About this skill

Problem

When producing brand festival posters, engineers or operations teams often repeat prompt setup, copywriting, brand details, and manual resizing for platforms like WeChat Moments or Xiaohongshu. Maintaining templates across many holidays and solar terms is labor-intensive.

How It Works

festival-poster organizes generation around 38 Chinese traditional holidays and solar terms, calls the Doubao SeedImage model, and outputs 1080×1920px / 9:16 vertical posters. Key capabilities include:

  • Festival coverage: 15 traditional holidays plus 24 solar terms, suitable for scheduled poster generation.
  • Brand memory: initial configuration is stored in ~/.festival-poster/brand.json, so brand details are not re-entered every time.
  • Local API configuration: the API key is saved in ~/.festival-poster/config.json for routine use.
  • Configuration override: existing values can be replaced by running --brand or --api-key again.

In practice, prepare a Doubao API key, complete the one-time setup, then generate posters by holiday or solar term.

Boundaries

  • Focused on Chinese holidays and solar terms, not a full brand design system.
  • Depends on the external Doubao SeedImage API, subject to key validity and account balance.
  • Output is best for vertical social media assets; complex layouts may still require manual refinement.

Use Cases

  • A social media operator prepares pre-holiday Moments posts and needs branded 1080×1920 festival posters quickly.
  • A brand teammate publishes solar-term content and needs vertical solar-term posters while reusing saved brand details.
  • A marketing lead changes the brand name and needs to override the setting with `--brand` before regenerating posters.
  • A developer calls Doubao SeedImage in local scripts and wants the API key and brand settings saved in the user directory.

Best For

  • Social media operations owners who need vertical promotional posters for traditional holidays and solar terms.
  • Brand design collaborators who want to reuse a fixed brand name and avoid repeating poster setup.
  • Marketing campaign leads who need to override brand or API key settings and regenerate posters quickly.
  • Local automation developers who want to call Doubao SeedImage poster generation from scripts using local config files.
