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

+---------------------------------------------------+
|  Skill(skill="team-executor")                      |
|  args="--session=<path>" [REQUIRED]                |
+-------------------+-------------------------------+
                    | Session Validation
         +---- --session valid? ----+
         | NO                       | YES
         v                          v
    Error immediately          Orchestration Mode
    (no session)               -> executor
                                    |
                    +-------+-------+-------+

                 [team-worker agents loaded from session role-specs]

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

Scenario	Action
No --session	ERROR immediately
--session invalid	ERROR with specific reason
Valid session	Orchestration Mode -> executor

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

User Commands (wake paused executor):

Command	Action
check / status	Output execution status graph, no advancement
resume / continue	Check worker states, advance next step

---

Role Registry

Role	File	Type
executor	roles/executor/role.md	built-in orchestrator
(dynamic)	<session>/role-specs/<role-name>.md	loaded from session

---

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>

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" }
    ]
  }]
})

Action Handlers

Choice	Steps
Archive & Clean	Update session status="completed" -> TeamDelete -> output final summary with artifact paths
Keep Active	Update session status="paused" -> output: "Resume with: Skill(skill='team-executor', args='--session=')"
Export Results	AskUserQuestion(target path) -> copy artifacts to target -> Archive & Clean

---

Cadence Control

Beat model: Event-driven, each beat = executor wake -> process -> spawn -> STOP.

Beat Cycle (single beat)
======================================================================
  Event                   Executor                 Workers
----------------------------------------------------------------------
  callback/resume --> +- handleCallback -+
                      |  mark completed   |
                      |  check pipeline   |
                      +- handleSpawnNext -+
                      |  find ready tasks |
                      |  spawn workers ---+--> [team-worker A] Phase 1-5
                      |  (parallel OK)  --+--> [team-worker B] Phase 1-5
                      +- STOP (idle) -----+         |
                                                     |
  callback <-----------------------------------------+
  (next beat)              SendMessage + TaskUpdate(completed)
======================================================================

  Fast-Advance (skips executor for simple linear successors)
======================================================================
  [Worker A] Phase 5 complete
    +- 1 ready task? simple successor? --> spawn team-worker B directly
    +- complex case? --> SendMessage to executor
======================================================================

Integration with team-coordinate

Scenario	Skill
New task, no session	team-coordinate
Existing session, resume execution	team-executor
Session needs new roles	team-coordinate (with resume)
Pure execution, no analysis	team-executor

---

Error Handling

Scenario	Resolution
No --session provided	ERROR immediately with usage message
Session directory not found	ERROR with path, suggest checking path
team-session.json missing	ERROR, session incomplete, suggest re-run team-coordinate
task-analysis.json missing	ERROR, session incomplete, suggest re-run team-coordinate
No role-specs in session	ERROR, session incomplete, suggest re-run team-coordinate
Role-spec file not found	ERROR with expected path
capability_gap reported	Warn only, cannot generate new role-specs
Fast-advance spawns wrong task	Executor reconciles on next callback
Completion action fails	Default to Keep Active, log warning
