The Bun shipped with Cloudflare Pages doesn't dedupe shared CSS chunks
across HTML entrypoints — each entry tries to emit its own copy. With
chunk: '[name]-[hash].[ext]', three sub-pages all named index.html
(skills/, tutorials/, anti-patterns/) plus shared CSS content end up
producing chunks with identical name+hash and the build aborts on
'Multiple files share the same output path'.
Including [dir] in the chunk and asset templates scopes each chunk to
its entry's source directory, so the per-entry copies land in unique
paths even when dedupe is off. Local Bun (1.3.x) still emits a single
shared chunk because [dir] is only used when there are multiple chunk
candidates.

Cloudflare Pages ships an older Bun than the one used locally. That
version emits shared CSS chunks via the default 'chunk-[hash]' naming
template, but the [hash] token isn't always populated when the chunk
is shared across multiple HTML entrypoints — every sub-page that
imports sub-pages.css ends up wanting the same './chunk-' filename
and the build aborts with 'Multiple files share the same output path'.
Pin the chunk and asset naming explicitly so [hash] is always present
regardless of Bun version.

When Bun.build aggregates resolution failures, the thrown error keeps the
real causes on error.errors (an array). The previous handler only printed
error.message and error.stack, both of which are generic / undefined for
this kind of failure, so CI logs read as 'Bundle failed / undefined' with
no clue what was unresolved. Walk error.errors first so the actual file +
import that failed shows up in CI output.

Recognize "DO NOT" / "DO" lines (with optional colon) inside <rules>
and <absolute_bans> blocks, and make skillGuideline substring matching
case-insensitive so the validator handles the new XML-structured
SKILL.md without rejecting the refactored prose.

Builds on the /skills overview landing. Every skill detail page now lives
inside the same sticky-sidebar shell, with the active skill marked via
aria-current and pulled out of the list with a 2px accent border.
- scripts/build-sub-pages.js: detail pages now wrap the .skill-detail
body in wrapInDocsLayout() and pass currentSkillId into the sidebar
renderer so the active row is marked
- public/css/sub-pages.css sidebar pass:
- Narrow from 260px to 200px (was way too wide for the content)
- Drop the redundant "Skills" label at the top (it was visually
competing with the category titles); keep the node for a11y via
visually-hidden styling
- Group titles shrink to 0.625rem mono uppercase in --color-ash so
they read as quiet signposts, not headings
- Tighten item line-height to 1.5 and vertical padding to 3px
- Replace the box-shadow inset accent with a border-left accent on
the active item, leaving it visually pulled left
- Simplify .skill-detail sizing so it works inside .skills-main
without its own max-width / padding
- Ban em dashes in user-facing copy everywhere:
- Rewrite 9 copy lines in index.html, 2 title tags in gallery.html,
inline category descriptions, the /skills overview lede + how-to,
two skills-generator comments, one aria-label, and the page titles
for Skills and skill detail pages
- New validateNoEmDashes step in scripts/build.js scans content/site,
public/*.html, and the sub-page generator sources. Build fails on
any — or — in user-facing copy. Uses commas, colons, periods,
or parentheses instead
Build green: all 26 HTML entrypoints bundle cleanly, all four hand-authored
pages retain the shared site header, anti-pattern rules still match
SKILL.md, zero em dashes.
Ships the first new sub-page section. Every user-invocable skill now has
its own page at /skills/{id}, with the canonical SKILL.md body rendered
via marked. The index at /skills lists all 21 skills grouped by category.
Editorial wrappers are opt-in: if content/site/skills/{id}.md exists, it
renders above the canonical body (with a "The skill itself" divider).
All 21 pages currently ship with the auto-rendered body only; hand-written
wrappers land in the next few commits.
- scripts/lib/sub-pages-data.js: builds the data model. Reuses
readSourceFiles() from lib/utils.js for skill content; parses the
ANTIPATTERNS array out of src/detect-antipatterns.mjs; reads optional
editorial wrappers from content/site/skills/*.md; validates that every
user-invocable skill has a category entry (build fails loudly if not).
- scripts/build-sub-pages.js: orchestrator. Writes generated HTML into
public/skills/*.html (gitignored). Called from both scripts/build.js
(before buildStaticSite) and server/index.js (at module load) so dev
and prod share the same generation code path.
- scripts/lib/render-page.js: new assetDepth parameter so generated
pages one level deep under public/ use relative paths (../favicon.svg,
../css/sub-pages.css) that Bun's HTML loader can resolve on disk.
- scripts/build.js: pass generated files into Bun.build entrypoints;
post-process to flatten build/public/* → build/* (Bun preserves the
public/ prefix when entrypoints span multiple depths).
- server/index.js: generateSubPages() runs at module load; new routes
/skills, /skills/:id, /anti-patterns, /tutorials, /tutorials/:slug
serve the pre-generated files via Bun.file().
- public/css/sub-pages.css: adds sub-page layout shell, skills index
grouped-list styling, skill detail header/meta chips/divider, collapsed
<details> reference sections, and a .prose block for rendered markdown
with editorial typography, code blocks, and inline code.
Verified: bun run build produces 26 HTML files (4 hand-authored + 22
generated), all flat under build/. Dev server returns 200 on /skills,
/skills/polish, /skills/impeccable, /skills/critique. Tests pass.
Every hand-authored HTML page now carries the same sticky top nav:
Home / Skills / Anti-Patterns / Tutorials / Gallery / GitHub. The three
future sections (skills, anti-patterns, tutorials) will land behind
these links in subsequent commits.
- Add <header class="site-header"> with a <!-- site-header v1 --> marker
to index, cheatsheet, gallery, privacy
- Each page links public/css/sub-pages.css so it picks up the shared
header styling (sticky, backdrop blur, accent-underlined current item)
- Gallery: drop the inline .site-header/.header-brand/.header-nav
definitions that predate the shared component (class names conflicted)
- Cheatsheet: restructure the page title into .cheatsheet-page-header
so it doesn't collide with the new <header class="site-header">; move
the page container max-width/padding off <body> onto .cheatsheet-page-header,
main, and footer so the shared sticky header spans the full viewport
- Privacy: full styling refresh using sub-pages.css tokens + a small
inline block for the page body typography
- Add a validateSiteHeader step to scripts/build.js that fails the build
if any of the four pages drops the marker
- Add /privacy route to server/index.js so extensionless URLs work
All four built pages pass the marker check; dev server serves all four
with 200 and the shared header.
Tailwind was wired into the build but the project didn't actually use it:
no @tailwind/@theme/@apply directives in source CSS, no utility classes
in any HTML or JS, no tailwindcss dependency in package.json, and no
HTML page linked to the compiled styles.css output.
Bun's HTML loader already handles main.css's @import chain transparently
in both `bun run dev` and `bun run build`. Removing the Tailwind step:
- Deletes buildTailwindCSS() from scripts/build.js (and the now-unused
execSync import)
- Removes public/css/styles.css (dead compiled output that nothing read)
- Updates CLAUDE.md to drop the "must rebuild Tailwind after CSS edits"
instruction
Verified: `bun run build` produces the same 104 KB CSS chunk linked from
index.html via Bun's HTML loader. No more rebuild step after CSS edits.
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.

Build system now computes authoritative counts from source (22 commands,
24 detection rules) and warns about mismatches in HTML, README, plugin
configs. Generates public/js/generated/counts.js for frontend use.
Fixed 15 stale references across index.html, cheatsheet.html, README.md,
NOTICE.md, AGENTS.md, plugin.json, and marketplace.json. Changed all
"20 commands" to "22", "25 rules" to "24". Fixed v1.6.0 changelog date
(was March 24, after v2.0.0's March 20; now March 18).
Changelog entries are excluded from validation since historical counts

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

persona-based testing, and structured follow-up workflow. Fixes browser detector
build to create target directory after skill sync.

Merge main (factory refactor) and adapt Trae to use the config-driven
transformer system instead of a standalone trae.js file. Two provider

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)

DRY refactor:
- detect-antipatterns-core.mjs (297 lines): shared constants (SAFE_TAGS,
OVERUSED_FONTS, GENERIC_FONTS, ANTIPATTERNS), color utilities (parseRgb,
relativeLuminance, contrastRatio, hasChroma, getHue, colorToHex,
isNeutralColor), and pure detection functions (checkBorders, checkColors,
isCardLikeFromProps).
- CLI (889 lines, was 1212): imports from core, keeps jsdom-specific
resolveBackground, page-level analyzers, regex fallback, and CLI logic.
- Browser wrapper (335 lines): template with browser-specific DOM adapters,
highlighting, scan loop. Core is injected at build time.
- build-browser-detector.js: reads core, strips exports, injects into
wrapper, writes to public/js/detect-antipatterns-browser.js (generated).
- Build step added to scripts/build.js (runs before Bun bundling).
Source of truth for detection logic is now the core module. Browser script
is generated — do not edit public/js/detect-antipatterns-browser.js directly.

- Anti-pattern detector script (source/skills/critique/scripts/detect-antipatterns.mjs):
CLI tool that scans files/dirs for UI anti-patterns via regex. Detects side-tab
accent borders and border-accent-on-rounded patterns across Tailwind, CSS, JSX.
Context-aware: skips safe elements (blockquotes, nav, inputs, code), neutral
colors, and adjusts thresholds based on border-radius co-occurrence.
- Browser visualizer (public/js/detect-antipatterns-browser.js):
Drop-in script that highlights anti-patterns directly in the browser with
labeled overlays. Two modes: "static" (regex, matches CLI) and "computed"
(getComputedStyle, catches CSS cascade). Scans both inline styles and
<style> blocks.
- Gallery of Shame (public/gallery.html):
Standalone page showcasing 11 AI anti-pattern examples with thumbnails
and links. Anti-pattern example pages updated from 1080x1080 Twitter
format to responsive layouts, labels removed, screenshots retaken at 16:10.
- Critique skill updated to run detector before manual review.
- Build system: skills now support scripts/ directories alongside reference/.
All 8 provider transformers refactored to use shared.js (DRY).
- 58 new tests covering detection logic, fixtures, CLI integration.

Bun's native CSS bundler doesn't support Tailwind v4's @theme directive.
Solution:
