Purpose and description
Enable an AI agent to recognise squash activity, assess playing conditions and match state, and identify appropriate participation, coaching or officiating actions.
Squash is an indoor racket sport in which opposing players or pairs alternately strike a small rubber ball against a front wall within marked boundaries, aiming to prevent a legal return before the ball bounces twice on the floor.
It can be Classify a described activity as squash or flag unresolved confusion with a neighbouring sport.; Check whether the court, equipment and ball behaviour support the intended session.; Track rallies, service and score against an explicitly selected ruleset.; Structure evidence for an interference decision and identify when an authorised official must resolve uncertainty.; Select squash drills targeting shot placement, retrieval, recovery or tactical choice.; Recommend pausing or modifying play when observed court conditions, player readiness or interference create an immediate concern..
Distinguishing features
Participants understand the activity as squash and identify a compatible playing format or governing ruleset; the name alone does not establish the sporting sense.
Opponents share a playing court and direct returns to a front wall rather than exchanging shots across a dividing net.
Legal-return assessment depends on wall and floor contacts, court markings and the permitted bounce sequence.
Movement to retrieve the next shot interacts with an opponent's need for access and swing space, making interference assessment part of play.
Court layout, ball specification, racket specification and service procedure jointly distinguish the selected squash format from racquetball or racketball.
Scope
+ Identification of squash and its singles, doubles and adapted playing formats
+ Court, racket and ball suitability for the intended squash activity
+ Serving, returning, movement and rally progression
+ Scoring, interference decisions and match administration under an identified ruleset
+ Squash-specific skill practice, workload and safe participation
- Squash plants, fruits and food products
- Squash beverages and the general action of crushing or compressing
- Racquetball, racketball and other neighbouring racket sports as independently governed activities
- Court construction engineering and sports equipment manufacturing
- Medical diagnosis, injury treatment and general athlete health management
- Club business operations and tournament commercial management
Characteristics
- Playing format
- Singles, doubles or identified adapted format Determines participant roles, applicable playing arrangements and which comparisons are meaningful.
- Applicable ruleset
- Named governing document, version, effective date and any local modifications Grounds decisions about service, scoring, interference and permitted equipment.
- Court readiness
- Unchecked, ready, restricted or unsuitable, with recorded reasons Connects surface condition, markings, visibility and available space to a decision about starting or continuing play.
- Ball suitability
- Ball specification and observed behaviour relative to players, temperature, warm-up and format Ball behaviour affects rally continuity and the appropriateness of a practice or match.
- Rally state
- Awaiting service, in play, stopped for a decision or concluded Determines whether the next action is a serve, return, adjudication or score update.
- Competitive state
- Points, games, server, service side and match status under the selected ruleset Supports correct continuation without assuming a universal scoring format.
- Interference episode
- Striker, opponent, ball trajectory, access route, swing space, available evidence and decision Allows an agent to distinguish a recorded decision from an uncertain reconstruction.
- Shot outcome
- Recorded shot type, intended target, achieved placement and rally consequence Separates tactical intention from execution and supports focused coaching.
- Rally duration
- Seconds, with explicit start and stop conventions Supports workload assessment and comparison of practice tasks.
- Movement recovery
- Observed recovery position and readiness relative to the next likely return Captures court coverage without treating movement to one fixed location as appropriate after every shot.

Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 9 layers · 16 findings · 30 questions.
Sport identity and format Establishes which sporting sense and playing arrangement the entry represents.
The registry has no definition, and squash shares terminology and playing features with neighbouring activities.
Squash sense and boundaries
Tests whether an observed or described activity belongs to this sporting concept.
Identify squash from combined evidence
Record the participants' terminology, front-wall return pattern, court markings and equipment together; no isolated label or feature should settle an ambiguous identification.
- What evidence establishes that this registry entry denotes the racket sport? definition
- Which observed court, ball or service features distinguish this activity from racquetball or racketball? boundary
Format and rule authority
Connects the session to its participants, format and governing instructions.
Bind the session to applicable rules
Record singles, doubles or adapted play together with the rules document and any agreed modifications before evaluating compliance.
- Which squash format is being played, and how are players assigned to opposing sides? definition
- Which rule version or organiser instruction governs this session? provenance
- Which adaptations change ordinary service, scoring or movement expectations? boundary
Court, ball and readiness Assesses the playing environment and equipment as conditions for squash activity.
Squash depends on playable wall and floor surfaces, meaningful court boundaries and a ball suitable for the participants and conditions.
Court playability
Examines the surfaces, markings and spaces that determine playable returns and movement.
Assess squash court readiness
Record the visibility of service and out markings, relevant front-wall boundaries, floor traction and obstructions before treating a court as ready.
- Are the boundaries needed to judge serves and returns visible and appropriate to the selected format? measurement
- Which surface defects, moisture or obstructions require correction or a pause before play? action
Equipment and ball behaviour
Relates racket condition, ball selection and preparation to the intended activity.
Match equipment to the session
Record racket condition, ball specification, ball preparation and observed bounce rather than inferring suitability solely from a product label.
- What ball specification is in use, and what source explains its intended playing conditions? provenance
- Does the prepared ball support the intended rally task for these players under current conditions? measurement
- What equipment replacement, further preparation or protective equipment is needed before starting? action
Rally and match adjudication Represents legal play, competitive progression and decisions that interrupt or conclude rallies.
A squash agent must connect observed ball and player events to match state while preserving uncertainty in contested decisions.
Service, returns and score
Tracks the events that start, sustain and conclude a rally.
Derive score from rally events
Record service position, striker sequence, relevant wall and floor contacts and the reason a rally ended before updating points, games or service.
- Which observed contact or boundary event establishes whether the serve or return was legal? measurement
- How does the recorded rally outcome change score, server and service side under the selected rules? action
- Which unresolved event prevents a reliable match-state update? boundary
Access, interference and decisions
Examines encounters between an opponent's movement and the striker's opportunity to play the ball.
Record interference before judging
Capture ball position, player paths, access, swing space, efforts to clear and the official's decision, distinguishing observations from interpretations of let, no-let or stroke provisions.
- What evidence shows the striker's access to the ball and available space to make the return? measurement
- Which applicable rule and authorised decision support the recorded interference outcome? provenance
- Should the agent request an official's decision or advise stopping instead of encouraging a potentially unsafe swing? action
Squash performance and practice Connects shot choices, movement and exertion to purposeful squash development.
Useful squash practice requires attention to wall-based placement, shared-court movement and the demands of repeated rallies.
Shot placement and court recovery
Assesses how shot execution and movement influence the next exchange.
Link shot intent to the next position
Record intended and achieved length, width or height, the opponent's resulting options and the player's recovery position; evaluate each in its rally context.
- What was the intended effect of the drive, crosscourt, boast, drop, lob or volley in this rally? definition
- How did actual placement and recovery affect the opponent's next options and the player's retrieval readiness? measurement
- Which constrained drill would address the observed placement or recovery problem? action
Practice demand and progression
Matches squash practice difficulty and rally demands to observed readiness.
Adjust rally demand to readiness
Record drill constraints, rally duration, recovery intervals and signs of deteriorating movement or racket control to guide session adjustments.
- What rally duration, recovery interval and movement pattern does this drill impose? measurement
- Does fatigue coincide with late retrieval, reduced swing control or repeated interference? measurement
- Should the next block change pace, target area, feeding pattern, ball choice or recovery time? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
