name	find-CBasePlayerController_HandleCommand_JoinTeam
description	Find and identify the CBasePlayerController_HandleCommand_JoinTeam function in CS2 binary using IDA Pro MCP. Use this skill when reverse engineering CS2 server.dll or server.so to locate the HandleCommand_JoinTeam function by searching for known debug string references and analyzing cross-references.

Find CBasePlayerController_HandleCommand_JoinTeam

Locate CBasePlayerController_HandleCommand_JoinTeam in CS2 server.dll or server.so using IDA Pro MCP tools.

Method

1. Search for the debug string:

   mcp__ida-pro-mcp__find_regex pattern="HandleCommand_JoinTeam\( %d \) - invalid"
   

2. Get cross-references to the string:

   mcp__ida-pro-mcp__xrefs_to addrs="<string_addr>"
   

3. Decompile the referencing function:

   mcp__ida-pro-mcp__decompile addr="<function_addr>"
   

4. Rename the function:

   mcp__ida-pro-mcp__rename batch={"func": [{"addr": "<function_addr>", "name": "CBasePlayerController_HandleCommand_JoinTeam"}]}
   

5. Generate and validate unique 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 beside the binary:

   ALWAYS Use SKILL /write-func-ida-analysis-output-as-yaml to write the analysis results.

   Required parameters:

   • func_name: CBasePlayerController_HandleCommand_JoinTeam
   • func_addr: The function address from step 3
   • func_sig: The validated signature from step 6

Signature Pattern

The function contains a debug warning call with format string:

HandleCommand_JoinTeam( %d ) - invalid team index.

Function Characteristics

• Prototype: bool CBasePlayerController::HandleCommand_JoinTeam(CBasePlayerController *pPlayerController, int teamIndex, bool bQueue)
• Parameters:
  • this: CBasePlayerController pointer
  • teamIndex: The target team index
  • bQueue: Whether to queue the team change
• Return: bool indicating success/failure

Team IDs

• 0: Unassigned
• 1: Spectator
• 2: Terrorist
• 3: Counter-Terrorist

Output YAML Format

The output YAML filename depends on the platform:

• server.dll → CBasePlayerController_HandleCommand_JoinTeam.windows.yaml
• server.so → CBasePlayerController_HandleCommand_JoinTeam.linux.yaml
