name: status-progression description: Navigate role transitions for MCP work items using advance_item. Shows current role, gate status, required notes, and the correct trigger to use. Use when a user says "advance this item", "move to work", "start this task", "complete this item", "what's the next status", "why can't I advance", "unblock this", "cancel this item", or "check gate status". argument-hint: "[optional: item UUID or title to look up]"

Status Progression — Current (v3)

Guides role transitions for a WorkItem: identify the item, check gate status, fill missing notes, and advance. Handles all triggers including block, resume, and cancel.

Step 1: Identify the Item

Determine which item to work with before calling anything else.

If $ARGUMENTS looks like a UUID (8-4-4-4-12 hex pattern), use it directly as the item ID in Step 2.

If $ARGUMENTS is a text string (title fragment or keyword), search for it:

query_items(operation="search", query="$ARGUMENTS", limit=5)

If the search returns exactly one result, use that item ID. If it returns multiple results, present them to the user via AskUserQuestion:

◆ Multiple items matched "$ARGUMENTS" — which did you mean?
  1. "Implement authentication module" (work) — uuid-1
  2. "Implement caching layer" (queue) — uuid-2
  3. "Implement rate limiting" (queue) — uuid-3

If $ARGUMENTS is empty, ask via AskUserQuestion: "Which item do you want to advance? Provide a UUID or title fragment."

Step 2: Check Current State

Once you have the item ID, call:

get_context(itemId="<item-uuid>")

Parse the response and display a status card. Use this format:

◉ "Implement authentication module"
  Role:     work
  Gate:     ⊘ blocked — 2 required notes missing
  Missing:  implementation-notes (work, required)
            test-results (work, required)
  Guidance: "Describe what was implemented, which files changed, and why
             the approach was chosen..."

◉ "Design API schema"
  Role:     queue
  Gate:     ✓ open — all required notes filled (or no schema)
  Next:     advance_item(trigger="start") → work

Fields to surface from get_context response:

If the item has no schema (no tags matching a schema key), noteSchema will be empty and the gate is always open.

Step 3: Fill Missing Notes (if Gated)

If gateStatus.canAdvance = false, the item cannot advance until required notes are filled.

For each missing note, check whether its content can be inferred from the conversation context. If yes, fill it directly. If not, ask the user what to capture.

Use guidancePointer to prompt the user — it contains the guidance text for the first unfilled required note in the current phase. Only one guidancePointer is returned — for the first unfilled required note. See schema entries list for all unfilled notes.

Fill notes with:

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

After filling, re-check gate status:

get_context(itemId="<uuid>")

Confirm gateStatus.canAdvance = true before proceeding to Step 4. If notes are still missing after the upsert, show the updated status card and repeat for any remaining gaps.

Step 4: Advance the Item

With the gate open, call advance_item using the appropriate trigger (see Trigger Reference below):

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

Parse the response and report the transition result:

✓ Advanced: queue → work
  ↳ Cascade: "Feature: Auth System" also moved queue → work
  ↳ Unblocked: "Write integration tests" (was waiting on this item)
  ↳ Next phase notes:
      implementation-notes (work, required)
      test-results (work, required)

Fields to check in the advance response:

If cascadeEvents is empty, omit the cascade line. If unblockedItems is empty, omit the unblocked line. If expectedNotes is empty or absent (no schema), omit the next phase notes line.

Trigger Reference

Choose the trigger based on the item's current role and the desired outcome:

Important notes:

• start checks gates for the current phase only — missing notes for the current phase block the transition; future-phase notes are not checked
• complete checks gates across all phases — all required notes across queue, work, and review must be filled before terminal is reached; because it jumps directly to terminal, skipping intermediate phases, all prior phase notes are verified up front
• cancel does not check gates — items can be cancelled at any time regardless of missing notes; statusLabel is set to "cancelled"; allowing cleanup regardless of state is intentional so a blocked or incomplete item can always be abandoned
• block and resume are a paired workflow — block saves previousRole internally so resume always returns to the exact role before blocking; do not use start to resume a blocked item; this pairing is what guarantees resume returns to exact pre-block role rather than restarting from queue
• When an item reaches TERMINAL, any items that had a BLOCKS dependency on it become unblocked — they appear in unblockedItems in the advance response
• Cascade events: the first child to start from queue triggers its parent to cascade queue → work; the last child to reach terminal triggers its parent to cascade → terminal

Troubleshooting

Problem: advance_item fails with "required notes not filled"

Cause: The current phase has required notes that have not been upserted yet. Gate enforcement runs before the transition executes.

Solution: Call get_context(itemId="<uuid>") to see exactly which notes are missing. Fill each one with manage_notes(operation="upsert"), then retry advance_item.

Problem: Item cannot advance — it is blocked by a dependency

Cause: Another item has a BLOCKS edge pointing to this item, and that blocking item has not yet reached terminal role.

Solution: Find the blocker:

query_dependencies(itemId="<uuid>", direction="incoming", includeItemInfo=true)

Identify the blocking item (role will be non-terminal). Advance the blocking item to terminal first. When it completes, the current item appears in unblockedItems.

Problem: Item is in BLOCKED role and start fails

Cause: The item is in the BLOCKED role (was explicitly blocked with trigger: "block"). The start trigger is not valid from BLOCKED — it is only valid from QUEUE, WORK, or REVIEW.

Solution: Use trigger: "resume" to return the item to its previous role:

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

After resuming, check get_context and then advance normally with start if the gate is open.

Problem: Want to skip the review phase and go directly to terminal

Cause: The item is in WORK role and has a review-phase schema, but verification is already done or not applicable.

Solution: Use trigger: "complete" instead of start. This jumps from any non-terminal role directly to TERMINAL, but it checks ALL required notes across all phases first:

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

If any required notes across queue, work, or review phases are unfilled, the gate will block this call and list the missing notes. Fill them, then retry.

Problem: Parent item cascaded unexpectedly

Cause: Cascade is by design. When the first child of a container starts (queue → work), the container cascades to work automatically. When the last child reaches terminal, the container cascades to terminal automatically.

Solution: This is expected behavior — no action needed. Check cascadeEvents in the advance_item response to see exactly which ancestors transitioned and why. If the cascade is unwanted, you can manually adjust the parent's role using advance_item with trigger: "block" or trigger: "complete" depending on the desired state.

Problem: advance_item returns "no valid transition" or "item already terminal"

Cause: The item is already in TERMINAL role (completed or cancelled). Terminal is a final state — no triggers are valid from terminal.

Solution: The item cannot be advanced further. If the item was completed in error, you would need to create a new item. To verify the item's current state:

query_items(operation="get", id="<uuid>")

Check the role field. If role = "terminal", the item's lifecycle is complete.

Examples

Example 1: Simple Flow — No Schema

For items with no matching note schema, there are no gates. Items flow freely through roles.

Step 1: Check state

get_context(itemId="abc-123")

Response shows role: "queue", gateStatus.canAdvance: true, noteSchema: [].

Status card:

◉ "Refactor database connection pool"
  Role:  queue
  Gate:  ✓ open (no schema)
  Next:  advance_item(trigger="start") → work

Step 2: Start work

advance_item(transitions=[{ itemId: "abc-123", trigger: "start" }])

Result:

✓ Advanced: queue → work

Step 3: Complete work (skip review)

After the refactor is done, complete directly:

advance_item(transitions=[{ itemId: "abc-123", trigger: "complete" }])

Result:

✓ Advanced: work → terminal

No gates — no notes required. Items without a schema move freely at any time using any valid trigger.

Example 2: Gated Flow — Item Has feature-implementation Tag

Items tagged feature-implementation have a schema with required notes at each phase. The gate blocks advancement until notes are filled.

Step 1: Check state

get_context(itemId="def-456")

Response shows role: "queue", gateStatus.canAdvance: false, missing: ["requirements"].

Status card:

◉ "Add OAuth2 login flow"
  Role:     queue
  Gate:     ⊘ blocked — 1 required note missing
  Missing:  requirements (queue, required)
  Guidance: "Document the acceptance criteria and scope of this feature.
             Include: what the feature does, what it does not do, and
             the definition of done."

Step 2: Fill the missing note

Ask the user (or extract from conversation context) what the requirements are, then upsert:

manage_notes(
  operation="upsert",
  notes=[{
    itemId: "def-456",
    key: "requirements",
    role: "queue",
    body: "Implement OAuth2 login via GitHub and Google providers. Users should
           be redirected to provider, authenticated, and returned to the app
           with a session token. Out of scope: social sign-up flow, profile
           linking. Done when: login button visible on /login, both providers
           work in staging, session persists across page reload."
  }]
)

Step 3: Re-check gate

get_context(itemId="def-456")

Updated status card:

◉ "Add OAuth2 login flow"
  Role:  queue
  Gate:  ✓ open — all queue notes filled
  Next:  advance_item(trigger="start") → work

Step 4: Advance to work

advance_item(transitions=[{ itemId: "def-456", trigger: "start" }])

Result:

✓ Advanced: queue → work
  ↳ Next phase notes:
      implementation-notes (work, required)
      test-results (work, required)

The expectedNotes in the response shows what must be filled during the work phase before the next start will succeed. Fill these notes as implementation progresses, then call advance_item(trigger="start") again to move to review or terminal.
