update-docs

update-docs is a skill for Claude Code, Codex from marin-community/marin. It costs 32 tokens per session (298 once invoked), scanned A, original, Apache-2.0.

A workflow for updating lasting documentation when software behavior changes, instructions become outdated, or new operational or research guidance should be preserved.

In plain words
What is it for?
Use it to update user, operational, skill, or experiment documentation with current behavior, exact commands and paths, and reusable guidance that agrees with the code.
Why use it?
It ensures future users and agents can find accurate procedures without reconstructing them from an issue discussion.

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

update-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 4d 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

Skill: Update Docs

Use this when a task changes behavior, reveals stale instructions, creates a new operational pattern, or produces guidance that should survive outside the issue thread.

What to Update

  • User-facing docs when behavior or configuration changes.
  • Operational docs when commands, service setup, dashboards, alerts, or recovery procedures change.
  • Skill docs when an agent workflow becomes reusable.
  • Experiment reports or indexes when the work produces durable research findings.

Prefer editing the nearest existing doc over adding a new one. Add a new doc only when the topic lacks a natural home or would make an existing page unfocused.

Content Rules

  • Describe current behavior, not aspiration.
  • Include exact commands and paths for operational procedures.
  • Remove or correct stale instructions rather than adding caveats around them.
  • Keep broad docs concise; put detailed run notes in logbooks or issue comments.

Done Criteria

  • Docs and code agree for the changed behavior.
  • The next agent or human can find the authoritative procedure without reading the whole issue thread.
  • Any generated guidance is generalized enough to reuse and specific enough to act on.

Follow .agents/skills/writing-style/SKILL.md for writing-style guidance.

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.
