LSP Development Skill

An installable Codex and Claude skill for building Language Server Protocol servers and editor integrations.

The skill covers protocol capability negotiation, document sync, completion, hover, signature help, diagnostics, definitions, references, semantic tokens, rename, code actions, workspace indexing, client/server wiring, packaging, testing, and performance-sensitive editor behavior.

Install

Use npm without a global install:

npx @explorer_kasmir/lsp-dev-skill install codex
npx @explorer_kasmir/lsp-dev-skill install claude

Install into an explicit skills directory:

npx @explorer_kasmir/lsp-dev-skill install --target ~/.codex/skills
npx @explorer_kasmir/lsp-dev-skill install --target ~/.claude/skills

Replace an existing install:

npx @explorer_kasmir/lsp-dev-skill install codex --force
