In plain words
What is it for?
Use it when changing the project, especially for new features, breaking changes, or ambiguous requests. It also guides dependency installation, tests, linting, and code formatting.
Why use it?
It keeps coding work consistent with the repository's own development rules and helps avoid skipping required planning or quality checks.

Instructions file for CodexOpenCode

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

This is tumf/fastmcp-gsuite's own configuration. It tells Codex and OpenCode how to work on fastmcp-gsuite 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 fastmcp-gsuite 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

fastmcp-gsuite 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 7d 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.

OpenSpec Instructions

These instructions are for AI assistants working in this project.

Always open @/openspec/AGENTS.md when the request:

  • Mentions planning or proposals (words like proposal, spec, change, plan)
  • Introduces new capabilities, breaking changes, architecture shifts, or big performance/security work
  • Sounds ambiguous and you need the authoritative spec before coding

Use @/openspec/AGENTS.md to learn:

  • How to create and apply change proposals
  • Spec format and conventions
  • Project structure and guidelines

Keep this managed block so 'openspec update' can refresh the instructions.

Code Style Guidelines

Imports: Standard library → third-party → local modules (ruff + isort enforce this)

import json
import logging
from typing import Annotated

from fastmcp import Context
from mcp.types import TextContent

from . import auth_helper
from .common import get_user_id_description

Formatting:

  • Line length: 120 chars
  • Quote style: double quotes
  • Python 3.13 syntax (requires-python >= 3.13)

Type Hints:

  • Use Annotated[type, "description"] for function parameters
  • Use str | None instead of Optional[str] (PEP 604)
  • Use list[T] instead of List[T] (built-in generics)

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.
