Primeros pasos con Pipelines e IA

Puedes usar System prompts o SKILLs en tu Pipeline para automatizar tareas.

Ejemplo usando Codex en GitHub Actions

Codex puede convertir una issue de GitHub en artefactos de planificación de OpenSpec. En este patrón, un mantenedor aplica la etiqueta /create-spec, el workflow guarda el contexto completo de la issue en archivos y openai/codex-action se ejecuta con acceso de escritura limitado al workspace del repositorio.

name: Create OpenSpec from an issue with Codex

on:
  issues:
    types: [labeled]

permissions:
  contents: write
  issues: write
  pull-requests: write

jobs:
  create-spec:
    if: github.event.label.name == '/create-spec'
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v5

      - name: Read full issue context
        env:
          GH_TOKEN: ${{ github.token }}
          ISSUE_NUMBER: ${{ github.event.issue.number }}
          REPOSITORY: ${{ github.repository }}
        run: |
          mkdir -p .codex/issue
          gh api "repos/${REPOSITORY}/issues/${ISSUE_NUMBER}" > .codex/issue/issue.json
          jq -r '.title // ""' .codex/issue/issue.json > .codex/issue/title.txt
          jq -r '.body // ""' .codex/issue/issue.json > .codex/issue/body.md

      - name: Ask Codex to create OpenSpec artifacts
        uses: openai/codex-action@v1
        with:
          openai-api-key: ${{ secrets.OPENAI_API_KEY }}
          sandbox: workspace-write
          prompt-file: .codex/issue/create-openspec-prompt.md

El workflow completo incorpora varias medidas para un uso en producción: trata el texto de la issue como entrada de planificación no confiable, pide a Codex que cree un resumen saneado, limita los cambios a documentation/openspec, delega el commit y la creación de la pull request a pasos deterministas del workflow e informa del resultado en la issue. Configura el secreto de repositorio OPENAI_API_KEY antes de usarlo.
