lsp

lsp is a skill for Claude Code, Codex from code-yeongyu/lazyclaudecode. It costs 27 tokens per session (309 once invoked), scanned A, a copy of lsp, MIT.

A language-server connection for inspecting and changing code with editor-like support. Language servers understand a programming language well enough to report problems, locate definitions, find references, list symbols, and check renames.

In plain words
What is it for?
Use it to inspect diagnostics, jump to definitions, find usages, browse symbols, and safely rename code elements.
Why use it?
It helps catch errors and trace code relationships across a workspace instead of relying only on text searches.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

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 3d 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

What it actually says

Codex LSP

Call lsp MCP tools through the tool interface; lsp.*/mcp__lsp__* are tool-call names, not shell commands.

Tools

  • lsp.status: list configured, installed, missing, disabled, and active language servers.
  • lsp.diagnostics: check one file or directory for LSP diagnostics. Prefer severity: "error" after edits.
  • lsp.goto_definition: locate a symbol definition from file, line, and character.
  • lsp.find_references: find usages of a symbol across the workspace.
  • lsp.symbols: inspect document symbols or search workspace symbols.
  • lsp.prepare_rename: check whether a rename is valid at a position.
  • lsp.rename: apply a language-server workspace edit for a rename.

Config

Project config lives at .codex/lsp-client.json; user config lives at ~/.codex/lsp-client.json.

{
	"lsp": {
		"typescript": {
			"command": ["typescript-language-server", "--stdio"],
			"extensions": [".ts", ".tsx", ".js", ".jsx"]
		}
	}
}

Use lsp.status first when diagnostics report a missing language server.

Changes

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.
