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	STRATEGY-*	false
optimizer	roles/optimizer/role.md	IMPL-, FIX-	true
benchmarker	roles/benchmarker/role.md	BENCH-*	false
reviewer	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

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
