Purpose and description
Enable an AI agent to identify an anatomical toe, describe its structure and functional state, and determine what observation or assessment is appropriate.
A toe is a digit of the foot, here understood primarily as one of the five normally present on each human foot, consisting of phalanges and associated joints and soft tissues.
It can be Locate and label a toe using species, foot and digit position.; Record its visible form and measure dimensions using explicit landmarks.; Compare alignment and movement with earlier observations or an identified counterpart.; Document toe contact with the ground, adjacent digits, footwear or other surfaces during a named activity.; Track local skin, nail or claw changes and reported symptoms.; Identify missing information needed before handling, functional assessment or clinical review..
Distinguishing features
The structure is an anatomical digit associated with a foot; an equivalent projection on footwear is a separate object.
It is one digit rather than the entire forefoot or the metatarsal region supporting it.
Its identity follows organism-specific anatomy and position, rather than length alone or assumed human numbering.
A nail, claw or other terminal covering is a component associated with a toe, not the whole toe.
A missing, fused or surgically altered toe remains identifiable through anatomical or clinical evidence even when its usual outline is absent.
Scope
+ Toe identity, species, foot laterality and digit position
+ Boundaries between the toe, its attachment and neighbouring digits
+ Local skeletal, joint, soft-tissue and covering structures
+ Toe movement, contact and contribution to foot function
+ Observed integrity, symptoms and changes over time
- The whole foot, ankle or lower limb as an anatomical system
- Fingers and other digits not identified as foot digits
- Whole-organism gait, balance or neurological status
- Diseases and injuries as independent diagnostic entities
- Footwear, orthoses and prosthetic devices as manufactured objects
- Figurative uses such as the toe of a shoe, slope or tool
Characteristics
- Organism and anatomical convention
- Organism reference, species and cited digit-identification convention Determines which structures, names and functions can be expected.
- Foot and digit identity
- Left, right or unresolved foot; digit designation under the selected convention Distinguishes the target toe from adjacent digits and its opposite-foot counterpart.
- Presence and configuration
- Present, partially absent, absent or unresolved; separate, fused, additional or otherwise altered Prevents ordinary digit count or shape from becoming an identification requirement.
- External dimensions
- Length and width in mm, with anatomical landmarks and measurement posture Supports comparison, accommodation and tracking of local changes.
- Joint alignment and movement
- Joint-specific angles and active or passive movement range in degrees, with posture and method Separates resting position from available movement and records where motion is limited.
- Surface and terminal covering
- Observed skin or other surface integrity; nail or claw presence and condition where applicable Identifies local damage and contact issues without assuming every species has a human-style nail.
- Contact and loading role
- Observed contact during a named activity; supporting, propulsive, grasping, noncontact or unresolved Connects toe structure to demonstrated function in the particular organism.
- Local symptoms and sensation
- Reported pain or altered sensation, observed response, unavailable report or not assessed; include location and time Keeps subjective reports and assessed responses distinct from visual appearance.

Toe identity and boundaries Establishes which anatomical digit is being described and where its ownership ends.
Toe names and boundaries must remain usable across species and anatomical variation.
Organism and digit position
Locates the toe within an identified organism and foot.
Species-specific digit identity
Record the organism, foot and supported digit designation without inferring identity from size alone.
- Which organism, species and foot does this toe belong to? definition
- What anatomical convention or observation supports its digit designation? provenance
Toe attachment and extent
Separates the toe from the supporting foot and adjacent digits.
Proximal boundary and continuity
Make the proximal boundary explicit and record altered attachment, fusion or absence.
- Which landmark defines the proximal limit of this toe for the present observation? boundary
- Is the toe separate, fused, partially absent or otherwise altered, and what evidence establishes that configuration? provenance
Toe anatomy and form Describes the toe's supporting structures, external outline and terminal covering.
A visible toe outline alone cannot establish its internal configuration or distinguish normal variation from change.
Phalanges and articulations
Records supported information about bones, joints and their arrangement.
Skeletal and joint configuration
Distinguish anatomy established for this toe from anatomy expected under a species-level reference.
- Which phalanges and articulations are documented for this toe? definition
- Does that description come from direct assessment, imaging or an anatomical reference? provenance
Toe outline and covering
Records external dimensions and locally applicable skin, pad, nail or claw features.
External form and terminal structures
Describe measurable form and terminal structures without applying human surface anatomy to every organism.
- What are the toe's length and width, and which landmarks and posture define those measurements? measurement
- Which surface and terminal structures are present, and where do they belong within the toe boundary? boundary
Toe motion and contact Connects toe alignment and movement with observed contact during activity.
Toe function depends on joint behaviour and task-specific contact, which cannot be inferred from appearance alone.
Joint position and excursion
Separates resting alignment, active movement and assessed passive movement.
Toe movement profile
Record movement at named joints under stated conditions, including discomfort or constraints.
- What resting alignment and movement range are observed at each assessed toe joint? measurement
- Were the movements active or passive, and under what posture, loading and assessment conditions? provenance
Contact during activity
Records how the toe interacts with support surfaces, adjacent digits and enclosing objects.
Task-specific toe contact
Describe demonstrated contact and contribution during a named activity rather than assigning a universal toe function.
- During which activity does this toe contact a surface, adjacent digit or enclosing object, and at what part of the toe? measurement
- What observation would clarify whether toe contact or restricted clearance is affecting that activity? action
Toe condition and assessment Records local integrity, symptoms, change and the limits of available observations.
An agent needs to distinguish visible changes, reported symptoms and established assessments before deciding what information or assistance is needed.
Local integrity and symptoms
Associates surface changes and symptoms with precise toe locations and evidence types.
Toe-local condition record
Record observed damage, swelling or covering changes separately from reported pain, altered sensation and diagnostic interpretation.
- What changes or symptoms are present, and are they at the tip, joint, underside, side or nail or claw region? measurement
- Which details were directly observed, reported by the individual or established through a qualified assessment? provenance
Change and next assessment
Places current observations against a baseline and identifies unresolved assessment needs.
Toe change and evidence limits
Track change over time while keeping decisions about handling or further assessment tied to available evidence.
- When did the toe's appearance, movement or symptoms change, and what baseline supports that comparison? provenance
- What further information or qualified assessment is needed before handling or testing this toe? 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.

What the second pass must settle
- Does the registry intend human toes specifically, or foot digits across a defined range of animal taxa?
- Which anatomical reference should define the proximal toe boundary and ownership of structures shared with the foot?
- Which species-specific digit conventions and anatomical variations must the initial model support?
- Which measurement protocols provide comparable toe dimensions, alignment and movement across observations?
- Which evidence-based assessment criteria should govern escalation for local toe changes in each supported species and context?
