| # MAGAR-Bench task contract |
|
|
| The public input format is shared across all three task families. Each record |
| contains a `messages` array, an `images` array, and metadata. At inference time |
| the assistant message is removed. The model must emit one JSON object only, |
| without Markdown, explanations, wrapper objects, or extra fields. |
|
|
| ## Assembly Decision |
|
|
| Required output fields: |
|
|
| ```json |
| { |
| "operation": "place", |
| "involved_part_ids": ["<part id>"], |
| "next_subgoal": "place base part" |
| } |
| ``` |
|
|
| `operation` is one of `align`, `execute_subtask`, `inspect`, `lock`, `place`, or |
| `recover`. `next_subgoal` is one of the canonical values listed in |
| `schemas/schema.json`. The high-level task ID is metadata and is not part of the |
| model output contract. |
|
|
| ## Atomic Action |
|
|
| Required output is one complete native GUI primitive. The released labels use |
| `click`, `drag`, `hotkey`, `keypress`, and `type_text`. The action type and its |
| parameters must stay together; future actions and action sequences are not |
| allowed. Coordinates are screen pixels when the action requires coordinates. |
|
|
| Examples of the native shapes are: |
|
|
| ```json |
| {"type": "click", "button": "left", "screen_point_px": [320, 240]} |
| ``` |
|
|
| ```json |
| {"type": "keypress", "key": "R"} |
| ``` |
|
|
| ## Minimal Rework |
|
|
| Required output fields: |
|
|
| ```json |
| { |
| "objective": "minimum_distinct_moved_parts", |
| "selected_route_id": "<route id>", |
| "moved_part_ids": ["<part id>"], |
| "min_moved_part_count": 1, |
| "action_ids": ["<action id>"], |
| "full_shortest_path_claim": false |
| } |
| ``` |
|
|
| The moved-part count must equal the cardinality of `moved_part_ids`. The |
| reference is the minimum distinct-part solution inside the validated recovery |
| candidate set for that state. This benchmark does not claim unrestricted |
| global optimality over every possible GUI action sequence. Route and action |
| identifiers are auxiliary recovery information; matching them does not execute |
| the recovery. |
|
|
| ## Split and privacy rules |
|
|
| The 20 Train families and six Test families are disjoint. `data/test_inputs.jsonl` |
| contains no assistant answers or Test targets. The locked Test gold must stay in |
| a separate gated evaluator or private artifact.
