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.

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 | $0.00036 | $0.00527 |
| Opus 5 | $0.00018 | $0.00264 |
| Sonnet 5 | $0.00007 | $0.00105 |
| Haiku 4.5 | $0.00004 | $0.00053 |
Grade A, and why
gentle-ai-cognitive-doc-design 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 8d 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.
This is a copy
97% identical to cognitive-doc-design — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to Use
Load this skill when creating or editing documentation that people need to understand quickly, retain, or use during review.
Use it especially for:
- PR descriptions and review notes.
- Contributor or maintainer guides.
- Architecture, workflow, or onboarding docs.
- Any doc that currently feels long, dense, or hard to scan.
Critical Patterns
| Pattern | Rule |
|---|---|
| Lead with the answer | Put the decision, action, or outcome first. Context comes after. |
| Progressive disclosure | Start with the happy path, then add details, edge cases, and references. |
| Chunking | Group related information into small sections. Keep flat lists short. |
| Signposting | Use headings, labels, callouts, and summaries so readers know where they are. |
| Recognition over recall | Prefer tables, checklists, examples, and templates over prose that must be remembered. |
| Review empathy | Design docs so reviewers can verify intent without reconstructing the whole story. |
Documentation Shape
Use this default structure unless the repo already provides a stronger template:
# <Outcome-oriented title>
<One paragraph: what changed, who it helps, and why it matters.>
## Quick path
1. <First action>
2. <Second action>
3. <Verification or expected result>
## Details
| Topic | Decision |
|-------|----------|
| <area> | <concise explanation> |
## Checklist
- [ ] <Reader can confirm this>
- [ ] <Reader can confirm that>
## Next step
<Link or action that continues the workflow.>
PR and Review Docs
When documenting a PR, reduce reviewer burnout by making the review path explicit:
- State what to review first.
- State what is intentionally out of scope.
- Link the previous and next PR when work is chained.
- Keep each section focused on one decision or unit of work.
- Use checklists for acceptance criteria and verification.
Commands
# Check markdown files changed in the current branch
git diff --name-only -- '*.md'
# Inspect PR changed-line count for cognitive load
gh pr view <PR_NUMBER> --json additions,deletions,changedFiles
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.
