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.
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.
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.
Crucible: Build is an extensive orchestration skill (75K chars, 1100+ lines) that runs a full dev pipeline from design through execution with quality gates, TDD, and iterative review. No scripts bundled — pure instruction-based orchestration for AI agents. The SKILL.md is exceptionally detailed with clear phase boundaries, escalation triggers, compaction recovery, and a health state machine. No security concerns found: no shell execution, no network calls, no credential handling, no destructive commands. The main risk is the skill's sheer size causing context bloat, though compression/handoff mechanisms are well-designed to mitigate this.
This is a sophisticated, well-structured orchestration skill for running multi-phase development pipelines. It's one of the most detailed skills seen — the quality gate enforcement, compaction recovery, and phase handoff mechanisms are production-grade thinking. Security is clean: no code execution, no network calls, no credential handling. The main architectural concern is the monolithic 75K SKILL.md that could benefit from progressive disclosure (moving detailed specs to references/). The skill is highly useful for teams running structured dev pipelines with Claude Code, but niche in that it requires the full Crucible skill suite and Claude Code agent features.
