impeccable — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited impeccable (Agent Skill) and scored it 65/100 (yellow). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 8 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
Designs and iterates production-grade frontend interfaces. Real working code, committed design choices, exceptional craft.
Before any design work or file edits:
craft without craft.md loaded means you'll skip the shape-and-confirm step the user expects.Skipping these produces generic output that ignores the project.
Two files, case-insensitive. The loader looks at the project root by default and falls back to .agents/context/ and docs/ if the root is clean. Override with IMPECCABLE_CONTEXT_DIR=path/to/dir (absolute or relative to cwd).
Load both in one call:
node .claude/skills/impeccable/scripts/load-context.mjsConsume the full JSON output. Never pipe through head, tail, grep, or jq. The output's contextDir field tells you where the files were resolved from.
If the output is already in this session's conversation history, don't re-run. Exceptions requiring a fresh load: you just ran /impeccable teach or /impeccable document (they rewrite the files), or the user manually edited one.
/impeccable live already warms context via live.mjs. If you've run live.mjs, don't also run load-context.mjs this session.
If PRODUCT.md is missing, empty, or placeholder ([TODO] markers, <200 chars): run /impeccable teach, then resume the user's original task with the fresh context. If the original task was /impeccable craft, resume into /impeccable shape before any implementation work.
If DESIGN.md is missing: nudge once per session ("Run `/impeccable document` for more on-brand output"), then proceed.
Every design task is brand (marketing, landing, campaign, long-form content, portfolio: design IS the product) or product (app UI, admin, dashboard, tool: design SERVES the product).
Identify before designing. Priority: (1) cue in the task itself ("landing page" vs "dashboard"); (2) the surface in focus (the page, file, or route being worked on); (3) register field in PRODUCT.md. First match wins.
If PRODUCT.md lacks the register field (legacy), infer it once from its "Users" and "Product Purpose" sections, then cache the inferred value for the session. Suggest the user run /impeccable teach to add the field explicitly.
Load the matching reference: reference/brand.md or reference/product.md. The shared design laws below apply to both.
Apply to every design, both registers. Match implementation complexity to the aesthetic vision: maximalism needs elaborate code, minimalism needs precision. Interpret creatively. Vary across projects; never converge on the same choices. Claude is capable of extraordinary work. Don't hold back.
#000 or #fff. Tint every neutral toward the brand hue (chroma 0.005–0.01 is enough).Dark vs. light is never a default. Not dark "because tools look cool dark." Not light "to be safe."
Before choosing, write one sentence of physical scene: who uses this, where, under what ambient light, in what mood. If the sentence doesn't force the answer, it's not concrete enough. Add detail until it does.
"Observability dashboard" does not force an answer. "SRE glancing at incident severity on a 27-inch monitor at 2am in a dim room" does. Run the sentence, not the category.
Match-and-refuse. If you're about to write any of these, rewrite the element with different structure.
border-left or border-right greater than 1px as a colored accent on cards, list items, callouts, or alerts. Never intentional. Rewrite with full borders, background tints, leading numbers/icons, or nothing.background-clip: text combined with a gradient background. Decorative, never meaningful. Use a single solid color. Emphasis via weight or size.--.If someone could look at this interface and say "AI made that" without doubt, it's failed. Cross-register failures are the absolute bans above. Register-specific failures live in each reference.

Plus two management commands: pin <command> and unpin <command>, detailed below.
Setup (context gathering, register) is already loaded by then; sub-commands don't re-invoke /impeccable.
If the first word is craft, setup still runs first, but reference/craft.md owns the rest of the flow. If setup invokes teach as a blocker, finish teach, refresh context, then resume the original command and target.
Pin creates a standalone shortcut so /<command> invokes /impeccable <command> directly. Unpin removes it. The script writes to every harness directory present in the project.
node .claude/skills/impeccable/scripts/pin.mjs <pin|unpin> <command>Valid <command> is any command from the table above. Report the script's result concisely. Confirm the new shortcut on success, relay stderr verbatim on error.
