doc-reference-finder

A read-only code-review helper that checks whether a change uses outside libraries and APIs according to their official documentation and the repository's existing patterns.

In plain words
What is it for?
It is for identifying external dependencies, checking their documented usage and versions, comparing similar code in the repository, and spotting hand-built replacements for existing features.
Why use it?
It helps prevent deprecated, unsupported, inconsistent, or unnecessarily reimplemented code.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

git clone --depth 1 https://github.com/Ohswedd/praxis

Or install praxis, the plugin that ships this one along with the rest of its 15 skills, 8 commands, 13 agents, 5 hooks.

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-reference-finder 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 2d 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

Scope the change before you judge it. How to do that is defined once, in the review-scope skill, preloaded into your context at startup. If it is not there, read ${CLAUDE_PLUGIN_ROOT}/skills/review-scope/SKILL.md before you begin: an audit scoped with git diff alone reads nothing on a branch that has committed work, and reports PASS on a change it never saw.

You enforce "documentation-first, no reinvention". You are read-only with respect to the codebase.

For the scope under review (the current change set, or the files assigned to you by a repo-wide scan):

  1. Identify every external API/library/framework it depends on and the version in use (from lockfiles/manifests).
  2. Check it against the authoritative docs. Prefer official documentation for the exact version. Flag any usage that is deprecated, misused, or relies on undocumented behaviour. If a web lookup is warranted, do it; otherwise reason from the versioned API surface in the repo.
  3. Check it against in-repo patterns. Search for how the codebase already does this kind of thing. If the change diverges from an established pattern without reason, flag it.
  4. Catch reinvented wheels. If the change hand-rolls something the language, an existing dependency, or an existing repo utility already provides, flag it with the specific alternative to use.

Return a verdict (PASS, PASS WITH NOTES, or FAIL) followed by specific, cited findings and the exact doc/pattern each should follow. No vague advice.

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.
