find-CNavMesh_GetNearestNavArea: Скилл поиска в CS2

--- name: find-CNavMesh_GetNearestNavArea description: Find and identify the CNavMesh_GetNearestNavArea function in CS2 binary using IDA Pro MCP. Use this skill when reverse engineering CS2 server.dll or libserver.so to locate the CNavMesh_GetNearestNavArea function by searching for the string "CNavMesh::GetNearestNavArea" and finding the function that references it. disable-model-invocation: true --- # Find CNavMesh_GetNearestNavArea Locate `CNavMesh_GetNearestNavArea` in CS2 server.dll or libserver.so using IDA Pro MCP tools. ## Method ### 1. Search for Signature String Use `find_regex` to search for the debug string: ``` mcp__ida-pro-mcp__find_regex(pattern="CNavMesh::GetNearestNavArea") ``` Expected result: Find string address containing "CNavMesh::GetNearestNavArea" ### 2. Find Cross-References Use `xrefs_to` to find locations that reference this string: ``` mcp__ida-pro-mcp__xrefs_to(addrs="<string_addr>") ``` Expected result: The function that references this string is `CNavMesh_GetNearestNavArea` itself. The string is used as a profiling/debug marker within the function. ### 3. Decompile and Verify Decompile the referencing function to confirm it is `CNavMesh_GetNearestNavArea`: ``` mcp__ida-pro-mcp__decompile(addr="<function_addr>") ``` Verify the function references the `"CNavMesh::GetNearestNavArea"` string (typically as a profiling scope marker). ### 4. Rename the Function ``` mcp__ida-pro-mcp__rename batch={"func": [{"addr": "<function_addr>", "name": "CNavMesh_GetNearestNavArea"}]} ``` ### 5. Generate Signature **ALWAYS** Use SKILL `/generate-signature-for-function` to generate a robust and unique signature for the function. ### 6. Write IDA Analysis Output as YAML **ALWAYS** Use SKILL `/write-func-as-yaml` to write the analysis results. Required parameters: - `func_name`: `CNavMesh_GetNearestNavArea` - `func_addr`: The function address from step 2 - `func_sig`: The validated signature from step 5 ## Function Characteristics - **Type**: Non-virtual (regular) function - **Purpose**: Finds the nearest navigation area to a given position in the navigation mesh. Used for AI pathfinding and navigation queries. ## String References - `"CNavMesh::GetNearestNavArea"` — Debug/profiling marker string directly inside the function ## Output YAML Format The output YAML filename depends on the platform: - `server.dll` → `CNavMesh_GetNearestNavArea.windows.yaml` - `libserver.so` / `libserver.so` → `CNavMesh_GetNearestNavArea.linux.yaml`
