Biggest change in a while. Users previously had 18 standalone skill
entries cluttering their /menu; now they have one entry (/impeccable)
that routes to 20 specialized commands via argument dispatch. The pin
mechanism (/impeccable pin audit) restores standalone shortcuts on
demand for commands users hit all the time.
## Architecture
- Single /impeccable skill with command router section in SKILL.md
- 20 commands served via reference files under source/skills/impeccable/reference/
- /impeccable pin <command> creates a lightweight redirect shim so users
who prefer /audit, /polish, etc. can still have them
- Context gathering (teach) auto-runs on first use
- command-metadata.json is the single source of truth for command
descriptions, argument hints, and relationships
## Site rewrite
- Docs URL: /skills renamed to /docs (with /skills permanent redirects)
- Homepage hero frames Impeccable as "one skill with 20 commands"
- "Get Started" split into 50/50 install + how-to-use with editorial
numbered steps, /impeccable shown as the home command with three modes
- New /docs overview: home command hero card + dense category rows
matching the old cheatsheet density, with leads-to/pairs-with/
combines-with relationship metadata served from a shared source
- Cheatsheet merged into /docs, /cheatsheet redirects
- Magazine spread and mobile cards show /impeccable as a stacked
namespace label above the command name at full display size
- Periodic table updated with craft/teach/extract as first-class cells
- Skill detail pages generate from reference files, with an editorial
wrapper per command for tagline + body
- Tutorials and anti-patterns pages updated to use /impeccable <cmd>
## Build system
- Dead code removed (scripts/lib/transformers/shared.js)
- Build log wording fixed ("1 skill" not "1 skills (1 user-invocable)")
- generateApiData fallback branch removed (throws loudly if metadata
missing instead of silently degrading)
- Commands API includes editorial tagline alongside the long description;
UI surfaces prefer tagline for human display, description for auto-
trigger keyword matching
## Gitignore
- Added .claude/scheduled_tasks.lock, .claude/settings.local.json to
ignore list (local Claude Code state that should not be tracked).
- Harness skill directories (.claude/skills/, .agents/skills/, etc.)
remain tracked by design: npx skills reads them from this repo at
install time and they enable clean submodule use.

- 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.

The post-update-cleanup section now instructs the AI to tell the user
what's happening and why before running the script, so file deletions
don't feel unexpected.

The refactored factory.js transformer dropped script file support that
existed in the old shared.js version. Scripts were read from source
but never written to dist/, so npx skills installed skills without the
cleanup-deprecated.mjs script, causing errors on first load.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The build still generates deprecated stubs in dist/ (so the cleanup
script can redirect users), but now removes them from the repo's own
harness directories so they don't clutter the local skill list.

The skill's "don't use Inter / don't use dark / don't center" negatives
were creating new attractors (the model picks Fraunces / light / grid
instead, every time). Inline always-applicable principles into SKILL.md,
add a font selection anti-attractor procedure that forces the model to
enumerate AND reject its reflex defaults, switch high-stakes blocks to
XML structure, tighten side-tab and gradient-text bans to specific CSS
patterns, ban Syne explicitly, and strip named font/color prescriptions
from the references. Validated against the internal eval framework on
Qwen 3.6 Plus across 7 niches: Fraunces dropped from 92% to 0% on kids
reading, side-tabs from 76% to 20% on vintage moto, no theme regressions.

A new icon-tile-stack detection (the canonical AI feature-card with a
small rounded-square icon container above a heading), backed by a
two-column TDD fixture, plus a single-source-of-truth design that ties
the engine to the impeccable skill so they can no longer drift silently.
Detection
- New icon-tile-stack rule (slop): heading's previousElementSibling is
a 32–128px rounded-square element with a non-transparent background
or border, contains an svg/icon-i child, and sits above (not next to)
the heading. Excludes round avatars, wide thumbnails, side-by-side
layouts, tiny icons, and hero images.
- Two-column fixture convention: a single icon-tile-stack.html with a
flag column (4 cases) and pass column (6 cases), with snippet-text
matching used by the fixture test.
Single source of truth
- Each ANTIPATTERNS entry can now declare skillSection + skillGuideline.
18 of 25 rules carry these fields; the build's new
validateAntipatternRules() in scripts/build.js fails if any declared
skillGuideline isn't found verbatim in the right SKILL.md section.
- scripts/build-extension.js now includes the description field in
extension/detector/antipatterns.json (it was previously dropped).
- The existing count validator was promoted from warn to error so
command count drift fails the build the same way detection drift does.
Impeccable skill DON'Ts
- Added 4 new top-level DON'Ts that target real default AI behavior:
single-font, flat-type-hierarchy, all-caps-body, line-length.
- Cut 7 new DON'Ts I had drafted (tight-leading, tiny-text, wide-tracking,
justified-text, low-contrast, cramped-padding, skipped-heading) because
they teach things every model already knows from CSS/a11y basics. The
detector still catches all of them.
Stale count cleanup
- 22 commands → 21 across 17 references in HTML, README, NOTICE, AGENTS,
plugin.json, marketplace.json (left over from the validate skill removal).
- Dropped the hand-coded "212 design guidelines" marketing copy on the
homepage, which never mapped to any real count.
Sub-agent
- New private .claude/agents/anti-patterns.md captures the full TDD
recipe, schema, plug-in points, jsdom constraints, and pre-commit
checklist so future sessions can add rules end-to-end without
re-investigating the wiring.

Updates the per-provider built skill files (.agents/, .claude/, .codex/,
.cursor/, .gemini/, .kiro/, .opencode/, .pi/, .rovodev/, .trae-cn/, .trae/)
to reflect the source removal of the /validate skill: deletes the
validate/SKILL.md output across all providers, drops /validate from the
command lists in audit and critique, and updates the impeccable craft
reference.

- Rename /craft skill to /shape and make it planning-only (no code output)
- Add /impeccable craft sub-command that calls /shape, loads references,
builds with visual iteration until delightful
- Replace all " -- " (em dash substitutes) with proper punctuation across
all skill files and index.html
- Move v1.6 changelog entry to "View older releases" section

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

Reverts Codex's overly bureaucratic sub-agent delegation changes (permission
prompts, "not fully compliant" disclaimers) back to clear, practical language.
Uses RFC-style SHOULD for sub-agent delegation with named examples for both
Claude Code (Agent tool) and Codex (natural language spawning).

Replace the sliding accordion with a 3D card stack for Gallery of Shame
(bottom-right deck offset with scroll/button nav). Patterns now use clean
pill tabs with single-column Don't/Do layout in a white container.
Also scaffolds two new skills: /validate (fast visual validation after UI
changes) and /craft (guided feature design through user interview).
Fixes detection count from 25 to 24, changes badge from "Deterministic"
to "New!".

- Replace tabbed pattern viewer with animated horizontal disclosure
(inspired by jh3y/XJWNMOO): CSS Grid column transitions, hover to
expand, rotated vertical labels, icon anchored at bottom
- Don't/Do toggle in each panel (defaults to Don't)
- Gallery of Shame as 2-column thumbnail sidebar beside the disclosure
- Detection callout as horizontal strip below
- Responsive: stacks at 1060px, gallery becomes 3-col grid
- Remove all em dashes from anti-pattern text (AI slop tell)

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

Each assessment now creates its own tab and labels it ([LLM] or [Human])
so parallel sub-agents don't fight over the same page state.

Merges 54 commits from main including factory-based build system, Trae support,
improved skill descriptions, and security hardening. Consolidates the critique
skill to combine v2.0's sub-agent architecture and automated anti-pattern
detection with main's Nielsen heuristics scoring, cognitive load assessment,
persona-based testing, and structured follow-up workflow. Fixes browser detector
build to create target directory after skill sync.

Take PR's improved skill descriptions (with "Use when..." trigger
phrases) and combine with main's argument-hint format. Drop old args
blocks and deleted transformer files.
Rebuild all providers so descriptions propagate everywhere.

Skill cross-references like "Use the frontend-design skill" and
"run teach-impeccable" now use {{command_prefix}} so each provider
gets the correct invocation syntax (/ for most, $ for Codex).
Prose references to skill content ("guidelines in the frontend-design
skill") are left unchanged since they're not invocation instructions.

Fixes#67: argument-hint values starting with [ were parsed as YAML flow
sequences. Replace structured args arrays in source files with pre-formatted
argument-hint strings, and quote values starting with [ or { in
generateYamlFrontmatter().
Also consolidates 8 nearly-identical transformer files into a single
config-driven createTransformer() factory. Adding a new provider now
requires only a config object in providers.js instead of a full file.
- Replace args source frontmatter with argument-hint strings
- Add YAML quoting for values starting with [ or {
- Add quote stripping to parseFrontmatter() for round-trip support
- Create factory.js + providers.js, delete 8 individual transformers
- Replace 16 explicit build.js calls with a loop over PROVIDERS
- Consolidate 8 test files into 2 (factory + providers)

Critique was vibes-only before. Now it scores against Nielsen's 10 heuristics
(0-4 each, /40 total) so you get a number, not just feelings. Added 5 user
personas that auto-select based on the interface type — a power user and a
first-timer break different things, turns out. Cognitive load checklist catches
the "why does this screen make my brain hurt" problems.
Audit gets the same treatment: 0-4 per dimension, /20 total, P0-P3 severity
instead of the vague Critical/High/Medium/Low labels nobody agrees on.
Both now present recommendations inline — no plan file, no /next or /fix-all
commands. Just tell the AI what to fix and it does it. Simpler.
New reference files: heuristics-scoring, personas, cognitive-load.
Previously only .claude/skills/ was synced from dist after build. Now
all 8 provider directories are synced (.claude, .cursor, .gemini, .codex,
.agents, .kiro, .opencode, .pi) so each provider's output can be tested
directly in this repo.
