# Wrapper Draft Next Actions 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:** Add advisory `next_actions` to `wf.workflow.create_draft_workspace_from_capability` so LLM clients can continue safely even when they cannot easily read the docs.
**Architecture:** Keep `wrapper_hints` as the source of truth for scaffold confidence, missing decisions, and mapping warnings. Add a small typed result object that converts those hints into concrete next-tool guidance. `can_save_now` is advisory only; do not block saving or enforce policy in this slice.
**Tech Stack:** Python 3.14, Pydantic v2, FastMCP tool schemas, pytest, ruff, basedpyright.
---
## Scope
Add `next_actions` to `CreateDraftWorkspaceFromCapabilityResult` and handler payloads.
Do:
- Return machine-readable guidance from `create_draft_workspace_from_capability`.
- Make `can_save_now` advisory only.
- Recommend `wf.workflow.patch_draft_workspace` when `wrapper_hints.missing_decisions` is non-empty or confidence is low.
- Recommend `wf.workflow.validate_draft_workspace` when the scaffold looks safe enough to validate.
- Include patch examples for common missing decisions.
- Document the field and add schema tests.
Do not:
- Block `create_artifact_from_workspace`.
- Add a new tool.
- Infer raw MCP `content[0].text` automatically.
- Treat boolean output candidates as real routing semantics.
- Replace `wrapper_hints`; `next_actions` should summarize and guide, not duplicate every hint.
## Files
- Modify: `src/wf_mcp/workflow_surface/models.py`
- Add typed `WrapperDraftNextActions` and `WrapperDraftPatchExample` Pydantic models.
- Add `next_actions` field to `CreateDraftWorkspaceFromCapabilityResult`.
- Modify: `src/wf_mcp/workflow_surface/handlers.py`
- Add helper that derives `next_actions` from `wrapper_hints` and workspace id/revision.
- Include `next_actions` in `create_draft_workspace_from_capability` result.
- Test: `tests/wf_mcp/workflow_surface/test_drafts.py`
- Assert high-confidence draft returns validate/save guidance.
- Assert low-confidence content-block draft returns patch guidance and advisory `can_save_now=false`.
- Test: `tests/wf_mcp/server/test_config.py`
- Assert output schema exposes `next_actions` with field descriptions.
- Modify: `docs/workflow_capabilities.md`
- Explain `next_actions` as advisory continuation hints.
- Modify: `docs/wf_mcp_end_to_end_runbook.md`
- Mention that clients can follow `next_actions` after draft creation.
## Data Shape
Add this output shape:
```json
{
"next_actions": {
"can_save_now": true,
"recommended_next_tool": "wf.workflow.validate_draft_workspace",
"reason": "Wrapper hints are high confidence and have no missing decisions.",
"patch_examples": [],
"warnings": []
}
}
```
Low-confidence example:
```json
{
"next_actions": {
"can_save_now": false,
"recommended_next_tool": "wf.workflow.patch_draft_workspace",
"reason": "Review missing wrapper decisions before saving.",
"patch_examples": [
{
"description": "Replace the output bindings after choosing workflow state fields.",
"tool": "wf.workflow.patch_draft_workspace",
"request": {
"workspace_id": "echo_wrapper",
"revision": 1,
"patch": [
{
"op": "replace",
"path": "/draft/steps/call/output",
"value": []
}
]
}
}
],
"warnings": [
"Raw MCP content blocks are not workflow-shaped. Use an explicit wrapper or extraction node."
]
}
}
```
## Task 1: Add Result Models And Schema Test
**Files:**
- Modify: `src/wf_mcp/workflow_surface/models.py`
- Modify: `tests/wf_mcp/server/test_config.py`
- [ ] **Step 1: Add failing schema assertions**
In `tests/wf_mcp/server/test_config.py`, inside the test that already inspects `create_draft_workspace_from_capability` output schema, add:
```python
assert "next_actions" in from_capability_output["properties"]
next_actions_schema = from_capability_output["properties"]["next_actions"]
assert "recommended_next_tool" in next_actions_schema["properties"]
assert "patch_examples" in next_actions_schema["properties"]
assert "advisory" in next_actions_schema["properties"]["can_save_now"]["description"]
```
Run:
```powershell
uv run pytest tests/wf_mcp/server/test_config.py -q
```
Expected: fail because `next_actions` is not in the output schema.
- [ ] **Step 2: Add Pydantic result models**
In `src/wf_mcp/workflow_surface/models.py`, add near `CreateDraftWorkspaceFromCapabilityResult`:
```python
class WrapperDraftPatchExample(BaseModel):
"""Concrete patch-workspace example for a likely next authoring edit."""
description: str = Field(description="Human-readable reason for this patch.")
tool: str = Field(description="MCP tool to call for this example.")
request: dict[str, Any] = Field(
description="JSON request payload to pass to the tool."
)
class WrapperDraftNextActions(BaseModel):
"""Advisory continuation hints after bootstrapping a wrapper draft."""
can_save_now: bool = Field(
description=(
"Advisory only. False means the scaffold likely needs review before "
"saving, but the server does not enforce this."
)
)
recommended_next_tool: str = Field(
description=(
"Suggested next MCP tool, usually wf.workflow.validate_draft_workspace "
"or wf.workflow.patch_draft_workspace."
)
)
reason: str = Field(description="Short explanation for the recommendation.")
patch_examples: list[WrapperDraftPatchExample] = Field(
default_factory=list,
description="Concrete JSON Patch examples for common missing decisions.",
)
warnings: list[str] = Field(
default_factory=list,
description="Non-blocking warnings copied from low-confidence wrapper hints.",
)
```
Then update:
```python
class CreateDraftWorkspaceFromCapabilityResult(DraftWorkspaceResult):
"""Draft workspace result plus wrapper hints and advisory next actions."""
wrapper_hints: dict[str, Any] = Field(...)
next_actions: WrapperDraftNextActions = Field(
description=(
"Advisory next step guidance derived from wrapper_hints. "
"The server does not enforce can_save_now."
)
)
```
- [ ] **Step 3: Run schema test**
Run:
```powershell
uv run pytest tests/wf_mcp/server/test_config.py -q
```
Expected: schema assertion passes, but runtime tests may still fail later until handler returns `next_actions`.
## Task 2: Derive Next Actions In The Handler
**Files:**
- Modify: `src/wf_mcp/workflow_surface/handlers.py`
- Modify: `tests/wf_mcp/workflow_surface/test_drafts.py`
- [ ] **Step 1: Add high-confidence behavior test**
In `tests/wf_mcp/workflow_surface/test_drafts.py`, extend `test_workflow_surface_creates_draft_workspace_from_capability_hints`:
```python
next_actions = result["next_actions"]
assert next_actions["can_save_now"] is True
assert next_actions["recommended_next_tool"] == "wf.workflow.validate_draft_workspace"
assert "high confidence" in next_actions["reason"]
assert next_actions["patch_examples"] == []
assert next_actions["warnings"] == []
```
Run:
```powershell
uv run pytest tests/wf_mcp/workflow_surface/test_drafts.py::test_workflow_surface_creates_draft_workspace_from_capability_hints -q
```
Expected: fail because handler does not return `next_actions`.
- [ ] **Step 2: Add low-confidence behavior test**
Find or create a content-block capability test near existing wrapper hint tests. Use an output schema shaped like:
```python
content_output_schema = {
"type": "object",
"properties": {
"content": {
"type": "array",
"items": {
"type": "object",
"properties": {
"type": {"type": "string"},
"text": {"type": "string"},
},
},
}
},
}
```
Register a NodeSpec/capability with that output schema, call `create_draft_workspace_from_capability`, then assert:
```python
next_actions = result["next_actions"]
assert next_actions["can_save_now"] is False
assert next_actions["recommended_next_tool"] == "wf.workflow.patch_draft_workspace"
assert "missing wrapper decisions" in next_actions["reason"]
assert next_actions["patch_examples"][0]["tool"] == "wf.workflow.patch_draft_workspace"
assert next_actions["patch_examples"][0]["request"]["workspace_id"] == "content_wrapper"
assert next_actions["patch_examples"][0]["request"]["revision"] == result["revision"]
assert next_actions["warnings"]
```
Run:
```powershell
uv run pytest tests/wf_mcp/workflow_surface/test_drafts.py -q
```
Expected: fail until implementation exists.
- [ ] **Step 3: Implement helper in handler**
In `src/wf_mcp/workflow_surface/handlers.py`, add a helper near other draft helpers:
```python
def _wrapper_draft_next_actions(
*,
workspace_id: str,
revision: int,
hints: dict[str, Any],
) -> dict[str, Any]:
"""Convert wrapper_hints into advisory next-tool guidance for MCP clients."""
confidence = str(hints.get("confidence", "low"))
missing_decisions = hints.get("missing_decisions")
notes = [str(note) for note in hints.get("notes", []) if isinstance(note, str)]
has_missing = isinstance(missing_decisions, list) and len(missing_decisions) > 0
can_save_now = confidence == "high" and not has_missing
if can_save_now:
return {
"can_save_now": True,
"recommended_next_tool": "wf.workflow.validate_draft_workspace",
"reason": "Wrapper hints are high confidence and have no missing decisions.",
"patch_examples": [],
"warnings": [],
}
return {
"can_save_now": False,
"recommended_next_tool": "wf.workflow.patch_draft_workspace",
"reason": "Review missing wrapper decisions before saving.",
"patch_examples": _wrapper_draft_patch_examples(
workspace_id=workspace_id,
revision=revision,
hints=hints,
),
"warnings": notes,
}
```
Add:
```python
def _wrapper_draft_patch_examples(
*,
workspace_id: str,
revision: int,
hints: dict[str, Any],
) -> list[dict[str, Any]]:
"""Return conservative JSON Patch examples without guessing semantics."""
examples: list[dict[str, Any]] = []
missing_decisions = hints.get("missing_decisions")
if not isinstance(missing_decisions, list):
return examples
decision_kinds = {
str(decision.get("kind"))
for decision in missing_decisions
if isinstance(decision, dict)
}
if {
"choose_output_fields",
"review_nested_output",
} & decision_kinds:
examples.append(
{
"description": (
"Replace output bindings after choosing which capability "
"outputs should be written to workflow state."
),
"tool": "wf.workflow.patch_draft_workspace",
"request": {
"workspace_id": workspace_id,
"revision": revision,
"patch": [
{
"op": "replace",
"path": "/draft/steps/call/output",
"value": [],
}
],
},
}
)
if "confirm_boolean_outcomes" in decision_kinds:
examples.append(
{
"description": (
"Review boolean output candidates before adding routing; "
"do not route on boolean fields automatically."
),
"tool": "wf.workflow.patch_draft_workspace",
"request": {
"workspace_id": workspace_id,
"revision": revision,
"patch": [],
},
}
)
return examples
```
Then change the return in `create_draft_workspace_from_capability`:
```python
return {
**result,
"wrapper_hints": hints,
"next_actions": _wrapper_draft_next_actions(
workspace_id=workspace_id,
revision=int(result["revision"]),
hints=hints,
),
}
```
- [ ] **Step 4: Run behavior tests**
Run:
```powershell
uv run pytest tests/wf_mcp/workflow_surface/test_drafts.py tests/wf_mcp/server/test_config.py -q
```
Expected: pass.
## Task 3: Document Next Actions
**Files:**
- Modify: `docs/workflow_capabilities.md`
- Modify: `docs/wf_mcp_end_to_end_runbook.md`
- [ ] **Step 1: Update workflow capability docs**
In `docs/workflow_capabilities.md`, near the `wrapper_hints` section, add:
```markdown
`create_draft_workspace_from_capability` also returns `next_actions`.
This is advisory guidance for clients that cannot easily read the full docs.
It summarizes whether the scaffold is safe-looking enough to validate, which
tool to call next, and concrete patch examples for common missing decisions.
`next_actions.can_save_now` is not enforced. A caller can still save a low
confidence draft, but the field exists to make that risk explicit.
```
- [ ] **Step 2: Update runbook**
In `docs/wf_mcp_end_to_end_runbook.md`, near the draft-from-capability example, add:
```markdown
After `create_draft_workspace_from_capability`, inspect `next_actions`.
If `recommended_next_tool` is `wf.workflow.patch_draft_workspace`, apply or
adapt the returned `patch_examples` before saving. If it recommends
`wf.workflow.validate_draft_workspace`, validate the draft before creating an
artifact.
```
- [ ] **Step 3: Grep docs**
Run:
```powershell
rg -n "next_actions|can_save_now|patch_examples" docs/workflow_capabilities.md docs/wf_mcp_end_to_end_runbook.md
```
Expected: all three terms appear.
## Task 4: Final Verification
**Files:**
- All touched files.
- [ ] **Step 1: Run focused tests**
Run:
```powershell
uv run pytest tests/wf_mcp/workflow_surface/test_drafts.py tests/wf_mcp/server/test_config.py tests/wf_mcp/test_workflow_wrapper_hints.py -q
```
Expected: pass.
- [ ] **Step 2: Run touched-file lint and format check**
Run:
```powershell
uv run ruff check src/wf_mcp/workflow_surface/models.py src/wf_mcp/workflow_surface/handlers.py tests/wf_mcp/workflow_surface/test_drafts.py tests/wf_mcp/server/test_config.py
uv run ruff format --check src/wf_mcp/workflow_surface/models.py src/wf_mcp/workflow_surface/handlers.py tests/wf_mcp/workflow_surface/test_drafts.py tests/wf_mcp/server/test_config.py
```
Expected: pass.
- [ ] **Step 3: Run touched-file type check**
Run:
```powershell
uv run basedpyright --level error src/wf_mcp/workflow_surface/models.py src/wf_mcp/workflow_surface/handlers.py tests/wf_mcp/workflow_surface/test_drafts.py tests/wf_mcp/server/test_config.py
```
Expected: `0 errors`.
- [ ] **Step 4: Optional full suite**
Run when time allows:
```powershell
uv run pytest -q
```
Expected current baseline: full suite passes with the existing skip/xfail count.
## Notes For Opencode
- `can_save_now` is advisory. Do not enforce it.
- Do not add a new save gate.
- Do not generate semantic routes from boolean fields.
- Keep patch examples conservative; empty patch examples are acceptable when the missing decision cannot be safely represented.
- Avoid whole-dict assertions. Assert individual fields.
- Existing docs may be long; keep additions short.
