# Entity And Key Detail Retrieval

> Use this skill when the user wants questions like 'who exactly', 'which player', 'what number', 'how many', 'which hand', or 'what precise detail at that moment.' Trigger it when the answer depends on retrieving the right person, object, count, or detail from a long clip rather than giving a broad summary.

# 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`

2. **Phase 2: Trajectory Selection**
   Once Phase 1 is complete, read the selection criteria to evaluate the trajectory:
   `references/SELECTION.md`

3. **Phase 3: Data Synthesis**
   Once a trajectory passes Phase 2, read the synthesis instructions to generate the final data:
   `references/SYNTHESIS.md`
