Artifact Metadata

artifact-metadata

Manage artifact metadata, versioning, ownership, and history tracking.

Triggers

• "update artifact metadata"
• "track artifact version"
• "artifact history"
• "who owns [artifact]"
• "artifact status"
• "version [artifact]"

Purpose

This skill provides consistent metadata management for all SDLC and marketing artifacts. It tracks ownership, versioning, review history, and status across the artifact lifecycle.

Behavior

When triggered, this skill:

1. Locates or creates metadata:

   • Check for existing metadata.json alongside artifact
   • Create new metadata if none exists
   • Validate against metadata schema

2. Updates metadata fields:

   • Version (semantic versioning)
   • Status (draft, review, baselined, deprecated)
   • Owner (agent or user)
   • Reviewers (list of reviewing agents)
   • Timestamps (created, modified, baselined)

3. Tracks history:

   • Version history with change summaries
   • Review records with reviewer and outcome
   • Approval records

4. Validates relationships:

   • Parent/child artifact links
   • Requirement traceability links
   • Cross-references to related artifacts

Usage Examples

Create New Metadata

User: "Create metadata for the SAD"

Skill creates:
.aiwg/architecture/sad/metadata.json
{
  "artifact_id": "SAD-001",
  "name": "Software Architecture Document",
  "type": "architecture",
  "version": "0.1.0",
  "status": "draft",
  "owner": "architecture-designer",
  "created": "2025-12-08T14:30:00Z",
  "modified": "2025-12-08T14:30:00Z",
  "reviewers": [],
  "history": [],
  "reviews": []
}

Update Version After Changes

User: "Version the SAD to 1.0.0 with summary 'Initial baseline'"

Skill updates:
- version: "1.0.0"
- status: "baselined"
- baselined: "2025-12-08T16:45:00Z"
- history: [adds entry with version, date, summary]

Record Review

User: "Record security-architect review as approved"

Skill updates:
- reviews: [adds review record]
- reviewers: [adds "security-architect" if not present]
- modified: [updates timestamp]

Query Ownership

User: "Who owns the test plan?"

Skill responds:
"Test Plan (TP-001) is owned by test-architect.
Status: review
Version: 0.3.0
Last modified: 2025-12-07
Reviewers: security-auditor, requirements-analyst"

Status Lifecycle

draft → review → approved → baselined
  ↑        ↓
  └── rejected (returns to draft)

baselined → deprecated (end of life)

Status Transitions

Version Conventions

• 0.x.x: Draft versions (not baselined)
• 1.0.0: First baseline
• x.y.0: Minor changes (compatible)
• x.0.0: Major changes (may break traceability)

Auto-Version Rules

Artifact Type Conventions

CLI Usage
