LSP Setup

Detects the languages in your project, installs and configures the right language server, then verifies it with a real diagnostics roundtrip.

Dev & CodingIntermediate★ 67,531⑂ 5,507AI score 9/10Last updated: Aug 9, 2026

What it does

  • Routes by file extension (.ts, .py, .go, .rs, .kt, .swift and ~20 languages) to the exact per-language reference.
  • Runs detect-lsp.ts to scan a project and report each language's builtin server id, whether the executable is on PATH, an install hint, and config status (--json supported).
  • Supplies per-OS install commands (macOS/Linux/Windows) plus ready-to-paste snippets for .codex/lsp-client.json and .opencode/lsp.json.
  • Runs verify-lsp.ts for a real diagnostics roundtrip that reports OK / FAIL / SKIP with exit codes.
  • Explains how to choose between competing servers (basedpyright vs pyright vs ty vs ruff) and the priority / initialization / disabled override rules.

Who it's for

  • Developers hitting "no LSP server configured" or "server not installed" in editors or coding agents.
  • Teams on polyglot monorepos who need diagnostics, go-to-definition, find-references and rename to work everywhere.
  • Users of the Codex or OpenCode/omo harnesses editing LSP config files.

Examples

  1. "Scan this repo and install every missing language server" → detect, then install only what's absent using the OS-specific hint.
  2. "Python diagnostics are silent" → open the Python reference, install basedpyright, set priority, confirm with verify-lsp.ts app.py.
  3. "I need a custom in-house server" → define command and extensions in the user config ~/.codex/lsp-client.json, since non-builtin ids are ignored in project configs.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/code-yeongyu/oh-my-openagent/HEAD/packages/shared-skills/skills/lsp-setup/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the packages/shared-skills/skills/lsp-setup folder from the GitHub repo code-yeongyu/oh-my-openagent into my ~/.claude/skills/lsp-setup/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/code-yeongyu/oh-my-openagent.git /tmp/oh-my-openagent && mkdir -p ~/.claude/skills && cp -r /tmp/oh-my-openagent/packages/shared-skills/skills/lsp-setup ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Install Bun first (the scripts need it): curl -fsSL https://bun.sh/install | bash
  2. Clone the repository: git clone https://github.com/code-yeongyu/oh-my-openagent.git /tmp/oh-my-openagent
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r /tmp/oh-my-openagent/packages/shared-skills/skills/lsp-setup ~/.claude/skills/
  5. Verify with ls ~/.claude/skills/lsp-setup that references/ and scripts/ came along.
  6. Restart Claude Code and ask something like "set up the LSP for this TypeScript project" to trigger it.
