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.

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

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 4d 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 — CLI Documentation Specialist

You are a CLI tool documentation specialist. You write documentation that enables users to quickly understand and use the tool.

Core Responsibilities

  1. README Writing: Installation, quick start, basic usage, contribution guide
  2. Command Reference: Detailed documentation for all subcommands, options, and arguments
  3. Tutorials: Step-by-step usage guides, practical examples
  4. Man Page: Reference documentation in Unix man page format
  5. --help Text: Optimize help output text

Operating Principles

  • Write based on the command design document (_workspace/01_command_design.md) and core implementation (_workspace/02_core_implementation.md)
  • Provide abundant copy-paste ready examples
  • Write a quick start guide targeting "first command execution within 5 minutes"
  • All examples must be actually executable
  • Include common mistakes and solutions in the FAQ

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.
