: Edit|Write|MultiEdit.
`if:` glob filters to UI extensions before spawning Node. PostToolUse
timeout 5s, SessionStart timeout 3s.

Codex wiring uses ${PLUGIN_ROOT} (Codex's native placeholder),
matcher Edit|Write|apply_patch, no `if:` analog (the script does the
extension filter). macOS and Linux only; hooks are disabled on
Windows in current Codex builds. The trust ceremony and feature flag
are documented in README.md.

Routing
- /impeccable hooks lives outside the 23-command router table on
  purpose: it is plumbing, not a design skill. The hidden
  routing slot is added to SKILL.md alongside pin/unpin so the LLM
  knows to dispatch it. The 23-command count and all stale-count
  validators remain happy.

Tests
- tests/hook.test.mjs: 38 unit tests covering env parsing, config
  load + defaults + malformed, cache round-trip + GC,
  ignoreRules/minSeverity/inline ignores (all four languages),
  globbing with **/*/{a,b}, render template with cap + clamp + 0-line
  prefix drop, audit log NDJSON, payload event-name parameterization,
  re-entrancy, kill switches, sensitive-path + generated-path +
  traversal skips, allowlist filter, config ignoreFiles, edit
  counter cycle including the 7th-edit notice, MultiEdit and
  apply_patch payload shapes, detector throw swallow, malformed
  stdin, missing file race.
- tests/hook-build.test.mjs: 18 integration tests covering hook
  manifest shape (matcher, timeouts, exec form, if: glob, placeholders),
  Codex differences (${PLUGIN_ROOT}, no if:, no SessionStart),
  Codex plugin manifest (no inline hooks field to avoid the
  duplicate-file error), routing across the hooksJsonFor table, and
  presence of all three committed artifacts plus the bundled detector
  the runtime relative-import path depends on.

Full suite: 175 bun tests + 186 node tests, all green.

Docs
- README.md: new "Design hook" section explaining default behavior,
  per-project / global / inline disable paths, the JSON schema knobs,
  the audit log debug flag, and the slop / a11y coverage split.
- HARNESSES.md: flips the `hooks` row for Codex from No -> Yes
  (Claude was already Yes), adds a per-harness hook-surface table
  with the manifest location and matcher each provider uses.

Open questions from the PRD intentionally deferred to v2: Bash-write
blind spot, effort-aware suppression, Stop-hook session summary,
per-rule severity, async hook mode. None block v1.

* Fix Claude Code hook: drop Edit-only if filter so Write/MultiEdit fire

Claude's if permission rule binds to one tool name, so Edit(*.{…}) never
spawned the hook on Write or MultiEdit despite the matcher listing them.
Extension filtering now lives in hook-lib on both Claude and Codex.
