Team Executor

Lightweight session execution skill: load session -> reconcile state -> spawn team-worker agents -> execute -> deliver. No analysis, no role generation -- only executes existing team-coordinate sessions.

Architecture

Session Validation (BEFORE routing)

CRITICAL: Session validation MUST occur before any execution.

Parse Arguments

Extract from $ARGUMENTS:

• --session=<path>: Path to team-coordinate session folder (REQUIRED)

Validation Steps

1. Check --session provided:

   • If missing -> ERROR: "Session required. Usage: --session="

2. Validate session structure (see specs/session-schema.md):

   • Directory exists at path
   • team-session.json exists and valid JSON
   • task-analysis.json exists and valid JSON
   • role-specs/ directory has at least one .md file
   • Each role in team-session.json#roles has corresponding .md file in role-specs/

3. Validation failure:

   • Report specific missing component
   • Suggest re-running team-coordinate or checking path

Role Router

This skill is executor-only. Workers do NOT invoke this skill -- they are spawned as team-worker agents directly.

Dispatch Logic

Orchestration Mode

Invocation: Skill(skill="team-executor", args="--session=<session-folder>")

Lifecycle:

Validate session
  -> executor Phase 0: Reconcile state (reset interrupted, detect orphans)
  -> executor Phase 1: Spawn first batch team-worker agents (background) -> STOP
  -> Worker executes -> SendMessage callback -> executor advances next step
  -> Loop until pipeline complete -> Phase 2 report + completion action

Executor Spawn Template

v2 Worker Spawn (all roles)

When executor spawns workers, use team-worker agent with role-spec path:

Agent({
  subagent_type: "team-worker",
  description: "Spawn <role> worker",
  team_name: <team-name>,
  name: "<role>",
  run_in_background: true,
  prompt: `## Role Assignment
role: <role>
role_spec: <session-folder>/role-specs/<role>.md
session: <session-folder>
session_id: <session-id>
team_name: <team-name>
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 to load Phase 2-4 domain instructions.`
})

---

Completion Action

When pipeline completes (all tasks done), executor presents an interactive choice:

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 team" },
      { label: "Keep Active", description: "Keep session for follow-up work" },
      { label: "Export Results", description: "Export deliverables to target directory, then clean" }
    ]
  }]
})
