os.tmpdir() returns /var/folders/.../T/ on macOS, not /tmp/. The skill
reference was telling the agent to cat /tmp/impeccable-live.json which
didn't exist. Moving the PID file to the project root makes it
predictable across platforms and project-scoped (multiple projects can
run independent live sessions).
Changed in: live-server.mjs, live-poll.mjs, live.md reference.
Added .impeccable-live.json to .gitignore.

1. CLI cleanup: removed live, poll, and wrap commands from bin/cli.js
and the liveCli export from detect-antipatterns.mjs. These now live
exclusively in the skill scripts (node scripts_path/live-server.mjs).
2. Deleted src/live/: server.mjs, poll.mjs, wrap.mjs, browser.js,
protocol.mjs. The source of truth is now source/skills/impeccable/
scripts/live-*.
3. Graceful server-lost handling: the browser tracks SSE reconnection
attempts (max 5). After exhausting retries, it cleans up the UI:
hides the bar, highlight, and cycler, shows a "Live server
disconnected" toast, resets state to IDLE. This handles agent
crashes, server kills, and network issues without leaving the
browser stuck in a "Generating..." state.

Two architectural changes that make the live variant mode self-contained:
1. SSE replaces WebSocket: the server now uses Server-Sent Events for
server→browser push and regular fetch POST for browser→server
events. This eliminates the ws npm dependency entirely. The live
server is now zero-dependency pure Node.js (http, crypto, fs, net).
Browser: EventSource replaces WebSocket. sendEvent() uses fetch POST.
Server: GET /events returns SSE stream, POST /events receives browser
events. All other endpoints (poll, source, health, stop) unchanged.
2. Scripts moved to source/skills/impeccable/scripts/: live-server.mjs,
live-poll.mjs, live-wrap.mjs, live-browser.js are now part of the
skill itself. Users who install the skill via npx skills get the live
mode without needing npm install impeccable separately.
The skill reference uses {{scripts_path}}/live-server.mjs etc.
The CLI (bin/cli.js) delegates to the skill scripts as a convenience.
Removed ws from package.json dependencies.
The old src/live/ files remain as the development copy. The build system
syncs source/skills/ to all harness dirs (11 providers).

Three optimizations to cut the generate loop from ~40s to ~15-20s:
1. wrap CLI helper (src/live/wrap.mjs): finds an element in source
by ID, class names, or tag+class combo, wraps it in the variant
container with original snapshot, and returns the file path + insert
line. Replaces 3-4 agent tool calls (grep + read + edit) with one.
Supports --element-id, --classes (comma-separated), --tag, --query
(fallback). Searches in priority order: ID > class combo > single
class > raw text. Auto-detects comment syntax (HTML vs JSX).
2. Batch variant writes: skill reference updated to instruct the agent
to write ALL variants in a single file edit instead of one per
variant. Saves N-1 tool call round-trips (~3-5s each).
3. Page URL in generate event: browser now includes location.pathname
so the agent can map URL to source file directly (/ = index.html,
/about = about.tsx, etc.) without grepping.
Net effect: agent flow is now 4 tool calls (wrap + edit + read-variant
+ poll-reply) instead of 8+ (grep + read + create-wrapper + N edits
+ poll-reply).

New feature: /impeccable live starts an interactive visual iteration server.
Users select elements in the browser, pick a design action (bolder, quieter,
etc.), and the agent generates HTML+CSS variants written directly to source.
The dev server's HMR hot-swaps them in, and MutationObserver progressively
reveals each variant in a cycler UI as it arrives.
Architecture:
- src/live/server.mjs: HTTP + WebSocket server with session token auth,
long-poll /poll endpoint for the agent, WebSocket for the browser
- src/live/poll.mjs: CLI client (npx impeccable poll / poll --reply)
- src/live/browser.js: element picker with keyboard nav (arrows=siblings,
shift+arrows=parent/child), action panel (12 commands, freeform input,
variant count), variant cycler with progressive reveal via MutationObserver
- src/live/protocol.mjs: shared message types and event validation
- source/skills/impeccable/reference/live.md: agent loop instructions
(inject script, poll loop, generate variants, accept/discard, cleanup)
CLI changes:
- bin/cli.js: added "poll" top-level command
- src/detect-antipatterns.mjs: liveCli() now delegates to src/live/server.mjs
- package.json: added ws dependency
Registered /impeccable live as command #22 across all standard locations.

When .claude/skills is a symlink to .agents/skills, updating both
providers wrote to the same directory twice -- the last write
(.agents) always won, making .claude content identical to .agents.
The up-to-date check also always failed because it compared
provider-specific bundle content against the wrong provider's files.
Fix: use realpathSync to detect shared directories and process each
unique real path only once with its matching bundle provider. Respects
the user's symlink setup for non-impeccable skills.
Tested: first run updates 18 skills, second run reports "up to date".
CLI bumped to v2.1.6.

- Build system now injects skills version (from plugin.json) into
every SKILL.md frontmatter as a version field
- CLI reads the version from the local impeccable SKILL.md and
displays it in check/update output
- Hash comparison normalizes the version field (so a version bump
alone doesn't trigger a full re-download)
- Removed misleading CLI version display from skills commands
CLI bumped to v2.1.5.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Skills installed via npx skills add resolve {{scripts_path}} to
.agents/skills/... while our bundle resolves it per-provider
(.claude/skills/..., .cursor/skills/..., etc). Without normalizing,
identical content always shows as different.
Also compare only one provider instead of all (they have the same
content, just different path prefixes).
CLI bumped to v2.1.4.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The hash comparison was comparing the entire local skills directory
(which includes user's custom skills) against the bundle (which only
has impeccable skills). Now only compares skills that exist in the
bundle, so custom skills don't cause a false mismatch.
CLI bumped to v2.1.3.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
CLI changes (bumped to v2.1.2, skills stay at v2.1.1):
- `npx impeccable skills check` compares local skill files against
the latest bundle and reports whether updates are available
- `npx impeccable skills update` now downloads the bundle first,
compares hashes, and skips with "up to date" if nothing changed
- Removed the local-modifications warning (was confusing for users
who installed via npx skills add)
Versioning:
- CLI (package.json), skills (plugin.json/marketplace.json), and
Chrome extension (manifest.json) are now versioned independently
- CLAUDE.md updated to document when to bump each

npx skills update has a known upstream bug (vercel-labs/skills#775)
where it can't find the lock file. Instead of trying it first and
falling back, always use our direct download which is reliable.
Also:
- Site now recommends `npx impeccable skills update` everywhere
instead of `npx skills update`
- Direct download path now re-applies prefix after updating
- Runs cleanup after download to strip deprecated stubs

npx skills update has a known bug where it can't find the lock file
(vercel-labs/skills#775). Our direct download fallback is the primary
working path, so the message should not sound like an error.

- Delete source/skills/ directories for deprecated skills (arrange,
normalize, onboard, extract, frontend-design, teach-impeccable).
The cleanup script handles migration; stubs are no longer needed.
- Add "npx skills update" command to the Stay Updated install section
- Rewrite FAQ update answer: lead with npx skills update, add
troubleshooting for failed updates (re-install + run /impeccable)
- Run cleanup script in `npx impeccable skills update` before
delegating to npx skills update, preventing failures from
deprecated entries in skills-lock.json
- Run cleanup script after `npx impeccable skills install` to remove
leftover files from previous versions

Merges the impeccable-detect CLI repo (pbakaus/impeccable-cli@831a6cc)
into this repo. The BSL-1.1 license that motivated the split is gone;
everything is now Apache 2.0.
- Add bin/, src/, detection tests and fixtures from CLI repo
- Merge package.json: name → "impeccable", add bin/exports/files fields
- Internal refs now read from local src/ instead of node_modules/
- Update SPDX headers, NOTICE.md, CLAUDE.md, FAQ, npm README
- Add prepack/postpack scripts for CLI-focused README on npm
- Remove terminal license labels (no longer needed)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The CLI and detection engine now live in pbakaus/impeccable-detect
(published as 'impeccable' on npm, BSL-1.1). This repo is purely
Apache 2.0: skills, prompts, website, and build system.
- Remove bin/ (CLI moved to CLI repo)
- Remove README.npm.md (moved to CLI repo)
- Remove @impeccable/detect dependency, add impeccable dependency
- Set package.json to private (no longer published to npm)
- Update all references from @impeccable/detect to impeccable
- Update CLAUDE.md, NOTICE.md, FAQ, and changelog
- Rebuild all provider skill distributions
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Replace local detection engine dependency with @impeccable/detect (BSL-1.1
licensed, github:pbakaus/impeccable-detect). The main CLI now delegates
both `detect` and `live` commands to the external package.
Update critique skill to use `npx @impeccable/detect live` instead of
python3 http.server for serving the browser detection overlay.

Major skill consolidation for v2.0:
- Rename source/skills/frontend-design/ to source/skills/impeccable/
with user-invocable: true and argument-hint: "[teach]"
- Fold teach-impeccable body into impeccable as "Teach Mode" section,
activated via /impeccable teach
- Create deprecation shims:
- frontend-design: redirects to /impeccable
- teach-impeccable: redirects to /impeccable teach
- Update all 16 skill cross-references from {{command_prefix}}frontend-design
to {{command_prefix}}impeccable and {{command_prefix}}teach-impeccable to
{{command_prefix}}impeccable teach
- Update CLI sentinel detection to use 'impeccable' (with teach-impeccable
as legacy fallback)
- Update build system readPatterns() path and EXCLUDED_FROM_SUGGESTIONS
- Update all public files (data.js, cheatsheet, index, viz, demos)
- Update all documentation (README, NOTICE, AGENTS, plugin.json)
- Update all test expectations

When skills are prefixed (e.g. i-audit), npx skills update would fail
because its lock file tracks unprefixed names. Now detects the prefix
via teach-impeccable naming, temporarily undoes the prefix (renaming
folders + reverting SKILL.md content), runs npx skills update, then
re-applies the prefix. If update fails, prefix is still restored.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
E2e tests covering: already-installed detection, prefix rename with
cross-reference updates, direct-download update fallback, and full
npx-skills install flow (skipped if npx skills unavailable).
Fixed prefix rename to handle npx-skills symlink layout: real dirs
in .agents/ are renamed and content-prefixed, then symlinks in
.claude/ are recreated to point to the renamed targets. Uses
unlinkSync (not rmSync) for symlinks to directories.
Added -y/--yes flag for non-interactive CI mode, --prefix= flag
for headless prefix selection.

Mirrors the build pipeline's prefixSkillReferences logic: when prefixing
skills after install, now also replaces /command-name invocations and
"the command-name skill" prose references throughout each SKILL.md body.

- Check for existing installation (looks for teach-impeccable skill),
bail with message unless --force is passed
- After npx skills add, prompt to prefix commands (default: i-)
with custom prefix support; renames folders and updates frontmatter
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
New `impeccable skills` CLI with three subcommands:
- `skills help`: fetches and displays all 20 commands from the API
- `skills install`: delegates to `npx skills add pbakaus/impeccable`
- `skills update`: tries `npx skills update` first; if skills aren't
managed by the skills CLI, downloads the universal bundle from
impeccable.style and overwrites provider folders directly, with
git-based modification detection and confirmation prompt
Also fixes npm metadata: homepage -> impeccable.style, license -> Apache-2.0
