phase-builder

What problem does it solve?

Manually orchestrating multi-step software build phases burns the main agent's context window, loses all progress on session crashes, and skips critical review gates that allow architectural drift and broken features to reach production.

Core Features & Use Cases

• Thin Orchestrator Design: Dispatches background workflows to specialized subagents to keep the main agent's context lean, avoiding the trap of processing raw build/test output inline.
• Resumable Execution: Recovers from crashes automatically using committed git state and task ledgers, so no phase progress is lost even if the session dies mid-build.
• Gated Phase Workflow: Enforces entry go/no-go, pre-acceptance validation, and 11 exit gates aligned with project tenets to ensure every phase meets quality and design standards before merge.
• Use Case: A product team building a new authentication feature can use this skill to run the entire phase end-to-end: from entry review and parallel chunk builds to validation, exit gates, and PR creation, with full crash recovery and tenet compliance.

Quick Start

Use the phase-builder skill to run the full end-to-end workflow for your chosen numbered software build phase, including planning, parallel builds, validation, and PR creation.
