swift-lsp

swift-lsp is a plugin for Claude Code from MSApps-Mobile/claude-plugins. Its manifest loads nothing; the 1 skill it bundles cost 73 tokens per session together, scanned A, a copy of kotlin-lsp, MIT.

A Claude connection to SourceKit-LSP, Apple's language server for Swift. It supplies diagnostics, definition and reference navigation, and type information without changing project files.

In plain words
What is it for?
Use it to inspect Swift errors and warnings, go to definitions, find references, and check type information during code changes.
Why use it?
It helps the agent understand Swift code and catch errors while working on iOS or macOS projects.

Security

Grade A, and why

swift-lsp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

86% identical to kotlin-lsp — 15 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 73 tokens a session between them. Each is measured on its own page, and each can be installed alone.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
