Guidelines for efficient Xcode MCP tool usage via mcporter CLI. This skill should be used to understand when to use Xcode MCP tools vs standard tools. Xcode MCP consumes many tokens - use only for build, test, simulator, preview, and SourceKit diagnostics. Never use for file read/write/grep operations. Use this skill whenever working with Xcode projects, iOS/macOS builds, SwiftUI previews, or Apple platform development. 来源：https://prompts.chat/prompts/cmms43gs50004jy042djn2324
A read-only maintenance audit workflow for Agent Skills. Reviews existing skills for stale or version-sensitive guidance, trigger conflicts, overlap, broken references, unsafe helper behavior, specification drift, context bloat, and outdated technology assumptions. Verifies material freshness claims against authoritative sources and reports only evidence-backed maintenance findings without modifying the audited skills. 来源：https://prompts.chat/prompts/cmuwbt3p80004qs06iif6z1q1
Decodes a JWT without trusting it and lints the header and claims: alg none, remote jku/x5u keys, missing or expired exp, nbf/iat clock skew, millisecond timestamps, long lifetimes, iss/aud mismatches, sensitive data in the payload, and HMAC signature checks with a secret from an env var. Use when a login or API call fails with 401, or when reviewing token settings. Includes a stdlib Python inspector with --self-test. 来源：https://prompts.chat/prompts/cmvexfiys000njr08n2k8i3bq
