เหตุใดจึงต้องมีคลัง PromptRegistry

ฟิลด์หลักของสิ่งประดิษฐ์พรอมต์

การออกแบบโครงสร้างฐานข้อมูล

-- prompts table: one row per unique prompt identity
CREATE TABLE prompts (
  prompt_id   VARCHAR(100) PRIMARY KEY,
  description TEXT,
  created_at  TIMESTAMP DEFAULT NOW()
);

-- prompt_versions table: one row per versioned artifact
CREATE TABLE prompt_versions (
  id          SERIAL PRIMARY KEY,
  prompt_id   VARCHAR(100) REFERENCES prompts(prompt_id),
  version     VARCHAR(20)  NOT NULL,
  template    TEXT         NOT NULL,
  author      VARCHAR(100),
  tags        TEXT[],
  model       VARCHAR(50),
  is_active   BOOLEAN DEFAULT FALSE,
  created_at  TIMESTAMP DEFAULT NOW(),
  UNIQUE(prompt_id, version)
);

การออกแบบคลังแบบใช้ไฟล์
