# Spring AI Movie Poster Copywriter > Build a movie-poster one-line recommendation pipeline that takes movie title and description, gathers context from Douban and encyclopedia pages, and generates 3-5 Chinese recommendation lines with exactly 12 Chinese characters each. Use when Codex needs to implement crawler-to-prompt workflows, output validation, and recommendation generation APIs. Use when this capability is needed. - Skill: `tomevault-io/spring-ai-movie-poster-copywriter` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/spring-ai-movie-poster-copywriter` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/spring-ai-movie-poster-copywriter/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Design & Media - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/spring-ai-movie-poster-copywriter --- # Spring AI Movie Poster Copywriter ## Workflow 1. Collect request payload: - Require `movieTitle` and `movieDescription`. - Accept optional `year`, `genre`, and `tone`. 2. Retrieve context: - Query Douban and encyclopedia pages using search first, then fetch detail pages. - Extract only concise facts: genre, setting, themes, cast keywords, awards, and plot hooks. - Ignore user-generated long comments and spoiler-heavy content. 3. Normalize context: - Convert raw HTML into a compact context block under 1200 Chinese characters. - Keep only deduplicated facts and keywords. - Store retrieval source URLs for traceability. 4. Generate candidates: - Load prompt templates from `references/prompt-template.md`. - Ask model to generate 8-10 candidates first. - Keep temperature moderate (`0.6` to `0.8`) to balance creativity and control. 5. Validate and filter: - Run `scripts/validate_slogans.py` against candidate lines. - Keep final 3-5 lines that satisfy length and uniqueness checks. - If fewer than 3 survive, regenerate with stricter prompt constraints. 6. Return API response: - Follow `references/output-schema.json`. - Return final lines plus evidence URLs from Douban/encyclopedia retrieval. ## Guardrails - Respect robots and rate limits; cache page fetches by URL. - Avoid sensitive, discriminatory, or explicit wording in slogans. - Keep language punchy and cinematic; avoid spoilers and plot twists. - Always validate line length in code, not by model assumption. ## Resources - `references/prompt-template.md`: system/user prompt templates. - `references/source-extraction.md`: context extraction field rules. - `references/output-schema.json`: API output contract. - `scripts/validate_slogans.py`: strict 12-Chinese-character validator. --- > Source: [microwind/design-patterns](https://github.com/microwind/design-patterns) — distributed by [TomeVault](https://tomevault.io).
