Changes things 6Claude Code: ask
changelogThe 'what changed & why' feed — the engine's coaching decisions (volume bumps, deloads, swaps) in Coach Fly's voice.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it 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.
meal_planA day of meals hitting the athlete's targets, USDA truth-checked (flags feasible=false with a note when macros are approximate).No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it 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).
nutrition_targetsThe athlete's daily calorie + macro targets, computed from body stats, activity, and goal.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it The athlete's daily calorie + macro targets, computed from body stats, activity, and goal.
readiness_checkinRecord how the athlete feels today (energy, sleep, soreness — each 1–5).No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it 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.
regenerate_programRebuild the whole program from the stored profile (~20s AI generation).No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Rebuild the whole program from the stored profile (~20s AI generation). Use after a profile change or a plateau.
swap_exerciseReplace an exercise with a valid same-area alternative.No findings
Why it is in this group
- The description's first verb is "replace": a word for a change.
Description, as the server wrote it 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).
Only reads 4Claude Code: allow
get_programThe athlete's current multi-day program (render-ready).No findings
Why it is in this group
- The name "get_program" says "get": a word for reading.
Description, as the server wrote it The athlete's current multi-day program (render-ready).
get_todays_sessionToday's workout: exercises, sets/reps, per-exercise load guidance and concrete target weights, plus nutrition targets and cycle status.No findings
Why it is in this group
- The name "get_todays_session" says "get": a word for reading.
Description, as the server wrote it 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.
list_swap_optionsValid alternatives for an exercise — same muscle group, filtered to the athlete's equipment/level/injuries.No findings
Why it is in this group
- The name "list_swap_options" says "list": a word for reading.
Description, as the server wrote it Valid alternatives for an exercise — same muscle group, filtered to the athlete's equipment/level/injuries. Use before swap_exercise.
log_workoutRecord what the athlete actually lifted.No findings
Why it is in this group
- The name "log_workout" says "log": a word for reading.
Description, as the server wrote it 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.
This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
