feature-implementation

End-to-end workflow for a feature-implementation tagged item — the feature container that holds the specification, plan, and holistic review. Child work items under this container use the feature-task tag with lighter gates (task-scope instead of full specification, task-level review without /simplify).

Covers all three phases (queue → work → review) with gate-enforced notes at each transition.

Usage: /feature-implementation [item-uuid]

• If item-uuid is provided: load the existing item and resume from its current phase
• If omitted: create a new item and start from the beginning

---

Phase 0 — Setup

If an item UUID was provided, call:

get_context(itemId="<uuid>")

Check canAdvance and missingRequiredNotes to determine which phase the item is in, then jump to the appropriate phase below.

If no UUID was provided, create the item:

manage_items(
  operation="create",
  items=[{ title: "<feature title>", tags: "feature-implementation", priority: "medium" }]
)

Note the returned UUID and expectedNotes list. Confirm the item is in queue role, then continue to Phase 1.

---

Phase 1 — Queue: Define Requirements and Design

Goal: Fill the two required queue-phase notes before advancing to work.

1a. Fill requirements

Use manage_notes to upsert the requirements note:

manage_notes(
  operation="upsert",
  notes=[{
    itemId: "<uuid>",
    key: "requirements",
    role: "queue",
    body: "<content>"
  }]
)

What to write: The problem this solves. Who benefits. 2–5 concrete acceptance criteria that define done. Reference any existing observations or bug items that motivated this feature.

1b. Fill design

manage_notes(
  operation="upsert",
  notes=[{
    itemId: "<uuid>",
    key: "design",
    role: "queue",
    body: "<content>"
  }]
)

What to write: Chosen approach. Alternatives considered and why they were ruled out. Key risks or constraints (schema migrations, tight coupling areas, ORM quirks, test isolation issues). Reference specific files and classes that will be touched.

1c. Enter plan mode

After filling both notes, use EnterPlanMode to explore the codebase and produce a concrete implementation plan. The pre-plan hook will inject additional guidance.

When the plan is approved, post-plan hook fires — proceed directly to Phase 2 without pausing.

1d. Advance to work

advance_item(transitions=[{ itemId: "<uuid>", trigger: "start" }])

Gate check: both requirements and design must be filled. If gate rejects, fill the missing notes and retry.

Confirm newRole: "work" in the response before dispatching implementation subagents.

---

Phase 2 — Work: Implement and Document

Goal: Delegate implementation, then fill work-phase notes before advancing to review.

2a. Materialize any child items

If the feature has sub-tasks, create them now using create_work_tree with the feature UUID as parentId. Dispatch implementation subagents with each child item UUID.

Each subagent must:

• Call advance_item(trigger="start") on their item to enter work phase
• Fill work-phase notes following the JIT progression loop (the subagent-start hook provides guidance via guidancePointer and skillPointer)
• Return to the orchestrator — do NOT call advance_item again. The orchestrator handles all further transitions.

2b. Fill implementation-notes

After implementation agents return:

manage_notes(
  operation="upsert",
  notes=[{
    itemId: "<uuid>",
    key: "implementation-notes",
    role: "work",
    body: "<content>"
  }]
)

What to write: Key decisions made during implementation. Deviations from the design note. Any surprises (wrong class names, API differences, test isolation issues). Files changed with line counts. If an observation was fixed, reference its item ID.

2c. Fill test-results

manage_notes(
  operation="upsert",
  notes=[{
    itemId: "<uuid>",
    key: "test-results",
    role: "work",
    body: "<content>"
  }]
)

What to write: Run ./gradlew :current:test. Report total count and any failures. List new test classes or cases added. If root-module tests were affected, report those too.

2d. Advance to review

advance_item(transitions=[{ itemId: "<uuid>", trigger: "start" }])

Gate check: both implementation-notes and test-results must be filled. Confirm newRole: "review" in the response.

---

Phase 3 — Review: Deploy and Verify

Goal: Deploy, verify in the running MCP server, then close the item.

3a. Deploy to Docker (if needed)

Run /deploy_to_docker --current to rebuild the image with the new code. Reconnect MCP after deploy: /mcp.

3b. Smoke test the change

Exercise the new capability via MCP tool calls. Confirm it behaves as described in the requirements note acceptance criteria.

3c. Fill deploy-notes (optional)

manage_notes(
  operation="upsert",
  notes=[{
    itemId: "<uuid>",
    key: "deploy-notes",
    role: "review",
    body: "<content>"
  }]
)

What to write: Whether a Docker rebuild was done and what image tag was used. Plugin version bump (if any). MCP reconnect required. Any smoke test results.

3d. Close the item

advance_item(transitions=[{ itemId: "<uuid>", trigger: "start", summary: "<one-line summary>" }])

Confirm newRole: "terminal". Run get_context() health check to verify no stalled items.

Quick Reference

Phase	Required notes	Advance trigger
queue	requirements, design	start → work
work	implementation-notes, test-results	start → review
review	(none required)	start → terminal

Gate error pattern: "required notes not filled for <phase> phase: <keys>" → Fill the listed notes, then retry advance_item.
