Claude Code skills collection — build pipelines, TDD, debugging, code review, and more
A collection of agent skills for systematic software development. Works with Claude Code, Cursor, OpenAI Codex, Amp, Cline, and any platform that supports the SKILL.md format.
52 skills across the full development lifecycle — design, planning, TDD implementation, code review, debugging, adversarial testing, and quality gates. 13 core skills are eval-tested with measured A/B deltas (49 execution evals + 18 sequence evals, +29% / +31% average).
Originally forked from obra/superpowers, now independently maintained and significantly diverged. Pipeline checkpoint system, auto skill extraction, structured context compression, and trajectory capture inspired by NousResearch/hermes-agent.

| Cursor / Codex / Amp / Cline | Compatible — same SKILL.md format |
quality-gate loops until clean (red-team → fix → fresh re-review), with weighted stagnation detection. Measured +68% delta (see eval results).build chains design → plan → execute → complete with shadow-git checkpoints, crash recovery, and structured compaction-state blocks. One command, idea to merged PR.adversarial-tester writes tests designed to break the implementation; inquisitor runs 5 parallel attack dimensions against the full feature diff; siege runs 6 attacker-perspective security agents until zero Critical/High./tmp, only ~100-token pointers enter orchestrator context. A full build saves 73-131K tokens of fossilized context.replay resumes interrupted pipelines from the last phase boundary (10 minutes, not 90); recall queries a searchable session activity index that survives compaction.temper runs fresh-eyes review loops on PRs from any platform (GitHub, GitLab, Bitbucket, self-hosted) or raw <base>..<head> ranges. Multi-round convergence with stagnation detection; optional external-model second opinion via MCP. Renamed from /code-review to avoid collision with Claude Code's built-in /review.See docs/architecture.md for how the orchestrator skills compose, and docs/skills.md for the full catalog.
git clone git@github.com:raddue/crucible.git ~/repos/crucible
ln -sf ~/repos/crucible/skills/* ~/.claude/skills/
mkdir -p ~/.claude/agents
ln -sf ~/repos/crucible/agents/* ~/.claude/agents/
Or, when available on the marketplace: claude plugin install raddue/crucible. Note: the per-role model pins are currently delivered by the symlink install above — under a plugin install the agent types are namespaced (crucible:…) and bare-name dispatch resolution is unconfirmed (see harness-adapter §8).
git clone git@github.com:raddue/crucible.git ~/repos/crucible
Then point your platform at the cloned skills directory. See Cursor plugin docs and Codex skills docs. Some advanced features (parallel subagent dispatch, agent teams, persistent memory) are platform-specific and degrade gracefully — see PLATFORMS.md.
Run in auto mode for autonomous pipelines (/build, /debugging, long /quality-gate runs). Auto mode lets Claude execute tool calls without per-action prompts while still confirming destructive operations. It supersedes earlier --dangerously-skip-permissions guidance.
Set CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 for build's parallel team execution. Without it, independent tasks fall back to sequential dispatch — everything still works, just slower.
Recommended but optional: enable the forge (retrospectives) and cartographer (codebase map) knowledge accelerators — they compound skill quality over time. See docs/architecture.md.
For hooks (session activity index, build routing advisor), MCP-based external model review, autocompact tuning, and other Claude Code specifics, see docs/configuration.md.
