name: higgsfield-seedance
description: "Rewrites scene descriptions using professional cinematography language, structures prompts with a six-slot formula (camera + subject + action + setting + style + lighting), and diagnoses content filter rejections via a preflight linter. Use whenever the user asks for a Seedance 2.0 / Seedance Pro prompt, describes a scene for Seedance generation, mentions Seedance, reports a Seedance generation failure or flagged prompt, or is burning credits on Seedance regenerations."

QUICK FACTS

*Generated-checked block (scripts/build_index.py verifies anchors). Read the linked sections for full context — these lines are routing aids, not the rules themselves.*

• The filter is an LLM reading full-scene intent, not a keyword blacklist — describe a SCENE, not a subject; fix the voice first [→](#the-filter-model-read-this-first)
• Instant fail (<10s) = filter rejection; delayed fail (>30s) = infra/complexity — never regenerate an instant fail unchanged [→](#instant-fail-vs-delayed-fail-the-diagnostic)
• Six slots, in order: Camera + Subject + Action + Setting + Style + Lighting; missing 3+ slots is where flags come from [→](#the-seedance-prompt-formula)
• Empirical prompt-craft laws: 50–80-word attention sweet spot (front-load the load-bearing element), name a director/lens not "cinematic", "fast" degrades motion, no negative prompts in the body, unidirectional motion chains + named camera endpoint + detail scale follows shot size [→](#prompt-craft-laws)
• Five prompt modes: Reference-Based / Continuation / Expand Shot / Edit Shot / Transformation — pick the mode before writing [→](#seedance-20-prompt-modes)
• [OFFICIAL] block scaffold for production prompts: SCENE CONTEXT → … → POSITIVE LOCKS, distributed style on standalone briefs (connected shotlists glue the compiled Style Prefix verbatim instead), FOV in degrees only, CAMERA block 3rd, cut ladder oner / CUT n / timed / freestyle [→](#official-prompt-architecture-the-block-scaffold)
• [FIELD] 13-project corpus calibration: word length scales with register (218w → 2,059w medians — the 50–80w sweet spot is single-shot-only), video briefs hand-authored (`enhance_prompt` off), Style Prefix = per-project constant compiled into home blocks [→](#field-calibration-the-13-project-production-corpus)
• [FIELD] Three "helpful-instinct" drift sources, each with a standing lock: environment invention (#1, above character drift), character-height equalization, scale drift on wides [→](#positive-locks)
• Build-safe construction for crowds/destruction/creatures: evacuated cities, contained fights ("stays at the sea surface"), the safe benchmark scene [→](#build-safe-construction-crowds-destruction-creatures)
• Extend an existing clip: attach it as a video reference + open with "The scene continues." — match source resolution AND duration; chain cap ~2 (hard 3), then re-anchor from ORIGINAL references [→](#extension-prompting-video-reference-continuation)
• **This file is Seedance 2.0.** For **2.5** — four modes incl. `video_edit` / `video_extension`, 4–30s, 30/10/10 references, in-prompt first-last frames, 720p ceiling — use `../higgsfield-seedance-2-5/SKILL.md`
• Tutorial-demonstrated patterns (reference-role vocabulary incl. VARIETY reference, SCREEN REALISM + duration-match composites, 60:30:10 grade, red-arrow prop annotation): `PRODUCTION-PATTERNS.md` in this directory
• [OFFICIAL] Feature-film pipeline (asset construction, per-scene GEO SPATIAL LAYOUT, the position-fixing first second, dialogue construction, ban dictionary, the 10–15 iteration rule, crowds / giants / thresholds): `HELL-GRIND.md` in this directory
• Performance — objective, obstacle, tactics, beats, subtext, eye life, the acting master profile: `../higgsfield-acting/SKILL.md`
• Hard engine rules (age-blind, exit-frame = cut, off-screen = nonexistent, no reflections, ≤3 tracked characters, double-contrast cuts) + high-risk shot table: `ENGINE-RULES.md` in this directory
• Reference roles: Character / Last-Frame / Environment / Prop — role determines what the prompt may re-describe [→](#reference-roles)
• Working modes: Exploration / Continuation / Bridging / Repair (distinct from prompt modes) [→](#working-modes-vs-prompt-modes-two-taxonomies)
• Layer 1 briefing vs Layer 2 production prompt — never paste Layer 1 into the prompt box [→](#two-layer-prompt-authoring)
• Native **4K** is available in `mode=std` only; `mode=fast` (Seedance 2.0 Fast) caps at 480p/720p — in Cinema Studio the model is still capped at 1080p [→](#pre-flight-linter)
• Always preflight: `python3 scripts/seedance_lint.py --preflight --model seedance_2_0 "<prompt>"` — enums come from `../../specs/model-specs.json` (fast+1080p/4K and Kling 21:9 are auto-caught) [→](#pre-flight-linter)
• 480p drafts validate the prompt, NOT the take — no seed param; pin Hero Frame + start/end frames to carry a look [→](#drafts-validate-the-prompt-not-the-take)
• ZH prompts: hard 1,800-char cap; ZH antislop list enforced by the linter [→](#multi-language-prompt-workarounds)
• Flagged prompt → rewrite playbook per linter rule, then voice pass [→](#the-rewrite-playbook)
• Repeated flags → full loop-breaker procedure + LOG THE OUTCOME (`--confirmed` / `add-quality`) [→](#when-the-user-is-already-in-a-failure-loop)

Use this skill whenever the user wants a Seedance 2.0 / Seedance Pro prompt, OR whenever a Seedance generation has been blocked, flagged, or silently failed. This skill's job is to stop credit waste on filter rejections.
