What it does
Video Poster Design is an agent skill from MagicCube/agentara. Create cinematic movie poster concepts and final poster images from a user's brief, existing video plan, storyboard, character design, or project context. Use this skill whenever the user asks to generate a film poster, movie poster, key art, campaign poster, teaser poster, title poster, or promotional visual for a video project. This skill proposes several creative directions first when appropriate, defaults to a 3:4 poster ratio when no ratio is specified, and ensures typography, title treatment, imagery…
Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Comics and storyboards, Generative and creative coding and Typography. The repository describes itself as: Your 24/7 personal assistant powered by Claude Code and OpenAI Codex. Multi-channel messaging, long-term memory, skills, task scheduling, session management, and more — all…
When your agent uses it
- The user asks to generate a film poster
- Campaign poster
- Promotional visual for a video project
Example prompts
- “/video-poster-design”
Workflow steps
10 steps, taken from the first numbered list in SKILL.md.
- Read relevant project context: plan, storyboard, character design, prior poster references, or user brief.
- Extract title, ratio, story, genre, main subject, visual references, and required text.
- If ratio is missing, set it to 3:4.
- If the creative direction is not already clear, propose 3-5 concepts and ask the user to choose.
- After the user chooses, write a compact poster spec if helpful.
- Generate the poster image using the selected concept and all relevant references.
- Save the image to posters/{poster-name}.png.
- Inspect the result if possible: ratio, composition, typography, character consistency, artifacts.
- If text rendering is poor and exact text matters, recommend or perform a second pass with deterministic text overlay when appropriate.
- Final response should include the saved path and render the image when supported.
What it can do on your machine
Read from SKILL.md and the folder at commit 5621a96. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Video Poster Design loads about 2.5k tokens when it runs. Until then it costs about 150 tokens; SKILL.md has 906 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 906 words (~2,476 tokens).
“Use this skill to create movie-poster-style key art for a video, short film, vlog, TVC, storyboard, or campaign.”
