Project-specific development instructions for a Python repository that extracts code snippets with Claude.

In plain words
What is it for?
Use it when changing or running that project, including installing dependencies, setting its authentication token, extracting snippets, and running tests.
Why use it?
It gives an agent the repository’s expected layout, setup commands, environment requirements, file limits, and testing conventions.

Instructions file for CodexOpenCode

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

This is cheolwanpark/snippets's own configuration. It tells Codex and OpenCode how to work on snippets 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 snippets 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

snippets 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.

Repository Guidelines

Project Structure & Module Organization

Python 3.12 project with runtime code in src/. Agents that talk to Claude now live in src/agent/ (snippet_extractor.py, prompt.py), shared storage helpers in src/snippet/, and IO/utilities in src/utils/. main.py wires everything into a CLI. Keep new modules under the closest matching package; add integration demos or fixtures under samples/, not in src/.

Environment & Configuration

Install dependencies with uv sync (or pip install -e .) from the repo root. Export CLAUDE_CODE_OAUTH_TOKEN before running the extractor; fail fast if it is missing. Respect the default 1 MB file cap and exclude test fixtures unless --include-tests is passed.

Build, Test, and Development Commands

  • uv run python main.py <path> — scan a file or directory and stream snippets to stdout (snippet limits are auto-calculated per file).
  • uv run python main.py samples --output snippets.txt — write formatted snippets to a file (helpful for manual QA).
  • uv run python -m pytest — placeholder; add tests here when a tests/ package exists. Wrap long runs with CLAUDE_CODE_OAUTH_TOKEN=... uv run ... when scripting.

Coding Style & Naming Conventions

Follow standard Black-compatible formatting (4-space indent, double quotes for docstrings). Type hints are expected on public call surfaces. Loggers use logging.getLogger("snippet_extractor"); reuse it for new components. Class names are PascalCase, functions snake_case, constants UPPER_SNAKE. Prefer dataclasses or NamedTuple for structured payloads.

Testing Guidelines

There is no test suite yet; seed tests/ with pytest modules mirroring the package layout (tests/utils/test_file_loader.py). Name async fixtures with the _event_loop fixture when needed. Target high-value behaviors: file filtering edge cases, storage serialization, and concurrency guard rails. Keep sample fixtures under samples/ to avoid polluting the CLI path.

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.
