Skill 3.9.1

• Codex loads the plugin design hook again. The plugin-packaged hook manifest carried a top-level description field that Codex's strict hook parser rejected, so the post-edit design check failed to register. That field is gone from the plugin artifact, and the hook now loads cleanly on Codex while staying identical for Claude Code.

Skill 3.9.0

• Decorative grid backgrounds are now a named tell. Impeccable refuses the two-axis CSS grid overlay built from hairline gradient lines and a repeating background-size, the pattern Codex reaches for on almost any empty surface. Actual canvases, maps, blueprints, and measurement tools still get their grid; everything else gets real product structure or a plain surface.

• /impeccable bolder stays inside your design system. When a project has a DESIGN.md, tokens, or established component styles, a bolder pass now makes the existing language more decisive through hierarchy, proportion, density, and copy instead of inventing new colors, gradients, or effects. If the system genuinely cannot express the direction, it names the exact additions and asks before expanding.

• Critique holds its independence on more harnesses. On harnesses other than Claude and Codex, the critique pass now runs in its own sub-agent more often, so the review reads the design with fresh eyes instead of inheriting the editing context that produced it.

• Bundled helpers run under strict-permission harnesses. The skill's bundled Node helpers now execute on harnesses that lock permissions down, so setup and detection work without extra approval prompts.

• Codex hook manifest fixed. Corrected the Codex hook manifest schema so the post-edit design check registers cleanly.

CLI 3.2.0

• New rule: Codex grid-line backgrounds. The detector flags the two-axis grid overlay drawn from hairline gradients plus a repeating background-size. It is a provider tell, so it stays off until you pass --gpt, and it counts only hairline gradients inside the background so a stray mask-image line does not trip it. Brings the deterministic rule set to 45.

• First install preserves an external skills symlink. Installing into a project whose ~/.claude/skills points at an external directory no longer overwrites that symlink on the first install, so shared skill setups stay intact.

Skill 3.8.0

• Design hooks for GitHub Copilot. Installing the skill adds a .github/hooks/impeccable.json hook that runs the detector after Copilot edits a UI file and feeds the findings back as a focused design reminder. It covers both the Copilot CLI and the cloud agent, and recognizes every edit path Copilot uses, including apply_patch.

• Monorepo-aware context. Open the repo root and Impeccable resolves PRODUCT.md and DESIGN.md per app: each child app uses its own context files and falls back to the root files for anything it does not define. /impeccable live detects multiple apps, asks which one to work on, and then runs and stores live state inside that app.

CLI 3.1.0

• Inline ignore comments. Waive a detector finding with an in-file comment that travels with the file, for exported or standalone documents where .impeccable/config.json is not present. impeccable-disable <rule> covers the whole file; impeccable-disable-line and impeccable-disable-next-line scope to one line. The marker works in any comment syntax, takes an optional reason, and is bypassed with --no-inline-ignores.

• Clearer errors on unknown commands. An unrecognized subcommand now fails loudly with a usage hint instead of silently doing nothing.

Extension 1.2.1

• The toolbar badge count matches the popup and panel. The browser-action badge counted flagged elements while the popup and DevTools panel counted anti-pattern findings, so the same scan showed two numbers (for example 21 vs 34). One element can carry several findings; the badge now counts findings too, so every surface agrees. Reported in #262.

• Local file scans report why they fail. Scanning a file:// page with file-URL access off used to leave the popup stuck on "Scanning…" forever. The popup now shows the real reason, with a permission hint for local files, and clears it on the next scan. Reported in #258.

• Popup matches the Kinpaku design system. The toolbar popup picks up the canonical carved-tile mark and light/dark theming that follows your system preference. Reported in #260.

CLI 3.0.3

• Existing installs now pick up script-only skill fixes. impeccable update compares the complete bundled skill tree instead of just SKILL.md, so fixes in bundled scripts are detected. Running impeccable install on an already-installed project also refreshes stale skill files instead of stopping at "already installed."

• Codex installs report the skill version. The .agents and .codex builds now include the same version frontmatter as the other harnesses, so check/update output can show the installed skill version consistently.

Skill 3.7.1

• /impeccable critique works again. The bundled detector was missing a config module it needed and crashed on startup. The build now ships that file with the skill, so critique and other detector-backed commands run cleanly.

Skill 3.7.0

• Design-aware hook detections. When a project has DESIGN.md, hooks and impeccable detect load the local design system and flag font, color, and radius drift against the documented palette, typography stacks, rounded scale, and sidecar tonal ramps.

• Ignores now work across hooks and the CLI. Detector exceptions moved into shared config, and impeccable ignores can list, add, and remove rule, file, and value ignores without hand-editing JSON.

• Docs cover the full project context path. New reference pages explain hooks, the detector, configuration, and Design Context, including how PRODUCT.md, DESIGN.md, and .impeccable/design.json are loaded and kept current.

• Docs code blocks now use the Impeccable palette. Shiki syntax highlighting uses design-system colors in both light and dark mode, with contrast tests so examples stay readable and do not trigger design-system color drift.

CLI 3.0.2

• impeccable detect now understands your design system. When a project has DESIGN.md, CLI scans load the same context as hooks and flag font, color, and radius drift against documented typography, palette, rounded scale, and sidecar tonal ramps. Pass --no-design-system when you want the global detector only.

• Ignore management is now a first-class CLI workflow. impeccable ignores can list, add, and remove rule, file, and value exceptions in the shared detector config, so teams no longer have to hand-edit .impeccable/config.json. Hooks and manual CLI scans honor the same exceptions.

• Install no longer fails silently on newer Node. On Node v24.16.0 and v26.1.0+, impeccable install could print "Downloading impeccable skills...", exit 0, and write nothing. ZIP extraction now uses pure-JS fflate, avoiding the destroyed-stream stall behind nodejs/node#63487 while preserving the Windows install fix. Reported by @kenryu42 in #250.
