Intervals Agent

Analyze activity

Review a completed ride or workout rep-by-rep, compare a session across its history, or interpret wellness and readiness data (TSB, CTL/ATL, sleep, HRV). Load when the athlete asks how a ride went, to compare two or more sessions, or to read their current fatigue/readiness.

Build athlete profile

Onboard a new athlete: interview them and build their coaching profile from scratch. Load on the first interaction when no /profile exists yet, or when rebuilding the profile.

Fix activity data

Correct a completed activity's recorded sensor data: rescale a stream (power/cadence/HR/altitude/speed) or fill short dropouts. Destructive and irreversible. Load only when the athlete explicitly asks to fix, rescale, or clean up recorded data.

Plan workout

Design, schedule, and post a workout end to end — fetch training, wellness, and calendar context, design the session, verify metrics, preview, and post on approval. Load whenever the athlete asks to plan, create, move, or replace a workout for today or any other day.

Polish activity feed

Polish a freshly landed activity's public title and description for the athlete's activity-feed agent (e.g. Strava), using the same analysis as a workout review. Load after an activity syncs from a head unit/watch and the athlete wants it written up.

Power curves and eftp

Answer questions about best-effort power, HR, or pace curves and eFTP: peak or sustained capability over a date range (e.g. 'best 5-min power this season', 'estimate my eFTP', 'my pace curve'). Load for capability/ceiling questions rather than single-ride review.

Get current time

Return the current wall-clock time. Use this when reasoning about elapsed time (e.g. current minute of a live match, time until a deadline) or about what day it is — don't guess the time or the date. By default `now_iso` and `local_date` are in the user's own timezone (near midnight the UTC date is a day ahead of the user's local date). Pass `timezone` (an IANA name like 'Europe/Berlin') only to override that, e.g. to read the time in another location.

Compute workout metrics

Compute TSS, IF, and duration for a workout description using the same deterministic parser used in the preview. Call this after drafting a workout to verify it hits your targets before calling create_calendar_event. If the result is off, revise the workout and recheck — but limit self-correction to 3 attempts; if you can't converge, go with the closest result and note the discrepancy.
