DEPRECATED since 2026-09-27, kept until at least 2026-10-27: the edit ops are split by cost between two tools, one for the free deterministic ops and one for the paid LLM re-authoring ops (invocableVia in the op catalogue names them). This alias routes each op to the tool that owns it and answers what that tool answers, plus a deprecated notice that names it. Ops:

• assign_material_to_shot: Puts a piece of the person's own library material (its asset_id: a photo or a video they uploaded) on one shot of a scene, by default the base shot that is the scene's visual; the edit mounts it as is, with nothing bought or searched. Deterministic, $0. Args: scene_index, asset_id (the assetId of the person's own material in the piece), shot_index? (0-based; default the base shot, which is the scene's visual), shows? (what the material shows, in English; the shot's brief only when the scene has no shot list yet), source_start_sec? (second of the video the shot enters from); only on an ai_image, ai_video or archive scene.

• assign_narration_to_scene: Sets a segment (from_sec-to_sec) of the person's own recording (its asset_id: an audio file, or the sound of a video they uploaded) as the VOICE of one scene; with with_picture that video is also the scene's picture, tied to its voice. The voice is cut from the recording at the next build, not synthesized, and a voice regeneration keeps it. Deterministic, $0. Args: scene_index, asset_id (the assetId of the person's own recording in the piece: an audio file, or a video whose sound is the voice), from_sec, to_sec (the segment, in seconds from the start of the recording), with_picture? (video only: the same segment is also the scene's picture, tied to its voice; only on an ai_image, ai_video or archive scene). The voice is cut from the recording at the next build, not synthesized.

• remove_narration_from_scene: Returns one scene to the cast voice: the person's own recording it spoke with is taken away. Deterministic, $0. Args: scene_index (the scene goes back to the cast voice).

• replan_scenes: Reorder the scenes (a permutation of indexes). Deterministic, $0. Args: order=[int...].

• revestir_como_autor: Re-dress ONE scene's visual as an animated author's scene (a world with an actor where the data lives), keeping the narration word for word; for a still image held too long. LLM. Args: scene_index, brief? (only the VISUAL is re-dressed as an animated author's scene by the piece's director; the narration stays word for word, so the voice is reused; brief orients the world/actor).

• rewrite_scene: Re-author one scene (script and visual) under a brief. LLM. Args: scene_index, brief (the WHOLE scene is re-authored under the brief).

• set_piece_fields: Set PIECE-level fields (production_score: silence_plan, music_intent, narrative_arc…), validated by the schema. Deterministic, $0. Args: fields (partial production_score: silence_plan, music_intent, narrative_arc, expected_total_duration_sec…; lists replace).

• set_scene_fields: Set concrete fields of one scene (narration, duration, silences, infographic data…), validated by the schema. Deterministic, $0. Args: scene_index, fields (partial scene object: narrator_text, direction_notes, pre_silence_sec, pause_after_sec, visual.duration_target_sec, visual.prompt, infographic.data, kinetic_caption…; nested dicts merge by key, null deletes; validated by the VBP schema).

• set_title: Sets the piece's TITLE (the name it is saved and published under); once committed, the choice is sealed and nothing overwrites it. Deterministic, $0. Args: title (the new title of the piece: one line, in the piece's language, at most 140 characters).

• set_visual: Set a scene's visual type and/or visual prompt. Deterministic, $0. Args: scene_index, visual_type?, visual_prompt?.

• swap_voice: Change the voice (semantic attributes) of one scene or all of them. Deterministic, $0. Args: voice_spec={...} (semantic attributes only: timbre, cadence, accent, language, apparent_gender, voice_style — NOT a voice id: the concrete voice is a piece-level decision made when the piece is created; a scene has no voice pin of its own, for the human either), scene_index?.

• tighten_hook: Strengthen the opening hook (scene 0). LLM. Args: brief? (scene 0). Requires the write scope. The deterministic ops are $0. Spends LLM budget only on the authoring ops (charged like a chat turn); the deterministic ops are $0.
