Assembly One-Step Clips

Turn authorized stills and seller-supplied step facts into one assembly step video per still. This one-step clip studio turns each still into a product assembly clip. Use it for furniture assembly video and how-to step clip work that stays one photo one clip.

Turn authorized assembly stills and seller-supplied step facts into one short clip per step. Deliver the clips in step order. Do not stitch them.

Scope and adjacent routes

Use this Skill when a seller or listing team wants one short motion clip for each assembly step they already photographed.

Route a talking product demo from one photo plus a script to product-video-studio. Route listing room stills to listing-room-video-pack. Route a generic still that is not an assembly step to image-to-motion. Do not look up public posts for missing steps.

Inputs and defaults

The hard inputs are:

• at least one accessible still the host Agent can inspect, in step order;
• seller-supplied step facts that name what each still shows (part, action, or sequence number).

Do not invent a missing step, torque spec, tool list, or warning. A still is not a source for unstated instructions. Reuse SKU name, language, destination, and must-keeps already in the conversation. Ask only for a missing hard input.

Default to one beatra.videos.animate call per still, model: "auto", the still as the strict first frame, no driving_audio, and a source-derived aspect ratio. Choose a supported integer duration in the 2–15s range with the user; if they do not pick, use 5s.

Golden path

1. Inspect every still. Record MIME type, width, height, aspect ratio, byte size, and whether it has an alpha channel. For a local file, upload only through the bundled client after inspection. Never pass a local path to a remote tool.

2. Write a labeled one-step plan from the seller's facts and what the stills actually show. Keep step order. Leave a still whose fact is missing on the plan. That plan is the free visible result. Planning is not approval.

3. Call beatra.models.list with {"capability":"image_to_video"}. Admit each still against a current card that accepts a first-frame image without driving audio. Compare every image fact and the chosen duration with advertised constraints. If any required media fact is unavailable or incompatible, stop before video.

4. Show one current production card and wait before any video client_request_id or beatra.videos.animate call:

   1. Work — one assembly-step clip per named still, a generate call (beatra.videos.animate).
   2. Credits — the live image_to_video price just read. Do not reuse a remembered number.
   3. Count — one paid call per still. Do not batch steps into one submit.
   4. Identity — one new opaque client_request_id per still. A changed prompt, still, duration, model, or control mints a new ID.
   5. If we stop here — the labeled step plan remains usable.
   6. If the balance is insufficient — relay the official message and its top-up URL exactly. Translate the prose; keep the URL. Do not retry until the seller says they have topped up.

   Do not submit until the user confirms they have topped up or already have enough credits.

5. Submit beatra.videos.animate exactly once per admitted still through bundled scripts/mcp_client.py. Do not configure a host Beatra Connector. Do not use REST/OpenAPI as a fallback. Poll each video task with beatra.tasks.get until terminal.

6. Deliver the clips in step order with actual dimensions, duration, usage, and billing.net_charged_credits. Review step identity, motion, and must-keep drift. Never invent a stitch, concat, or editor tool.

Decisions that require confirmation

Planning and live price quotes are free. They are not approval. Video animate needs the six-field card above. File access is not consent to reuse a still outside this step set.

Recovery

Each paid still has its own frozen payload and ID. Recover a lost create response only with that still's identical payload. Recover a lost task ID through beatra.tasks.list and beatra.tasks.get. Call beatra.tasks.cancel only when the user asks to cancel that still; on 409 keep polling. On insufficient_balance, keep the top-up URL inside the balance error exact and retry the same frozen ID only after the user says they have topped up. If a create returns no task_id, do not poll; reconcile before minting a new ID. A changed still, prompt, duration, or model is new work and a new card.

Execution

Invoke every remote Beatra operation only through this package's bundled scripts/mcp_client.py. Put the MCP tool name after call and send one JSON object on standard input.

bash

python3 scripts/mcp_client.py call beatra.models.list

json

{"capability": "image_to_video"}

Do not configure or call a host Beatra Connector, and do not use REST/OpenAPI as a fallback.

Account balance

When the user asks how many credits remain or whether a live estimate fits, call beatra.wallet.get. When they ask what was charged, call beatra.wallet.ledger. Both are read-only. Do not invent an account-balance or top-up tool. Do not make wallet.get a required step before every paid submit.

When a model card comes back carrying a top_up block, relay its tiers as the card lists them and in that order. Do not rank them, do not talk one down, and do not pick one for the user. Which tier suits them is their call, made on the wallet page with the whole list in front of them. Never quote a tier from memory.

References by task

• For step plans, payloads, confirmation, polling, recovery, and review, read Assembly one-step workflow.
• For authorization and the non-billable registration step, read installation and authentication and installation registration.
• For shared task, billing, and connection details, read tasks and results, billing, errors, and recovery, and Bundled MCP Client diagnostics.
• For update guarantees and controls, read automatic updates and safety. For removal, read uninstall and disconnect.

Runtime and safe automatic updates

The bundled client silently checks for a newer release at most once every 24 hours per installation. When a newer version is available, it installs automatically without separate confirmation. It downloads only from the fixed official Beatra discovery and immutable CDN paths for this package, channel, and locale, verifies discovery data, archive, manifest, and every packaged file, and replaces only package-owned files.

Update checks, downloads, verification, replacement, rollback, and recovery fail open: the current installation remains usable and the original command continues. An update failure never authorizes retrying a paid video request. The setting persists for this installation. See automatic updates and safety.
