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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.00704 |
| Opus 5.5 | $0.00018 | $0.00282 |
| Sonnet 5.5 | $0.00009 | $0.00141 |
| Haiku 4.5 | $0.00005 | $0.00070 |
Grade A, and why
documentation-guidelines 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 27d 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.
How it starts
The opening of the file, as written. The whole thing — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Documentation Guidelines
Capture durable meaning that code alone does not explain: business intent, ownership, invariants, permissions, contracts, and operational decisions. Let source and tests own implementation details and executable evidence.
Delegation
Run in the main conversation by default. Delegation can increase usage: obtain explicit approval for the proposed agent count and scope before using subagents. Reuse that approval within its bounds; ask again before expanding the approved count or scope.
Find the owner and evidence
Read the relevant documentation index and owner when present, then verify affected facts against source, tests, schemas, configuration, and runtime evidence. Follow links needed to understand the changed contract; stop when further reading no longer affects the result. Missing or stale documentation is a reason to inspect source, not a prerequisite that blocks work.
For the scope at hand, identify applicable actors, triggers, rules, state transitions, inputs/outputs, side effects, failure paths, ownership, and compatibility requirements. Omit irrelevant categories; record unresolved material facts without inventing them.
Change docs when durable meaning changes
| Change | Documentation action |
|---|---|
| Internal refactor, formatting, or fix restoring documented behavior | Update only affected paths or evidence anchors, if any |
| User behavior, business rule, or workflow | Update its existing owner |
| API, schema, permissions, events, or compatibility | Update the contract and affected consumer mappings |
| Setup, migration, deployment, backup, or recovery | Update the owning runbook |
| Entity renamed, moved, or removed | Repair discovery routes and stale references |
| Duplicate or contradictory docs | Preserve valid facts in one owner, repair links, then remove stale copies within scope |
Avoid docs changes that merely record task activity. Keep transient plans, command logs, and CI output in the task, PR, or an existing evidence surface unless they represent a durable operating requirement.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-guidelines is a skill published in the GitHub repository thienanblog/awesome-ai-agent-skills (70 stars, last pushed 27d ago), licensed Apache-2.0. It adds 45 tokens to every session and 704 once invoked, about $0.0002 per session on Opus 5.5. 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.
