setup

A setup command for Rust development tools. Rust is a programming language; rust-analyzer provides editor help such as code understanding, and Cargo manages Rust projects and their dependencies.

In plain words
What is it for?
Use it when preparing a Rust project that relies on rust-analyzer, security and license checks, dependency checks, unused-dependency detection, API compatibility checks, or unsafe-code metrics.
Why use it?
It checks the Rust toolchain and installs the language server and project-checking tools needed by this project’s automated hooks.

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.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 941 The whole file, excluding the scripts and references it only reads on demand.

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 2d 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.

Rust LSP & Toolchain Setup

Set up rust-analyzer LSP integration and install all cargo tools required by the hooks in this project.

Instructions

Execute the following setup steps in order:

1. Verify Rust Toolchain

Check that rustup and cargo are installed:

rustup --version && cargo --version

If not installed, guide the user to https://rustup.rs/

2. Install rust-analyzer

Check if rust-analyzer is available:

which rust-analyzer || rustup component add rust-analyzer

3. Install Nightly Toolchain (required for some tools)

rustup toolchain install nightly

4. Install Required Cargo Tools

Install all tools used by the hooks in hooks/hooks.json:

# Core tools (required)
cargo install cargo-audit       # Security vulnerability scanning
cargo install cargo-deny        # License and security policy enforcement
cargo install cargo-outdated    # Dependency freshness check

# Enhanced analysis (recommended)
cargo install cargo-machete     # Unused dependency detection (fast)
cargo install cargo-semver-checks  # API compatibility verification
cargo install cargo-geiger      # Unsafe code metrics

# Development aids (optional)
cargo install cargo-expand      # Macro expansion viewer
cargo install cargo-bloat       # Binary size analysis
cargo install cargo-mutants     # Mutation testing

# Nightly-only tools
cargo +nightly install cargo-udeps  # Unused dependencies (comprehensive)

5. Verify LSP Configuration

Check that .lsp.json exists and is properly configured:

cat .lsp.json

Expected configuration:

{
    "rust": {
        "command": "rust-analyzer",
        "args": [],
        "extensionToLanguage": {
            ".rs": "rust"
        },
        "transport": "stdio"
    }
}

6. Initialize deny.toml (if using cargo-deny)

If this project uses cargo deny, ensure deny.toml exists:

[ -f deny.toml ] || cargo deny init

7. Verify Hooks Configuration

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/rust-lsp (12 stars, last pushed 22d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 941 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
