📖 Quick Start

Initialize a New Agent

Create a new agent from the APS template:

aps init my-agent
cd my-agent

This scaffolds a complete agent structure with:

• aps/agent.yaml — Manifest with metadata, runtime, dependencies
• src/<agent_name>/main.py — Example Python entrypoint
• src/<agent_name>/__init__.py — Python package initialization
• AGENT_CARD.md — Agent documentation

Validate Your Agent

Check that your manifest is correctly structured:

aps validate .

Run Your Agent

Execute the agent locally with JSON input/output:

echo '{"text": "hello world"}' | aps run .

Or use the --input flag:

aps run . --input '{"text": "hello world"}'

Build a Package

Create a distributable .aps.tar.gz package:

aps build .

This produces dist/dev.my-agent.aps.tar.gz containing the manifest, code, and metadata.

Sign Your Package

Generate a keypair (first time only):

aps keygen

Sign the package for verification and provenance:

aps sign dist/dev.my-agent.aps.tar.gz --key default

Verify a Package

Verify the signature and integrity:

aps verify dist/dev.my-agent.aps.tar.gz --pubkey ~/.aps/keys.pub/default.pub

Publish to a Registry

Push your built package to a registry:

aps publish dist/dev.my-agent.aps.tar.gz --registry http://localhost:8080

Pull from a Registry

Download an agent from a registry:

aps pull dev.echo --registry http://localhost:8080
