pyflow: Instructions file for Codex

AGENTS.md

pyflow AGENTS.md is an instructions file for Codex, OpenCode from ZJU-PL/pyflow. It costs 472 tokens per session, scanned A, original, Apache-2.0.

A repository instruction file for PyFlow, a Python framework that analyses program structure and behaviour. It explains the code layout, validation commands, and focused test suites.

In plain words
What is it for?
It guides agents working on PyFlow's analysis, API, command-line, frontend, and security-checking code.
Why use it?
It gives a coding agent project-specific rules instead of making it guess where code lives or which tests to run. This helps keep changes consistent with the repository.

Instructions file for CodexOpenCode

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

This is ZJU-PL/pyflow's own configuration. It tells Codex and OpenCode how to work on pyflow 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 pyflow 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

pyflow 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Execution guide for coding agents working on PyFlow, a Python static analysis framework. Python >=3.10; install development dependencies with python -m pip install -e ".[dev]" in the project virtual environment.

Layout

Code lives in src/pyflow; tests live in tests.

  • ir, language: intermediate representations and Python language support.
  • analysis: CFG, call graph, IFDS, IPA, CPA, shape, and lifetime analysis.
  • application: program context, pass manager, and pipelines.
  • api: entrypoint declarations and semantic queries.
  • frontend: source extraction, dependency resolution, and object loading.
  • checker: pattern-based and semantic security analysis.
  • cli: command-line entrypoints.

Validation

Start with the smallest relevant suite; broaden coverage for changes spanning subsystems. Add regression tests for bug fixes and document user-visible changes.

Change Focused tests
API queries pytest -q tests/api/test_query_api_regressions.py, then pytest tests/api
CLI pytest tests/cli
IFDS/dataflow pytest tests/ifds tests/cli/test_dataflow.py
Frontend/modules pytest tests/frontend tests/modules
Optimization pytest tests/optimization
Security checkers pytest tests/checker

pytest runs the default non-integration suite. Run integration tests explicitly with pytest -m integration tests/integration.

Use the Black version pinned in pyproject.toml: make format formats src and tests; black --check src tests checks formatting. Other Makefile targets: install, install-dev, test, test-integration, test-cov, lint, type-check, and docs.

For CLI changes, update focused tests, keep help text and defaults consistent, and preserve machine-consumable output compatibility.

Releases

Follow RELEASING.md. Publish through the existing GitHub Actions Trusted Publishing workflow by pushing a version tag. Prefer this workflow over local Twine uploads; never republish an existing PyPI version.

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.
