Behavior Segmentation

Use this skill when the task is to convert low-level evidence into a timeline of behavior intervals.

Goal

Produce typed behavior segments that are deterministic, reviewable, and compatible with downstream aggregation.

Rules

1. Base segments on signal changes, not narrative intuition.
2. Keep labels canonical and stable across similar clips.
3. Include a concise rationale per segment.
4. Prefer additive evidence such as contact, approach speed, retreat, and zone entry over ambiguous visual impressions.
5. Preserve interval boundaries and frame indices when available.

Aggression-specific guidance

For aggression scoring, focus on canonical sub-events such as:

• slap_in_face
• run_away
• fight_initiation

Normalize common aliases before aggregation.
