Schema Application

Apply inferred conventions to incomplete notes. Suggests and adds missing fields based on what similar notes have.

When to Use

Invoke when you want to:

Add missing frontmatter fields to notes
Batch-fix incomplete metadata
Apply folder conventions to outliers
Normalize notes to match their peers

Arguments

Argument	Required	Description
folder	No	Folder to apply schema to. Omit for entire vault.
path	No	Specific note to fix. Takes precedence over folder.

Process

1. Parse User Input

Recognize application requests:

"apply inferred schema to incomplete notes"
"add missing fields to meetings/"
"fix incomplete notes in projects/"

2. Find Incomplete Notes

mcp__flywheel__find_incomplete_notes({
  folder: "meetings/",
  min_frequency: 0.7
})

3. Preview Changes

## Schema Application Preview

I'll add missing fields based on inferred conventions:

### meetings/2025-12-20 Client Call.md
Adding:
```yaml
attendees:
  - [[Sarah Chen]]
  - [[Marcus Johnson]]
tags:
  - meeting
  - client

meetings/2025-12-22 Quick Sync.md

Adding:

tags:
  - meeting
  - standup

Proceed with these changes? (y/n)


### 4. Apply Changes (with confirmation)

Use Read to get current content, Edit to add fields.

### 5. Verify Changes (Gate 6)

After each Edit:
1. **Re-read the modified file** to verify changes
2. **Check if the new fields are present** in frontmatter
3. **Handle failures**:
   - If Edit is blocked or failed: Inform user and skip to next file
   - If fields not found after edit: Alert user "Edit may have failed"
   - If succeeded: Only report success if verification confirms the fields were added

### 6. Report Results

Schema Application Complete

Applied to 3 notes: ✓ meetings/2025-12-20 Client Call.md - 2 fields added ✓ meetings/2025-12-22 Quick Sync.md - 1 field added ✗ meetings/2025-12-23 Standup.md - Edit blocked (permission denied)

If any edits failed, you can apply them manually.


## Six Gates Compliance

| Gate | Implementation |
|------|----------------|
| 1. Read Before Write | Reads current file before any changes |
| 2. File Exists | Validates file exists via find_incomplete_notes |
| 3. Chain Validation | N/A (single step) |
| 4. Mutation Confirmation | Always shows preview, requires confirmation |
| 5. Health Check | Uses MCP health infrastructure |
| 6. Post Validation | Re-reads file after Edit, verifies fields present |

## Use Cases

- **Batch normalization**: "Make all meeting notes consistent"
- **New note completion**: "Add standard fields to my new note"
- **Migration support**: "Ensure all notes have required fields"

## Integration

Works well with other skills:
- **schema-infer**: See what fields will be applied
- **schema-gaps**: Find notes needing fixes
- **promote-frontmatter**: Extract prose patterns first
