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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00034 | $0.01106 |
| Opus 5 | $0.00017 | $0.00553 |
| Sonnet 5 | $0.00007 | $0.00221 |
| Haiku 4.5 | $0.00003 | $0.00111 |
Grade A, and why
documentation-quality 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.
How it starts
The opening of the file, as written. The whole thing — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Documentation Quality Standards
Use this skill when documentation should be judged against explicit standards instead of subjective preference.
- Leverage native parallel subagent dispatch and 200k+ context windows where available.
Activation Conditions
Use symptom -> action triggers: when one matches, apply this skill and verify with the protocol below.
- Reviewing docs before merge
- Creating or updating a style guide
- Defining expectations for examples, structure, and terminology
- Auditing a docs set for consistency and readability
Core Standards
- Clear audience and scope
- Stable heading hierarchy
- Runnable or honest examples
- Consistent terminology
- Explicit edge cases, constraints, and failure modes
Documentation Stack Reference
Inherit the shared stack from documentation-patterns: source-of-truth discovery, audience framing, structure selection, verification, and freshness checks. Keep this skill focused on quality gates instead of restating the full stack.
Anti-Patterns
- Writing for the author instead of the reader: It bakes in unstated context and leaves the actual audience unsure what to do next.
- Skipping concrete examples or commands: Abstract guidance is easy to approve and hard to apply correctly.
- Letting links, screenshots, or versions drift: Polished formatting does not help if the instructions are no longer true.
Verification Protocol
Before claiming "skill applied successfully":
- Pass/fail: The Documentation Quality output identifies audience, purpose, source of truth, and freshness requirements.
- Pass/fail: Shared documentation-stack guidance is referenced instead of duplicating another documentation skill.
- Pass/fail: Claims, links, commands, examples, and screenshots are verified or explicitly marked unverified.
- Pressure-test scenario: Apply the skill to a doc request with a stale command, missing owner, and conflicting audience.
- Success metric: Zero undocumented assumptions; every reader-facing claim is sourced or scoped.
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-quality is a skill published in the GitHub repository PracticalSwan/agent-skills (13 stars, last pushed 4d ago), licensed MIT. It adds 34 tokens to every session and 1,106 once invoked, about $0.0002 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.
