+# Call Wrapper Artifacts Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Let `wf.workflow.call_capability` execute saved `WorkflowArtifact(kind="wrapper")` artifacts by their stable artifact node name without turning arbitrary saved workflows into node capabilities.
+
+**Architecture:** Keep live `NodeSpec` execution unchanged. Extend the workflow surface resolution path so `workflow.<artifact_id>.v<version>` can resolve to a saved wrapper artifact, validate that it is wrapper-kind and interrupt-free, execute its stored plan through the existing workflow runner, and normalize the final workflow result into the same `qualified_name` / `outcome` / `output` payload shape as live capabilities.
+
+**Tech Stack:** Python, Pydantic, `wf_artifacts`, `wf_core`, pytest.
+
+---
+
+### Task 1: Pin Wrapper-Artifact Call Semantics
+
+**Files:**
+- Modify: `tests/wf_mcp/test_service.py`
+
+- [ ] **Step 1: Write the failing test**
+
+Add a test that saves a wrapper artifact with a simple one-node plan, calls `WorkflowSurfaceHandlers.call_capability()` with `workflow.<id>.v<version>`, and asserts the returned `qualified_name`, `outcome`, and `output`.
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `uv run --with pytest pytest tests/wf_mcp/test_service.py -q`
+
+Expected: FAIL because `call_capability()` only resolves live specs today.
+
+### Task 2: Resolve Wrapper Artifacts in the Workflow Surface
+
+**Files:**
+- Modify: `src/wf_mcp/workflow_surface/handlers.py`
+
+- [ ] **Step 1: Implement minimal wrapper-artifact resolution**
+
+Add a small helper that:
+- recognizes stable artifact node names
+- loads the artifact from the store
+- rejects non-wrapper artifacts
+- rejects unsupported interrupt plans
+- executes the artifact plan with the existing workflow runner
+- converts the workflow run into the `call_capability` response payload
+
+- [ ] **Step 2: Run focused tests**
+
+Run: `uv run --with pytest pytest tests/wf_mcp/test_service.py -q`
+
+Expected: PASS.
+
+### Task 3: Verify the Whole Project
+
+**Files:**
+- No additional files.
+
+- [ ] **Step 1: Run focused workflow-surface tests**
+
+Run: `uv run --with pytest pytest tests/wf_mcp -q`
+
+Expected: PASS.
+
+- [ ] **Step 2: Run the full suite**
+
+Run: `uv run --with pytest pytest -q`
+
+Expected: PASS.
