What it does

Flux 3 Cinematic Inserts is an agent skill from black-forest-labs/skills. Use when writing a FLUX 3 text-to-video prompt for a standalone shot. Covers shot craft, reliable concept patterns, camera, continuity, and review.

Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `metadata.json`, `references/field-guide.md` and `references/review-scorecard.md`).

It sits in Media & Creative, covering AI video generation. The repository describes itself as: Official agent skills from Black Forest Labs for FLUX image and video generation — prompting guides and API integration patterns for Claude Code, Codex, and any… The licence is MIT.

When your agent uses it

  • Writing a FLUX 3 text-to-video prompt for a standalone shot
  • Tasks that involve AI video generation

Example prompts

  • “/flux-3-cinematic-inserts”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Opening frame: composition, subject, setting, light.
  2. Visible cause: source and contact point in the same frame as the response.
  3. Physical response: direction, material behavior, restraint.
  4. Payoff: one final state that works as an edit point or a still.
  5. Continuity contract: same set and geometry; no cuts, transitions, frozen or
  6. Audio intent: name material textures; route critical sync and mixing to post.

What it can do on your machine

Read from SKILL.md and the folder at commit 8907d51. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Flux 3 Cinematic Inserts loads about 700 tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 43 tokens; SKILL.md has 346 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~700
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

FLUX 3 Cinematic Inserts

Build one standalone shot around one motivated physical or atmospheric event: B-roll, a bridge, a material detail, a capability test. Reroute when success requires supplied media (flux-3-keyframes-continuation), exact typography, frame-accurate sync, a multi-step mechanism, close human performance, or finished ad copy; those need conditioning or post, not a text-only generation.

Before writing, settle the contract in one sentence: the visible cause, the physical response, and the payoff. Then pick a proven lane from references/field-guide.md (atmospheric light in a medium, wet reflections, viscous macro, tactile contact and ignition, restrained noir); treat anything it marks experimental or parked as a test, not a promise.

Write the shot in this order:

  1. Opening frame: composition, subject, setting, light.
  2. Visible cause: source and contact point in the same frame as the response.
  3. Physical response: direction, material behavior, restraint.
  4. Payoff: one final state that works as an edit point or a still.
  5. Continuity contract: same set and geometry; no cuts, transitions, frozen or repeated frames, or resets.
  6. Audio intent: name material textures; route critical sync and mixing to post.

Camera is one physical contract: framing, angle, movement, focus. A locked-off camera cannot track; an extreme close-up cannot establish. Locked and deliberate by default; move only when it serves the event.

Style must be visible: "tense" becomes rigid posture, shallow breathing, and a slow push-in; "vintage" becomes a named capture format, grain structure, and practical light. No unmotivated sparks, bells, or effects.

Draft first (draft: true) while the concept is unproven, and judge the draft on event legibility, composition, camera, and continuity; softness is the low-step trade and resolves at full quality. Iterate as a ladder, one consequential change per variant: event geometry, then material or light, then composition, then duration. After two structurally similar misses, change the concept or the production method, not the adjectives. Review the result with references/review-scorecard.md: a technically valid clip still has to be useful, physically legible, deliberate, and interesting.

Hand the finished prompt to flux-3-generate as a text-only request, with the risks and anything post must own.
