docker-agent Examples

This directory is a curated catalog of working agent configurations. Each example demonstrates one or more features of docker-agent and is meant to be read as documentation as well as run as-is.

Running an example

The canonical way to run any of them is:

$ docker agent run examples/<name>.yaml

Add -c <command> to invoke one of the agent's commands, --exec to skip the TUI, or -a <agent> to run a specific agent from a multi-agent file. A handful of examples (e.g. tic-tac-toe.yaml, elicitation/, eval/) ship a small README of their own with extra setup instructions — read those before running.

Most agents need API keys for at least one provider (OpenAI, Anthropic, Google, Mistral, Nebius, Groq, GitHub Models, Bedrock, …). Set the matching environment variable (OPENAI_API_KEY, ANTHROPIC_API_KEY, …) before running, or wire the agent to a key your gateway/proxy already holds.

The rest of this document groups examples by what feature they showcase. If you are looking for inspiration to build a real agent, jump to Real-world agents.

Built-in toolsets

Examples that wire up one of the toolsets shipped with docker-agent (filesystem, shell, background_jobs, todo, think, memory, fetch, script, user_prompt, api, openapi, rag, model_picker, …).

Conventions

• YAML is the recommended format. HCL is also supported (*.hcl); the pirate.{yaml,hcl}, gopher.{yaml,hcl} and instructions_from_file.hcl pairs show equivalent agents in both formats.
• Every example references the JSON schema at agent-schema.json — point your editor at it for autocomplete and validation.
• Examples target the latest schema version. Older config versions live under pkg/config/v0, v1, … and are intentionally frozen; new features only land on the latest version.
