session-buddy: Instructions file for Codex

AGENTS.md

session-buddy AGENTS.md is an instructions file for Codex, OpenCode from lesleslie/session-buddy. It costs 658 tokens per session, scanned B, original, BSD-3-Clause.

Repository instructions for session-buddy, describing its code layout, development commands, quality checks, and testing practices.

In plain words
What is it for?
Finding where to add runtime, CLI, tool, utility, documentation, or test code, then installing dependencies and running formatting, type, security, complexity, and test checks.
Why use it?
It gives contributors the project’s local rules so new code fits the existing structure and can be checked in the same way as the rest of the repository.

Instructions file for CodexOpenCode

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

This is lesleslie/session-buddy's own configuration. It tells Codex and OpenCode how to work on session-buddy 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 session-buddy 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 B, and why

session-buddy AGENTS.md scanned grade B with 1 finding 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.

Reads MCP configurationmediumAgent snooping

mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.

- Store MCP client configs as `example.mcp.json` derivatives and keep secrets out of version control.

Repository Guidelines

Project Structure & Module Organization

  • session_buddy/ hosts the runtime server (server.py), CLI entrypoint (cli.py), and integration adapters such as crackerjack_integration.py.
  • Feature logic belongs in session_buddy/core/, session_buddy/tools/, and session_buddy/utils/; keep new modules narrow, protocol-driven, and well-typed.
  • Tests reside in tests/ with fixtures under tests/fixtures/ and strategy notes in tests/README.md; mirror package paths when adding cases.
  • Documentation lives in docs/; generated assets (dist/, htmlcov/, coverage outputs) should remain untouched.

Build, Test, and Development Commands

  • uv sync --group dev installs reproducible runtime and development dependencies.
  • uv run session-buddy start boots the MCP server locally; uv run session-buddy status confirms port 8678.
  • uv run pre-commit run --all-files executes Ruff, Pyright, Bandit, Complexipy, and related quality gates while applying safe fixes.
  • Use Crackerjack as the canonical repo-wide quality and CI/CD gate when validating larger changes or matching CI locally.
  • uv run pytest --cov=session_buddy --cov-report=term-missing runs the suite with coverage; append --maxfail=1 during rapid iteration.

Coding Style & Naming Conventions

  • Target Python 3.13 with explicit type hints; import typing as import typing as t and reference annotations via t. prefixes.
  • Prefer pathlib.Path, f-strings, dataclasses, and protocol interfaces; avoid docstrings unless an API contract demands them.
  • Keep functions short (cognitive complexity ≤13), adopt descriptive snake_case, and consolidate shared helpers within utils/.

Testing Guidelines

  • Pair every module with pytest cases that mirror its path (e.g., session_buddy/foo.py → tests/unit/test_foo.py).
  • Reuse the async fixtures provided; mark temporary failures with @pytest.mark.xfail and link the tracking issue.
  • Maintain the march toward 85% coverage; regenerate HTML via uv run pytest --cov ... --cov-report=html and review htmlcov/index.html before submitting.

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.
