Validate Metadata

You validate all AIWG extension definitions (agents, skills, commands, behaviors) against the metadata schema. You report errors with field names, line numbers, and remediation hints — and return a clean pass/fail summary.

Triggers

Alternate expressions and non-obvious activations (primary phrases are matched automatically from the skill description):

  • "are my extensions valid?" → run full metadata validation
  • "check my agent definitions" → validate agent metadata specifically
  • "is this skill definition correct?" → validate single extension file
  • "prep for release" → validate metadata as part of pre-release checks

Trigger Patterns Reference

Pattern Example Action
Validate request "validate metadata" Run aiwg validate-metadata
Check request "check metadata" Run aiwg validate-metadata
Validate extensions "validate extensions" Run aiwg validate-metadata
Quality check "metadata quality" Run aiwg validate-metadata
Single file "validate this agent file" Run aiwg validate-metadata <path>
Type-scoped "validate just the skills" Run aiwg validate-metadata --type skills
Fix mode "validate and report errors clearly" Run aiwg validate-metadata --verbose

Behavior

When triggered:

  1. Extract intent:

    • Is validation scoped to a specific extension type (agents, skills, commands, behaviors)?
    • Is a specific file path mentioned?
    • Is verbose output needed?
  2. Run the appropriate command:

    bash
    # Default: validate all extensions
    aiwg validate-metadata
    
    # Verbose output with line numbers and hints
    aiwg validate-metadata --verbose
    
    # Scope to a specific type
    aiwg validate-metadata --type agents
    aiwg validate-metadata --type skills
    aiwg validate-metadata --type commands
    aiwg validate-metadata --type behaviors
    
    # Validate a single file
    aiwg validate-metadata agentic/code/addons/aiwg-utils/skills/my-skill/SKILL.md
    
    # Machine-readable JSON output (for CI)
    aiwg validate-metadata --json
    
  3. Report the result — list all errors with field, location, and fix hint; summarize pass/fail count.

What Gets Validated

Check Description
Required fields id, name, description, platforms present
ID format Lowercase, hyphen-separated, no spaces
Version format CalVer (YYYY.M.PATCH) for versioned extensions
Trigger phrases At least one trigger phrase defined per skill
Tool declarations Tools listed in allowedTools are valid AIWG tools
Platform list All platforms are valid (claude-code, hermes, openclaw, etc.)
Handler path handler field points to an existing file (for commands)
Duplicate IDs No two extensions share the same ID

Error Format

Errors are reported in this format:

ERROR  skills/my-skill/SKILL.md:12  missing required field: `id`
       Fix: Add `id: my-skill` to the YAML frontmatter

WARN   agents/my-agent/AGENT.md:3   version format invalid: `1.0.0`
       Fix: Use CalVer format: `2026.4.0`

PASS   commands/my-command/COMMAND.md

Examples

Example 1: Full validation before release

User: "Run metadata validation before I tag the release"

Extraction: Full validation, no scope restriction

Action:

bash
aiwg validate-metadata --verbose

Response: "Validated 47 extension definitions. 45 passed. 2 errors found:

  • skills/soul-blend/SKILL.md line 4: platforms list is empty — add at least one platform
  • agents/test-engineer/AGENT.md line 9: duplicate ID 'test-engineer' conflicts with agents/testing/test-engineer/AGENT.md"

Example 2: Scoped validation for skills only

User: "Check only the skills metadata"

Extraction: Type-scoped to skills

Action:

bash
aiwg validate-metadata --type skills

Response: "Validated 38 skill definitions. All passed."

Example 3: Single file validation

User: "Is this agent definition valid?" (with path provided)

Extraction: Single file path

Action:

bash
aiwg validate-metadata agentic/code/addons/aiwg-utils/skills/new-skill/SKILL.md

Response: "1 error: missing required field id in frontmatter (line 3). Add id: new-skill to fix."

Example 4: CI pipeline usage

Action:

bash
aiwg validate-metadata --json

Output:

json
{
  "total": 47,
  "passed": 45,
  "failed": 2,
  "errors": [
    { "file": "skills/soul-blend/SKILL.md", "line": 4, "field": "platforms", "message": "platforms list is empty" }
  ]
}
