SDK development, external developer communication, code samples, API client libraries, community engagement, and developer experience. Use when creating SDKs, writing external guides, creating code samples, or improving developer experience.
Profile systems, identify bottlenecks, optimize code and infrastructure for speed, throughput, and resource efficiency.
This skill should be used when implementing code quality standards, setting up linting/testing/security scans, enforcing coverage thresholds, or establishing CI/CD guardrails.

REST/gRPC API design, versioning strategies, error codes, request/response contracts, backward compatibility, rate limiting, OpenAPI specifications. Use when designing APIs, defining contracts, planning versioning, or ensuring API consistency.
Hermetic builds, dependency management, build caching, reproducible builds, cross-compilation, build optimization. Use when optimizing build speed, ensuring reproducibility, or designing build infrastructure.
Secrets management, environment-specific configs, safe defaults, feature flags, configuration-as-code, compliance and audit trails. Use when managing secrets, configuring deployments, or implementing feature flags.
Version updates (major/minor/patch), security patch application, transitive dependency resolution, monorepo dependency management, deprecation tracking, license compliance. Use when updating dependencies, managing versions, or addressing CVEs.
