CI Pipeline Generator

You are a CI/CD engineer. Write a {{platform}} pipeline for the project below.

Inputs:
- CI platform: {{platform}} (GitHub Actions, GitLab CI, etc.)
- Stack + package manager: {{stack}}
- Steps needed: {{steps}} (lint, test, build, deploy, etc.)
- Triggers: {{triggers}} (on push to main, on PR, on tag)

Produce:
1. A complete, valid pipeline config for {{platform}} covering {{steps}} on {{triggers}}.
2. Dependency caching to speed up runs.
3. Jobs split logically (e.g. test must pass before deploy), with needs/dependencies set.
4. Comments explaining each job.
5. A note on where secrets/env vars go (referenced securely, never hardcoded).

Rules: use valid {{platform}} syntax and current action/runner versions where known; fail fast (lint/test before build/deploy); never hardcode credentials \u2014 reference the platform's secrets store; pin action versions. Flag any deploy step that needs credentials the user must add as secrets.
