A base64 string of 128+ characters appears in a documentation file. Encoded prompt injection hides the hostile instruction in base64 — invisible to keyword filters — and relies on the agent's ability to decode it at runtime. There is no normal authoring reason to embed a multi-hundred-byte base64 blob in skill docs.

Generate a cinematic "freeze effect" video where time stops mid-scene, the subject walks through the frozen world, then time resumes with a snap.
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
photo | image_url | yes | — | Reference photo of the main character (face/body) whose appearance must remain consistent across all shots. |
scene | text | no | a packed, dimly lit sports bar with neon accents, blurred TVs showing a championship celebration | The setting where time will freeze (e.g. "a busy nightclub", "a wedding reception", "a stadium crowd"). |
freeze_moment | text | no | golden arcs of beer suspended midair, popcorn floating motionless, people frozen mid-cheer | The signature frozen visual — what hangs in the air when time stops. |
closing_line | text | no | perfect | A short word/phrase the character whispers before resuming time. |
aspect_ratio | text | no | 16:9 | Output aspect ratio — "16:9" for cinematic, "9:16" for vertical/social. |
duration | text | no | 15 | Target duration in seconds (10 or 15 recommended). |

Steadicam frontal medium shot tracking the person walking confidently through the crowd.
The crowd erupts in euphoria around them.
As the person walks, they raise their right hand and snap.

At the snap, a subtle spherical shockwave bursts from their fingertips — air distortion and light refraction ripple outward.
Everything freezes mid-motion.
{{freeze_moment}}.
Neon light catches dust and liquid in the air.
Absolute silence.
[0:06–0:09]
Only the person moves.
Soft, echoing footsteps.
Camera tracks backward as they walk through the frozen scene, observing calmly.
They reach out and pluck a single suspended detail from the air.
[0:09–0:11]
They stop in front of a frozen onlooker, face locked in an ecstatic expression.
The person tilts their head, gently observes.
Softly: "{{closing_line}}".
[0:11–0:15]
They turn, face the camera, smirk, and snap again.
A stronger reverse shockwave ripples outward.
Motion instantly resumes — sounds explode back, people land mid-jump.
The person walks away as the camera pushes through the celebrating crowd.
Fade to black.
