agent-team

name: agent-team description: > Orchestrate a swarm of AI agents for parallel task execution using opencode sessions and tmux. One opencode server (with --port) hosts multiple sessions - one per agent. tmux windows provide visual monitoring via opencode attach. A standardized Python CLI (swarm.py) handles all inter-agent communication. Use when: (1) user asks to parallelize work across agents, (2) user says "spin up a team", "agent team", "swarm", "use multiple agents", (3) a task naturally decomposes into 2+ independent sub-tasks that benefit from parallel execution, (4) user says "start agents", "multi-agent", "work in parallel". IMPORTANT: This skill has two roles. If you receive a message containing [SWARM INIT], you are a WORKER - read references/worker-protocol.md immediately. Otherwise you are the LEADER orchestrator.

Agent Team

Role Detection

If your first message contains [SWARM INIT]: You are a WORKER worker. Read references/worker-protocol.md and follow it. Stop reading this file.

Otherwise: You are the LEADER orchestrator. Continue below.

Prerequisites

Ideally the user starts opencode with --port:

opencode --port 4096

If they did not, swarm.py init will automatically start opencode serve --port 4096 in a tmux window. This works but means the user's own TUI session is on a separate instance. For the best experience (user's TUI + workers on same server), recommend --port 4096.

Swarm CLI

All communication uses scripts/swarm.py in this skill directory. Resolve the path:

SWARM_CLI="$(dirname "$(dirname "$(readlink -f "$(which opencode)")")")/skills/agent-team/scripts/swarm.py"
# Or use the skill directory directly if known

Locate swarm.py by reading the skill directory from the skill loading context. The script requires only Python 3.10+ stdlib.

Leader Workflow

Phase 1: Decompose the Task

Analyze the user's request and break it into parallelizable sub-tasks.

Guidelines:

• Each sub-task should touch different files/modules when possible
• 2-4 workers is typical. More adds coordination overhead.
• Define clear boundaries: "worker-api owns src/api/, worker-ui owns src/components/"
• Identify dependencies: does worker-B need worker-A's output? If yes, note it in worker-B's task.

Output a plan table before proceeding:

Phase 2: Initialize the Swarm

python3 {SWARM_CLI} init \
  --port 4096 \
  --workdir {project_directory} \
  --worker "api:Implement REST API endpoints" \
  --worker "ui:Implement React frontend components"

This creates sessions, starts tmux windows with opencode attach, and writes state.

Phase 2.5: Register Leader Session

After init, find your own session ID and register it so workers can report back to you.

1. Use session_search to find your session (search for a unique string from this conversation):

   session_search(query="some unique phrase from the init output")
   

2. Register it:

   python3 {SWARM_CLI} set-leader --session {your_session_id}
   

This enables the report command - workers use it to send completion messages directly to you instead of broadcasting to all peers.

Phase 3: Send Initial Tasks

For each worker, compose an initial prompt. The FIRST line MUST be Load skill agent-team. - this triggers the worker to load this skill and read references/worker-protocol.md, which teaches it the full communication protocol (swarm.py commands, message conventions, peer interaction rules). Without this line, the worker will not know how to collaborate.

The prompt must include:

1. Load skill agent-team. (FIRST LINE - MANDATORY - triggers protocol loading)
2. The [SWARM INIT] marker (triggers worker role detection)
3. Identity block (name, role)
4. Swarm CLI path
5. Team roster (all peers with names and roles)
6. The actual task description
7. File scope boundaries

Template (use EXACTLY this structure):

Load skill agent-team.

[SWARM INIT]
Name: {worker_name}
Role: {role}
Swarm CLI: {SWARM_CLI}

Team:
- {peer_name} ({peer_role})
- {peer_name} ({peer_role})

Task:
{detailed task description}

Scope: Only modify files under {path}. Do not touch files outside your scope.
Dependencies: {any dependencies on other workers, or "none"}

IMPORTANT: Do NOT omit the Load skill agent-team. line. Without it, the worker will:

• Not know about swarm.py or how to communicate with peers
• Reject messages from other workers as "prompt injection"
• Not follow the completion protocol ([DONE] report to leader)

Send via:

python3 {SWARM_CLI} send --to {worker_name} --message "{initial_prompt}"

Send tasks to independent workers first, dependent workers after.

Phase 4: Monitor

Periodically check progress:

python3 {SWARM_CLI} status

When a worker's message count increases or you want details:

python3 {SWARM_CLI} read --from {worker_name} --last 3

Wait for a specific worker to finish:

python3 {SWARM_CLI} wait --for {worker_name} --timeout 300

Phase 5: Verify and Report

When all workers report [DONE] (via report to leader or detected idle via status):

1. Read each worker's final output:

   python3 {SWARM_CLI} read --from {worker_name} --last 5
   

2. Check for conflicts:

   • Run git status or git diff to see all changes
   • Verify no two workers modified the same file

3. Run project validation:

   • Build: run the project's build command
   • Test: run the project's test suite
   • Lint: run linters on changed files

4. If issues found, send fix instructions to the relevant worker:

   python3 {SWARM_CLI} send --to {worker_name} --message "Fix: {issue description}"
   

5. Report results to the user.

Phase 6: Teardown

python3 {SWARM_CLI} teardown

Or keep tmux alive for user inspection:

python3 {SWARM_CLI} teardown --keep-state

Handling Common Situations

Worker asks a question: The worker will block. Check status regularly. When you see a worker waiting, read their messages and respond via send.

Two workers need to coordinate: They can talk directly via the swarm CLI. But if they are stuck, intervene by reading both and relaying information.

Worker goes off-track: Abort and re-task:

# Via the opencode API directly:
curl -X POST http://localhost:{port}/session/{session_id}/abort
python3 {SWARM_CLI} send --to {worker_name} --message "Stop. New task: {corrected task}"

Build fails after all workers done: Read the error, determine which worker's code caused it, send a fix request to that worker only.
