/briefing — Post Coaching Note to Calendar

Creates a NOTE event on the Intervals.icu calendar with a coaching summary for today. The note appears alongside your planned workout — visible in Intervals.icu and any synced calendar (Google, Apple, Outlook).

Step 1: Read knowledge base

Read knowledge/recovery-overtraining.md and knowledge/workout-types.md to inform the coaching note with relevant training science.

Step 2: Gather data

Fetch data using MCP tools (call them directly, in parallel where possible):

• Events endpoint for today (oldest=today, newest=today) — planned workouts
• Wellness endpoint for today (oldest=today, newest=today) — sleep, HRV, RHR, fatigue, mood
• Fitness endpoint for the last 7 days — CTL/ATL/TSB trend
• Zones are cached in athlete/profile.md — skip the athlete endpoint unless zones are missing

Step 3: Write the coaching note

Compose a concise, actionable coaching note. Keep it short — this will be read on a calendar card, not a terminal. Structure:

[Wellness] Sleep Xh | HRV XX (vs avg XX) | RHR XX
[Form] TSB X (fresh/neutral/tired/fatigued) — CTL XX, ATL XX
[Today] {workout name}: {brief coaching cue for execution}
{one-line recommendation or flag if anything needs attention}

Guidelines:

• If wellness data suggests caution (poor sleep, low HRV, high fatigue), say so directly
• If the workout has structured intervals, include the key intensity targets using the athlete's actual zones
• If it's a rest day, note it and mention what's coming next
• Keep the entire note under ~150 words — it needs to fit a calendar card
• No greetings, no sign-offs — just the coaching content

Step 4: Post to calendar

Call the create event endpoint with:

• category: "NOTE"
• start_date_local: today's date in YYYY-MM-DD format
• name: "Coach's Notes"
• description: the coaching note from Step 2

Step 5: Confirm

Tell the user the note has been posted. Mention that it will show up in Intervals.icu and any synced calendars.
