# Variant 1: Minimal
cat > "$RESULTS_DIR/minimal.md" << 'EOF'
# DollhouseMCP Capability Index

ELEMENT_SEARCH_HIERARCHY:
  1. Active - 0 tokens
  2. Local - 50 tokens
  3. GitHub - 100 tokens
  4. Collection - 150 tokens

TOOL_CAPABILITIES:
  search_portfolio: FINDS local elements
  search_collection: FINDS community elements
  get_active_elements: CHECKS active
  activate_element: LOADS element
EOF

# Variant 2: With Hints
cat > "$RESULTS_DIR/with_hints.md" << 'EOF'
# DollhouseMCP Capability Index

Check this index FIRST before using tools.

ELEMENT_SEARCH_HIERARCHY:
  DEFAULT ORDER (when location unspecified):
    1. Active (already loaded) - 0 tokens
    2. Local (~/.dollhouse/portfolio) - 50 tokens
    3. GitHub (user's portfolio) - 100 tokens
    4. Collection (community library) - 150 tokens

  OVERRIDE: Explicit location in query overrides default

TOOL_CAPABILITIES:
  search_portfolio: FINDS elements in local storage
  search_collection: FINDS elements in community library
  portfolio_element_manager: MANAGES GitHub portfolio
  get_active_elements: CHECKS what's currently loaded
  activate_element: LOADS element into context
  create_element: CREATES new element
  edit_element: MODIFIES existing element

WORKFLOW_HINTS:
  For debugging: Check active, then search local, then collection
  For memories: Check if exists first, then edit or create
  For security: Stay local only, never search collection
EOF

# Variant 3: Explicit Process
cat > "$RESULTS_DIR/explicit.md" << 'EOF'
# DollhouseMCP Capability Index

YOU MUST ALWAYS FOLLOW THIS PROCESS:

1. Read the ELEMENT_SEARCH_HIERARCHY
2. Check capabilities in order: Active → Local → GitHub → Collection
3. Use the appropriate TOOL_CAPABILITIES

ELEMENT_SEARCH_HIERARCHY:
  MANDATORY ORDER (unless user specifies location):
    1. Active (get_active_elements) - 0 tokens
    2. Local (search_portfolio) - 50 tokens
    3. GitHub (portfolio_element_manager) - 100 tokens
    4. Collection (search_collection) - 150 tokens

TOOL_CAPABILITIES:
  search_portfolio: SEARCHES local ~/.dollhouse/portfolio
  search_collection: SEARCHES community library
  portfolio_element_manager: SEARCHES GitHub portfolio
  get_active_elements: LISTS currently active elements
  activate_element: ACTIVATES found element
  create_element: CREATES if not found
  edit_element: UPDATES existing element

ELEMENT_CAPABILITIES:
  memories: PROVIDE contextual information
  personas: ALTER behavioral patterns
  skills: EXECUTE specific procedures
  agents: ACHIEVE goal-oriented tasks
  templates: STRUCTURE output formats

INTENT_MAPPING:
  "debug" → search for debug skills/personas
  "memory" → check/create/edit memories
  "security" → local search only
  "git" → search collection for best practices
EOF

# Variant 4: Full Featured
cat > "$RESULTS_DIR/full_featured.md" << 'EOF'
# DollhouseMCP Capability Index

ALWAYS check this index FIRST. It provides 97% token reduction.

## Layer 1: Element Search Hierarchy
ELEMENT_SEARCH_HIERARCHY:
  DEFAULT ORDER (when location unspecified):
    1. Active (already loaded) - 0 tokens
    2. Local (~/.dollhouse/portfolio) - 50 tokens
    3. GitHub (user's portfolio) - 100 tokens
    4. Collection (community library) - 150 tokens

  OVERRIDE: User intent always takes precedence
    - "search the collection for..." → Go directly to collection
    - "check my GitHub for..." → Go directly to GitHub portfolio
    - "look in my local..." → Go directly to local portfolio
    - "is there an active..." → Check only active elements

## Layer 2: Tool Capabilities
TOOL_CAPABILITIES:
  search_portfolio: FINDS elements in local storage
  search_collection: FINDS elements in community library
  portfolio_element_manager: MANAGES GitHub portfolio sync
  get_active_elements: CHECKS what's currently loaded
  activate_element: LOADS element into context
  create_element: CREATES new element
  edit_element: MODIFIES existing element
  list_elements: LISTS available elements by type
  validate_element: VERIFIES element correctness

## Layer 3: Element Capabilities
ELEMENT_CAPABILITIES:
  memories:
    PROVIDE: Contextual information on topics
    PERSIST: Information across sessions
    AUGMENT: Current context with history

  personas:
    ALTER: Behavioral patterns
    PROVIDE: Specialized expertise
    SHAPE: Response style

  skills:
    PROVIDE: Specific capabilities
    EXECUTE: Defined procedures
    ENHANCE: Task performance

## Layer 4: Workflow Processes
WORKFLOW_PROCESSES:
  "I need information about X" →
    FIRST: Check active memories
    THEN: Use search_portfolio
    THEN: Use portfolio_element_manager
    FINALLY: Use search_collection

  "Help me debug" →
    CHECK: Active skills/personas
    SEARCH: Local portfolio
    SEARCH: GitHub portfolio
    SEARCH: Collection

  "Remember this" →
    CHECK: Active memories
    IF_EXISTS: Use edit_element
    IF_NOT: Use create_element
    ENSURE: activate_element

CRITICAL: This index structure provides 97% token reduction compared to loading all elements.
