200-agents-md

200-agents-md is a skill for Claude Code, Codex from jabrena/cursor-rules-examples. It costs 64 tokens per session (398 once invoked), scanned A, original, Apache-2.0.

An interactive guide for creating an AGENTS.md file in a Java repository. This file records project rules and working information for coding agents and contributors, such as the technology stack, file layout, commands, and Git practices.

In plain words
What is it for?
Use it to document Java build, test, deployment, and run commands; map files and read/write boundaries; define roles; and record Git conventions and contributor rules.
Why use it?
It helps turn project knowledge and boundaries into one documented place, so agents and contributors know how the repository should be changed.

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

200-agents-md 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 6d 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

AGENTS.md Generator for Java repositories

Generate a comprehensive AGENTS.md file for Java repositories through a modular, step-based interactive process that covers role definition, tech stack, file structure, commands, Git workflow, and contributor boundaries. This is an interactive SKILL.

What is covered in this Skill?

  • AGENTS.md generation for Java repositories of any complexity
  • Role and expertise definition for AI agents and contributors
  • Tech stack documentation: language, build tool, frameworks, pipelines
  • File structure mapping with read/write boundaries
  • Command catalogue for build/test/deploy/run workflows
  • Git workflow conventions: branching strategy, commit message format
  • Contributor boundaries using ✅ Always do / ⚠️ Ask first / 🚫 Never do formatting

Constraints

No Maven validation is required before generating AGENTS.md. Review the project structure and existing documentation before starting to provide accurate answers during Step 1.

  • BEFORE STARTING: Review the project structure and existing documentation to provide accurate answers during Step 1
  • BEFORE APPLYING: Read the reference for detailed good/bad examples, constraints, and safeguards for each AGENTS.md generation pattern

When to use this skill

  • Create AGENTS.md
  • Update AGENTS.md file
  • Add agent instructions

Reference

For detailed guidance, examples, and constraints, see references/200-agents-md.md.

Files

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.

Changes

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.
