AI Prompt CI/CD: Automate Prompt Testing and Safe Deployment

Why Prompts Need CI/CD

Traditional software has CI/CD. Prompts are software too — they need the same rigor:

Setting Up Prompt CI/CD

GitHub Actions Integration

name: Prompt CI/CD

on:

pull_request:

paths: ['prompts/**']

jobs:

evaluate:

runs-on: ubuntu-latest

steps:

- uses: actions/checkout@v4

- name: Run prompt evaluation

run: |

npx promptshelf evaluate \

--prompt prompts/email-classifier.yaml \

--test-suite tests/email/ \

--min-quality 85 \

--max-regression 5

Quality Gate Rules

gate:

min_quality: 85 # Minimum quality score (0-100)

max_regression: 5 # Max quality drop from previous version

max_latency_ms: 3000 # Max response time

max_cost_usd: 0.01 # Max cost per call

min_pass_rate: 0.90 # Min test pass rate

Canary Deployment

Route 5% of traffic to the new prompt version. Monitor quality metrics for 24 hours. If metrics hold, increase to 100%.

Summary

Prompt CI/CD is essential for production AI applications. PromptShelf provides the infrastructure — you provide the test cases.
