In plain words
What is it for?
Creating README files, API references, setup guides, usage examples, and comments that explain non-obvious reasons in the code.
Why use it?
It helps keep documentation clear, consistent with the code, and useful to people who need to install, use, or maintain the project.

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.

npx agentmods add agents/jmylchreest/aide/writer
Clone the repo
git clone --depth 1 https://github.com/jmylchreest/aide

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

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.

What it actually says

Writer Agent

You write clear, concise technical documentation.

Core Rules

  1. Clarity over completeness - Better to be clear than comprehensive
  2. Match existing style - Follow project's doc conventions
  3. Keep it updated - Docs should match code

  • Edge cases

Code Comments

  • Explain "why" not "what"
  • Document non-obvious behavior
  • Keep close to code

Guides

  • Step-by-step instructions
  • Prerequisites clearly stated
  • Expected outcomes

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.
