Deliver a playable final video, cover, subtitles, voiceover script, and inspection record. Default to Simplified Chinese, 1920×1080, and 30fps; the user's language, dimensions, art style, voice, and reuse requirements take priority. Duration follows the content and actual voiceover; page count, layout, and seconds per page are not fixed.

First read Dependency Routing, then read the built-in guides as needed. They are production resources for this skill, are not installed separately, and do not take over the task on their own. The main content is designed through model reasoning, while the script only executes assets and a timeline that have already been determined.

First check whether a topic, story, body text, attachment, or explicit source is already available. Pause and request a topic or story only when all of these are missing. All other production preferences are optional and do not constitute blockers that require another approval.

Production builds and renders must reject invalid input when the complete narration and corresponding timestamps have not been locked, the default or selected art style has not been resolved, the pre-generation check is missing, body parts do not match, an entire person has been treated as a single part, outlines are missing, disconnected lines have been joined across blank space, or inspection records are outdated. The model must repair these issues and then continue; unselected preferences must not trigger this gate. Scripts may only verify structure, hashes, pixels, and paths. They cannot replace the model's visual review of the head and neck, occlusion, stroke intent, or art style quality.

Before every call to an image-generation or image-editing tool in this project, the model must fully read and apply . This is the user's explicit authorization for the project and is not blocked by the guide's rule when the guide is used independently. The requirement applies to the cover, body content, characters, props, new hands, candidate images, variants, local edits, and rework. It must not be skipped on the grounds that the change is merely an attempt, a reused style, or a small adjustment.

Before generating an image, write the brief for that image and the complete prompt actually used in the current run, and save them in the task directory. Register and in the art record, run to bind the content hashes, and only then call the image tool. Generating an image first and writing the guidance record afterward is prohibited. If the prompt or brief changes, redo the art direction, bind the evidence, and generate the image again. The same output image must not borrow an updated record to impersonate a new generation.

After generation, actually inspect the image and record the guidance version, sanitized image hash, visual conclusion, and evidence. If a record is missing, the brief or prompt is empty, a hash does not match, the visual inspection fails, or the image has been replaced, stop construction, rendering, and delivery. only binds existing text; it does not fill in or prove image quality. Previously accepted assets may retain their original records when reused byte-for-byte. Any edit requires new evidence for the current run.

Only one subtitle may be displayed at any given moment for the same narration. Two subtitle systems must never be overlaid, whether they come from text baked into the image, subtitle events, an embedded MP4 subtitle track, a web , or a subtitle file automatically loaded by the player. The default is white text with a thin black outline and no backing panel. The uniqueness requirement still applies when the user selects another treatment.

Recomposite only from subtitle-free assets and an independent subtitle layer. Never overlay a second subtitle layer on a completed video that already contains hard-coded subtitles. During construction and rendering, verify that cues and subtitle events correspond one-to-one, have consistent roles, and do not overlap in time. For delivery, verify that the MP4 contains no additional subtitle tracks and that its directory contains no SRT, ASS, VTT, or other subtitle files. Place editing subtitles only in , and do not add subtitle tracks to the preview page. Finally, inspect long sentences, line changes, and the ending in the actually decoded frames. Any duplicate subtitle is a direct FAIL and must be corrected before delivery. Automatically enabled translation or live captions in third-party players must be disabled separately. Do not treat a display source that could not be reproduced as an identified cause.

The six arm styles are , a deep-blue-sleeved marker; , fair skin with delicate crushed-diamond long nails; , children's colored pencil; , a calligraphy brush inspired by Shangguan Wan'er; , a neutral pen with a white shirt cuff; and , a fountain pen with a knit sleeve. There is also , which uses only a drawing implement with no arm. The model chooses the default according to the content, and the anchors are located in . Calibrate the arm's scale from the pen tip to the wrist and keep the cropped edge outside the frame. For , calibrate against the complete pen body and do not apply the forearm rule.

adds advertising only to the pen barrel, supports at most 16 characters, and is empty by default. Preserve the user-provided text and inspect contrast and readability at normal size. If the text is too long or difficult to read, prioritize enlarging the available barrel layout or simplifying the design; do not arbitrarily change the advertising name. Custom skin, manicures, writing instruments, and sleeves must pass through the same art direction, privacy, and anchor checks. Crushed diamonds must not be replaced with large gemstones, and clear skin must not be traded for blurriness.

uses the user's original text, may contain line breaks, and is empty by default. Generate a low-opacity, slowly floating text watermark that remains within the frame and avoids the subtitles. See Optional Production Settings for its parameters and checks.

provides . Read the runtime contract before invoking it. Store task data in an independent directory rather than the installation directory. distinguishes the conditions for a new narration-generation service from offline compositing with existing audio. When required resources or capabilities are missing, report the specific blocker.

Quality comes first. Engineering gates verify execution order and completeness, but the model must still review semantic partitioning and design. Chinese characters are approximated through glyph outlines, and calligraphy stroke order is not guaranteed. Real handwriting naturalness, emotional impact, and learning effectiveness must be evaluated separately. Do not promise that every topic can be generated reliably in one pass. Do not publish additional videos, activate services, or change global model configuration.

Public hands, voice presets, and preview images use Hosted Assets. Download and verify them on first use, then reuse the cache. Original-footage recordings and the user's personal voice library remain local and must not enter public hosting.
