Design multi-stage CI/CD pipelines with approval gates, security checks, and deployment orchestration. Use this skill when designing zero-downtime deployment pipelines, implementing canary rollout strategies, setting up multi-environment promotion workflows, or debugging failed deployment gates in CI/CD.

Architecture patterns for multi-stage CI/CD pipelines with approval gates, deployment strategies, and environment promotion workflows.
Design robust, secure deployment pipelines that balance speed with safety through proper stage organization, automated quality gates, and progressive delivery strategies. This skill covers both the structural design of pipeline architecture and the operational patterns for reliable production deployments.
Detailed pattern documentation lives in references/details.md. Read that file when the navigation tier above is insufficient.
The pipeline health check is hitting a shallow /ping endpoint that returns 200 even when the database is unreachable. Use a deep readiness check that verifies actual dependencies (see Health Checks section above).
Argo Rollouts requires a valid AnalysisTemplate to auto-promote. If the Prometheus query returns no data (e.g., metric name changed), the analysis stays inconclusive and promotion stalls. Add inconclusiveLimit so the rollout fails fast rather than hanging:
spec:
metrics:
- name: error-rate
failureCondition: "result[0] > 0.05"
inconclusiveLimit: 2 # fail after 2 inconclusive results, not hang indefinitely
provider:
prometheus:
query: |
sum(rate(http_requests_total{status=~"5.."}[2m]))
/ sum(rate(http_requests_total[2m]))
Check that production environment protection rules are configured — a missing reviewer assignment means the approval gate waits indefinitely with no notification. In GitHub Actions, ensure Required reviewers is set to an existing user or team in Settings → Environments → production.
If COPY . . appears before dependency installation, any source file change invalidates the dependency layer. Reorder to copy dependency manifests first:
# Good: dependencies cached separately from source code
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build
A service rollback without a migration rollback causes schema/code mismatch errors. Always make migrations backward-compatible (additive only) for at least one release cycle, and keep undo scripts versioned alongside the migration:
# migrations/V20240315__add_nullable_column.sql (forward)
# migrations/V20240315__add_nullable_column.undo.sql (backward)
Never run destructive migrations (DROP COLUMN, ALTER NOT NULL) until the old code version is fully retired from all environments.

Use after generating code, after accepting AI suggestions, or when reviewing AI-written modules. Also use when code works but feels brittle, when error handling seems thin, when orphaned resources or missing cleanup are suspected, or when the agent claims done but hidden debt may exist. Catches the specific failure patterns AI agents produce that humans would not.
