Instructions file for CodexOpenCode

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

This is clchinkc/document-mcp's own configuration. It tells Codex and OpenCode how to work on document-mcp 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 document-mcp 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

document-mcp 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.

Agent Usage Guide

The Document MCP system includes two AI agents that demonstrate how to use the MCP tools effectively. These agents are separate from the core MCP package and run directly from source code.

Latest Updates (v0.0.3)

  • ✅ Pagination Support: All agents now work with the new pagination system for large documents
  • ✅ GCP Observability: All tool calls now traced with logs/metrics (works locally too)
  • ✅ OpenRouter Support: Use OpenRouter models with priority over OpenAI and Gemini
  • ✅ Tool Selection Benchmarks: Evaluation framework for measuring agent tool selection accuracy
  • ✅ Enhanced Testing: Complete test coverage with 536 tests passing (61% coverage)
  • ✅ Improved Error Handling: Better timeout management for E2E scenarios

Prerequisites

  1. Install the MCP package (for the core tools):

    pip install document-mcp
    
  2. Clone the repository (for the agents):

    git clone https://github.com/your-org/document-mcp.git
    cd document-mcp
    
  3. Install agent dependencies:

    uv sync --dev
    # or
    pip install -r requirements-agents.txt
    
  4. Set up API keys (choose one, priority order: OpenRouter > OpenAI > Gemini):

    # For OpenRouter (recommended - access to multiple models)
    export OPENROUTER_API_KEY="your-openrouter-key"
    
    # For OpenAI
    export OPENAI_API_KEY="your-openai-key"
    
    # For Google Gemini
    export GEMINI_API_KEY="your-gemini-key"
    

    Or create a .env file in the project root (see .env.example).

Agent Types

Simple Agent

Best for: Quick operations, single-step tasks, structured JSON output

# Basic usage
uv run python src/agents/simple_agent/main.py --query "list all documents"

# With specific model
uv run python src/agents/simple_agent/main.py --query "create document 'Meeting Notes'" --model "gemini-2.5-flash"

# Interactive mode
uv run python src/agents/simple_agent/main.py --interactive

# Check configuration
uv run python src/agents/simple_agent/main.py --check-config

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.
