Orchestrator Skill

Orchestrates the entire AIDA pipeline using Task tool for multi-agent delegation.

Overview

Manages 5-phase workflow and delegates work to Leader/Player subagents via Task tool. Implements the Conductor/Leader/Player pattern.

Task Tool Patterns

Launching a Leader

Parameter	Value
description	"Launch [leader-name] for [phase]"
subagent_type	"general-purpose"
run_in_background	true or false
prompt	Leader instructions

Leader-Spec Launch

Task tool parameters:
- description: "Leader-Spec: phases 1-4"
- subagent_type: "general-purpose"
- run_in_background: true
- prompt: |
    You are AIDA Leader-Spec.
    Read: agents/leader-spec.md
    Execute phases 1-4.
    Spawn players with Task tool (model: haiku).
    Output to: .aida/specs/

Leader-Impl Launch

Task tool parameters:
- description: "Leader-Impl: TDD implementation"
- subagent_type: "general-purpose"
- run_in_background: true
- prompt: |
    You are AIDA Leader-Impl.
    Read: agents/leader-impl.md
    Read specs from: .aida/specs/
    Spawn TDD players with Task tool (model: haiku).
    Output to: ./[PROJECT]/

Player Launch (from Leader)

Task tool parameters:
- description: "Player: [task description]"
- subagent_type: "general-purpose"
- model: "haiku"
- run_in_background: true (parallel) or false (sequential)
- prompt: |
    You are AIDA Player.
    Read: agents/player.md
    Task: [TASK_DESCRIPTION]
    Output: [OUTPUT_PATH]

Workflow (5 Phases)

Session Management

Directory Structure

.aida/
  state/
    session.json           # Session state
  checkpoints/             # Phase completion snapshots
  artifacts/
    requirements/          # Requirements output
    designs/               # Design output
  tasks/                   # Task assignments

  specs/                   # Final specifications
  kanban.md                # Project kanban board

session.json

{
  "session_id": "uuid-xxxx",
  "created_at": "ISO8601",
  "updated_at": "ISO8601",
  "phase": 3,
  "phase_name": "alignment",
  "user_request": "...",
  "project_name": "...",
  "leaders": {
    "spec": "running",

    "4": { "status": "pending" },
    "5": { "status": "pending" }
  }
}

Commands Integration

/aida:start

1. Initialize session
2. Launch leader-spec via Task tool
3. Monitor progress

/aida:work

1. Read session state
2. Determine current phase
3. Launch appropriate leader via Task tool

/aida:pipeline

1. Initialize session
2. Launch leader-spec (wait for completion)
3. Launch leader-impl (wait for completion)
4. Report final results

Parallel Execution

Leaders can spawn multiple players in parallel:

[Leader-Spec]
    |
    +-- Task tool (run_in_background: true) --> Player 1
    +-- Task tool (run_in_background: true) --> Player 2
    +-- Task tool (run_in_background: true) --> Player 3
    |
    +-- Wait for all players
    |
    +-- Integrate outputs

Context Optimization

Pass only necessary context between phases:

Phase 1 -> Phase 2:
  Pass: architecture_summary
  Skip: full conversation

Phase 4 -> Phase 5:
  Pass: .aida/specs/ paths
  Skip: intermediate details

Kanban Integration

Update .aida/kanban.md after each phase:

# Project: [PROJECT_NAME]

## Session: [SESSION_ID]

## Phases
- [x] Phase 1: Extraction (completed)
- [x] Phase 2: Structure (completed)
- [ ] Phase 3: Alignment (in progress)
- [ ] Phase 4: Verification (pending)
- [ ] Phase 5: Implementation (pending)
