documentation-verification is a skill for Claude Code, Codex from PracticalSwan/agent-skills. It costs 38 tokens per session (963 once invoked), scanned A, original, MIT.

A final review process for technical documentation before it is merged or released. It checks whether the content is complete, accurate, linked correctly, and supported by working examples and commands.

In plain words
What is it for?
Use it to review READMEs, setup guides, configuration docs, and other documentation changes before merging or publishing them.
Why use it?
It catches missing coverage, broken links, incorrect snippets, and claims that no longer match the software.

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

documentation-verification 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 yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/doc-link-check.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Documentation Verification

Use this skill when a docs change needs evidence, not just a writing pass.

  • Leverage native parallel subagent dispatch and 200k+ context windows where available.

Activation Conditions

Use symptom -> action triggers: when one matches, apply this skill and verify with the protocol below.

  • Reviewing docs before merge or release
  • Checking README, setup, or config accuracy
  • Verifying local links, commands, and code samples
  • Confirming docs changed alongside user-facing behavior

Verification Workflow

  1. Confirm the docs cover the changed behavior.
  2. Check relative links and referenced files.
  3. Validate commands and snippets where feasible.
  4. Report missing coverage and stale claims explicitly.

Documentation Stack Reference

Inherit the shared stack from documentation-patterns: source-of-truth discovery, audience framing, structure selection, verification, and freshness checks. Keep this skill focused on final evidence checks instead of restating the full stack.

Anti-Patterns

  • Writing for the author instead of the reader: It bakes in unstated context and leaves the actual audience unsure what to do next.
  • Skipping concrete examples or commands: Abstract guidance is easy to approve and hard to apply correctly.
  • Letting links, screenshots, or versions drift: Polished formatting does not help if the instructions are no longer true.

Verification Protocol

Before claiming "skill applied successfully":

  1. Pass/fail: The Documentation Verification output identifies audience, purpose, source of truth, and freshness requirements.
  2. Pass/fail: Shared documentation-stack guidance is referenced instead of duplicating another documentation skill.
  3. Pass/fail: Claims, links, commands, examples, and screenshots are verified or explicitly marked unverified.
  4. Pressure-test scenario: Apply the skill to a doc request with a stale command, missing owner, and conflicting audience.
  5. Success metric: Zero undocumented assumptions; every reader-facing claim is sourced or scoped.

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
