An interactive setup command for a LaTeX development environment. LaTeX is a system for creating documents from marked-up text; the command configures Texlab, a LaTeX language server, and related checking tools.

Use it to check for a TeX installation, install Texlab and ChkTeX, verify their versions, and optionally set up Latexmk for automated builds.

It removes the manual work of installing and checking the tools needed for editor support, linting, and document building.

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.

npx agentmods add commands/zircote/latex-lsp/setup

Clone the repo

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

Per session 10 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 925 The whole file, excluding the scripts and references it only reads on demand.

Security scan B 1 finding. Scan, not verified.

Origin original No closer match found in the catalogue.

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	$0.00010	$0.00925
Opus 5	$0.00005	$0.00463
Sonnet 5	$0.00002	$0.00185
Haiku 4.5	$0.00001	$0.00093

Security

Grade B, and why

setup scanned grade B with 1 finding 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 yesterday.

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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

LaTeX LSP Setup

This command will configure your LaTeX development environment with Texlab LSP and essential tools.

Prerequisites Check

First, verify a TeX distribution is installed:

pdflatex --version || xelatex --version || lualatex --version

If not installed, install a TeX distribution:

macOS: brew install --cask mactex or brew install --cask basictex
Linux: sudo apt install texlive-full (Debian/Ubuntu) or sudo dnf install texlive-scheme-full (Fedora)
Windows: Download and install MiKTeX or TeX Live

Installation Steps

1. Install Texlab LSP Server

Option 1: Cargo (recommended)

cargo install --locked texlab

Option 2: Package Manager

# macOS
brew install texlab

# Arch Linux
sudo pacman -S texlab

# Fedora
sudo dnf install texlab

2. Install ChkTeX (LaTeX Linter)

# macOS
brew install chktex

# Debian/Ubuntu
sudo apt install chktex

# Fedora
sudo dnf install chktex

# Arch Linux
sudo pacman -S chktex

3. Verify Installation

# Check Texlab
texlab --version

# Check ChkTeX
chktex --version

# Check LaTeX
pdflatex --version

4. Optional: Install Latexmk (Build Automation)

# Usually included with TeX Live
latexmk --version

# If not available, install TeX Live extras
sudo apt install latexmk  # Debian/Ubuntu

5. Enable LSP in Claude Code

export ENABLE_LSP_TOOL=1

Configuration (Optional)

Texlab Configuration

Create texlab.toml or .texlabrc in your project root:

[build]
executable = "latexmk"
args = ["-pdf", "-interaction=nonstopmode", "-synctex=1", "%f"]
onSave = false

[chktex]
onEdit = true
onOpenAndSave = true

[formatting]
lineLength = 80

ChkTeX Configuration

Create .chktexrc in your project root to customize warnings:

# Disable specific warnings
-n1  # Command terminated with space
-n2  # Non-breaking space (~) should be used
-n8  # Wrong length of dash

# Set tabsize
TabSize = 2

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.

setup is a command published in the GitHub repository zircote/latex-lsp (1 stars, last pushed 21d ago), licensed MIT. It adds 10 tokens to every session and 925 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
