MOT - System Health Check

Run comprehensive health checks on all Claude Code components.

Usage

/mot              # Full audit (all categories)
/mot skills       # Just skills
/mot agents       # Just agents
/mot hooks        # Just hooks
/mot memory       # Just memory system
/mot --fix        # Auto-fix simple issues
/mot --quick      # P0 checks only (fast)

Audit Process

Phase 1: Skills Audit

# Count skills
echo "=== SKILLS ==="
SKILL_COUNT=$(find .claude/skills -name "SKILL.md" | wc -l | xargs)
echo "Found $SKILL_COUNT skill files"

# Check frontmatter parsing
FAIL=0
for skill in $(find .claude/skills -name "SKILL.md"); do
  if ! head -1 "$skill" | grep -q "^---$"; then
    echo "FAIL: No frontmatter: $skill"
    FAIL=$((FAIL+1))
  fi
done
echo "Frontmatter: $((SKILL_COUNT - FAIL)) pass, $FAIL fail"

# Check name matches directory
FAIL=0
for skill in $(find .claude/skills -name "SKILL.md"); do
  dir=$(basename $(dirname "$skill"))
  name=$(grep "^name:" "$skill" 2>/dev/null | head -1 | cut -d: -f2 | xargs)
  if [ -n "$name" ] && [ "$dir" != "$name" ]; then
    echo "FAIL: Name mismatch $dir vs $name"
    FAIL=$((FAIL+1))
  fi
done
echo "Name consistency: $((SKILL_COUNT - FAIL)) pass, $FAIL fail"

Phase 2: Agents Audit

echo "=== AGENTS ==="
AGENT_COUNT=$(ls .claude/agents/*.md 2>/dev/null | wc -l | xargs)
echo "Found $AGENT_COUNT agent files"

# Check required fields
FAIL=0

  # Check name field exists
  if ! grep -q "^name:" "$agent"; then
    echo "FAIL: Missing name: $agent"
    FAIL=$((FAIL+1))

  fi

  # Check model is valid

  case "$model" in
    opus|sonnet|haiku) ;;
    *) echo "FAIL: Invalid model '$model': $agent"; FAIL=$((FAIL+1)) ;;
  esac
done
echo "Agent validation: $((AGENT_COUNT - FAIL)) pass, $FAIL fail"

# Check for dangling references (agents that reference non-existent agents)
echo "Checking agent cross-references..."

  [ -f "$agent" ] || continue
  # Find subagent_type references

  for ref in $refs; do
    if [ ! -f ".claude/agents/$ref.md" ]; then
      echo "WARN: $agent references non-existent agent: $ref"
    fi

done

Phase 3: Hooks Audit

echo "=== HOOKS ==="

# Check TypeScript source count
TS_COUNT=$(ls .claude/hooks/src/*.ts 2>/dev/null | wc -l | xargs)

    echo "FAIL: Not executable: $sh"
    FAIL=$((FAIL+1))
  fi
done
SH_COUNT=$(ls .claude/hooks/*.sh 2>/dev/null | wc -l | xargs)
echo "Shell wrappers: $((SH_COUNT - FAIL)) executable, $FAIL need chmod +x"

# Check hooks registered in settings.json exist
echo "Checking registered hooks..."
FAIL=0
# Extract hook commands from settings.json and verify files exist
grep -oE '"command":\s*"[^"]*\.sh"' .claude/settings.json 2>/dev/null | \
  sed 's/.*"\([^"]*\.sh\)".*/\1/' | \

Phase 4: Memory Audit

echo "=== MEMORY SYSTEM ==="

# Check DATABASE_URL

  echo "FAIL: DATABASE_URL not set"

  echo "PASS: DATABASE_URL is set"

  # Test connection

fi

# Check Python dependencies
echo "Checking Python dependencies..."
(cd opc && uv run python -c "import psycopg2; import pgvector; import sentence_transformers" 2>/dev/null) && \
  echo "PASS: Python dependencies available" || \
  echo "WARN: Some Python dependencies missing"

Phase 5: Cross-Reference Audit

echo "=== CROSS-REFERENCES ==="

# Check skills reference valid agents
echo "Checking skill → agent references..."
FAIL=0
for skill in $(find .claude/skills -name "SKILL.md"); do
  refs=$(grep -oE 'subagent_type[=:]["'\'']*([a-z-]+)' "$skill" 2>/dev/null | sed 's/.*["'\'']//' | sed 's/["'\'']$//')
  for ref in $refs; do
    if [ -n "$ref" ] && [ ! -f ".claude/agents/$ref.md" ]; then
      echo "FAIL: $skill references missing agent: $ref"
      FAIL=$((FAIL+1))
    fi
  done
done
echo "Skill→Agent refs: $FAIL broken"

Auto-Fix (--fix flag)

If --fix is specified, automatically fix:

1. Make shell wrappers executable

   chmod +x .claude/hooks/*.sh
   

2. Rebuild hooks if TypeScript newer than bundles

   cd .claude/hooks && npm run build
   

3. Create missing cache directories

   mkdir -p .claude/cache/agents/{scout,kraken,oracle,spark}
   mkdir -p .claude/cache/mot

## Summary
| Category | Pass | Fail | Warn |
|----------|------|------|------|
| Skills   | 204  | 2    | 0    |
| Agents   | 47   | 1    | 3    |
| Hooks    | 58   | 2    | 1    |
| Memory   | 4    | 0    | 1    |
| X-Refs   | 0    | 0    | 2    |

## Issues Found

### P0 - Critical
- [FAIL] Hook build failed: tldr-context-inject.ts

### P1 - High
- [FAIL] Agent references missing: scot → scout (typo)

### P2 - Medium
- [WARN] 3 hooks need rebuild (dist older than src)

### P3 - Low
- [INFO] VOYAGE_API_KEY not set (using local BGE)

Exit Codes

• 0 - All P0/P1 checks pass
• 1 - Any P0/P1 failure
• 2 - Only P2/P3 warnings

Quick Mode (--quick)

Only run P0 checks:

1. Frontmatter parses
2. Hooks build
3. Shell wrappers executable
4. PostgreSQL reachable
