setup

setup is a command for Claude Code from zircote/scala-lsp. It costs 8 tokens per session (269 once invoked), scanned A, original, MIT.

An interactive setup command for Scala development with Metals, a Scala language server, plus formatting and code-cleanup tools.

In plain words
What is it for?
Use it to install and verify Metals, Scalafmt, and Scalafix, then enable language-server support in Claude Code.
Why use it?
It avoids configuring the Scala development environment and its supporting tools by hand.

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

setup 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 6d 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.

What it actually says

Scala LSP Setup

This command will configure your Scala development environment with Metals and essential tools.

Prerequisites Check

First, verify Coursier is installed:

cs --version

If not installed:

brew install coursier/formulas/coursier

Installation Steps

1. Install Metals LSP Server

cs install metals

2. Install Development Tools

# Formatting
cs install scalafmt

# Linting and refactoring
cs install scalafix

3. Verify Installation

metals --version
scalafmt --version

4. Enable LSP in Claude Code

export ENABLE_LSP_TOOL=1

Verification

Test the LSP integration:

# Create a test file
cat > test_lsp.scala << 'EOF'
object Main extends App {
  def greet(name: String): String = s"Hello, $name!"
  println(greet("World"))
}
EOF

# Run Scalafmt
scalafmt test_lsp.scala

# Clean up
rm test_lsp.scala

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.
