gaia-build-agent from amd/gaia is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Build a new GAIA agent with the SDK end-to-end: scaffold the package, write the Agent subclass, register @tool functions, compose reusable tool mixins, set the model + system prompt, and test it locally. Use when creating a NEW agent (a Python class inheriting from the base Agent) for the GAIA repo or a user-authored package, not for tuning an existing agent's prompt (prompt-engineer), adding one tool to an existing class (python-developer). GAIA ships one agent (the flagship) through the TUI…
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
# Building a GAIA Agent How to take an idea to a working, testable GAIA agent — a Python class that runs locally on AI PCs. The full prose walkthrough is [`docs/guides/custom-agent.mdx`](../../../docs/guides/custom-agent.mdx). > Read [`CLAUDE.md`](../../../CLAUDE.md) first — the "No Silent Fallbacks", code-reuse, > testing, and eval rules all apply to a new agent. ## The mental model A GAIA agent is **one Python class** that inherits from the base `Agent` (`src/gaia/agents/base/agent.py`) and exposes capabilities as `@tool`-decorated methods. The base class owns the agent loop, tool registry, state, error recovery, and (via mixins) MCP / OpenAI-API exposure — you write the prompt + the tools, not the plumbing. There are no YAML agent manifests for in-core agents (removed in v0.17.5); an in-repo package under `hub/agents/` adds a `gaia-agent.yaml` manifest on top. ## Steps 1. **Scaffold.** `gaia agent init my-agent` generates a starter package at `./my-agent/`. For a publishable hub package in this repo, add `--layout hub` so it lands at `hub/agents/<id>/python/`: ```bash gaia agent init my-agent -o hub/agents/ --layout hub ``` …

How to install
mdr add amd/gaia/gaia-build-agent@sha256:ee01c943a2111499The line at the top of this page pins the label git:20261019.46c2736, 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.
