Before After Ad
Purpose
Create approval ready before and after ad concepts and shot scripts. Make the
starting state inspectable, show a plausible product use behavior, and resolve
with controlled visual evidence rather than an unsupported transformation claim.
Produce a Before After Grammar Plan , shot script, one approval checkpoint, and
direct downstream handoff after approval.
Workflow
1. Ground The Brief
Read the smallest useful source context first:
product facts, approved claims, usage instructions, and substantiation
audience, persona, concern, desired visible result, and duration
product, creator, scene, audio, and style references
prior reference video analysis or benchmark notes when relevant
If the user supplies raw reference videos without an analysis, use
media analysis first. Do not infer style from filenames, thumbnails, or a
single frame.
Lock these before writing:
starting state
desired result state
pressure carrier
product capability
approved proof
claim boundary
persona and concern map
product appearance
duration and format
reference duties
Ask only when a missing fact would change the product, proof, claim, identity,
or workflow. Do not invent treatment timelines, dosage, medical causality,
guaranteed outcomes, or product appearance.
2. Design The Proof Grammar
Read references/style grammar.md .
Produce a Before After Grammar Plan with these fields:
core human state
pressure carrier
baseline evidence
comparison control
product entrance
product gesture
result evidence
camera language
framing rules
movement rules
edit rhythm
sound mode
text mode
claim boundary
continuity locks
generator risks
Choose one primary proof route:
direct comparison : baseline → use → matched result → optional split view
discovery : external trigger → inspection → use → result
routine montage : concern → repeated normal use → result portrait
Do not copy a reference creator, exact scene, wording, music, brand marks, or
recognizable personal details. Transfer only reusable camera, movement, edit,
proof, sound, and text behavior.
3. Write The Shot Script
Read references/shot script rubric.md .
Return a shot table with exactly these columns:
time visual framing/composition camera motion action sound subtitle/text proof duty purpose
After the table, return Production Locks with:
persona lock
concern map lock
product lock
scene lock
before after match lock
audio lock
claim lock
post only elements
Keep each shot physically executable. Use one clear action per shot. Treat
captions, arrows, circles, split screen assembly, end cards, disclaimers, and
comparison labels as post production elements rather than generated scene
content.
After the script, ask whether the direction is approved. Stop before media
generation unless the user approves or explicitly asks to
continue into production in the same request.
4. Handoff After Approval
Read references/downstream handoff.md and hand off directly:
Use image batch runner first when persona, product lifestyle, concern map,
matched before/after, first frame, or per clip scene images are needed.
Use video batch runner when the approved script and required hosted assets
already exist and the user wants renders.
Pass the approved plan, script, locks, facts, claim boundary, source basis, and reference duties without a redundant brief or second confirmation.
Let the downstream skill own model selection, request schema, upload rules,
render execution, polling, and manifests.
Quality Bar
Make the problem inspectable before a normal product use gesture.
Match proof critical before and after framing, posture, light, and concern area.
Put the emotional shift after evidence and preserve natural texture.
Use one restrained text system, hard cuts, and subject driven motion.
Separate observed state, testimony, and substantiated product facts.
Stop Conditions
Stop when required product appearance lacks an approved reference or creation permission.
Stop when the requested result or timeline exceeds the approved claim boundary.
Stop when comparison cannot be honest or references contain no transferable grammar.
Keep grammar plans, rubrics and continuity checks as working context. Present the requested script or assets and decisions that affect the result; do not require a separate handoff file or repeated approval when the same agent can continue within existing authorization.
