List the rider's Rouvy Activities, newest first, as compact rows (id, title, type, start, moving time, distance, elevation, TSS, IF). Use the ids with the other tools.

One Activity's summary, with Rouvy's own numbers (they match the Rouvy app): times, distance, elevation, kcal, NP, IF, TSS, power peaks, min/max/avg power, heart rate, cadence and speed, %FTP, time in power and HR zones, laps and route segment results. Also the Rider settings used (FTP, weight, max HR, zones) from the Activity snapshot, which data exist, and a note for each value left out.

Fixed-size splits of one Activity (every 5 min by default), from its per-second Activity file. For each split: start/end second, avg, NP and max power, avg power as %FTP, avg/max heart rate, avg cadence, avg speed, distance and climbing. %FTP uses the FTP from the Activity snapshot. A note says why any stat is left out.

Stats for one stretch of an Activity (e.g. a climb from 20:00 to 35:00), from its per-second Activity file: the same stats as one split of get_activity_intervals, plus the best efforts (peak powers for the durations that fit), the first half vs the second half, and HR:power decoupling between them. %FTP uses the FTP from the Activity snapshot. A note says why any stat is left out.

Downsampled per-second data of one Activity, from its Activity file, to chart or reason about: one array per field, each value the mean of one bucket of resolution_sec_used seconds from start_sec (the last bucket may be shorter). Units: power W, heart_rate bpm, cadence rpm, speed m/s, altitude m, distance m from the start. At most 500 points per field: a finer request is served at the smallest resolution that fits. A field the Activity doesn't have is listed in missing_fields; a bucket with no data is null.

List the rider's own Workouts in their Rouvy library (the plans, not the rides), newest first, as compact rows (id, name, duration, TSS, difficulty, tags, number of Steps). Use get_workout for the Steps.

One of the rider's own Workouts: name, description, tags, visibility, duration, TSS, IF, difficulty, route, its Steps (steady, ramp or free ride, in % FTP, with an optional cadence range) and Cues (text at a time from the start). Also rider_ftp_w, the rider's current FTP in watts, to turn watts into % FTP.

Create a Workout in the rider's Rouvy library, only when they ask for one. Steps are steady, ramp or free ride, in % FTP (use get_workout's rider_ftp_w to convert watts), each with an optional cadence range; repeat a block with a repeat Step. Private unless the rider asks for public. Returns the saved Workout as Rouvy has it. If it says the outcome is unknown, call list_workouts before trying again.

Change one of the rider's own Workouts, only when they ask. Give only what changes: steps, when given, replace all Steps; every field left out (cues included) keeps its current value; the route is kept. A get_workout result can be edited and passed back as is. Warning: a Workout synced from another app (TrainingPeaks, Intervals.icu…) may be overwritten by that app's next sync. Returns the saved Workout.

Delete one of the rider's own Workouts from their Rouvy library, only when they ask, and check it's gone. Warning: a Workout synced from another app (TrainingPeaks, Intervals.icu…) may come back with that app's next sync. Returns the deleted Workout's id and name.

Save one Activity to the rider's export folder: its Activity file as downloaded from Rouvy (fit), or its per-second records as CSV (csv). Overwrites an earlier export of the same Activity and returns the file's absolute path.
