工具清单
工具（10）
🟢get_todays_session(dayIndex)
Today's workout: exercises, sets/reps, per-exercise load guidance and concrete target weights, plus nutrition targets and cycle status. Auto-applies the user's readiness check-in (autoregulation) if they've done one today. Call this to see what the athlete should do now.

"properties": {
"dayIndex": {
"description": "Which program day (1-based). Defaults to the first day.",
"type": "integer",

}
},
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢readiness_checkin(energy, sleep, soreness)
Record how the athlete feels today (energy, sleep, soreness — each 1–5). The engine scores readiness and, on the next get_todays_session, reshapes the workout accordingly (reduce volume / reduce intensity / recovery day). Returns the readiness score + modifier.

}
},
"required": [
"energy",
"sleep",
"soreness"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}⚪log_workout(dayIndex, goal, exercises)
Record what the athlete actually lifted. The engine runs progression (double-progression, e1RM), detects PRs, and returns per-exercise outcomes (established/progressed/held/deloaded) with next-time targets. Weights are in kg.

}🟢list_swap_options(exerciseId)
Valid alternatives for an exercise — same muscle group, filtered to the athlete's equipment/level/injuries. Use before swap_exercise.

}⚪swap_exercise(exerciseId, toExerciseId, dayIndex, scope)
Replace an exercise with a valid same-area alternative. scope 'today' = just this session; scope 'program' = going forward. The new lift starts fresh (day-one calibration).

{
"type": "object",

}⚪meal_plan(mealsPerDay, trainingDay, dietaryStyle, exclusions)
A day of meals hitting the athlete's targets, USDA truth-checked (flags feasible=false with a note when macros are approximate). Slow (~15s AI call).

The 'what changed & why' feed — the engine's coaching decisions (volume bumps, deloads, swaps) in Coach Fly's voice. Use to explain to the athlete why their plan evolved.
