An interactive setup command for a Bash and shell-script development environment. It installs a language server, ShellCheck for finding shell-script problems, and shfmt for formatting shell code.

Use it to install and verify Bash development tools, enable language-server support in Claude Code, and test linting and formatting on a shell script.

It gathers the required tools and checks their versions in one setup flow. This helps an agent or developer get code checking and editor support working consistently.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/zircote/bash-lsp

Made for: Claude Code.

Or install bash-lsp, the plugin that ships this one along with the rest of its 1 command.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00008	$0.00269
Opus 5.5	$0.00003	$0.00108
Sonnet 5.5	$0.00002	$0.00054
Haiku 4.5	$0.00001	$0.00027

Measured 1mo ago against content hash 8c8297a1a6d3, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

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 1mo 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.

Bash LSP Setup

This command will configure your Bash/Shell development environment with bash-language-server and essential tools.

Prerequisites Check

First, verify Node.js is installed:

node --version
npm --version

Installation Steps

1. Install bash-language-server

npm install -g bash-language-server

2. Install Development Tools

# Linting

shfmt --version

4. Enable LSP in Claude Code

export ENABLE_LSP_TOOL=1

Verification

Test the LSP integration:

# Create a test file
cat > test_lsp.sh << 'EOF'
#!/bin/bash
greet() {
    local name="$1"
    echo "Hello, $name!"
}
greet "World"
EOF

# Run ShellCheck

# Run shfmt
shfmt -w test_lsp.sh

# Clean up
rm test_lsp.sh

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.
