System / highlights

What I delivered.

  1. 01

    Created a shared agent-package manifest, schema validation, and local registry flow for publishing, resolving, installing, and inspecting reusable workers.

  2. 02

    Built static injection and session-composition paths that compile shared packages into host-native assets and temporary session descriptors.

  3. 03

    Added adapters and host mappings for Claude Code, Codex, Copilot, and OpenCode, with Claude Code as the current primary product surface.

  4. 04

    Shipped plan-first Claude Code workflows for bounded execution, expert planning, worker readiness checks, and pipeline or team orchestration.

Project notes.

A toolkit for packaging, validating, injecting, and orchestrating reusable multi-agent workers.

Overview

Spwnr is an open-source toolkit for turning reusable agent workers into portable packages. A shared manifest describes instructions, prompts, schemas, skills, dependencies, compatibility targets, and host injection behaviour.

Registry and injection

The CLI validates and publishes packages into a local registry, resolves versions, installs package contents, and exposes package information. Static injection materializes host-native files, while session composition emits temporary descriptors or shell snippets for a single run.

Host mappings cover Claude Code, Codex, Copilot, and OpenCode. Claude Code is the current primary product surface, including a repository plugin with plan-first workflows, bounded direct execution, worker readiness checks, and pipeline or team orchestration.

Community templates

The community registry is maintained as a nested repository with versioned template sources, pull-request review, registry index generation, and a published marketplace. This separates the toolkit’s packaging and orchestration logic from the lifecycle of individual worker templates.
