mcp-replay-dota2: Instructions file for Codex

AGENTS.md

mcp-replay-dota2 AGENTS.md is an instructions file for Codex, OpenCode from DeepBlueCoding/mcp-replay-dota2. It costs 672 tokens per session, scanned A, original, MIT.

A repository instruction file for a Python MCP server related to Dota 2 match data. It documents the project layout, development commands, style rules, and testing approach.

In plain words
What is it for?
It helps locate runtime modules and data, install the pinned environment with uv, launch the server, refresh cached constants, run tests, and follow the project’s Python conventions.
Why use it?
It gives coding agents and contributors the project-specific context needed to change the repository safely and run it correctly.

Instructions file for CodexOpenCode

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

This is DeepBlueCoding/mcp-replay-dota2's own configuration. It tells Codex and OpenCode how to work on mcp-replay-dota2 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-replay-dota2 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-replay-dota2 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 1mo 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.

Repository Guidelines

Project Structure & Module Organization

src/ holds runtime modules: resources/ surfaces MCP-ready data (for example heroes_resources.py), tools/ wraps FastMCP utilities, and utils/ provides shared helpers for constants, fuzzy search, and replays. Root scripts (dota_match_mcp_server.py, main.py) are the entry points; data caches and artifacts live in data/, while maintenance helpers (like scripts/fetch_constants.py) keep them current. Primary tests live in tests/, and pytest still collects legacy root files such as test_fuzzy_search.py.

Build, Test, and Development Commands

uv sync                                  # install pinned Python 3.12 environment
uv run python dota_match_mcp_server.py   # launch the stdio FastMCP server
uv run python main.py                    # smoke test the package entry point
uv run pytest                            # execute the suite with pytest.ini settings
uv run python scripts/fetch_constants.py # refresh dotaconstants caches in data/

Use uv run so imports resolve inside the managed venv.

Coding Style & Naming Conventions

Stick to 4-space indentation, type hints, and docstrings as shown in src/utils/hero_fuzzy_search.py. Prefer snake_case functions, CapWords classes, and SCREAMING_SNAKE_CASE constants (see src/utils/constants.py). Keep FastMCP resource IDs in the dota2:// namespace, ensure regenerated JSON stays lowercase_with_underscores, and wire any formatter or linter through pyproject.toml so it can run via uv run.

Testing Guidelines

pytest.ini scopes discovery to tests/ plus test_*.py, enables verbose output, short tracebacks, and strict marker validation. Mirror the production layout for new tests (e.g., tests/test_heroes_resources.py), quarantine replay fixtures under data/fixtures/, and tag network- or replay-heavy suites with @pytest.mark.integration or @pytest.mark.slow. Gate those locally through uv run pytest -m "not slow" and favor assertions that validate hero IDs, alias coverage, and replay parsing results.

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.
