18 Agents
buildcrew provides 18 specialized agents organized into 6 teams, coordinated by the buildcrew orchestrator.
Build Team
| Agent | Model | Role |
|---|---|---|
| planner | opus | 6 Forcing Questions + 4-Lens Self-Review (CEO, Engineering, Design, QA). Plans scored 1-10 per lens. Numbered acceptance criteria (AC-1 …). |
| designer | opus | UI/UX research + motion engineering. Playwright screenshots, Figma MCP, production components. |
| developer | opus | 6 Implementation Questions + 3-Lens Self-Review (Architecture, Code Quality, Safety). Error Handling Protocol. |
Adversarial Team
| Agent | Model | Role |
|---|---|---|
| plan-challenger | opus | 6-vector attack on the plan BEFORE designer. Verdict APPROVED / REVISE / REJECT — REVISE re-runs the planner (max 2 cycles). |
| spec-challenger | opus | 8-vector attack on the design spec BEFORE developer. Same verdict protocol, applied to the designer. |
Quality Team
| Agent | Model | Role |
|---|---|---|
| qa-tester | sonnet | 5 Test Strategy Questions + Test Map. Edge case generation, confidence-scored findings. |
| browser-qa | sonnet | 4-phase browser testing (orient, explore, stress, judge) via Playwright MCP. Health score 0-100. |
| spec-verifier | sonnet | Spec-compliance gate BEFORE reviewer. Every acceptance criterion verified against the implementation with file:line evidence — PASS/FAIL, FAIL loops back to developer. |
| reviewer | opus | 4-specialist analysis (security, perf, testing, maintainability) + adversarial pass + auto-fix. Runs AFTER spec-verifier PASS. |
| health-checker | sonnet | 3-phase code quality (detect, measure, prescribe). Weighted 0-10 score + trends. |
Security & Ops Team
| Agent | Model | Role |
|---|---|---|
| security-auditor | sonnet | OWASP Top 10 + STRIDE threat model. 10-phase audit with confidence gate. |
| canary-monitor | sonnet | 3-phase post-deploy health (orient, verify, judge). Baseline comparison. |
| shipper | sonnet | 8-point pre-flight + semver + changelog + PR + post-ship verification. |
Thinking & Review Team
| Agent | Model | Role |
|---|---|---|
| thinker | opus | "Should we build this?" — 6 forcing questions, premise challenge, 3 alternatives, cross-model perspective, design doc. |
| architect | opus | Architecture review BEFORE code — scope challenge, component diagrams, data flow, failure modes, test coverage map. |
| design-reviewer | sonnet | UI/UX quality — 8 dimensions scored 0-10, screenshot evidence, specific fixes, WCAG compliance. |
Specialist & Meta
| Agent | Model | Role |
|---|---|---|
| investigator | sonnet | 4-phase root cause debugging. 12 common bug patterns. Edit freeze on unrelated code. |
| qa-auditor | opus | 3 parallel subagents (security, bugs, spec compliance) audit git diffs against design docs. No API key needed. |
| coherence-auditor | opus | Verifies the team actually coordinated — parses Handoff Records, cross-checks source code, outputs a Coordination Score 0-100%. Runs LAST. |
Model Distribution
- 9 Opus (critical thinking): planner, designer, developer, plan-challenger, spec-challenger, reviewer, thinker, architect, qa-auditor
- 9 Sonnet (execution): qa-tester, browser-qa, spec-verifier, health-checker, security-auditor, canary-monitor, shipper, design-reviewer, investigator
- Plus two opus coordinators outside the 18: the
buildcreworchestrator and thecoherence-auditormeta agent.
