     - Available on GitHub topic `dsh-plugin`: https://github.com/topics/dsh-plugin
 
-## Exploring code
-- ALWAYS consider `codegraph` and `pnpm dlx @colbymchenry/codegraph` for exploring the code, planning, investigating.
-- `codegraph` helps to search and explore the code graph of the dsh and plugin, which is very useful for understanding the code structure and dependencies.
-- Run `pnpm dlx @colbymchenry/codegraph explore <Query or KeyWords>` to explore the code graph of the dsh and plugin, in the corresponding path of the source code folder.
-  - `pnpm dlx @colbymchenry/codegraph explore --path some-path --max-files 1000 "What's Context Stats?"`
-  - `pnpm dlx @colbymchenry/codegraph query --path some-path --limit 10000 "FileActivity"`
-- Run `pnpm dlx @colbymchenry/codegraph sync` to sync the code graph with the latest code changes, before running the query command.
-- Run `pnpm dlx @colbymchenry/codegraph init` to initialize the code graph for the first time, if the code graph is not initialized yet as no `./.codegraph` folder present.
+## Code Exploration Protocol (Mandatory)
+
+**Prerequisite:** The code graph in the current working directory has already been initialized (`.codegraph` directory exists). **Do not run `init` again.** Use it directly.
+
+### Mandatory Pre-step
+Before any code analysis, exploration, or planning, you **MUST** first use `codegraph` to understand the codebase structure and dependencies. **This step is non-negotiable and cannot be skipped.**
+  ### Usage
+  1. **Explore code structure**
+     ```bash
+     pnpm dlx @colbymchenry/codegraph explore --max-files 1000 "<Query or Keywords>"
+     ```
+  Example:
+     ```bash
+     pnpm dlx @colbymchenry/codegraph explore --max-files 1000 "What's Context Stats?"
+     ```
+  2. **Query specific symbols**
+     ```bash
+     pnpm dlx @colbymchenry/codegraph query --limit 10000 "<SymbolName>"
+     ```
+     Example:
+     ```bash
+     pnpm dlx @colbymchenry/codegraph query --limit 10000 "FileActivity"
+     ```
+     3. **Sync latest changes (only if code has been modified)**
+        ```bash
+        pnpm dlx @colbymchenry/codegraph sync
+        ```
+  
+  ### Execution Order
+  1. Run `codegraph explore` or `codegraph query` to gather code context
+  2. Analyze, plan, or respond based on the returned results
+  3. Run `sync` **only if** the codebase has changed since the last query
 
 ## Coding
 - Always consider the minimal change and the most performance efficient implementation.
