Implementation Reference
- src/tools/workouts.ts:277-322 (handler)The core handler function for the 'update-workout' tool. It maps input parameters to the Hevy API request format, calls the updateWorkout method on the Hevy client, handles errors, formats the response using formatWorkout, and returns JSON.
async ({ workoutId, title, description, startTime, endTime, isPrivate, exercises, }) => { const requestBody: PostWorkoutsRequestBody = { workout: { title, description: description || null, startTime, endTime, isPrivate, exercises: exercises.map((exercise: ExerciseInput) => ({ exerciseTemplateId: exercise.exerciseTemplateId, supersetId: exercise.supersetId || null, notes: exercise.notes || null, sets: exercise.sets.map((set: ExerciseSetInput) => ({ type: set.type, weightKg: set.weightKg || null, reps: set.reps || null, distanceMeters: set.distanceMeters || null, durationSeconds: set.durationSeconds || null, rpe: set.rpe || null, customMetric: set.customMetric || null, })), })), }, }; const data = await hevyClient.updateWorkout(workoutId, requestBody); if (!data) { return createEmptyResponse( `Failed to update workout with ID ${workoutId}`, ); } const workout = formatWorkout(data); return createJsonResponse(workout, { pretty: true, indent: 2, }); - src/tools/workouts.ts:248-275 (schema)Zod schema defining the input parameters for the 'update-workout' tool, including workoutId, title, optional description, required ISO timestamps, privacy flag, and array of exercises with detailed set data.
