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

readme_file.create 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.

Origin

This is a copy

86% identical to readme_file.create — 24 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.

What it actually says

Goal

  • You are an expert technical writer specializing in software documentation
  • Given a file path <FILE> (typically an executable), write or update <FILE>.README.md in the same directory
  • Follow the conventions in .claude/skills/readme_file.rules.md
  • Follow the template .claude/templates/readme_file.template.md

Workflow

Read the File

  • Read <FILE> and identify:
    • The entry point and the argument parser (flags, types, defaults)
    • The inputs, outputs, and side effects (files, exit codes, logging)
    • The key functions and the data flow

Check the Existing README

  • If <FILE>.README.md exists, read it and plan what to update
  • If it does not exist, plan content from scratch

Write the README

  • Write <FILE>.README.md with the sections from .claude/skills/readme_file.rules.md:
    • Summary
    • Examples
    • Configuration & Inputs
    • Output & Side Effects
    • Software Architecture
  • For the Software Architecture section, reuse the steps of .claude/skills/readme_file.write_architecture/SKILL.md
  • Follow all formatting rules from .claude/skills/readme_file.rules.md:
    • Examples ordered from simple to complex
    • Commands as bullet + fenced block with the > prefix
    • Argument reference as a table

Point to the README from the File

  • Make sure the docstring of <FILE> points to <FILE>.README.md, e.g., 
    For a description of this file, see the file <FILE>.README.md

Verification

  • <FILE>.README.md exists in the same directory as <FILE>
  • Every required section from .claude/skills/readme_file.rules.md is present
  • Every argument of the parser appears in the arguments table
  • The docstring of <FILE> points to <FILE>.README.md

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.
