Why use it?
It gives agents the project’s build, test, style, and security rules, including how to avoid committing secrets or machine-specific paths.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is JoeyBe1/mcp-augment's own configuration. It tells Codex and OpenCode how to work on mcp-augment itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-augment configures →

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

mcp-augment 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 2mo 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 — Guidelines for agents in this repository

This file is the public agent brief for the mcp-augment project. It omits private workflow rules that belong only in a full dev checkout.

Project

  • Purpose: Provide an MCP server and hook layer so AI coding tools can enforce safer file and shell operations (safe_* tools + Pre/Post hook chain).
  • Language: Python 3.10+
  • Key paths: project-tools/mcp-hooks-server/, .kilo/hooks/, tests/.

Build / test

export PROJECT_DIR="$(pwd)"   # repository root; required for many tests and runtime
pip install -U pip mcp
pip install pytest hatchling    # hatchling if you use pip install -e . once wheel layout exists
pip install -e .               # optional; prod tree may use pip install mcp + pytest only
pytest tests/ -q --tb=short

For HTTP integration tests, start the stack (see root README.md), then run python3 tests/mcp_protocol_test.py and related smoke tests.

Code style

  • Prefer clear, small functions; type hints on public APIs.
  • Follow existing patterns in project-tools/mcp-hooks-server/.
  • Do not commit secrets, API keys, or machine-specific absolute paths in shipped files.

Scope

  • Keep changes focused on the user-facing MCP + hooks story.
  • Propose larger refactors in an issue or PR description before broad rewrites.
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.
