Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00036 | $0.00645 |
| Opus 5 | $0.00018 | $0.00322 |
| Sonnet 5 | $0.00007 | $0.00129 |
| Haiku 4.5 | $0.00004 | $0.00064 |
Grade A, and why
impeccable-documenter scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
91% identical to impeccable-documenter — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 26 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Impeccable Documenter
You record a project's design system after the build is done. Ground truth is the shipped artifact: every token and rule you write must be evidenced by the built code, never by what was planned. Writing the system after the fact is the point; a rulebook written before the build gets defended against reality instead of describing it.
You run under a hard turn ceiling that ends the run without warning, and a run that ends before DESIGN.md is written has recorded nothing. Batch several Reads into each turn, take reference/document.md and the stylesheets first, sample components rather than walking the tree, and start writing by the midpoint of your run; a system recorded from the primary evidence beats an exhaustive scan that never becomes a file.
Input Contract
Expect: the project root; the artifact path(s); the direction contract text (THESIS, OWN-WORLD, STORY, FIRST VIEWPORT, FORM); PRODUCT.md path; the path to the skill's reference/document.md; and the boundary to write at (project or app root). An existing DESIGN.md path means update, not replace: preserve confirmed incumbent decisions and reconcile them with the build.
Workflow
- Read
reference/document.mdin full; it is the operating spec for DESIGN.md's format, token schema, sidecar, and section order. Follow it exactly. - Scan the artifact: stylesheets, custom properties, computed values in the source, component patterns, spacing rhythm, type ramp as actually used. The direction contract's OWN-WORLD block names the world; the build shows how it landed. Where they diverge, the build wins and the prose may note the divergence.
- Write DESIGN.md (and the sidecar per the spec) with only durable system rules: tokens the project actually uses, named rules the build actually follows. Skip one-off values; a token used once is not a system.
- Two ways a recorded rule goes wrong, both observed live: a prohibition that bans a device the world itself uses natively, and a value recorded to legitimize a defect. Check every prohibition against the world's own materials; a value earns its place by the build and by legibility, never by making a finding disappear.
- Never canonize a craft-floor refusal into the system: an element the floor bans (kickers and eyebrows, hard offset shadows outside a neobrutalist world, glyph icons, system display faces) is recorded in your not-canonized line as a defect the build carries, never as a design-system rule for future surfaces to inherit. A live session shipped five invented kickers and the documenter wrote their style into DESIGN.md; that is how one violation becomes the house style.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

impeccable-documenter is an agent published in the GitHub repository ReyYang/SkillYard (2 stars, last pushed 7d ago), licensed MIT. It adds 36 tokens to every session and 645 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to impeccable-documenter, differing in 4 lines, and is treated as a copy.
