.claude/skills/audience-check/SKILL.md

audience-check is a skill for Claude Code from zernie/vigiles. It costs 34 tokens per session (1,172 once invoked), scanned A, original, MIT.

A documentation review that reads a README as several different kinds of first-time users and records what each person understands, misses, or finds confusing.

In plain words
What is it for?
Use it to review a README or other starting document for specific audiences, quote confusing passages, and suggest exact improvements.
Why use it?
It exposes problems the author may overlook because they already know the project. It also checks whether linked documentation supports what the README promises.

Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter. Also seen: mentions CLAUDE.md; mentions subagents; mentions Claude Code.

This is zernie/vigiles's own configuration. It tells Claude Code how to work on vigiles itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything vigiles configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

audience-check 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.

How it starts

The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Re-read the README — or whichever front-door doc the user names — as several different readers in turn, not as the author. The author knows what every line means; a first-time reader does not. The job is to surface where a specific audience gets confused, under-served, or bounces, and to propose concrete fixes.

This is an INTERNAL dev skill (not shipped to consumers). It complements the readme-brevity and docs-quality rules: those govern length/polish; this checks whether the content actually lands for who it's for.

How to run it

  1. Read the target doc in full (default: README.md; honor a path the user gives). Also skim the docs it links to, so "the README promises depth the doc doesn't deliver" is checkable.
  2. For each persona below, do a cold read — adopt that reader's goals, vocabulary, and patience. Ask their questions, not yours.
  3. Produce the report in the format at the end. Be specific: quote the exact line, name the exact fix. Vague notes ("could be clearer") are useless.

The personas

Run all of these unless the user scopes to a subset.

1. Claude Code user (the primary audience)

Already lives in Claude Code; skimming on a laptop between tasks. Wants the WOW in the first screen and a copy-paste install in seconds.

  • Does the first screen land what vigiles does and why they'd care?
  • Is the install path (npx vigiles init, the agent prompt) above the fold and obviously runnable?
  • Does it speak their language (hooks, skills, CLAUDE.md, subagents) without over-explaining?

2. Codex user (the second-harness audience)

Uses OpenAI Codex / AGENTS.md, not Claude Code. Skeptical that this is "a Claude thing."

  • Is Codex support visible early, or buried/footnoted so they assume it's CC-only?
  • Are the examples CC-only (CLAUDE.md, claude CLI) in a way that makes a Codex user feel like a second-class citizen?
  • Would they know vigiles/codex exists and what works vs. what's a documented follow-on?

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.
