Lsp Setup

What it does

When your agent uses it

• You need deeper code understanding and no LSP server is configured
• The user asks to set up
• Configure an LSP server

Example prompts

• “/lsp-setup”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

1. 1Ask the language — use ask_user to ask which programming language(s) the user wants LSP support for
2. 2Detect the OS — run uname -s (or check for Windows via $env:OS / %OS%) to determine macOS, Linux, or Windows
3. 3Look up the LSP server — read references/lsp-servers.md for known servers, install commands, and config snippets
4. 4Ask scope — use ask_user to ask whether the config should be user-level (~/.copilot/lsp-config.json) or repo-level (lsp.json at the repo…
5. 5Install the server — run the appropriate install command for the detected OS
6. 6Write the config — merge the new server entry into the chosen config file (~/.copilot/lsp-config.json for user-level; lsp.json or…
7. 7Verify — confirm the LSP binary is on $PATH and the config file is valid JSON

What it can do on your machine

Read from SKILL.md and the folder at commit 727ff2e. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • code.visualstudio.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Lsp Setup loads about 996 tokens when it runs, and up to ~3.2k if it reads all its reference files. Until then it costs about 108 tokens; SKILL.md has 459 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~108

When it runs · the whole SKILL.md, loaded when a task matches

~996

With references · SKILL.md plus every file in references/, read only if the agent opens them

~3.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Enable code intelligence (go-to-definition, find-references, hover, type info) for any programming language by installing and configuring an LSP server for Copilot CLI. Detects the OS, installs the right server, and generates the JSON configuration (user-level or repo-level). Use when you need deeper code understanding and no LSP server is configured, or when the user asks to set up, install, or configure an LSP server.
