Poster Design Studio

Create one scroll-stopping poster, flyer, or promotional banner from a topic
description, a product or scene photo, or an accepted draft. Reuse decisions
already present in the conversation and move by the shortest route that
completes the requested poster.

Choose the route

• Generate a poster from a topic: when the user describes an event, sale,

movie, music night, product launch, or social campaign and no source photo is
required, turn the brief into a complete poster visual using
beatra.images.generate. This is the default when the request is topic-led.

• Transform a photo into a poster: with a product, scene, or brand photo,

elevate it into a polished poster or banner with strong hierarchy, category
styling, and a text-safe zone using beatra.images.transform. This is the
default when a source photo exists.

• Refine an accepted draft: use beatra.images.edit with the accepted

poster as images[0] to fix color, composition, text area, or background
without changing the overall layout.

Follow poster routing for the precise branch and
poster craft when turning the request into a
visual specification that fits the poster type and category.

Shape one poster brief

Reuse the user's campaign topic, poster type, target audience, style
preference, and any visual references. Ask only when a missing decision
materially changes the result. For a standard poster, propose the canvas that
matches the destination—A-series print, social media ratio, or standard poster
proportion—with a clean text-safe zone for the headline.

Build the brief around:

• the poster type and category—event poster, promotional banner, music or

concert poster, movie poster, product launch, sale or flyer, or social media
graphic;

• the headline message—the event name, film title, sale offer, or campaign line

that anchors the composition;

• one focal subject—the performer, product, hero scene, or key visual that

anchors the poster;

• one style direction—clean and futuristic (tech), warm and appetizing (food),

editorial and bold (fashion), vibrant and energetic (music), professional and
clean (corporate), or friendly and approachable (education);

• the canvas and destination—A3 or A4 print, 1:1 square, 9:16 story, 16:9

banner, or 2:3 / 3:4 standard poster;

• a text-safe zone preference—top band, center, or lower third—so the user can

place the headline and details later without clashing with the image;

• ordered visual references when available (brand color reference, style

inspiration, composition reference).

If the user has already stated the topic or style, reuse it. If that choice is
genuinely missing, propose the best default and include it in the single
paid-call confirmation.

Prepare the call

Use only this Skill's bundled scripts/mcp_client.py for every remote MCP
operation. The tool name is a CLI argument and the tool arguments are the JSON
sent on stdin. Do not configure or call a host Beatra Connector, and do not use
REST/OpenAPI as a fallback. For exact commands and troubleshooting, use
Bundled MCP Client diagnostics.

• For a topic-led concept, call beatra.images.generate with the canvas that

matches the destination and a prompt that captures the desired mood, color
palette, hierarchy, and text-safe zone.

• Upload the source photo through the bundled client helpers first, then call

beatra.images.transform with the uploaded artifact as the first ordered
reference. Label the photo's role explicitly in the prompt so the model
preserves the subject.

• For an accepted draft, call beatra.images.edit. Use at most two normalized

edit_regions on image_index=0 for localized fixes; omit regions for a
whole-image adjustment.

Uploading makes bytes available to the remote tool; it does not itself inspect
the image. Review only visual facts the host can actually see.

Keep model=auto and count=1 unless the user explicitly chooses otherwise.
Call beatra.models.list only for a real model, availability, compatibility,
or price decision. The detailed request shapes and examples are in
workflow.

Confirm and execute once

Planning and brief preparation are free. Before the paid image call, show and
freeze the final prompt, ordered references, canvas, poster type, style
direction, text-safe zone, model, controls, and output count. Merge any
still-material high-impact choice into this one confirmation.

After approval, create one stable opaque client_request_id for that exact
logical request and submit it once. A changed prompt, reference or order,
canvas, poster type, style direction, model, count, or control is new paid work
and needs a new confirmation and a new ID.

Track, review, and deliver

After receiving a task_id, poll only that task with beatra.tasks.get. If the
ID is lost, use beatra.tasks.list to find candidates and verify the selected
one with tasks.get. Only when the original response status is genuinely
unknown may the exact same parameters and same client_request_id be used for
idempotent recovery. Slow polling, an update failure, an authorization failure,
or a connection failure never creates a replacement paid task.

Use beatra.tasks.cancel only when the user asks. If cancellation returns
409, continue tracking the original task. See [review and
recovery](references/review-and-recovery.md) for the full recovery contract.

When the result is visible, review visual impact (does the poster stop the
scroll and read clearly at a glance?), text readability (is there a clean
text-safe zone for the headline and details?), brand consistency (do colors and
mood match the category and brand direction?), canvas fit (is the ratio correct
for print or social?), and overall craft. Deliver the artifact links, observed
dimensions, task ID, and billing.net_charged_credits. Offer at most one
focused, unexecuted revision. Generated assets can also be viewed and managed at
beatra.ai.

If the tool returns insufficient credits: give the user the tool message in
full. Do not change the URL. You may translate the other words. Do not replace
it with your own top-up copy. Point the user to pay using that message.

When the user asks how many credits remain, 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.

Installation, updates, and account operations

For first use and shared operations, follow [installation and
authentication](references/installation-and-auth.md), [installation
registration](references/installation-registration.md), [tasks and
results](references/tasks-and-results.md), [billing, errors, and
recovery](references/billing-errors-and-recovery.md), and [uninstall and
disconnect](references/uninstall-and-disconnect.md).

This Skill performs a silent check at most once per 24 hours while a public
command runs. When a newer package exists, it installs automatically without
separate confirmation. Updates come only from the fixed official Beatra
discovery address and immutable Beatra CDN path for the embedded identity.
Before replacement, the client verifies the discovery document, manifest,
archive, and every packaged file using identity, size, and SHA-256 checks. It
replaces only package-owned files in this installed Skill directory. If any
check, download, replacement, or rollback fails, the current installation stays
usable and the original command continues. Canonical English installs stay on
canonical/en, and SkillHub Chinese installs stay on skillhub/zh-CN.

The user can persistently control automatic updates:

python3 scripts/mcp_client.py update --auto off
python3 scripts/mcp_client.py update --auto on
python3 scripts/mcp_client.py update --check

behavior, and control details.
