Skill: entity-and-key-detail-retrieval

1. Capability Definition & Real Case

• Professional Definition: The capability to identify specific entities and recover small but decisive details from the correct temporal window of a long or information-dense video, such as who, which object, what number, what exact body part, or what explicit visual fact matters at a critical moment.
• Dimension Hierarchy: Temporal-Spatial Understanding->Temporal Structure Analysis->entity-and-key-detail-retrieval

Real Case

[Case 1]

• Initial Environment: A full football match video lasting over 100 minutes, with scoreboard overlays and multiple replay cuts. The question targets a specific shot sequence near the 81:38 mark.
• Real Question: How does the goalkeeper prevent Liverpool's shot from scoring at 81:38 in the video?
• Real Trajectory: Navigate to the clue window around 81:38, identify the goalkeeper in the defensive sequence, inspect the saving motion frame by frame, and isolate the exact body part and outcome of the save.
• Real Answer: He uses his right hand to deflect the ball out of bounds.
• Why this demonstrates the capability: The question is not about the whole match; it is about retrieving a very small but decisive detail from the correct segment. It tests whether the agent can first find the right window and then read fine-grained entity-level evidence inside that window.

Pipeline Execution Instructions

To synthesize data for this capability, you must strictly follow a 3-phase pipeline. Do not hallucinate steps. Read the corresponding reference file for each phase sequentially:

1. Phase 1: Environment Exploration

Read the exploration guidelines to discover raw knowledge seeds: references/EXPLORATION.md

1. Phase 2: Trajectory Selection

Once Phase 1 is complete, read the selection criteria to evaluate the trajectory: references/SELECTION.md

1. Phase 3: Data Synthesis

Once a trajectory passes Phase 2, read the synthesis instructions to generate the final data: references/SYNTHESIS.md
