RTLDesignSherpa: Skill for Claude Code

.claude/skills/filelists/SKILL.md

filelists is a skill for Claude Code from sean-galloway/RTLDesignSherpa. It costs 58 tokens per session (319 once invoked), scanned A, original, MIT.

A set of repository rules for organizing source files into filelists, which tell build tools what code to compile. Every hardware module must have its own filelist and be registered centrally.

In plain words
What is it for?
Use it when adding hardware modules, tests, or filelists, and when checking build-source registration before committing.
Why use it?
It prevents new modules from being omitted from builds or compiled through fragile, manually maintained source lists. It also provides a check for missing or incomplete registrations.

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

filelists 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 9d 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

filelists

READ FIRST: vault/handbook/INDEX.md (the handbook is the repo's memory; this skill is the signpost). Canonical: vault/handbook/design/filelists.md.

A new module lands with its filelist IN THE SAME COMMIT, and its area must appear in bin/filelists.toml. A module with no .f has no consumers and is indistinguishable from dead code. Consumers -f include; never hand-list another area's sources.

Check before you commit: python3 bin/filelist_registry.py --check (also --audit / --find MODULE / --resolve F / --list). Note that --check prints PASS when declared - covered - exempt is empty - read all three numbers, not the PASS. [exempt] in the registry is a debt ledger with a stated reason, not a way to land a module without a filelist.

The handbook root is vault/handbook/INDEX.md - design/, dv/, fpga/, authoring/ areas, atomic notes, wikilinked. When you learn a durable lesson in this domain, ADD IT TO THE HANDBOOK NOTE, not to this skill.

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.
