Weather-aware morning training brief on your calendar

Build me an agent workflow that runs every weekday at 6am in my local time zone and produces a weather-aware morning training brief, then books the recommended session on my Google Calendar.

Inputs I will configure on the workflow: my home latitude and longitude, my local time zone (e.g. America/New_York), my preferred training windows for the day (default: morning 6am-9am, midday 11am-2pm, evening 5pm-8pm), my Google Calendar ID (default: primary), and an optional notes field describing my current training block (e.g. 'base season', 'taper week').

Each run the agent should:

1. Call Strava's List Athlete Activities operation for the last 7 days (after = now - 7 days) and Get Athlete Stats for the authenticated athlete. Use these to estimate current training load: total time and distance over the last 7 days, count of high-intensity vs easy sessions, days since last rest day, and a rough trend vs my recent totals.

2. Call Weather's Get Weather Forecast operation with my configured latitude and longitude. Inspect today's data points across the three configured windows (morning, midday, evening) for temperature, precipitation probability, precipitation volume, and wind speed. Convert to imperial or metric to match my preference.

3. Synthesize a short brief that decides:

- Sport type (run, ride, swim, strength, cross-train) based on what sports appear in my recent Strava activities and how loaded each one is.

- Intensity (easy, steady, intervals, long, rest) based on accumulated load: high recent load = easy or rest; low load + good weather = key session; very high load or multiple hard days in a row = mandatory rest.

- Window (morning / midday / evening) based on which window has the best conditions: prefer dry, moderate temps, low wind. If every window is poor (heavy rain, dangerous heat or cold, high wind), recommend an indoor swap (treadmill, trainer, pool, strength).

4. Call Google Calendar's Create Event operation on my configured calendar with:

- Summary: a one-line title like 'Easy run, 45 min (morning, 58F clear)'. If it's a rest day, prefix the title with 'Rest day:' and a one-line reason (e.g. 'Rest day: 6 days of training in a row').

- Start and end times matching the chosen window (default 60 minutes; longer for 'long' intensity, shorter for 'easy'). Use RFC3339 with my time zone.

- Description: the full brief, including last-7-day totals, why this sport/intensity was chosen, the forecast for the chosen window, and a 3-5 bullet session structure (warmup, main set, cooldown).

5. Output is one calendar event per weekday. If load and weather together suggest a true rest day, still create a calendar event so the decision is visible, but title it as a rest day and skip the session structure. Never create more than one event per day.

Constraints: do not modify or delete existing events. Do not overwrite events that already exist in the chosen window; if the window is fully booked, fall back to the next-best window and note the change in the description. Keep the brief tight and skimmable, not a wall of text.
