config-drift-checker Canary Gate
The config-drift-checker Canary Gate is a release discipline for agencies running Claude Code for multiple clients. Instead of letting model or Claude Code updates silently break CLAUDE.md files, skills, or hooks, you pin each client's baseline to a specific model and version. On a schedule you control, config-drift-checker canaries new releases in a throwaway repo copy, running automated test cases generated from the client's own setup. Only after two green canaries does it open a PR, which you review before merging to the client's production config. This gate turns a $49 per month GitHub Actions cost plus your Anthropic API spend into a billable reliability retainer. For example, an agency managing ten Claude Code clients can charge a $1,800 setup audit plus a monthly monitoring fee, using the canary PR as tangible proof of delivery. The gate fails fast, so regressions never reach client workflows.
