documentation-guidance

A set of project rules for keeping documentation, generated agent instructions, and automatic review guidance in the right files.

In plain words
What is it for?
Use it when changing documentation ownership, environment or configuration references, generated skills, or review auto-fix guidance.
Why use it?
It reduces duplicated or outdated instructions by assigning each fact to one documentation source and describing how generated guidance must be updated.

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-guidance 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

Documentation

  • Keep README.md concise and high-level; the bar needs to be extremely high for what shows up there.
  • Most documentation lives in docs/, the published docs site.
  • One owner per fact: docs/src/content/docs/reference/global-config.md and docs/src/content/docs/reference/repo-config.md own configuration keys, docs/src/content/docs/reference/environment.md owns environment variables and the telemetry local/remote split, docs/src/content/docs/concepts/daemon.md owns the daemon lifecycle model, and guides pages explain purpose and link to those owners instead of restating tables and examples.
  • The document.instructions block in .no-mistakes.yaml states this ownership map for the pipeline's document step; update it when ownership moves.

Agent-Guidance Surfaces

  • skills/no-mistakes/SKILL.md is generated: the source of truth is the body constant in internal/skill/skill.go. Edit the body, then make skill; make lint fails CI on drift. Never edit SKILL.md directly. no-mistakes init ships this rendering to agents at user level.
  • Agent-driving guidance is owned by the skill body and the live axi output strings (internal/cli/axi*.go); docs/src/content/docs/guides/agents.md carries only the canonical invariant sentences pinned by internal/cli/axi_guidance_test.go plus a pointer to the skill. When you change driving guidance, change the skill body and the point-of-use axi strings together; that drift test is the sync check.
  • The shared default test-quality rule lives in internal/testguidance; render it only into the task-first skill and pipeline roles that can author, repair, or review tests. Its fake-agent prompt tests are the intentional generated-interface contract, not source-text checks.
  • Review auto-fix is disabled by default (auto_fix.review: 0 in config.go autoFixDefaults), so blocking and ask-user review findings park for an agent decision; keep the skill, the live axi gate note, and docs qualified if you touch review auto-fix.
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.

documentation-guidance is a skill published in the GitHub repository kunchenguid/no-mistakes (7,965 stars, last pushed yesterday), licensed MIT. It adds 21 tokens to every session and 501 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 2026-08-30.
