task_pages__web_action__action_target_label

Identity

1. Domain: pages
2. Scene id: web_action
3. Source scene: web_action
4. Task id: task_pages__web_action__action_target_label

Contract

1. Objective: identify the candidate-labeled web control matching the visible instruction, guide code, and page context.
2. Public task contract: action_target_label
3. Supported query_id values: click_target_label, type_field_label, select_option_label
4. Answer type: option_letter
5. Annotation schema: bbox
6. Annotation witness: one box covering the selected target control and its candidate label marker.
7. Query argument axes: target control family, target item/section/group context, guide code, target candidate label, web page variant, and style variant.

Program Contract

• web_action_target_control_label(control_family={click_button,input_field,select_option}, instruction_guide_code, page_context); output=option_letter; annotation=bbox(target_control_with_candidate_marker); scene=web_action; scope=one browser-style action-target page

Prompt + Trace

1. Prompt bundle: pages_web_action_v1
2. Scene key: web_action
3. Task key: web_action_query
4. Prompt query keys: click_target_label, type_field_label, select_option_label
5. Runtime query_id is the semantic control-family branch; non-semantic values such as target label, page variant, guide code, and theme are trace metadata.
6. Trace records target control metadata, guide entries, context support, target annotation bbox, sampled scene/style metadata, and prompt metadata.
