Ryokan: Agent for Claude Code

.claude/agents/docs-site-drift-detector.md

docs-site-drift-detector is an agent for Claude Code from johnthreekay/Ryokan. It costs 119 tokens per session (2,105 once invoked), scanned A, original, GPL-3.0.

A documentation checker for a MkDocs website, a site generated from Markdown files, that compares statements in docs/ with the current code, settings screen, and Sonarr’s documentation.

In plain words
What is it for?
Use it when changing Markdown files in docs/, preparing a documentation pull request, or checking a suspicious statement. It does not cover CLAUDE.md files.
Why use it?
It helps catch user-facing instructions or claims that no longer match the software before documentation is published.

This is johnthreekay/Ryokan's own configuration. It tells Claude Code how to work on Ryokan 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 Ryokan configures →

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

docs-site-drift-detector scanned grade A with 1 finding 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 1mo 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- Sonarr docs: `curl -s https://raw.githubusercontent.com/Servarr/Wiki/master/sonarr/faq.md | grep -i "<term>"`, or `WebFetch`; search every `sonarr/*.md` page for absence claims.

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.
