Work Reporting:

Acceptance Criteria:

Session (sub-agents only — main agent skips these):

Sub-agents: always pass sessionUuid to chorus_update_task and chorus_report_work for attribution. Main agent / Team Lead: call these tools without sessionUuid — no session needed.

Shared tools (checkin, query, comment, search, notifications): see /chorus

Workflow

Step 1: Check In

chorus_checkin()

Review your persona, current assignments, and pending work counts.

Step 1.5: Get Your Session (Sub-Agents Only)

Skip if you are the main agent or Team Lead.

If you are a sub-agent, the Chorus Plugin automatically creates your session — look for a "Chorus Session" section in your system reminders containing your sessionUuid. Keep it for all task operations.

Step 2: Find Work

chorus_get_available_tasks({ projectUuid: "<project-uuid>" })

Or check existing assignments:

chorus_get_my_assignments()

Step 3: Claim a Task

chorus_get_task({ taskUuid: "<task-uuid>" })  # Review first
chorus_claim_task({ taskUuid: "<task-uuid>" })

Check: description, acceptance criteria, priority, story points, related proposal/documents.

Step 4: Gather Context

Each task and proposal includes a commentCount field — use it to decide which entities have discussions worth reading.

1. Read the task and identify dependencies:

   chorus_get_task({ taskUuid: "<task-uuid>" })
   

   Pay attention to dependsOn (upstream tasks) and commentCount.

2. Read task comments (contains previous work reports, progress, feedback):

   chorus_get_comments({ targetType: "task", targetUuid: "<task-uuid>" })
   

3. Review upstream dependency tasks — your work likely builds on theirs:

   chorus_get_task({ taskUuid: "<dependency-task-uuid>" })
   chorus_get_comments({ targetType: "task", targetUuid: "<dependency-task-uuid>" })
   

   Look for: files created, API contracts, interfaces, trade-offs.

4. Read the originating proposal for design intent:

   chorus_get_proposal({ proposalUuid: "<proposal-uuid>" })
   

5. Read project documents (PRD, tech design, ADR):

   chorus_get_documents({ projectUuid: "<project-uuid>" })
   

Step 5: Start Working

Sub-agent: checkin to the task first:

chorus_session_checkin_task({ sessionUuid: "<session-uuid>", taskUuid: "<task-uuid>" })

Then mark as in-progress:

# Sub-agent:
chorus_update_task({ taskUuid: "<task-uuid>", status: "in_progress", sessionUuid: "<session-uuid>" })

# Main agent:
chorus_update_task({ taskUuid: "<task-uuid>", status: "in_progress" })

Dependency enforcement: If this task has unresolved dependencies (dependsOn tasks not in done or closed), the call will be rejected with detailed blocker info. Use chorus_get_unblocked_tasks to find tasks you can start now.

Step 6: Report Progress

Report periodically with chorus_report_work. Include:

• What was completed
• Files created or modified
• Git commits and PRs
• Current status / remaining work
• Blockers or questions

chorus_report_work({
  taskUuid: "<task-uuid>",
  report: "Progress:\n- Created src/services/auth.service.ts\n- Commit: abc1234\n- Remaining: unit tests",
  sessionUuid: "<session-uuid>"
})

Report with status update when complete:

chorus_report_work({
  taskUuid: "<task-uuid>",
  report: "All implementation complete:\n- Files: ...\n- PR: https://github.com/org/repo/pull/42\n- All tests passing",
  status: "to_verify",
  sessionUuid: "<session-uuid>"
})

Step 7: Self-Check Acceptance Criteria

Before submitting, check structured acceptance criteria:

task = chorus_get_task({ taskUuid: "<task-uuid>" })

# If task.acceptanceCriteriaItems is non-empty:
chorus_report_criteria_self_check({
  taskUuid: "<task-uuid>",
  criteria: [
    { uuid: "<criterion-uuid>", devStatus: "passed", devEvidence: "Unit tests cover this" },
    { uuid: "<criterion-uuid>", devStatus: "passed", devEvidence: "Verified manually" }
  ]
})

For required criteria, keep working until you can self-check as passed. Only use failed for optional criteria that are out of scope.

Step 8: Submit for Verification

Sub-agents — checkout first:

chorus_session_checkout_task({ sessionUuid: "<session-uuid>", taskUuid: "<task-uuid>" })

Then submit:

chorus_submit_for_verify({
  taskUuid: "<task-uuid>",
  summary: "Implemented auth feature:\n- Added login/logout endpoints\n- JWT middleware\n- 95% test coverage\n- All AC self-checked (3/3 passed)"
})

to_verify does NOT unblock downstream tasks — only done (after admin verification) does.

Review Agent: After chorus_submit_for_verify, the Chorus plugin's PostToolUse hook will suggest spawning chorus:task-reviewer — an independent, read-only review agent. Follow the suggestion to get an adversarial review before admin verification. The reviewer posts a VERDICT comment on the task. Its result is advisory (does not block verification).

Step 9: Handle Review Feedback

If reopened (verification failed), all acceptance criteria are reset to pending.

1. Check feedback:

   chorus_get_task({ taskUuid: "<task-uuid>" })
   chorus_get_comments({ targetType: "task", targetUuid: "<task-uuid>" })
   

2. Checkin again, fix issues, report fixes, resubmit.

Step 10: Task Complete

Once Admin verifies (status: done), move to the next available task (back to Step 2).

Session (Sub-Agents Only)

The Chorus Plugin fully automates session lifecycle — creation, heartbeat, and cleanup are all handled by hooks. Sub-agents only do 3 things manually:

1. chorus_session_checkin_task({ sessionUuid, taskUuid }) — before starting work
2. chorus_session_checkout_task({ sessionUuid, taskUuid }) — when done (recommended; plugin also auto-checkouts on exit)
3. Pass sessionUuid to chorus_update_task and chorus_report_work for attribution

Main agent / Team Lead: no session needed — call tools without sessionUuid.

Claude Code Agent Teams Integration

When using Claude Code's Agent Teams to run multiple sub-agents in parallel, Chorus provides full work observability.

Two-Layer Architecture

Team Lead Workflow

# 1. Check in and plan
chorus_checkin()
chorus_list_tasks({ projectUuid: "<project-uuid>" })

# 2. Create Claude Code team and spawn sub-agents
TeamCreate({ team_name: "feature-x" })

# Pass only task UUIDs — plugin auto-injects session workflow
Task({
  name: "frontend-worker",
  prompt: "Your Chorus task UUID: <task-uuid>\nProject UUID: <project-uuid>\n\nImplement..."
})

What the Team Lead prompt needs:

• Task UUID(s)
• NO session UUID, NO workflow boilerplate — plugin auto-injects everything

Sub-Agent Workflow

The plugin injects session UUID and workflow into the sub-agent's context automatically.

# 1. Checkin to task
chorus_session_checkin_task({ sessionUuid: "<my-session-uuid>", taskUuid: "<my-task-uuid>" })

# 2. Move to in_progress
chorus_update_task({ taskUuid: "<my-task-uuid>", status: "in_progress", sessionUuid: "<my-session-uuid>" })

# 3. Do work... code, test, commit...

# 4. Report progress
chorus_report_work({ taskUuid: "<my-task-uuid>", report: "...", sessionUuid: "<my-session-uuid>" })

# 5. Checkout and submit
chorus_session_checkout_task({ sessionUuid: "<my-session-uuid>", taskUuid: "<my-task-uuid>" })
chorus_submit_for_verify({ taskUuid: "<my-task-uuid>", summary: "..." })

# 6. Notify team lead
SendMessage({ type: "message", recipient: "team-lead", content: "Task complete" })

# DO NOT close session — plugin closes it automatically on exit

Handling Task Dependencies (DAG)

Server-side enforcement: chorus_update_task(status: "in_progress") rejects if any dependsOn task is not done or closed.

Wave-based execution (recommended):

1. chorus_get_unblocked_tasks — find ready tasks
2. Spawn sub-agents for Wave 1
3. Wait for to_verify, then verify each task (chorus_admin_verify_task → done)
4. chorus_get_unblocked_tasks — find newly unblocked tasks (Wave 2)
5. Repeat until all tasks done

Critical: to_verify does NOT resolve dependencies — only done or closed does. The Team Lead must verify tasks between waves.

Multiple Tasks Per Sub-Agent

A single sub-agent can work on multiple tasks sequentially:

Task({
  name: "full-stack-worker",
  prompt: "Your Chorus tasks (work in order):\n1. task-schema-uuid\n2. task-api-uuid (depends on #1)\n\nFor EACH task: checkin -> in_progress -> work -> report -> checkout -> submit_for_verify"
})

MCP Access for Sub-Agents

Sub-agents need MCP configured at project level (.mcp.json or .claude/settings.json). User-level config may not be accessible to sub-agents.

Troubleshooting

Work Report Best Practices

Good report (enables session continuity):

Implemented password reset flow:

Files created/modified:
- src/services/auth.service.ts (new)
- src/app/api/auth/reset/route.ts (new)
- tests/auth/reset.test.ts (new)

Git:
- Commit: a1b2c3d "feat: password reset flow"
- PR: https://github.com/org/repo/pull/15

Implementation details:
- POST /api/auth/reset-request: sends email with token
- Token expires after 1 hour, single-use
- Rate limiting: 3 requests/hour/email
- 12 new tests, all passing

Acceptance criteria:
- [x] User can request reset via email
- [x] Reset link expires after 1 hour
- [x] Rate limiting prevents abuse

Bad report: Done.

Tips

• Read task comments first — they contain previous work reports for session continuity
• Check upstream dependencies — read dependsOn tasks and their comments for interfaces/APIs
• Read the originating proposal — understand design rationale and task DAG
• Use commentCount — skip fetching comments on entities with count 0
• Report progress frequently — include file paths, commits, and PRs
• Write detailed submit summaries — Admin needs them to verify
• If blocked, add a comment and consider releasing the task
• One task at a time: finish or release before claiming another
• Use meaningful sub-agent names — they become Chorus session names

When to Release a Task

Release if:

• You can't complete it (missing knowledge, blocked)
• A higher-priority task needs attention
• You won't finish in a reasonable timeframe

chorus_release_task({ taskUuid: "<task-uuid>" })
chorus_add_comment({ targetType: "task", targetUuid: "<task-uuid>", content: "Releasing: reason..." })

Next

• After submitting for verification, an Admin reviews using /review
• For platform overview and shared tools, see /chorus
