vigiles: Skill for Claude Code

.claude/skills/verify-docs-findable/SKILL.md

verify-docs-findable is a skill for Claude Code from zernie/vigiles. It costs 131 tokens per session (1,316 once invoked), scanned A, original, MIT.

A documentation audit that checks whether a new reader can find answers using only a repository’s documentation. Fresh agents try realistic questions and record dead ends, source-code fallbacks, and contradictions.

In plain words
What is it for?
Use it after writing or reorganizing documentation to test navigation, answerability, conflicting guidance, and the path from the index to key answers.
Why use it?
A document can be complete yet difficult to find or use. This audit reveals when readers must search through too many pages or inspect code to answer basic questions.

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

verify-docs-findable 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 7d 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.

verify-docs-findable — cold-read the docs with fresh eyes

The insight this operationalizes: complete ≠ findable. An index that lists every doc (and even passes a "every doc is indexed" check) can still make a reader take 5 hops and fall back to source code to answer a basic question. The only honest test is to give the question to someone who has never seen the repo and watch how far they get from the docs alone. A fresh cheap agent is that someone.

Why HAIKU, and why "docs only"

  • Haiku (a small, cheap model), fresh (no session context). The point is a naive cold reader, NOT a clever one. A strong model with your context will grep the source, reason around gaps, and hide the doc problem. Haiku, told to use only the docs, exposes it.
  • "Use ONLY the docs, start at the index." The moment a verifier has to open source code to answer, the docs have failed — that's the signal. Steps-from-index is the metric.

Procedure

1. Get the questions (3–8)

Test the recurring, load-bearing, and mis-stated questions — the ones that actually cost time. Sources, in order:

  • What the user (or you) just got confused about this session — the highest-signal source.
  • The "canonical answers" the docs claim to provide (a docs corpus usually has ~5–8 facts it exists to convey; test those).
  • If none given: ask the user for the questions, or infer them from the corpus's top-level topics. Don't invent trivia — test what a real contributor needs.

Phrase each as a real question a reader would ask, not a doc title.

2. Spawn one fresh Haiku verifier per question (in parallel)

Use the Agent tool with model: "haiku", run_in_background: true, one per question. Give each the SAME strict template (fill in <QUESTION>):

You are a fresh engineer opening <repo path> for the first time. Answer using ONLY the repo's docs — START at the index (<the index file(s)>) and follow pointers; prefer docs over reading source code. QUESTION: <QUESTION> REPORT: (a) your answer; (b) the exact file(s) where you found it; (c) how many steps from the index (did a pointer take you straight there, or did you dig?); (d) clear/unambiguous or scattered/confusing? (e) did you have to read source code because the docs didn't say? Be honest — this tests whether the docs make this findable.

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.
