    Rate Limit Contract Repair

    Rate Limit Contract Repair

    Example session with this skill installed

    Middleware uses 50 req/min but docs say 100. The SDK retries 429s immediately. Align the repo contract and add tests using the existing fake-clock utility. Do not touch production.

    • Read your context and instructions
    • Compiled the rate limit contract

    Repair decision

    RATE-LIMIT CONTRACT DRIFT FOUND. I have centralized the quota in config/limits.ts, updated the SDK to honor Retry-After, and added 12 deterministic tests. Deployed behavior remains unverified.

    About this skill

    The problem

    Rate limit behavior often drifts across repository middleware, route overrides, and public documentation. This leads to client retry storms, broken SDKs, and inconsistent API enforcement that is difficult to debug without production access.

    What it does

    • Identifies conflicting quotas, windows, and identities across source code, OpenAPI specs, and docs.
    • Traces enforcement paths from identity extraction to response serialization and header handling.
    • Standardizes 429 response schemas, Retry-After headers, and SDK retry logic.
    • Generates safe repository patches to centralize magic numbers and unify policy definitions.
    • Provides a deterministic test matrix using fake clocks and mocked adapters for local verification.

    Frameworks & tools

    Compatible with any repository containing Express, FastAPI, TypeScript, Python, OpenAPI, GraphQL, or standard HTTP client SDKs.

    Why this beats prompting it yourself

    Manual review misses the subtle drift between a middleware default and a hard-coded route override. This skill enforces a strict contract register that captures every source of truth, ensuring your patches are reviewable and tests are truly deterministic.

    Use cases

    • Aligning middleware quotas with OpenAPI specifications and public documentation.
    • Fixing SDKs that retry unsafe mutations or ignore Retry-After headers.
    • Unifying mixed rate-limit identities like user-based vs tenant-based scopes.
    • Standardizing response formats across different service mocks and test suites.

    Known limitations

    Cannot access live Redis instances, production gateways, or real customer traffic logs. It does not perform production migrations or verify deployed quotas.

    No access to live Redis, production gateways, or customer data. Cannot verify deployed behavior or perform database migrations. Requires repository-based evidence for all findings.

    What's inside

    Frequently Asked Questions

    This skill scans your entire repository—including middleware, route logic, OpenAPI specs, and SDKs—to find conflicting rate-limit values and unify them into a single, consistent source of truth via safe repository patches.

    The skill is designed for repositories using popular frameworks like Express, FastAPI, and GraphQL, and works with common languages such as TypeScript and Python.

    No, the skill operates strictly on your source code and documentation; it does not require or support access to live Redis instances, production gateways, or real-time traffic logs.

    You receive the full skill logic and the deterministic test matrix generator, which uses fake clocks and mocked adapters to verify that your rate-limit patches work correctly before deployment.

    It identifies mismatches between your API's 429 response behavior and your SDK's retry logic, ensuring that SDKs correctly honor Retry-After headers and avoid 'retry storms' on unsafe mutations.
