Implementation Reference
- src/server.ts:319-348 (schema)Defines the input schema for the 'trace' tool, specifying parameters such as regexp (required), pkg, ebpf, stack, and pid.
{ name: "trace", description: "Trace program execution", inputSchema: { type: "object", properties: { regexp: { type: "string", description: "Regular expression to match functions to trace" }, pkg: { type: "string", description: "Package to trace (defaults to .)" }, ebpf: { type: "boolean", description: "Use eBPF for tracing (experimental)" }, stack: { type: "number", description: "Show stack trace with given depth" }, pid: { type: "number", description: "Pid to attach to" } }, required: ["regexp"] } }, - src/server.ts:406-407 (registration)Registers the 'trace' tool by routing CallTool requests for 'trace' to the handleDebugCommands function in debug.ts.
if (["debug", "attach", "exec", "test", "core", "dap", "replay", "trace"].includes(name)) { return handleDebugCommands(name, args); - src/types.ts:18-18 (helper)Type definition for DebugSession includes 'trace' as a valid session type.
