Design Document Update

Updates design documentation files with new content, metadata changes, or structural improvements.

Overview

This skill updates design documents by:

1. Reading the current design doc
2. Understanding the requested changes
3. Validating changes against schema
4. Updating frontmatter metadata
5. Modifying content sections
6. Running validation checks
7. Confirming changes applied correctly

Quick Start

Update status:

/design-update effect-type-registry cache-optimization.md --status=draft

Update completeness:

/design-update effect-type-registry observability.md --completeness=80

Mark as synced:

/design-update effect-type-registry cache-optimization.md --sync

Update section:

/design-update rspress-plugin-api-extractor type-loading.md --section=Overview

Bulk update:

/design-update effect-type-registry observability.md \
  --status=current --completeness=90 --sync

Parameters

Required

• module - Module name
• doc - Document filename (without path)

Optional

• status - New status (stub, draft, current, needs-review, archived)
• completeness - New completeness (0-100)
• section - Specific section to update
• content - New content to add/replace
• sync - Mark as synced (sets last-synced to current date)
• add-related - Add cross-reference to related doc
• add-dependency - Add dependency reference

Workflow Overview

1. Parse Parameters - Extract module, doc, and change parameters
2. Load Configuration - Read config, verify module exists
3. Read Document - Parse current frontmatter and content
4. Apply Updates - Frontmatter or content changes
5. Validate Changes - Check alignment and correctness
6. Smart Recommendations - Suggest related updates
7. Report Changes - Summary with validation results
