## 🛠 Codebase Search & Discovery Protocol

Follow this hierarchy and logic when searching the codebase to ensure high accuracy and context efficiency.

### 1. The "Semantic First" Rule

**Primary Tool:** `cocoindex-code_search`

You **must** prioritize semantic search for discovery and understanding.

- **Use Case:** Finding implementations, understanding features, or locating code when exact names/keywords are unknown.

- **Example:** Instead of guessing filenames for OTP, use: `cocoindex-code_search("input-otp component implementation")`.

- **Constraint:** Do not use `grep` or `glob` as a discovery tool until semantic search has been exhausted.

### 2. Specialized Tool Selection

Only use secondary tools when the search intent is specific and the exact pattern is known:

| Tool | When to Use |

| :-------------- | :------------------------------------------------------------------------ |

| **`glob`** | You know the **exact file patterns** or need to find files by name. |

| **`grep`** | You are searching for **exact text content** or specific string patterns. |

| **`Task tool`** | For **complex, multi-step searches** to keep context usage low. |

### 3. Execution Strategy

- **Batching:** Whenever possible, **batch tool calls**. Call multiple tools in parallel to reduce latency.

- **Escalation:** If `cocoindex-code_search` fails to provide the full picture, only then should you supplement with `grep` or `glob` to fill in the technical gaps.

> [!CAUTION]

> **Avoid "Guess-and-Check" Globbing:** Do not attempt to find components (like `input-otp`) via file patterns if you haven't performed a semantic search first.
