| name | higgsfield-scene-engine |
| description | Tests whether a scene is structurally worth generating before any shot is prompted — a five-element engine of Goal, Obstacle, Tactic, Reversal, and Value Shift. Use when the user has a scene, sequence, beat outline, or script and wants it audited or strengthened; when a sequence generates cleanly but lands flat and nobody can say why; when shots look good individually but the run of them does not build; or when the user asks 'is this scene working', 'what's weak here', or 'why doesn't this land'. Upstream of prompting — it decides WHICH shots deserve the credits, not how to write them. Pairs with higgsfield-character-design (who the characters are) and higgsfield-shotlist-director (turning the settled scene into shots). |

Higgsfield Scene Engine — is this scene worth generating?
[DEMO — Tigran (tig-scene-engine), 2026-06-26] [UNPROVEN HERE] These definitions are
bespoke and deliberately not the textbook ones. Apply them as written; do not substitute
standard screenwriting glosses, which are looser and will pass scenes this engine fails.
Why a prompter carries this. Every shot costs credits and iterations. A structurally
dead scene generates just as cleanly as a live one — the model has no opinion about whether
a beat earns its place — so the failure surfaces only after the footage exists and the cut
does not build. This skill is the cheapest pass in the repo: it runs on text, before any
generation, and its whole job is to stop you paying to render a scene that cannot work.
It decides which shots deserve the spend. higgsfield-shotlist-director turns the
settled scene into shots; higgsfield-acting writes the performance inside them.
The five-element engine
1. Goal
The single, unchanging thing the hero is fighting for: to fix what has already been
established and reach, as fast as possible, the result that resolves it. "Already
established" means anything set up earlier — deep backstory, a few scenes ago, or one
minute ago.
- The major goal never changes, and the hero is never wrong about it. He can be wrong
about tactics, never about the goal.
- Every scene goal must be a causal link toward the story goal. Test: if you can
remove the scene and the chain still holds, the scene fails. No orphan scenes.
- "What he ought to do" is not a separate thing to test — the right move is dictated by
Obstacle + Stakes. A hero taking a tactic the stakes would not justify (showering
while the building burns) is a flaggable inconsistency: name it as bad writing or as
deliberate self-sabotage.
2. Obstacle
A strong circumstance that jeopardizes either one stage of the path or the whole goal.
It threatens; it does not merely cost.
- It can be a branching search space (many places to look, limited time) or a single
hard wall (a dead battery — you cannot search a dead machine). A wall typically spawns
a fresh sub-goal with its own terrain.
- Name its scale: local (threatens the current stage) or global (threatens the whole
goal).
- The obstacle is what forces the hero to choose or change a tactic. No jeopardy → no
tactic needed → no scene.
- Audit test: name what is at risk, and at what scale. If nothing genuinely is, the
obstacle is fake and the scene goes slack.
3. Tactic
The move the threat forces the hero to choose — a reasonable guess on his current,
often incomplete, knowledge. This is search under uncertainty, not error-as-stupidity.
- A "wrong" tactic is not dumbness; it is a plausible probe of a space he cannot fully see.
The engine is a knowledge gap: the distance between what he believes and what is.
- Each failed tactic must return information that narrows the search and reshapes the
next move. The drama is the narrowing, not the punishment.
- ✅ good: the tactic is a reasonable bet on current info, and its failure teaches
something new.
- ❌ weak: a tactic he had no reason to try, or a failure that returns zero information —
a wheel-spin. A failing tactic is only a weakness when the failure teaches nothing.
4. Reversal
A turn against expectation. Three forms:
- My own action flips on me — what I did for something starts working against it
(I shower to make the pitch; the shower makes me late and I miss it).
- Hidden agency revealed — the thing or person I thought I was acting on was acting
on me all along. The thriller move; it often fires exactly when the knowledge gap closes.
- The general case: the situation turns opposite to what the tactic intended.
Placement: at least one reversal per sequence. A single scene may be pure
escalation, but a resolved sequence with zero reversals fails.
A sequence is the run of scenes from when a specific jeopardy opens to when it resolves —
overcome, or it defeats him and forces a new path. Sequences nest, and each resolving
unit needs its own reversal. Flag which scale you are auditing.
5. Value Shift
The change in the AUDIENCE'S read of a character, triggered by a reversal. The keystone,
and the most misunderstood element: it does not happen on the page, it happens in the
viewer's mind. Each reversal forces the audience to re-judge the character — a moving
verdict they keep revising (nice → experienced → cunning → no, he's desperate → devoted son
→ what a man).
THE CORE RULE: a reversal with no value shift is inert. A structural turn is not a
reversal unless it moves the audience's verdict. If you cannot name a before-verdict
and an after-verdict the audience would hold, the turn is dead weight no matter how
much plot flipped.
Audit the trajectory, not just presence: are the revaluations building a deepening
portrait, or just oscillating?
The causal chain
Goal (fixed; every scene a causal link toward it)
→ Obstacle (jeopardizes a stage or the whole goal; name what is at risk + scale)
→ Tactic (forced by the threat; a reasonable guess; its outcome must return information)
→ Reversal (turn against expectation; ≥1 per resolved sequence)
→ Value Shift (the audience re-judges the character; no shift → the reversal is useless)
Audit procedure
Work the chain in order. Reversal and Value Shift are judged at the sequence level, not
the scene.
- Goal — state the scene goal in one line. Is it a causal link to the story goal? Apply
the removal test. If you do not know the story goal, ask — you cannot fully audit Goal
without it.
- Obstacle — name the circumstance, exactly what it jeopardizes, and the scale.
- Tactic — is each forced by the jeopardy, reasonable on current knowledge, and does
each outcome return information? Flag wheel-spins and unmotivated tactics.
- Reversal — locate them, name the form, confirm ≥1 per resolved sequence.
- Value Shift — for each reversal, name before-verdict → after-verdict. If you
cannot, mark it INERT and make it the priority fix. Then assess the trajectory.
Audit output
SCENE/SEQUENCE: <one-line identification>
CHAIN CHECK
• Goal — <verdict + one line>
• Obstacle — <what's jeopardized + scale + verdict>
• Tactic — <forced? reasonable? returns info? verdict>
• Reversal — <form + present? ≥1 in sequence? verdict>
• Value Shift — <before-verdict → after-verdict per reversal, or INERT; trajectory note>
WEAKEST POINT: <the single element that, if fixed, recovers the most>
WHAT IF…
1. (Minimal) <change ONLY the weakest point so the rest of their scene still works>
2. (Clean) <a version that fully works, even if it departs further from the original>
3. (Optional) <only if it genuinely adds something>
The three tiers matter in that order: minimal preserves the user's version, clean is
yours, and the third is optional. Do not collapse them into one rewrite.
Where this sits before prompting
Once the chain holds, the scene is worth spending on — and only then:

The most common real failure to hunt for first: a reversal that turns the plot but does
not move the audience's verdict. Surface it before anything else — it is the one that
survives a read-through, generates beautifully, and still lands flat in the cut.
