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

Pre-load (coordinator, before dispatch)

1. **Codebase docs**: If `.workflow/codebase/ARCHITECTURE.md` exists, read for module boundaries 2. **Specs (coding)**: `maestro load --type spec --category coding` — load coding constraints as shared context 3. **Wiki knowledge**: `maestro search "performance optimization profiling" --json` — top 5 entries as prior context 4. All optional — proceed without if unavailable

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**: `{run_dir}/work/team/`
• **Team name**: `perf-opt`
• **CLI tools**: `maestro delegate --mode analysis` (read-only), `maestro delegate --mode write` (modifications)
• **Message bus**: `mcp__maestro__team_msg(session_id=<run-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: {run_dir}/work/team
session_id: <run-id>
team_name: perf-opt
requirement: <task-description>
inner_loop: <true|false>

## Progress Milestones
session_id: <run-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 |
