Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# AGENTS.md

**pydantic-ai-skills** adds remote skill registries and bundled-file execution to [Pydantic AI](https://ai.pydantic.dev/) Agent Skills. It builds on [`pydantic-ai-harness`](https://github.com/pydantic/pydantic-ai-harness), which owns `SKILL.md` discovery, validation and instruction rendering.

This file provides guidance to coding agents (Claude Code, etc.) when working with code in this repository. `CLAUDE.md` is a symlink to this file — edit this one.

## Scope

Python library (>=3.10) that **complements** harness's `Skills` capability rather than reimplementing it. What this package owns: Git/S3 registries and their composition, the bundled `references/`/`scripts/` layer, sandboxed script execution, `${SKILL_DIR}` resolution, and skills defined in Python.

If a change would duplicate something harness already does, it belongs upstream, not here.

Keep this file to agent-critical defaults. Task-specific detail belongs in [docs/](docs/) (see [Link, Don't Duplicate](#link-dont-duplicate)).

## Commands

```bash
pip install -e ".[test,git,s3,dev]"   # full dev install
pytest                                # all tests (coverage is on by default via pytest.ini)
…

How to install

The exact contents, by fingerprint
mdr add dougtrajano/pydantic-ai-skills/AGENTS.md@sha256:5eaa2fe941715dcc

The line at the top of this page pins the label git:20261003.91dcd8c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
