Update Semantic Sub-Skill

Appends new content to semantic notes based on daily review synthesis. Handles multiple note types and preserves existing content.

Input Arguments

Arguments are passed as key-value pairs:

•vault: Path to the vault
•updates: JSON array of updates to apply

Update format:

json

{
  "updates": [
    {
      "type": "person",
      "path": "02_Areas/People/SarahK.md",
      "section": "Interactions",
      "content": "2026-02-14: Discussed career growth goals. She's interested in tech lead path."
    },
    {
      "type": "project",
      "path": "01_Projects/2026-03-15-platform-migration.md",
      "section": "Progress",
      "content": "2026-02-14: API design finalized. Ready for implementation."
    },
    {
      "type": "insight",
      "path": "02_Areas/Insights/delegation.md",
      "section": "Evidence",
      "content": "2026-02-14: Letting Sarah lead the design review freed up 2 hours."
    },
    {
      "type": "resource",
      "path": "03_Resources/articles/distributed-systems.md",
      "section": "Notes",
      "content": "Captured from daily review. Key insight: CAP theorem tradeoffs."
    }
  ]
}

Instructions

1. Parse Updates

Parse the updates JSON array. Validate each update has:

•type - One of: person, project, insight, area, resource
•path - Relative path from vault root
•section - Target section heading in the note
•content - Content to append

2. Process Each Update

For each update:

2.1 Resolve Full Path

code

$VAULT/{update.path}

2.2 Check File Exists

If file doesn't exist:

•Log warning: "Note not found: {path}"
•Add to skipped array with reason
•Continue to next update

2.3 Read Existing Content

Read the full content of the semantic note.

2.4 Find Target Section

Locate the section heading matching ## {section}:

•If exact match found → append after section content
•If section not found → append new section at end

2.5 Append Content

Insert the new content:

•Add a blank line before the new content
•Prepend content with bullet point if not already formatted
•Preserve any existing content in the section

Example transformation:

Before:

markdown

## Interactions

- 2026-02-10: Onboarding check-in

After:

markdown

## Interactions

- 2026-02-10: Onboarding check-in
- 2026-02-14: Discussed career growth goals. She's interested in tech lead path.

2.6 Write Updated File

Write the modified content back to the file.

3. Handle New Notes (Optional)

If type is resource and file doesn't exist, create a minimal note:

markdown

---
created: {date}
source: daily-review
---

# {title extracted from path}

## Notes

- {content}

For other types, skip creation (user should create the note structure).

4. Return Result

Success:

json

{
  "success": true,
  "applied": [
    { "path": "02_Areas/People/SarahK.md", "section": "Interactions", "status": "appended" },
    { "path": "01_Projects/2026-03-15-platform-migration.md", "section": "Progress", "status": "appended" }
  ],
  "skipped": [
    { "path": "02_Areas/Insights/new-concept.md", "reason": "file_not_found" }
  ],
  "created": [
    { "path": "03_Resources/articles/distributed-systems.md", "status": "created" }
  ]
}

Partial success:

json

{
  "success": true,
  "partial": true,
  "applied": [...],
  "skipped": [...],
  "message": "Some updates skipped. See details above."
}

Failure:

json

{
  "success": false,
  "error": "invalid_updates",
  "message": "Failed to parse updates JSON"
}

Semantic Note Paths by Type

Type	Expected Path Pattern	Default Section
person	`02_Areas/People/{Name}.md`	Interactions
project	`01_Projects/{date-name}.md`	Progress
insight	`02_Areas/Insights/{topic}.md`	Evidence
area	`02_Areas/{name}.md`	Notes
resource	`03_Resources/{category}/{name}.md`	Notes

Safety

•Always read before write to preserve existing content
•Never delete or overwrite existing section content
•Only append to existing sections
•Skip updates for non-existent files (except resources)
•Log all actions for transparency
