Guided breathing for calm, focus and sleep: a breathing timer in the chat, sleep routines and plans.
Scored across 6 tools
Each tool has a largely distinct trigger: build for multi-day plans, explain for 'what is X', find for describing a feeling, start_breathing_session for a named technique, start_guided_pause for a quick guided break. The main friction is sleep: 'can't sleep' appears under find_breathing_practice, get_sleep_routine, and start_guided_pause's bedtime session, so an agent could plausibly pick the wrong one for a sleep request.
All six names follow a clean snake_case verb_noun pattern (build_, explain_, find_, get_, start_, start_), with the object consistently describing the breathing artifact. Conventions are fully predictable.
Six tools is well within the ideal 3-15 range for a focused breathing/wellness server. Each tool maps to a distinct user intent (plan, explain, match, sleep routine, timer, pause) and none feels redundant.
The surface covers the core lifecycle: explain a technique, choose one, run a timer, get a plan, get a sleep routine, and take a guided pause. Minor gaps remain, such as a way to list available techniques or patterns, or a custom timer, but agents can work around these via explain/find.
Return a 7-day breathing plan for one goal (sleep, stress, anxiety, focus or energy): when to practise, a habit to attach it to, one practice per day that builds gradually, and how to review the week. Each day names the timer that runs it. Use it when the user wants a routine, a habit or a plan over several days rather than one session now. Nothing is saved or scheduled; the user comes back each day. Text only; no timer is shown.
Inputs: goal (required). Returns: days, goal, when, anchor, +1 more
Explain a named breathing technique the way Vayu teaches it: what it is, step-by-step instructions, the best time of day, cautions, and which timer pattern paces it, if any. Use it when the user asks what a technique is or how to do it, including pranayama such as Bhramari, Ujjayi, Nadi Shodhana, Kapalabhati or Bhastrika. Forceful techniques are explained with their cautions but are not paced by the timer. Text only; no timer is shown.
Inputs: technique (required). Returns: name, steps, timer, caution, +6 more
Pick the breathing practice that fits how the user feels right now, explain why, and show it in a timer they can start, with one or two alternatives they can switch to. Use it when the user describes a feeling or a need instead of naming a technique: can't sleep, anxious, a panic moment, stressed, overwhelmed, racing thoughts, brain fog, needing to focus, nerves before a big moment, low energy, a midday slump, starting the day, or wanting to unwind. It is a relaxation exercise, not medical treatment; do not use it for chest pain, fainting, severe breathlessness or another emergency. Nothing is saved.
Inputs: need (required), minutes, time_of_day. Returns: why, need, note, label, +2 more
Return an evening wind-down routine for better sleep, built around Vayu's Bedtime calm practice, and show that practice in a timer: settling prompts, then breathing in for 4 and out for 8. The routine covers a steady wake time, caffeine and alcohol, the last hour before bed, what to do if awake for more than about 20 minutes, a morning check-in, and when to talk to a doctor. Use it when the user wants to sleep better, fall asleep more easily, get back to sleep after waking, or wind down for bed. General wellness guidance, not medical treatment or a diagnosis. Nothing is saved.
Inputs: bedtime, minutes, trouble. Returns: steps, bedtime, trouble, practice, +1 more
Show an interactive timer that paces one named breathing technique for calm, focus or sleep. It is a relaxation exercise, not medical treatment. Use it when the user asks for a specific technique now, such as box breathing, 4-7-8, cyclic sighing, extended exhale, a 4-8 slow exhale, humming bee breath or alternate nostril breathing. The user presses Start in the timer. Nothing is saved and no account is needed.
Inputs: pattern (required), minutes. Returns: name, phases, minutes, pattern, +2 more
Show Vayu's short guided pause in a timer: three settling prompts (settle the body, soften the senses, meet the breath), then a few slow 4-2-4-2 breaths and one release breath. Sessions: morning (start the day), midday (a reset), stress (stress relief) and bedtime (wind down before bed). Use it when the user wants a quick guided break or reset rather than a specific technique. Takes about 1 to 3 minutes. It is a relaxation exercise, not medical treatment. Nothing is saved.
Inputs: session (required), breaths. Returns: session, practice
