pygase: Instructions file for Codex

AGENTS.md

pygase AGENTS.md is an instructions file for Codex, OpenCode from sbischoff-ai/pygase. It costs 1,067 tokens per session, scanned A, original, MIT.

A contributor guide for Pygase, a Python library for networked games or applications. It maps the connection, client, server, and shared game-state code and lists the project’s standard checks.

In plain words
What is it for?
Use it when changing Pygase’s UDP networking, client and server behavior, synchronized state, or tests.
Why use it?
It helps an agent find the right module and run the expected formatting, type-checking, linting, documentation, and test commands.

Instructions file for CodexOpenCode

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

This is sbischoff-ai/pygase's own configuration. It tells Codex and OpenCode how to work on pygase 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 pygase 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

pygase 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.

AGENTS.md

Architecture map (quick orientation)

  • pygase/connection.py: protocol and transport core. Defines package/header serialization, sequence/ack tracking, connection status, and client/server connection classes that send and receive UDP datagrams.
  • pygase/backend.py: server-side orchestration layer. Wraps lower-level connection behavior with backend lifecycle management, event dispatch wiring, and game loop integration.
  • pygase/client.py: client-facing API. Manages connecting/disconnecting to a backend, event exchange, and synchronized state consumption for game/application code.
  • pygase/gamestate.py: authoritative state model and update mechanics. Defines game state containers, ordered updates, and merge/apply behavior used by both client and backend flows.

Canonical uv commands

  • Setup (dev env + editable install):
    • uv sync
  • Format:
    • uv run black pygase tests
  • Type-check:
    • uv run mypy pygase
  • Lint/docstyle:
    • uv run pylint --fail-under=9.9 pygase
    • uv run pydocstyle pygase
  • Targeted tests (single file or subset):
    • uv run pytest -m "not integration" tests/connection_test.py
    • uv run pytest -m "not integration" tests -k connection
  • Quick default test pass (fast feedback):
    • uv run pytest -m "not integration" tests
  • Integration tests only:
    • uv run pytest -m integration tests
  • Full tests (match CI intent):
    • uv run pytest tests --doctest-modules --cov=pygase --cov-report=term-missing

Fast path vs full validation

  • Fast path (small, local edits that do not affect protocol, networking, or cross-module behavior):
    1. uv run black pygase tests
    2. uv run pytest -m "not integration" tests/<affected_module>_test.py
    3. uv run mypy pygase (required before finishing any task)
  • Full validation (required for protocol/network behavior edits, connection timing/ordering changes, or broad refactors):
    1. uv run black pygase tests
    2. uv run pytest tests --doctest-modules --cov=pygase --cov-report=term-missing
    3. uv run mypy pygase
    4. uv run pylint --fail-under=9.9 pygase
    5. uv run pydocstyle pygase

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.
