RTLDesignSherpa: Skill for Claude Code

.claude/skills/doc-placement/SKILL.md

doc-placement is a skill for Claude Code from sean-galloway/RTLDesignSherpa. It costs 100 tokens per session (444 once invoked), scanned A, original, MIT.

A guide to deciding where different kinds of documentation belong in a code repository. It separates internal methods, reader-facing guides, work notes, and documentation kept beside code.

In plain words
What is it for?
Use it before creating or moving documentation, especially repository guides, README files, style rules, and hardware-development instructions.
Why use it?
It prevents the same fact from being copied into multiple files and stops guides from being placed in areas meant for hardware source code. It also explains when a README should link elsewhere instead of duplicating a guide.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

doc-placement 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 10d 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.

What it actually says

doc-placement

READ FIRST: vault/handbook/INDEX.md (the handbook is the repo's memory; this skill is the signpost). Canonical: vault/handbook/authoring/doc-placement.md - the four homes, the five rules, and the case each came from.

The three that get violated most:

  • Methodology never lives in the RTL tree. A style guide, how-to, or standalone guide beside code belongs in vault/handbook/ (method) or docs/markdown/ (reader-facing). A style guide in rtl/ is always wrong.
  • A beside-code README is a LINK, not a second copy. If a dir needs a quick-start, it lives in docs/markdown/ and the README points at it.
  • One source per fact. A count/spec/port list stated in two files rots - one gets updated, the other does not. Derive it or state it once and link.

Leave alone: files the tooling READS (bin/review/REVIEWER_BRIEF.md, the raw docs/review/kimi/** critiques) are artifacts, not docs. A subsystem CLAUDE.md and an area PRD.md legitimately stay beside code.

When you find a violation: git mv (history follows), repoint referrers (including ~50 generated # Documentation: code headers), leave a link, link-check.

The handbook root is vault/handbook/INDEX.md. When you learn a durable lesson in this domain, ADD IT TO THE HANDBOOK NOTE (doc-placement.md), not to this skill.

Changes

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.
