| name | ace-tool |
| description | Semantic codebase search and prompt enhancement via standalone CLI. Use when: (1) Semantic code search with natural language queries, (2) Prompt enhancement with codebase context, (3) Before grep/find/glob operations for better accuracy, (4) Complex requirements clarification, (5) Large codebase navigation. Triggers: "search context", "enhance prompt", "find code that", "clarify requirements". IMPORTANT: Always use ace-tool BEFORE grep/find/glob for semantic-level code location.

ACE-Tool - Semantic Code Search & Prompt Enhancement
High-performance semantic search and AI-powered prompt enhancement. Standalone CLI (no MCP dependency).
Execution Methods
python scripts/ace_cli.py search_context -p /path/to/project -q "function that handles authentication"
python scripts/ace_cli.py enhance_prompt -p "implement login feature" -H "User: what auth method?\nAssistant: JWT"
python scripts/ace_cli.py enhance_prompt --no-interactive -p "implement login feature"
python scripts/ace_cli.py --endpoint claude enhance_prompt -p "implement login feature"
python scripts/ace_cli.py get_config
Tool Routing Policy
Prefer ACE-Tool Over Built-in Tools
| Task | Avoid | Use ACE-Tool CLI |
|---|
| Find function by purpose | grep "def func" | search_context -q "function that..." |
| Locate feature code | find . -name "*.py" | search_context -q "feature description" |
| Clarify requirements | Manual analysis | enhance_prompt -p "requirement" |
| Understand code flow | Multiple grep/read | search_context -q "flow description" |
When to Use Built-in Tools
- Exact string matching (known identifiers)
- File path patterns (known naming conventions)
- Simple text replacement
Command Reference
search_context
Search codebase using natural language descriptions.
python scripts/ace_cli.py search_context -p <project_root> -q <query>
Options:
-p, --project-root Project root path (required)
-q, --query Natural language query (required)
enhance_prompt
Enhance prompts with codebase context and conversation history.
python scripts/ace_cli.py [--endpoint TYPE] enhance_prompt -p <prompt> [options]
Global Options:
--endpoint Endpoint type: new, old, claude, openai, gemini (default: new)
--api-url Override API base URL
--token Override API token
Command Options:
-p, --prompt Original prompt (required)
-H, --history Conversation history: "User: xxx\nAssistant: yyy"
--history-file File containing conversation history
--project-root Project root path (optional)
--no-interactive Disable web UI, output JSON directly
--no-browser Don't auto-open browser, just print URL
--port Port for web server (default: 8765)
get_config
Show current configuration status.
python scripts/ace_cli.py get_config
Interactive Enhancement
Default mode opens web UI with actions:
| Button | Action |
|---|
| Regenerate | Discard current, generate new enhancement from original prompt |
| Refine | Iteratively improve current version, preserving your edits |
| Use Original | Return the original prompt without enhancement |
| Send Enhanced | Confirm and use the current enhanced prompt |
| Cancel | Abort the enhancement process |
Keyboard Shortcuts: Ctrl+Enter Send | Esc Cancel
Workflow
Phase 1: Semantic Search
search_context -p . -q "database connection pooling"
Phase 2: Prompt Enhancement
enhance_prompt -p "optimize query performance"
Error Handling
{"error": "error message", "status_code": 401}
| Error | Recovery |
|---|
| No API configured | Uses local fallback for search_context |
| Token invalid (401) | Check API token |
| Access denied (403) | Token may be disabled |
| Connection timeout | Retries up to 3 times with exponential backoff |
| No results | Broaden search query |
Anti-Patterns
| Prohibited | Correct |
|---|
| Grep before semantic search | Use search_context first |
| Skip prompt enhancement | Use enhance_prompt for complex tasks |
| Ignore conversation history | Include history in enhance_prompt |
| Use exact match for conceptual search | Use natural language query |
| Always use non-interactive mode | Use interactive mode for review |
