description	Multi-agent management workflow — task delegation, progress monitoring, quality verification with regression testing, feedback delivery, and cross-review orchestration. Use this skill when coordinating multiple agents on a shared task, monitoring delegated work, ensuring quality across agent outputs, or implementing a multi-phase plan (3+ phases or 10+ file changes).

Synapse Manager

Orchestrate multi-agent work with structured delegation, monitoring, and quality gates.

Task Board Rule

Every delegation MUST have a matching task board entry.

Before sending work to any agent via synapse send, you must:

1. synapse tasks create "<task>" -d "<description>" — register the work unit
2. synapse tasks assign <id> <agent> — record ownership
3. Only then synapse send <agent> "..." --force

Task board is the team contract — it makes ownership, blocking, and completion state visible to every agent. TodoList is for your personal micro-step tracking only.

When to Use

• Coordinating 2+ agents on related subtasks
• Monitoring progress of delegated work
• Verifying agent outputs (tests, file changes, integration)
• Sending targeted feedback with error details and fix guidance
• Orchestrating cross-review between agents
• Implementing a multi-phase plan (3+ phases or 10+ file changes)
• Planning agent assignment for multi-file changes

Workflow (7 Steps)

Step 1: Plan, Spec, and Setup

New tests first. Follow this order for every implementation task: create tests -> present/confirm spec -> then implement.

Edit plugins/synapse-a2a/skills/ first, then sync generated copies with sync-plugin-skills.

Task board is the default coordination surface for manager-led work. Create or refresh task board entries before delegation starts so ownership, blocking, and completion state are visible to the whole team.

Check existing agents before spawning — reuse is faster (avoids startup overhead, instruction injection, and readiness wait):

synapse list

Review WORKING_DIR, ROLE, STATUS, TYPE. Only READY agents can accept work immediately.

Spawn only when no existing agent can handle the task:

synapse spawn claude --worktree --name Impl --role "feature implementation"
synapse spawn gemini -w --name Tester --role "test writer"

Cross-model spawning (Claude spawns Gemini, etc.) provides diverse strengths and distributes token usage across providers, avoiding rate limits.

Wait for readiness using the helper script. Resolve it from the skill root so the command works from any working directory, whether you are in the plugin source or a synced copy:

cd plugins/synapse-a2a/skills/synapse-manager
scripts/wait_ready.sh Impl 30
scripts/wait_ready.sh Tester 30

# Synced copy example
cd .agents/skills/synapse-manager
scripts/wait_ready.sh Impl 30

See references/auto-approve-flags.md for per-CLI permission skip flags.

Step 2: Create Tests and Confirm the Spec

Task board makes work visible to the entire team, prevents duplication, and ensures implementation is blocked on confirmed tests/spec:

synapse tasks create "Write auth tests" \
  -d "Create tests/spec for valid login, invalid credentials, token expiry, refresh flow" \
  --priority 5
# Returns: 3f2a1b4c (displayed prefix of a UUID such as 3f2a1b4c-1111-2222-3333-444444444444)

synapse tasks create "Implement auth module" \
  -d "Add OAuth2 with JWT in synapse/auth.py after tests/spec are confirmed. Follow patterns in synapse/server.py." \
  --priority 4 \
  --blocked-by 3f2a1b4c
# Returns: 7a9d2e10 (displayed prefix of a UUID such as 7a9d2e10-5555-6666-7777-888888888888)

synapse tasks create stores a full UUID and prints its first 8 characters. Use that prefix (or the full UUID) for --blocked-by, synapse tasks assign, and synapse tasks complete. In practice that means the implementation task should use a dependency like --blocked-by 3f2a1b4c, where 3f2a1b4c is the created test task's UUID prefix. Conceptually this is still "implementation --blocked-by tests"; the concrete value just needs to be the created test task's UUID prefix.

Assign the test/spec task and confirm scope before implementation starts:

TESTS_ID=3f2a1b4c
IMPL_ID=7a9d2e10

synapse tasks assign "$TESTS_ID" Tester
synapse send Tester "Write the tests first and confirm the spec for task $TESTS_ID (Write auth tests).
- Cover valid login, invalid credentials, token expiry, refresh flow
- Report any scope gaps before implementation starts" --attach synapse/server.py --force --wait

Use --attach to send reference files the agent should study. Use --wait while confirming tests/spec, then --silent or --notify once execution is unblocked.

Default expectation:

• synapse tasks create for each meaningful work unit
• synapse tasks assign when ownership changes
• synapse tasks complete when verification passes
• synapse tasks fail when blocked or broken, with a reason the next agent can act on

Step 3: Delegate Implementation and Monitor

After tests/spec are confirmed, assign the implementation task:

synapse tasks assign "$IMPL_ID" Impl
synapse send Impl "Implement auth module — tests/spec are confirmed in task $TESTS_ID (Write auth tests).
- Add OAuth2 flow in synapse/auth.py
- Follow existing patterns" --attach synapse/server.py --force --silent

Shortcut — task-linked send: For simple delegations, use --task / -T to create, assign, and send in one step (auto-claim on receive, auto-complete on finalize):

synapse send Impl "Implement auth module" --task --attach synapse/server.py --force --silent

synapse list                              # Live status (auto-updates)
synapse tasks list                        # Task board progress and dependencies
synapse history list --agent Impl         # Completed work

Or use the aggregation script:

cd plugins/synapse-a2a/skills/synapse-manager && scripts/check_team_status.sh

If an agent stays PROCESSING >5 min, send an interrupt:

synapse interrupt Impl "Status update — what is your current progress?" --force

Step 4: Approve Plans

synapse approve <task_id>
synapse reject <task_id> --reason "Use refresh tokens instead of long-lived JWTs."

Plan Card workflow — for structured plans posted to Canvas:

# Accept a plan card and register its steps as task board tasks
synapse tasks accept-plan <plan_id>

# Sync task board progress back to the plan card
synapse tasks sync-plan <plan_id>

Update task board after decision:

# After approve — keep the approved plan moving via assignment/delegation.
# The task board changes at lifecycle checkpoints (assign, complete, fail, reopen).

# After reject — mark for rework
synapse tasks reopen <task_id>

Step 5: Verify

Testing is the critical quality gate — start with the new tests/spec that were created up front, then run broader regression coverage because an agent's changes may break unrelated modules through import chains or shared state:

# New tests first (fast feedback)
pytest tests/test_auth.py -v

# Full regression (catches cross-module breakage)
pytest --tb=short -q

Regression triage — distinguish new breakage from pre-existing issues:

cd plugins/synapse-a2a/skills/synapse-manager && scripts/regression_triage.sh tests/test_failing_module.py -v

• Exit 0 = REGRESSION (your changes broke it) → proceed to Step 6
• Exit 1 = PRE-EXISTING (already broken) → note it and continue

Update task board:

synapse tasks complete <task_id>
synapse tasks fail <task_id> --reason "test_refresh_token fails — TypeError on line 42"

Step 6: Feedback

Concrete, actionable feedback saves iteration cycles:

synapse send Impl "Issues found — please fix:

1. FAILING TEST: test_token_expiry (tests/test_auth.py)
   ERROR: TypeError: cannot unpack non-iterable NoneType object
   FIX: Add None guard at the top of validate_token()

2. REGRESSION: test_existing_endpoint broke
   ERROR: expected 200, got 401
   CAUSE: auth middleware intercepts all routes
   FIX: Exclude health-check endpoints from auth" --force --silent

Save patterns for the team:

synapse memory save auth-middleware-pattern \
  "Auth middleware must exclude /status and /.well-known/* endpoints" \
  --tags auth,middleware --notify

After sending feedback, reopen the task and return to Step 3 (Monitor):

synapse tasks reopen <task_id>

Step 7: Review & Wrap-up

Cross-review catches blind spots — each agent reviews the other's work:

synapse send Tester "Review implementation. Focus on: correctness, edge cases" --force \
  --attach synapse/auth.py --wait
synapse send Impl "Review test coverage. Focus on: missing cases, assertion quality" --force \
  --attach tests/test_auth.py --wait

Final verification and cleanup:

pytest --tb=short -q                      # All tests pass
synapse tasks list                        # Confirm the UUID prefixes before completion
synapse tasks complete "$TESTS_ID"
synapse tasks complete "$IMPL_ID"
synapse kill Impl -f && synapse kill Tester -f
synapse list                              # Verify cleanup
synapse tasks purge --status completed    # Clean up finished tasks
synapse tasks purge --older-than 7d      # Clean up old tasks
synapse tasks purge --dry-run            # Preview what would be deleted

Killing spawned agents frees ports, memory, and PTY sessions. Orphaned agents may accidentally accept future tasks intended for other agents.
