Backend Reliability Bundle
The Backend Reliability Bundle combines four focused production-review skills for teams building APIs, databases, queues, workers and webhook integrations.
Use the bundle to detect breaking API changes, unsafe database migrations, duplicate or lost background work, unreliable webhook delivery, incomplete recovery controls and missing release tests.
Each skill performs a structured, read-only audit and returns an evidence-based verdict, a 100-point score, severity-ranked findings, exact remediation, required verification tests and clear release conditions.
The bundle can be used as one coordinated backend-release workflow or each skill can be applied independently to a specific production risk.
Works with every agent that reads SKILL.md — Claude Code, Cursor, Codex CLI, Gemini CLI, GitHub Copilot, Windsurf, OpenClaw, and more.

API Contract Drift Detector
Example session with this skill installed
Compare the attached openapi.yaml with the user_controller.py implementation. Check for field mismatches, missing status codes, and potential breaking changes for the mobile app client.
- Read your context and instructions
- Compiled the api contract drift
Verdict: Material contract drift (Score: 68/100). Found 3 critical mismatches:
- Server returns 'phone_verified' as a boolean, but spec defines it as string.
- Implementation missing 409 Conflict response defined in spec.
- Mobile client expects 'id' as integer while server sends UUID string.
