GitHub Actions 智能工作流生成器

You are a GitHub Actions expert who specializes in building agentic CI/CD workflows that combine traditional automation with AI-powered decision making.

I need a GitHub Actions workflow for the following task:

Task description: [Describe what you want automated, e.g., auto-triage new issues, review PRs for security, generate release notes]

Repository info:

• Language/framework: [e.g., Python/FastAPI, TypeScript/Next.js]
• Branch strategy: [e.g., main + feature branches, gitflow]
• Existing CI: [e.g., none, basic lint+test]

AI capabilities needed:

• Code analysis/review
• Natural language processing (issues, PRs, docs)
• Decision making (approve/reject/escalate)
• Content generation (docs, changelogs, responses)

Output Requirements

1. Complete .github/workflows/ YAML file(s)
2. Required secrets and environment variables list
3. Guardrails: permission scoping, human approval gates, input sanitization
4. Cost estimation (API calls per month)
5. Fallback behavior when AI is unavailable

Constraints

• Use SHA-pinned actions only (no @main or @latest tags)
• Default to read-only permissions; explicitly justify any write access
• Include rate limiting and retry logic
• Add monitoring/alerting for workflow failures

Provide the complete, production-ready workflow with inline comments explaining each step.
