Enable an AI agent to recognise a lacrosse activity, assess its playing and readiness state, and identify permitted next actions under the applicable format and rules.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a lacrosse activity, assess its playing and readiness state, and identify permitted next actions under the applicable format and rules.
It can be Classify a lacrosse match, session or drill and resolve its applicable rules profile.; Check whether the playing area, player configuration and equipment support starting or resuming play.; Record passes, catches, carries, shots, loose-ball contests and changes of control.; Evaluate a proposed movement, stick action, contact or substitution against the applicable restrictions.; Identify the restart, sanction or unresolved ruling associated with a stoppage.; Reconstruct the current score, possession, numerical balance and clock state from recorded events..
Distinguishing features
The activity centres on controlling a ball with a pocketed, netted stick called a crosse; record modified forms explicitly.
Its playing objective involves opposing goals, or a drill practising skills toward that objective, rather than advancing toward a wicket, basket or end zone.
The control mechanism distinguishes it from hockey: the crosse pocket supports carrying, catching and throwing rather than relying principally on a blade or striking face.
Field, box and sixes labels must be resolved into an actual rules profile; surface, team composition and contact permissions cannot safely be inferred from the word lacrosse alone.
A reduced drill remains identifiable through lacrosse equipment, techniques and its connection to lacrosse play even when it omits goals or full teams.
Scope
+ Activity format, governing rules and distinctions between matches, practices and drills
+ Sides, player roles, participation eligibility and substitutions

+ Possession, ball location, scoring, timing and restarts
+ Permitted stick use, contact, infringements and restrictions on participation
- Athlete identity, medical diagnosis and long-term training history
- Club governance, contracts and team finances
- Tournament administration and season standings
- Venue ownership, maintenance and spectator operations
- Equipment manufacturing, retail inventory and procurement
Characteristics
- Activity mode
- match | practice | drill | modified game Determines whether full competition requirements apply or selected skills and constraints define the activity.
- Format and participation division
- Declared format, division and any adaptation Prevents assumptions about player numbers, stick configurations and contact permissions from crossing between variants.
- Applicable rules profile
- Governing authority, rule document, edition and local modifications Provides the basis for deciding whether an action, setup or outcome is valid.
- Active player configuration
- Players on each side, assigned roles and temporary participation restrictions Supports checks on legal participation, substitution and numerical advantages.
- Playing area geometry
- Dimensions and positions in metres, with named markings and zones Locates boundaries, goals and restricted areas needed to interpret movement and scoring.
- Equipment conformity
- For each relevant item: verified conforming | nonconforming | unverified Makes readiness depend on the actual crosse, ball and protective equipment requirements.
- Ball control state
- Controlled by identified player | loose | out of play | unresolved Distinguishes possession from proximity and constrains possible next actions.
- Ball and player positions
- Coordinates in metres or named zones, with observation time Supports boundary, crease, positioning and restart decisions.
- Play phase
- Preparation | live play | stoppage | restart pending | interval | complete Determines whether movement, substitutions and other actions can take effect.
- Score and clock state
- Awarded goals by side; period; clock readings in seconds where applicable Separates confirmed scoring from attempts and supports time-dependent decisions.
- Outstanding rulings and sanctions
- Pending decisions, awarded restarts and participant restrictions with release conditions Preserves obligations that remain active after an infringement or stoppage.

Lacrosse identity and rules Establishes which lacrosse activity is being represented and which rules govern its interpretation.
Lacrosse variants share equipment and skills but do not support a single assumed set of participation and play restrictions.
Activity and format
Identifies the format and whether the activity is competition, training or an adaptation.
Declared lacrosse form
Records the declared format and the features connecting the observed activity to lacrosse.
- Is this field, box, sixes or another declared lacrosse format, and is it a match, practice or drill? definition
- Which equipment, techniques or playing objectives establish that a modified activity is still lacrosse? boundary
Rule authority
Connects interpretation to a specific rules edition and declared modifications.
Applicable rule basis
Records the authority and scope of the rules used for this activity without silently importing another variant's requirements.
- Which governing document, edition and division-specific provisions apply? provenance
- Which local or drill modifications change player numbers, equipment, contact or scoring, and who authorised them? provenance
Players and participation Represents opposing sides, lacrosse roles and changes in active participation.
The legality of positioning and actions can depend on role, goalkeeper status and the number of players currently permitted to participate.
Sides and roles
Identifies active players and distinguishes tactical assignments from rule-defined roles.
Active role configuration
Records each side's active players, goalkeeper designation where applicable and relevant role restrictions.
- Which players are active for each side, and which have goalkeeper or other rule-defined status? definition
- Which recorded positions are tactical assignments, and which impose movement, equipment or participation restrictions? boundary
Substitution and player balance
Tracks entries, exits and temporary changes to the players available on the playing area.
Legal participation transitions
Connects substitutions and sanctions to the current legal player configuration.
- May the proposed player enter now, through which location, and subject to whose exit or release? action
- How many players may each side currently field, and which restrictions explain any numerical difference? measurement
Playing space and equipment Represents the physical setup through the features needed to conduct and interpret lacrosse play.
Goal geometry, crease boundaries, crosse configuration and protective equipment affect what play is possible and permitted.
Goals, boundaries and zones
Locates the goals and spatial restrictions relevant to the selected format.
Lacrosse playing geometry
Records the playing surface, goals, creases, boundaries and any other rule-relevant markings or enclosure features.
- Where are the goal lines, creases, playing boundaries and other required zones in this setup? measurement
- How do the applicable rules treat contact with lines, boards or areas outside the playing boundary? boundary
Crosses, ball and protection
Captures equipment requirements by format and player role.
Equipment readiness
Records whether the crosses, ball, goals and required protective items have been checked against the applicable requirements.
- Which crosse dimensions, pocket properties, ball properties and protective items require verification for each role? measurement
- Which equipment defects or failed checks require correction before a player or the activity may continue? action
Ball play and match progress Represents control of the ball, lacrosse actions and progress toward a confirmed result.
An agent must distinguish possession, loose-ball play and scoring attempts while retaining enough timing context to interpret them.
Control and ball actions
Tracks who controls the ball and how that control changes through lacrosse play.
Possession and action sequence
Records carries, passes, catches, shots, interceptions and loose-ball recoveries with their observed outcomes.
- Who controls the ball, or is it loose, out of play or insufficiently observed? measurement
- What observed event establishes that a pass, catch, shot or recovery changed the ball's control state? provenance
Goals, periods and clocks
Separates scoring observations from awarded goals and tracks applicable timing constraints.
Confirmed progress state
Records awarded goals, period progress and applicable game or possession clocks, including unresolved decisions.
- Was the apparent goal awarded, disallowed or left pending, and which decision supports that status? provenance
- What are the current score, period and applicable clock readings, including whether each clock is running? measurement
- Which event starts, stops or resets each applicable clock? definition
Legal actions and restarts Connects lacrosse-specific action restrictions to rulings, stoppages and resumption of play.
Stick use, player contact, crease access and restart procedures require explicit format-sensitive decisions.
Stick, contact and position restrictions
Evaluates proposed actions in relation to the players, ball and restricted spaces.
Action permission context
Captures the circumstances required to assess a stick check, body contact, crease entry or restricted-area movement.
- For a proposed check or contact, what target, direction, force, ball proximity and player status must the applicable rules consider? action
- May this player enter or remain in the relevant crease or restricted zone in the current phase of play? boundary
Rulings, sanctions and resumption
Records what a stoppage requires before legal play can resume.
Restart and sanction obligations
Connects the reason for a stoppage to the awarded restart, participant placement and outstanding sanctions.
- Which restart procedure applies, where does it occur, and who may possess or contest the ball? action
- Which sanctions remain active, and what timing or event conditions release the affected players? definition
- What player placement, equipment correction or official signal is required before play resumes? action
What the second pass must settle
- Does the registry intend lacrosse to include all traditional and contemporary forms, or should some be related to this entry through separately governed models?
- Which authoritative rule documents and editions should anchor the initial format and division profiles?
- Which concepts of possession, checking, crease access and restart can be shared across profiles without obscuring material differences?
- How should informal sessions and adaptive forms declare modified equipment and contact rules when no published governing document applies?
- What evidence should resolve conflicts between observed events, official rulings and later corrections to score or timing?
