    convention-learner

    Detects and enforces project-specific coding conventions by analyzing existing codebase patterns. Learns naming conventions, folder structure, test organization, and coding style from the existing code. Load when: "conventions", "coding standards", "project patterns", "enforce style", "detect patterns", "learn conventions", "code consistency".

    caching

    Caching strategies, invalidation, eviction policies, HTTP caching, distributed caching, and anti-patterns. Use when designing cache layers, choosing eviction policies, debugging stale data, or optimizing read-heavy workloads.

    logging

    Logging best practices for Java (SLF4J/Logback) and Node.js (Winston/Pino). Use for structured logging, log levels, and avoiding sensitive data exposure.

    resilience

    Apply resilience patterns (retry, backoff, circuit breaking) when writing or reviewing code that makes outbound HTTP/REST calls, database operations, or any I/O that can experience transient failures. Use this skill when: (1) writing new code that calls external services or APIs, (2) reviewing code that uses fetch, HTTP clients, or service-to-service calls, (3) adding queue consumers or workers that interact with remote systems, (4) debugging intermittent failures in production.

Error Handling

When to use

  • Implement explicit failure semantics, bounded retries and recovery.

Not for: debugging for a defect; incident-response for live containment.

Steps

  1. Identify operations, failure classes, ownership and user consequences.
  2. Choose consistent boundary errors or results, preserve causes and sanitize public output.
  3. Retry only transient failures with budgets and safe idempotency; add timeouts, cancellation or circuits when required.
  4. Exercise real code with controlled failure inputs and verify recovery, telemetry and user feedback.

Verify

  • Errors are not swallowed; retries terminate and repeated actions and recovery have evidence.

References

  • engineering-principles.md — shared decision boundaries, scope and verification.
  • error-resilience.md — system-level resilience architecture (cross-layer error propagation, failure posture); this skill is its implementation-level companion
