Schema Check Phase

This is the mandatory final phase for all non-dispatcher workflows. Every workflow (except /assist:wizard) ends with schema-check validation.

Purpose

Validate all generated/modified plugin components against Claude Code plugin schemas and conventions.

Validation Rules

plugin.json Schema

Required fields:

• name: String, lowercase with hyphens, no spaces
• version: Semantic version (e.g., "1.0.0")
• description: Non-empty string
• author: Object with name field (NOT a string)

{
  "name": "my-plugin",
  "version": "1.0.0",
  "description": "Plugin description",
  "author": {
    "name": "Author Name"
  }
}

marketplace.json Schema

Required structure:

{
  "plugins": [
    {
      "location": "plugins/<name>/.claude-plugin",
      "owner": "owner-name",
      "source": {
        "type": "git",
        "url": "https://github.com/owner/repo"
      }
    }
  ]
}

File Location Rules

Component	Location Pattern
Skills	skills/<skill-name>/SKILL.md
Agents	agents/<agent-name>.md
Commands	commands/<command-name>.md
Hooks	hooks/hooks.json + hooks/*.py

YAML Frontmatter Rules

Skills:

---
name: skill-name
description: What this skill does
triggers:
  - trigger phrase 1
  - trigger phrase 2
---

Agents:

---
name: agent-name
description: Agent description
tools:
  - Tool1
  - Tool2
---

Commands:

---
name: command-name
description: Command description
allowed-tools:
  - Tool1
  - Tool2
---

Cross-Reference Validation

1. Skill → Agent pairs: Skills that reference agents must have matching agents
2. Hook → Script: Hooks in hooks.json must point to existing scripts
3. Command → Tools: Commands must only list valid tool names

Output Format

SCHEMA_CHECK_REPORT
===================

Checked: <number> components
Passed: <number>
Failed: <number>

RESULTS:

[PASS] plugin.json - All required fields present
[PASS] agents/my-agent.md - Valid frontmatter and content
[FAIL] skills/my-skill/SKILL.md - Missing 'triggers' field

ISSUES:
- skills/my-skill/SKILL.md: Missing required 'triggers' field in frontmatter

RECOMMENDATIONS:
- Add triggers field to skills/my-skill/SKILL.md

Transition Conditions

To complete this phase:

1. All checked components must pass validation
2. No critical schema errors
3. Cross-references must be valid

Evidence required for workflow completion:

• checked_count: Number of components validated
• passed_count: Number passing validation
• failed_count: Number failing validation (must be 0)
