Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
vara-skills
by gear-foundation
Use when a builder needs the top-level router for the provisional standard Gear/Vara Sails skill pack across Codex, Claude, or OpenClaw. Covers standard Sails apps and ethexe-specific work via dedicated skills. Do not use for non-Sails programs or broad protocol research.

defense-in-depth
by lv416e
"Use when invalid data causes failures deep in execution, requiring validation at multiple system layers - validates at every layer data passes through to make bugs structurally impossible 無効なデータが実行の深い部分で障害を引き起こす場合、複数のシステム層での検証が必要な際に使用 - データが通過するすべての層で検証し、バグを構造的に不可能にする"
zig
by nzrsky
Up-to-date Zig programming language patterns for version 0.15.2. Use when writing, reviewing, or debugging Zig code, working with build.zig and build.zig.zon files, or using comptime metaprogramming. Critical for avoiding outdated patterns from training data - especially build system APIs (root_module instead of root_source_file, addLibrary with linkage), I/O APIs (buffered writer pattern), container initialization (.empty/.init), allocator selection (DebugAllocator), ArrayList now unmanaged by default, @typeInfo lowercase fields (.@"struct" not .Struct), and removed language features (async/await, usingnamespace).
insecure-defaults
by lv416e
"Detects fail-open insecure defaults (hardcoded secrets, weak auth, permissive security) that allow apps to run insecurely in production. Use when auditing security, reviewing config management, or analyzing environment variable handling."
test-driven-development
by lv416e
"Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first 機能やバグ修正を実装する際、実装コードを書く前に使用 - まずテストを書き、失敗を確認し、最小限のコードで通す。最初に失敗を求めることで、テストが実際に動作を検証することを保証"
