What is husk AGENTS.md?

Repository-specific instructions for developing husk, a local Rust security scanner with command-line, terminal-interface, web, daemon, and project-management features.

Use them when working on husk to install the right Rust, Node.js, and hygiene tools and follow the project’s development and CI requirements.

They explain the repository layout, required software, optional features, and checks needed to build and validate changes correctly.

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	$0.05584	$0.05584
Opus 5.5	$0.02234	$0.02234
Sonnet 5.5	$0.01117	$0.01117
Haiku 4.5	$0.00558	$0.00558

Security

Grade A, and why

husk AGENTS.md scanned grade A 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 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.

Unrestricted tool accesslowExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

- Run any command in this document against the pinned toolchain by prefixing it: `nix develop -c cargo build --no-default-features`

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 365 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This repo

This repository contains the open-source husk CLI: a local-first Rust security scanner for developer machines. It ships one binary with the command-line interface, Ratatui TUI, optional localhost web UI, daemon, project policy/ledger commands, and MCP server.

The hosted website and any backend service code are not in this repository. The client-side cloud integrations here are optional and inert until a user signs in or explicitly enables telemetry.

What you need installed

Rust 1.95 or newer, with Cargo, plus rustfmt and clippy. CI pins 1.95.0. Building on Linux also wants a C toolchain; CI installs build-essential, pkg-config, and libssl-dev.
Node 24 (CI pins 24.16.0), needed only for the default web feature, which embeds the localhost web UI. --no-default-features needs no Node.
The hygiene tools CI runs, if you want to reproduce that gate locally:
```
cargo install cargo-deny cargo-machete typos-cli taplo-cli
```
These four are what deps + repo hygiene runs in CI. cargo-nextest is optional and unrelated; it is a faster test runner.

There is no Nix requirement anywhere. CI itself uses a plain Rust toolchain and plain cargo.

Development commands

Build the Rust crate quickly: cargo build --no-default-features
Run tests: cargo test --no-default-features
Run faster test loops: cargo nextest run --no-default-features
Run clippy strictly: cargo clippy --no-default-features --all-targets -- -D warnings
Format Rust: cargo fmt
Run the fixture scan: cargo run --no-default-features -- scan --offline tst --no-home-inventory
Run the fixture web UI without opening a browser: npm --prefix web ci && npm --prefix web run build, then cargo run -- web --offline --no-open tst --no-home-inventory
Run CI JSON mode: cargo run --no-default-features -- ci --offline tst --no-home-inventory

Prefer cargo run -- ... over invoking a binary in target/ directly, so you never test a stale build.

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.

husk AGENTS.md is an instructions file published in the GitHub repository husk-security/husk (6 stars, last pushed yesterday), licensed MIT. It adds 5,584 tokens to every session, about $0.0223 per session on Opus 5.5. A static security scan graded it A with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
