Deployment Gates & Quality Checks

Code review is the entry point, but Claude Code can participate in every stage of the CI/CD pipeline. The pattern is always the same: pipe context into Claude via --print, constrain tools with --allowedTools, and use the output to make a pass/fail decision.

Pre-merge gate: after tests pass and linting is clean, run Claude as a final review that checks for things automated tools miss. Does the migration file match the schema change? Does the API version bump match the breaking change? Is the error handling consistent with the rest of the codebase? These are judgment calls that linters cannot make but Claude can, because Claude has read your CLAUDE.md and understands your team's conventions.

Post-deploy monitoring is the less obvious but equally valuable integration. When your deployment pipeline ships to staging, pipe the deploy log into Claude: "Analyze this deployment log. Flag any warnings, errors, or anomalies that suggest the deploy may have issues." Claude can catch log patterns that your monitoring dashboards miss — subtle warnings buried in verbose output, error counts that are technically below threshold but trending upward, configuration changes that do not match the expected diff.

The constraint is latency. Claude is not a real-time monitoring tool. A Claude analysis adds 30-60 seconds to your pipeline. For pre-merge gates, that is acceptable — you are already waiting for tests to run. For post-deploy monitoring, it is a complement to real-time alerts, not a replacement. Run Claude analysis asynchronously and post results to Slack or a monitoring channel.

1. 1. Start with PR Review The GitHub Action is the lowest-friction entry point. Set it up, let it run for a week, and calibrate based on what it catches and what it misses. Add rules to CLAUDE.md to improve its review quality over time.
2. 2. Add Pre-Merge Analysis After PR review is tuned, add a pre-merge step that checks for cross-cutting concerns: migration consistency, API contract changes, dependency updates that might need additional review. This runs after tests pass, before the merge button is enabled.
3. 3. Add Post-Deploy Monitoring Pipe deployment logs into Claude asynchronously. Post results to your monitoring channel. Do not gate deployments on Claude analysis — use it as an early warning system that runs in parallel with your existing monitoring.
4. 4. Build Deployment Documentation Have Claude generate release notes from the merged PRs since the last deploy. Pipe the git log and PR descriptions into --print with a release notes template. Automate the one task that every team hates and no one does consistently.
