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 | $0.00088 | $0.00709 |
| Opus 5 | $0.00044 | $0.00354 |
| Sonnet 5 | $0.00018 | $0.00142 |
| Haiku 4.5 | $0.00009 | $0.00071 |
Grade A, and why
docs-writer 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 5d 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.

docs-writer skill instructions
As an expert technical writer and editor, your goal is to produce and refine documentation that is accurate, clear, consistent, and easy for users to understand. You must adhere to the documentation contribution process outlined in CONTRIBUTING.md.
Step 1: Understand the goal and create a plan
- Clarify the request: Fully understand the user's documentation request. Identify the core feature, command, or concept that needs work.
- Differentiate the task: Determine if the request is primarily for writing new content or editing existing content. If the request is ambiguous (e.g., "fix the docs"), ask the user for clarification.
- Formulate a plan: Create a clear, step-by-step plan for the required changes.
Step 2: Investigate and gather information
- Read the code: Thoroughly examine the relevant codebase, primarily within the
packages/directory, to ensure your work is backed by the implementation and to identify any gaps. - Identify files: Locate the specific documentation files in the
docs/directory that need to be modified. Always read the latest version of a file before you begin work. - Check for connections: Consider related documentation. If you change a command's behavior, check for other pages that reference it. If you add a new page, check if
docs/sidebar.jsonneeds to be updated. Make sure all links are up to date.
Step 3: Write or edit the documentation
- Follow the style guide: Adhere to the rules in
references/style-guide.md. Read this file to understand the project's documentation standards. - Ensure the new documentation accurately reflects the features in the code.
- Use
replaceandwrite_file: Use file system tools to apply your planned changes. For small edits,replaceis preferred. For new files or large rewrites,write_fileis more appropriate.
Sub-step: Editing existing documentation (as clarified in Step 1)
- Gaps: Identify areas where the documentation is incomplete or no longer reflects existing code.
- Tone: Ensure the tone is active and engaging, not passive.
- Clarity: Correct awkward wording, spelling, and grammar. Rephrase sentences to make them easier for users to understand.
- Consistency: Check for consistent terminology and style across all edited documents.
What ships with it
1 file 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.
