Skill UI

Guides Go distributed-system engineers through protobuf layout, interceptor design, error handling, TLS/mTLS setup, bufconn testing, and streaming RPC patterns so they can implement, review, and debug real-world gRPC servers and clients with production-grade operability.

This skill acts as a Go modernization engineer, keeping codebases current with the latest Go idioms and standard library improvements. It proactively detects deprecated APIs, outdated patterns, and suggests adopting modern features (like `errors.Is`, `slog`, etc.). It supports both inline, contextual suggestions during active coding, and full-scan review for CI/CD pipelines, ensuring code safety, correctness, and readability.

This comprehensive guide covers all idiomatic naming conventions in Go (Golang), including rules for packages, structs, constants, functions, and errors. Use this skill when writing new Go code, reviewing existing code, or debating naming choices to ensure your code adheres to Go's standards, such as MixedCaps usage and avoiding 'stuttering'.

A comprehensive skill for engineering high-quality, observable Go services. It guides best practices across five key signals: structured logging (slog), Prometheus metrics, OpenTelemetry tracing, continuous profiling (pprof), and RUM. Use this when instrumenting new features, reviewing PRs, or auditing entire codebases to ensure systems are fully measurable for reliable diagnosis and alerting.

Defensive Golang guidance for avoiding panics, nil traps, append aliasing, overflow, float comparison bugs, and resource leaks. Useful for writing safer code and reviewing runtime risks.

A comprehensive skill set for senior Go security engineers, providing structured methodologies for identifying and mitigating vulnerabilities. It teaches defense-in-depth principles, utilizes Threat Modeling (STRIDE), and scores risks using DREAD. Modes include detailed Review (PR security checks), full Audit (parallel vulnerability scanning), and Coding (secure implementation). Essential for auditing, reviewing, or developing any Go application that handles sensitive data.

Fetches a Gmail message by ID and extracts its body or headers, with options for text or JSON output, HTML decoding, and dry-run previews to streamline email inspection in scripts.

Command-line skill for sending Gmail messages with recipients, subject, body, HTML, attachments, CC/BCC, drafts, and a dry-run preview so automation scripts can deliver reports or notifications while respecting RFC encoding.

Google Workflow command surfaces your next meeting’s agenda, attendees, and linked docs so you can quickly review what’s coming and which calendar it belongs to.

A comprehensive skill for managing, reading, creating, and editing content within Feishu Cloud Docs, Wiki, and Docx formats. It supports the full lifecycle of document interaction, including summarizing, translating, reviewing, and restructuring content. Crucially, it can extract and process embedded elements such as electronic spreadsheets, multi-dimensional tables, and visual whiteboards, ensuring deep interaction with complex knowledge bases.

Checks Microsoft SDK code by verifying API signatures, fetching docs, and finding Azure samples before writing or reviewing code that touches .NET or Microsoft APIs.

Generates a single formula-driven Excel dashboard from CSV/tabular data, complete with KPI cards, charts, sparklines, and conditional formatting so analysts can instantly review metrics and share an executive-ready .xlsx output.
