Crucible: Build

What it does

The Build skill is a full-feature pipeline orchestrator for turning ideas into working code. It coordinates interactive design, acceptance-test generation (RED), plan writing, team/task creation, per-task implementers and reviewers, cleanup, adversarial testing, and final quality gates. The skill embeds strict communication and quality-gate requirements: every gate must run to completion and the orchestrator writes periodic pipeline status files for ambient awareness.

When to use it

Use this skill when starting feature development, implementing designs, or running a structured build pipeline that requires test-driven development, staged verification, and repeatable review loops. Trigger phrases include "build", "implement", "add feature", or "start development". It's suited for agents capable of spawning subagents, committing to a git repo, and running tests.

What's included

• Scripts: none embedded in SKILL.md, but the repo includes many prompt templates (plan-writer, build-implementer, cleanup, test-gap-writer, etc.)
• References: extensive procedural rules, checkpoint/handoff manifest conventions, and contract-aware behaviors documented inline
• Instructions: granular step definitions for phases 1–4 (Design, Plan, Execute, Completion), review tiers, refactor mode adaptations, and rollback policies

Compatible agents

Intended for powerful orchestration agents (Opus/Claude Code-like) that can manage subagents, read/write repo files, and run CI. The skill assumes access to git and ability to write status artifacts to disk.
