Set up autonomous coding agent projects with long-running harnesses using Archon MCP for state management. Creates complete project scaffolds with initializer/coding agent prompts, feature tracking, session handoffs, security configuration, and browser testing integration. Based on Anthropic's effective harnesses guide.

One of 13 test cases the skill fixed. Same model, same prompt, with and without the skill.
During setup questionnaire Phase 3 (Agent Configuration), if the user provides no explicit value for maximum feature count or session iteration limit, what default values are applied?
| Checked | Without skill | With skill |
|---|---|---|
| defaults max features to 30 | Missed | Passed |
| defaults session iteration limit to 50 | Missed | Passed |
The instructions your model reads when the skill loads.
Create fully-configured autonomous coding agent projects that can work across multiple sessions with proper state management, handoffs, and testing. Uses Archon MCP for project/task tracking, enabling persistent state management and context preservation.
