/ork:doctor           # Standard health check
/ork:doctor -v        # Verbose output
/ork:doctor --json    # Machine-readable for CI

# Detection logic:
# - Scans for .claude-plugin/plugin.json in plugin paths
# - Identifies orkl or ork
# - Counts skills/agents per installed plugin

# Checks performed:
# - SKILL.md frontmatter (name, description, user-invocable)
# - context: fork field (required for CC 2.1.0+)
# - Token budget compliance (300-5000 tokens)
# - Internal link validation (references/ paths)
# - Related Skills references exist

# Checks performed:
# - Frontmatter fields (name, description, model, tools, skills)
# - Model validation (opus, sonnet, haiku only)
# - Skills references exist in src/skills/
# - Tools are valid CC tools

# Checks performed:
# - hooks.json schema valid
# - Bundle files exist (12 .mjs bundles)
# - Async hooks use fire-and-forget pattern (9 async)
# - Background hook metrics health (Issue #243)
# - Windows-safe spawning (PR #645)

# Automated checks:
# - Graph: .claude/memory/ exists, decisions.jsonl valid JSONL, queue depth

# Run these commands to gather memory health data:
wc -l .claude/memory/decisions.jsonl 2>/dev/null || echo "No decisions yet"
wc -l .claude/memory/graph-queue.jsonl 2>/dev/null || echo "No graph queue"
ls -la .claude/memory/ 2>/dev/null || echo "Memory directory missing"

# Checks performed:
# - plugins/ generated from src/
# - Manifest counts match actual files
# - No orphaned skills/agents

# Checks performed:
# - agent-browser: installed globally via skills CLI
# - Validates symlink exists at ~/.claude/skills/agent-browser

# Checks performed:
# - Parse .mcp.json, list each server with enabled/disabled state
# - For tavily: check TAVILY_API_KEY env var OR op CLI availability
# - For memory: check MEMORY_FILE path is writable
# - For agentation: check agentation-mcp package is installed (npx --yes dry-run)
# - Flag any enabled MCP whose process would likely fail at startup

MCP Servers:

- memory:             enabled  ✓
- sequential-thinking: disabled ○
- tavily:             disabled ○  (enable: set TAVILY_API_KEY, see /ork:configure)

                                  Fix: set TAVILY_API_KEY or set "disabled": true in .mcp.json

MCP Servers:
- agentation:         enabled  ✗  agentation-mcp package not found
                                  Fix: npm install -D agentation-mcp  or  set "disabled": true
