Add a first-class OpenCode command bridge across builds, installs, updates, linked installs, and pinned shortcuts. Preserve current provider behavior while backfilling missing or drifted command files.\n\nAI assistance: contributor and maintainer work used AI tools as disclosed in the PR discussion and commits.
Grok was classified as GitHub Copilot, so the design hook skipped every
edit with no-file-path and never ran Stop. Normalize toolInput/sessionId

Impeccable now ships a Hermes-compatible bundle under dist/hermes/.hermes/skills/.
Hermes reads the Agent Skills spec as-is, so the bundle uses the four spec
frontmatter fields (name, description, version, license) plus metadata/compatibility
and drops the Claude/Codex-specific extensions Hermes would silently ignore.
The .hermes/skills/ tracked root and the regenerated pin.mjs mirrors will be
produced by .github/workflows/sync-generated-output.yml after this lands; per
AGENTS.md, generated harness churn stays out of feature PRs.
What a Hermes user gets:
- npx impeccable install --providers=hermes --scope=project writes
.hermes/skills/impeccable/ into the cwd.
- npx impeccable install --providers=hermes --scope=user honors $HERMES_HOME,
so a profile-scoped install (HERMES_HOME=~/.hermes/profiles/forge) lands in
the active profile's skills dir, not the default ~/.hermes/. Cross-home
HERMES_HOME inheritance is ignored so test isolation holds.
- /impeccable registers as a Hermes slash command and routes sub-commands via
the Commands table in the skill body, since user-invocable / argument-hint
are not honored by Hermes' skill loader.
What a Hermes user does NOT get, and why:
- No hook surface. Impeccable's PostToolUse/Stop anti-pattern detector on
Claude/Codex/Cursor/Grok/GitHub does not translate to Hermes, which has no
equivalent tool event lifecycle. The skill body still ships.
- No writeOpenAIMetadata, agentFormat, or emitHooks. Hermes has no per-skill
tool ACL, no subagent on-disk format, and no hooks.json equivalent.
Verified end-to-end with hermes-agent v0.18.2: /impeccable polish and
/impeccable critique both load reference/<command>.md and return the
documented first step. parse_frontmatter accepts the generated SKILL.md,
scan_skill_commands registers /impeccable, and the full default test suite
passes (267/267 in the critical files; 0 fail across all suites).
Emit .grok skills, agents, and PostToolUse/Stop hooks; wire the CLI
installer and downloads; fix the plugin install path to #plugin; and
document Grok in HARNESSES.md and README.

* feat: add Mistral Vibe harness support
Mistral Vibe is Mistral AI's open-source CLI coding assistant that ships an
Agent Skills system at .vibe/skills/{name}/SKILL.md with slash-command
invocation, mapping cleanly onto the existing transformer pipeline. Adds
Vibe as a 14th first-class harness:
- PROVIDER_PLACEHOLDERS entry in scripts/lib/utils.js (model, config_file
= AGENTS.md, ask_instruction, command_prefix) mirroring the Qoder shape.
- PROVIDERS entry in scripts/lib/transformers/providers.js with configDir
.vibe and frontmatterFields user-invocable, license, compatibility,
metadata, allowed-tools (Vibe docs do not document argument-hint).
- transformVibe named export in scripts/lib/transformers/index.js for
test-spy parity.
- vibe added to FILE_DOWNLOAD_PROVIDER_CONFIG_DIRS so the download
endpoint accepts /api/download/skill/vibe/* and resolves to
dist/vibe/.vibe/.
- .vibe added to PROVIDER_DIRS, PROVIDER_ALIASES, PROVIDER_DISPLAY,
PROVIDER_INPUT_ORDER, GLOBAL_HARNESS_HINTS, and the normalizeForHash
provider regex in cli/bin/commands/skills.mjs so the CLI detects
existing Vibe installs.
- docs/HARNESSES.md updated: official docs row, frontmatter support
column, directory structure row, and Last verified date bumped.
- docs/DEVELOP.md, README.md (install instructions, providers list,
Supported Tools), .github issue/PR templates, sync-generated-output
workflow, and AGENTS.md extended with Vibe.
The dynamic providers.test.js loop picks up Vibe automatically; all 160
provider tests pass including the 14 new Mistral Vibe cases. The build
regenerates dist/vibe/.vibe/skills/impeccable/ with correct frontmatter
and .vibe-substituted script paths. Generated harness output is left
unstaged per the source-first policy; the sync-generated-output workflow
(now listing .vibe) will commit it back to main after merge.

* Address review on Vibe harness support
Verified the Vibe claims against the docs and the mistralai/mistral-vibe
source, then tightened what the tables say.
- model placeholder: 'Mistral', not 'the model'. Vibe is Mistral's own
first-party CLI, so it belongs with gemini -> Gemini and codex -> GPT
rather than with the provider-agnostic harnesses. SKILL.src.md's one
use of {{model}} now renders 'Mistral is capable of extraordinary
work.' instead of a lowercase 'the model'.
- Docs links point at the skills page, not the product overview, matching
every other row in both tables.
- disable-model-invocation is No, not TBD. The field appears nowhere in
Vibe's source; unknown frontmatter keys are silently ignored.
- Split the directory row into project and global scopes the way the Pi
row already does. Vibe reads .vibe/skills/ and .agents/skills/ at the
project level and ~/.vibe/skills/ and ~/.agents/skills/ globally; the
global .agents dir was missing, and project .agents/skills/ was sitting
in the global column. Sources: vibe/core/paths/_local_config_files.py
and vibe/core/config/harness_files/_paths.py.
- Restored 'Last verified' to 2026-04-28 and dated the Vibe row on its
own. Only that row was checked, and this file warns against trusting
stale claims, so a blanket re-date made ten other rows look fresher
than they are.

* Fix Pi global install path
* Simplify Pi skills-path helpers and consolidate tests
One userProviderSkillsDir helper owns the HOME_SKILLS_DIR_OVERRIDES
lookup, read paths share existingSkillsDirs, and the five Pi install
tests collapse into two that keep the same coverage: global detection
plus the agent-path write, and project scope in a home-rooted repo.
Co-authored-by: Cursor <cursoragent@cursor.com>
* Respect requested scope when resolving Pi skills dirs
An explicit install scope now narrows providerSkillsDirCandidates to
the matching layout, so a project-scope install in a home-rooted repo
no longer matches an existing global Pi install and get swallowed by
the already-installed refresh path. Update/check flows still probe
both layouts since they have no scope. Covers the T-Rex repro in the
home-rooted regression test.
Co-authored-by: Cursor <cursoragent@cursor.com>
* Refresh every existing Pi layout on unscoped update
deduplicateProviders keeps one entry per existing layout instead of
only the first, so unscoped check/update refresh both ~/.pi/agent/skills
and ~/.pi/skills when a home-rooted repo holds copies in each. Home-dir
detection now compares realpaths, since findProjectRoot resolves
symlinks while homedir() does not.

* 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.
Co-authored-by: Cursor <cursoragent@cursor.com>
* 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 Codex hook scanning: apply_patch paths and co-located stylesheets
Parse file targets from Codex apply_patch command bodies, co-scan imported
and sibling CSS when UI components are edited, drop the git-sweep PostToolUse
group, and align Codex SessionStart manifest and trust docs with the official
hooks spec.

* Gitignore hook session cache and drop local test HTML
Hook dedup/throttle state in .impeccable/hook.cache.json is per-project
runtime data like other .impeccable/ sidecars. Remove an untracked
bad-nested-flexbox scratch page from site/public/.

* 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.

* Surface Cursor design findings via stop-hook followup
Replace dropped postToolUse additional_context with afterFileEdit recording
