Swarm Coding Skill
Fully autonomous multi-agent software development. Given a plain-English prompt, the swarm designs, implements, tests, and delivers a complete project end-to-end.
Core capability: Code generation via OpenRouter's qwen3-coder model. The orchestrator drives a Planner to create a manifest, then executes specialized worker roles (BackendDev, FrontendDev, QA, DevOps, etc.) in dependency order. All code is written to files; no interactive sessions.
Important: This skill generates code for review and deployment by the user. It does not make business decisions or operate autonomously in production. The user remains responsible for security, compliance, and operational decisions.
How It Works
1. Orchestrator (Planner role) analyzes your prompt, decides tech stack and architecture, and creates a swarm.yaml manifest with tasks and dependencies.
2. Worker agents (BackendDev, FrontendDev, QA, DevOps) are spawned as sub-sessions. Each has a clear persona and works on its assigned files in a shared workspace.
3. Coordination: The orchestrator tracks task completion and dependencies. When a task finishes, it marks it done and starts any unblocked downstream tasks.
4. Conflict avoidance: Files are partitioned by role (Backend owns server/, Frontend owns client/, etc.). If two roles need the same file, the manifest assigns an owner.
5. Quality gates: QA must pass tests before integration; DevOps ensures containerization; no merge without green tests.
6. Deliverable: You get a complete project directory with README, tests, Dockerfile, and optionally a GitHub repo or zip.
Usage
# In your main OpenClaw session, invoke:
/trigger swarm-code "Build a dashboard that shows Moltbook stats and ClawCredit status"
The skill will:
Requirements
.env at workspace root):OPENROUTER_API_KEY β OpenRouter API key with qwen/qwen3-coder access
- Optional: OPENROUTER_MODEL (default: qwen/qwen3-coder), MOCK=1 for dry-run
Important: The orchestrator reads .env from the workspace root (parent directory of this skill) and writes project files to swarm-projects/ and logs to .learnings/ in that same workspace root. Run in an isolated workspace to avoid exposing unrelated secrets.
Configuration
Store your OpenRouter key in .env at the workspace root:
OPENROUTER_API_KEY=sk-or-...
Optional overrides:
OPENROUTER_MODEL=qwen/qwen3-coder
MOCK=1 # dry-run, no API calls
The skill uses qwen/qwen3-coder by default. Ensure your OpenRouter key has that model enabled.
Output
The created project lives in swarm-projects/ and includes:
README.md with run instructionspackage.json (or equivalent)test/ directory with automated testsDockerfile and docker-compose.yml (if applicable)CI/ with GitHub Actions workflow (optional)DECISIONS.md β Project memory documenting key architectural and technical decisions with rationale.learnings/ β Learning logs capturing errors, insights, and feature requestsERRORS.md β Failures, exceptions, and recovery actions
- LEARNINGS.md β Corrections, better approaches, knowledge gaps
- FEATURE_REQUESTS.md β Requested capabilities that don't exist yet
SWARM_SUMMARY.md β Execution summary with role performance, statistics, and next stepsContinuous Improvement
The swarm skill automatically captures learnings during execution to improve future runs:
What Gets Logged
.learnings/ERRORS.md with context and recovery suggestions.learnings/LEARNINGS.md (e.g., "Simplified X by using Y").learnings/LEARNINGS.md when you override a decision.learnings/FEATURE_REQUESTS.md when you ask for something the skill can't doAfter Each Run
ASWARM_SUMMARY.md is generated with:
Promoting Learnings
Over time, review.learnings/ files:
This creates a feedback loop where each swarm run makes the skill smarter.
