docs

A documentation synchronizer that compares the README, API documentation, changelog, and architecture-decision index with the actual code. An API contract describes how software interfaces accept requests and return responses.

In plain words
What is it for?
Use it to update feature descriptions, command tables, version information, OpenAPI or GraphQL documentation when present, changelogs, and architecture-decision records.
Why use it?
It exposes documentation that has drifted away from the code and reports gaps without making up behavior. This keeps published instructions and change records tied to what exists.

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.

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 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.

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

Dispatch the docs-engineer agent (mode: full). Sync the README (features, command tables, counts, version badge), API contract docs (OpenAPI/GraphQL if present), CHANGELOG (Keep-a-Changelog), and the ADR index against the real code surface. Document only what exists — gaps are reported, never filled with guesses. Report files updated and drift found (fixed vs still-open).

Focus: $ARGUMENTS

When finished, record telemetry for this run: printf 'brief\n' > <base>/.run-complete (where <base> is the artifacts dir resolved at the storage gate — docs/hydraia/ by default, or the external dir if chosen). The Stop hook logs this run's real token/model/sub-agent usage to the local dashboard (delta-scoped per session, so it never double-counts). Do not hand-write the numbers.

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.

docs is a command published in the GitHub repository jdanigo/hydraia (8 stars, last pushed 12d ago), licensed MIT. It adds 25 tokens to every session and 231 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
