description	Migrates an already-populated, unscoped Task Orchestrator database in place to the project-scoping convention — creates a project anchor root, re-parents existing work trees under it, and writes rootId back to config.yaml. Use when a user says: adopt project scope, migrate this database to project scoping, make this DB multi-project, project-scope this workspace, adopt existing database, or set up project scoping for an existing DB.

Adopt Project Scope — In-Place Migration to Project Scoping

Take an existing, unscoped database (many depth-0 roots, no project anchor) and migrate it in place to the project-scoping convention: one type=project root that owns the workspace's work trees, with its UUID written back to .taskorchestrator/config.yaml under a project: block. Global containers (retrospectives, observations) stay at depth 0; test artifacts are flagged for cleanup, never moved or deleted.

This is a destructive-by-execution skill: the EXECUTE step re-parents real items. It defaults to a dry run and never mutates anything without an explicit confirmation. The only thing it ever deletes is its own throwaway server-probe tree.

Non-goals: cross-DB consolidation (merging items from a second database); merging multiple existing project anchors into one; any server-side enforcement of scope. This skill adopts a single workspace's single database.

---

Step 0 — Parse Arguments

• Project name — the first non-flag token(s) in $ARGUMENTS. If absent, do not guess; ask for it in Step 3 (the dry-run plan) via AskUserQuestion before any mutation.
• --dry-run — if present, the skill stops after Step 3 (the plan) and performs zero mutations regardless of confirmation. The dry run is ALSO always rendered before execution even without the flag; the flag only forces an early exit.

---

Step 1 — Preflight (abort gates)

Run these checks in order. Each abort prints a clear, user-facing reason and stops.

1a — Already adopted?

Read .taskorchestrator/config.yaml. If it contains a project: block with a non-empty rootId:, the workspace is already scoped:

◆ Workspace already adopted — config.yaml already points at project root <rootId>.
  Nothing to do. Use /work-summary to inspect the existing project tree.

Stop. (If the file is missing entirely, that is fine — a fresh unscoped DB has no config project: block. Continue.)

1b — Existing anchor already in the DB?

query_items(operation="search", type="project", depth=0)

(list mode — query omitted, filtering by type and depth.)

• No results → continue to 1c.

• One or more results → do NOT silently create a second anchor. Offer, via AskUserQuestion:

  1. Attach to existing — write the existing anchor's UUID into config.yaml (skip anchor creation in EXECUTE; still re-parent MOVE roots under it) and continue.
  2. Abort — stop and let the user resolve the ambiguity manually.

  If the user picks "attach", record the existing anchor UUID as ANCHOR_ID and note that EXECUTE step (a) is skipped.

1c — Server capability probe (the depth-sweep fix)

Bulk re-parenting is exactly the scenario that a pre-fix server corrupts: on a pre-#219/#220 server, re-parenting a subtree does NOT recompute descendant depths (bug 99a3e642), so this skill would silently leave the moved trees with wrong depths. Verify the fix is deployed with a disposable probe, then delete it.

Build a probe where a grandchild's depth MUST change when a middle node is re-parented deeper:

1. Create a throwaway root and a two-level branch under it in one call:

   manage_items(operation="create", items=[
     { title: "zzprobe-root",  type: "container", priority: "low" }
   ])
   

   Capture its UUID as P.
2. Create the branch (sequential parentage, small tree). manage_items create has no ref/parentRef mechanism (only create_work_tree does), so a sibling's UUID does not exist until its own create call returns — M and G cannot be created in the same batch since G's parentId needs M's real UUID:

   manage_items(operation="create", items=[
     { title: "zzprobe-A",   parentId: P,  priority: "low" }     → capture as A (depth 1)
   ])
   

   manage_items(operation="create", items=[
     { title: "zzprobe-M",   parentId: P,  priority: "low" }     → capture as M (depth 1, sibling of A)
   ])
   

   Capture M's returned UUID, then create G referencing it:

   manage_items(operation="create", items=[
     { title: "zzprobe-G",   parentId: "<M's real UUID>",  priority: "low" }     → capture as G (depth 2, child of M)
   ])
   

3. Re-parent the middle node M under A (making it deeper):

   manage_items(operation="update", items=[{ itemId: M, parentId: A }])
   

   Post-fix, M becomes depth 2 and G becomes depth 3.
4. Read the grandchild's depth and capture it:

   query_items(operation="get", itemId=G)
   

5. Delete the probe immediately, before acting on the result — this runs on every path, pass or fail:

   manage_items(operation="delete", itemIds=[P], recursive=true)
   

6. Now evaluate the captured depth:
   • depth == 3 → fix is present. Continue.
   • depth == 2 (stale) → abort (probe already deleted):

     ⊘ Server is missing the reparent depth-sweep fix (bug 99a3e642).
       Bulk re-parenting on this server would corrupt subtree depths.
       Upgrade the Task Orchestrator server (PR #219/#220 or later) and retry.
     

--dry-run skips this probe entirely — no execution will happen, so the capability check is unnecessary and the dry run stays genuinely mutation-free. The probe runs only on the real-execution path, after the user confirms in Step 3.

1d — Config-push capability (tolerant)

manage_project_config may be absent on older servers. Do not probe it destructively here — just remember to attempt the push in EXECUTE step (d) and, if the tool is unavailable, skip it with a note rather than failing the whole adoption. The local config.yaml write (step c) is the source of truth; the server push is a convenience sync.

---

Step 2 — Inventory & Classify

Full depth-0 census:

query_items(operation="overview", excludeTerminal=false, includeChildren=true, limit=<total>)

If the response reports truncated: true, re-issue with limit set to the reported total so no root is missed.

Classify every depth-0 root into exactly one bucket:

Bucket	Rule	Action
KEEP-GLOBAL	Title matches a global container — Session Retrospectives, Improvement Proposals; OR the root itself is tagged/typed agent-observation (these are standalone depth-0 items, each its own root — never children of a container).	Stays at depth 0.
MOVE	Any work container or work tree (a root with work/queue/review children), and any standalone work item. Everything that is real project work.	Re-parented under the new anchor.
CLEANUP-CANDIDATE	Evident test artifacts: titles containing probe, smoke, depth-test, zzprobe; or tags matching mtest-*.	Flagged only — never moved, never deleted. Recommend /batch-complete.

Ambiguous roots (no clear rule match — e.g., an untagged standalone item that could be work or a stray container): do NOT guess. Collect them and present via AskUserQuestion (multiSelect) asking which should MOVE vs stay KEEP-GLOBAL. Test-artifact-looking items always go to CLEANUP-CANDIDATE without asking.

---

Step 3 — Dry-Run Plan (always shown; --dry-run stops here)

Render the full plan before any mutation. Require explicit confirmation to proceed.

◆ Adopt Project Scope — Plan   [project: "<name>"]

| Root | ID | Classification | Action |
|------|----|----------------|--------|
| Auth System | `a1b2c3d4` | MOVE | re-parent under new anchor |
| Payments | `e5f6a7b8` | MOVE | re-parent under new anchor |
| Session Retrospectives | `c9d0e1f2` | KEEP-GLOBAL | stays at depth 0 |
| Improvement Proposals | `13243546` | KEEP-GLOBAL | stays at depth 0 |
| zzprobe-smoke-tree | `5768798a` | CLEANUP-CANDIDATE | flag for /batch-complete (not moved) |

Summary: 2 move · 2 stay global · 1 cleanup candidate
Execution will create a "<name>" project anchor and re-parent 2 tree(s) under it.

• If the project name is still unknown, ask for it now via AskUserQuestion before showing the final counts.
• --dry-run: stop here. State plainly: "Dry run — no changes made. Re-run without --dry-run to execute."
• Otherwise, confirm via AskUserQuestion:

  ◆ Proceed with adoption? This re-parents <N> tree(s) under a new project anchor.
    1. Yes — execute
    2. No — abort, make no changes
  

  Wait for the answer. Only "Yes" proceeds.

---

Step 4 — Execute

Perform in this order. Record pre-execution counts first (used by Step 5): the depth-0 root count, the MOVE count, and the KEEP-GLOBAL count from Step 2.

(a) Create the project anchor — skip if attaching to an existing anchor (Step 1b):

manage_items(operation="create", items=[{
  title: "<project name>",
  type: "project",
  summary: "Project anchor — subtree scope for <project name>",
  priority: "low"
}])

Capture the new UUID as ANCHOR_ID.

(b) Batch re-parent the MOVE roots — one call, items array (never a sequential call per root):

manage_items(operation="update", items=[
  { itemId: "<move-root-1>", parentId: ANCHOR_ID },
  { itemId: "<move-root-2>", parentId: ANCHOR_ID },
  ...
])

This relies on the depth-sweep fix verified in Step 1c — each moved subtree's descendant depths and root_id are recomputed server-side.

(c) Write the project: block into config.yaml — read-modify-write, preserving ALL existing content:

• Read the current .taskorchestrator/config.yaml text (create the file with just the block if it does not exist).
• Insert this top-level block (surgical insert/append — do NOT regenerate or reformat the rest of the file; leave work_item_schemas:, traits:, actor_authentication:, comments, and formatting byte-for-byte intact):

  project:
    rootId: "<ANCHOR_ID>"
    name: "<project name>"
  

• If a project: key somehow already exists (it should not — Step 1a would have aborted), update its rootId/name in place rather than adding a duplicate key.

(d) Push the config server-side (tolerant — skip if the tool is absent):

manage_project_config(operation="push", rootId=ANCHOR_ID, configYaml="<full config.yaml text>")

• A warning field about the root's type is only returned when the anchor's type is not project; since step (a) sets type: "project", none is expected. Report it if present but treat it as non-fatal.
• If manage_project_config is unavailable on this server, skip this step and note: "Config pushed locally only — server does not support manage_project_config; the local config.yaml is authoritative."

---

Step 5 — Verify & Reconcile

Confirm the migration landed correctly. On ANY mismatch, report loudly and do NOT auto-rollback (say the remedy explicitly).

1. Anchored child count — the new anchor's direct children must equal the MOVE count:

   query_items(operation="overview", anchorId=ANCHOR_ID)
   

   The anchor's direct-child count must equal N move.
2. Global census — remaining depth-0 roots must reconcile:

   query_items(operation="overview", excludeTerminal=false, limit=<total>)
   

   Expected depth-0 roots = KEEP-GLOBAL count + 1 (the anchor) + any CLEANUP-CANDIDATE roots left in place (cleanup candidates were flagged, not moved). Confirm the moved roots are no longer at depth 0.
3. Depth spot-check — pick one moved tree that had a grandchild; confirm the grandchild's depth increased by exactly 1 from its pre-move value (the anchor added one level above the old root):

   query_items(operation="get", itemId="<grandchild-of-a-moved-tree>")
   

Render a before/after table:

✓ Adoption Complete — "<project name>"  (anchor `<8-char-id>`)

|                     | Before | After |
|---------------------|--------|-------|
| Depth-0 roots       | 5      | 4     |
| Under project anchor| 0      | 2     |
| Global containers   | 2      | 2     |
| Cleanup candidates  | 1      | 1 (flagged, not moved) |

↳ Config: project.rootId written to .taskorchestrator/config.yaml
↳ Server push: applied | skipped (tool absent)
↳ Cleanup candidates flagged for /batch-complete: <titles>

On mismatch (e.g., anchored child count ≠ MOVE count):

⚠ Reconciliation mismatch — expected <X> children under the anchor, found <Y>.
  No rollback was performed. To undo: re-parent the affected roots back to depth 0
  with manage_items(operation="update", items=[{ itemId, parentId: null }]) for each,
  then delete the anchor. Investigate before retrying.

Remind the user that schema changes / new config require an MCP reconnect (/mcp) to take effect if they rely on per-root schema resolution immediately.

---

Safety Summary

• Default dry run. No mutation without an explicit AskUserQuestion "Yes".
• Never deletes user data. Cleanup candidates are only flagged; the sole deletion is the throwaway server probe in Step 1c.
• Never regenerates config.yaml. The project: block is surgically inserted; all other content is preserved verbatim.
• Abort, don't corrupt. A pre-fix server (missing the depth-sweep) aborts in preflight rather than silently corrupting subtree depths.
• No auto-rollback. On verify mismatch, the skill reports the manual remedy rather than guessing at an undo.

---

Verification (before first real run)

Per the specification, exercise the skill against a COPY of a production-shaped DB:

1. Dry run on the copy must produce zero mutations and a correct classification table.
2. Execute on the copy and confirm Step 5 count reconciliation passes (depth-0 roots, anchored children, grandchild depth +1).

Only after the copy passes should the skill be run against the real database.
