Team Performance Optimization

Profile application performance, identify bottlenecks, design optimization strategies, implement changes, benchmark improvements, and review code quality.

Pipeline (Single mode):
  PROFILE-001 -> STRATEGY-001 -> IMPL-001 -> BENCH-001 + REVIEW-001 (fix cycle)

Pipeline (Fan-out mode):
  PROFILE-001 -> STRATEGY-001 -> [IMPL-B01..N](parallel) -> BENCH+REVIEW per branch

Pipeline (Independent mode):
  [Pipeline A: PROFILE-A->STRATEGY-A->IMPL-A->BENCH-A+REVIEW-A]
  [Pipeline B: PROFILE-B->STRATEGY-B->IMPL-B->BENCH-B+REVIEW-B] (parallel)

Role Registry

| Role | Path | Prefix | Inner Loop | |------|------|--------|------------| | coordinator | roles/coordinator/role.md | — | — | | profiler | roles/profiler/role.md | PROFILE- | false | | strategist | [roles/strategist/role.md](roles/strategist/role.md) | STRATEGY- | false | | optimizer | roles/optimizer/role.md | IMPL-, FIX- | true | | benchmarker | roles/benchmarker/role.md | BENCH- | false | | reviewer | [roles/reviewer/role.md](roles/reviewer/role.md) | REVIEW-, QUALITY- | false |

Role Router

Parse $ARGUMENTS:

• Has --role <name> → Read roles/<name>/role.md, execute Phase 2-4
• No --role → @roles/coordinator/role.md, execute entry router

Shared Constants

• Session prefix: PERF-OPT
• Session path: .workflow/.team/PERF-OPT-<slug>-<date>/
• Team name: perf-opt
• CLI tools: ccw cli --mode analysis (read-only), ccw cli --mode write (modifications)
• Message bus: mcp__ccw-tools__team_msg(session_id=<session-id>, ...)

Worker Spawn Template

Coordinator spawns workers using this template:

Agent({
  subagent_type: "team-worker",
  description: "Spawn <role> worker",
  team_name: "perf-opt",
  name: "<role>",
  run_in_background: true,
  prompt: `## Role Assignment
role: <role>
role_spec: <skill_root>/roles/<role>/role.md
session: <session-folder>
session_id: <session-id>
team_name: perf-opt
requirement: <task-description>
inner_loop: <true|false>

## Progress Milestones
session_id: <session-id>
Report progress via team_msg at natural phase boundaries (context loaded -> core work done -> verification).
Report blockers immediately via team_msg type="blocker".
Report completion via team_msg type="task_complete" after final SendMessage.

Read role_spec file (@<skill_root>/roles/<role>/role.md) to load Phase 2-4 domain instructions.
Execute built-in Phase 1 (task discovery) -> role Phase 2-4 -> built-in Phase 5 (report).`
})

Inner Loop roles (optimizer): Set inner_loop dynamically — true for single mode, false for fan-out/independent (parallel branches). Single-task roles (profiler, strategist, benchmarker, reviewer): Set inner_loop: false.

User Commands

| Command | Action | |---------|--------| | check / status | Output execution status graph (branch-grouped), no advancement | | resume / continue | Check worker states, advance next step | | revise <TASK-ID> [feedback] | Create revision task + cascade downstream (scoped to branch) | | feedback <text> | Analyze feedback impact, create targeted revision chain | | recheck | Re-run quality check | | improve [dimension] | Auto-improve weakest dimension |

Completion Action

When the pipeline completes:

AskUserQuestion({
  questions: [{
    question: "Team pipeline complete. What would you like to do?",
    header: "Completion",
    multiSelect: false,
    options: [
      { label: "Archive & Clean (Recommended)", description: "Archive session, clean up tasks and team resources" },
      { label: "Keep Active", description: "Keep session active for follow-up work or inspection" },
      { label: "Export Results", description: "Export deliverables to a specified location, then clean" }
    ]
  }]
})

Error Handling

| Scenario | Resolution | |----------|------------| | Unknown --role value | Error with role registry list | | Role file not found | Error with expected path (roles/{name}/role.md) | | Profiling tool not available | Fallback to static analysis methods | | Benchmark regression detected | Auto-create FIX task with regression details | | Review-fix cycle exceeds 3 iterations | Escalate to user | | One branch IMPL fails | Mark that branch failed, other branches continue | | Fast-advance conflict | Coordinator reconciles on next callback | | Completion action fails | Default to Keep Active |
