Implementation Reference
- src/index.ts:892-934 (handler)Main handler function that implements the gdb_next tool logic. Checks for active GDB session, determines 'next' or 'nexti' command based on instructions flag, executes via executeGdbCommand helper, and formats response with output.
private async handleGdbNext(args: any) { const { sessionId, instructions = false } = args; if (!activeSessions.has(sessionId)) { return { content: [ { type: 'text', text: `No active GDB session with ID: ${sessionId}` } ], isError: true }; } const session = activeSessions.get(sessionId)!; try { // Use nexti for instruction-level stepping, otherwise next const command = instructions ? "nexti" : "next"; const output = await this.executeGdbCommand(session, command); return { content: [ { type: 'text', text: `Stepped over ${instructions ? 'instruction' : 'function call'}\n\nOutput:\n${output}` } ] }; } catch (error) { const errorMessage = error instanceof Error ? error.message : String(error); return { content: [ { type: 'text', text: `Failed to step over: ${errorMessage}` } ], isError: true }; } } - src/index.ts:237-254 (registration)Tool registration in the ListToolsRequestSchema handler, defining name, description, and input schema for 'gdb_next'.
