agents-md

agents-md is a skill for Claude Code from sickn33/agentic-awesome-skills. It costs 31 tokens per session (1,867 once invoked), scanned A, original, MIT.

A procedure for creating, updating, or checking AGENTS.md files, which contain instructions that coding agents should follow in a repository. It bases changes on repository evidence and existing maintainer intent.

In plain words
What is it for?
Use it to document verified commands and paths, maintain instructions in monorepos, remove stale guidance, or reconcile AGENTS.md with other instruction files.
Why use it?
It reduces incorrect or outdated agent instructions and avoids replacing useful project-specific rules with unsupported assumptions.

About the project

AAS Core is a local control plane for coding agents that lets them search a large catalogue of skills, choose a stack, validate it, and create a reproducible plan. It is used to assemble and review agent workflows through its CLI, local MCP server, catalogue, plugins, and Workbench. The catalogue add-ons provide the skills, plugins, bundles, and workflows that AAS Core helps agents select and validate.

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

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 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.

Maintain AGENTS.md from repository evidence

Overview

Create or improve agent instructions that help a coding agent change the repository correctly without rediscovering its workflow. Base every repository-specific command, path, and rule on evidence in the current checkout.

Prefer a focused diff over a wholesale rewrite. There is no universal line limit, required section list, symlink layout, or commit-attribution policy; follow the repository's own needs and maintainer intent.

When to Use

  • The user asks to create, update, shorten, or audit AGENTS.md.
  • A monorepo needs root instructions plus narrower package-level overrides.
  • Existing agent instructions contain stale commands, duplicated policy, or unsupported claims.
  • The user wants to reconcile AGENTS.md with CLAUDE.md, .github/copilot-instructions.md, or other repository instruction files.

Use @agents-generator instead when the task specifically calls for its packaged generation modes, assets, or backup workflow. Use this skill when a maintainer-readable, evidence-first edit is the primary goal.

How It Works

1. Preserve existing intent

Before writing, read every instruction file that applies to the target path, including existing AGENTS.md files and relevant tool-specific files such as CLAUDE.md, GEMINI.md, .github/copilot-instructions.md, and .github/instructions/*.instructions.md.

  • Improve an existing AGENTS.md in place when possible.
  • Preserve accurate maintainer-authored rules and repository-specific policy.
  • Do not replace another tool's instruction file with a symlink unless the user requests it and repository evidence shows identical content is desired.
  • Do not silently choose between conflicting instructions. Follow the higher-priority applicable rule, or ask when the intended policy cannot be established from the repository.

2. Build a bounded evidence map

Inspect only enough of the repository to establish how work is actually done:

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.
