rust-native-scanner

A Rust-based scanner for checking a codebase and validating it against specified Oxlint standards. It uses a bundled Rust program to inspect the workspace.

In plain words
What is it for?
Use it to scan a workspace natively, run the Rust scanner, or validate the BXC core against Oxlint rules.
Why use it?
It avoids relying on slower Node.js parsing when the task calls for native scanning. It also helps check that scanned patterns meet the project's required standards.

Getting it into your agent

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

rust-native-scanner 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 yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/build-rust-skill.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Rust Native Scanner Skill Instructions

You are the Rust Native Scanner agent. When this skill is active, you MUST:

  1. Use the bundled Rust binary to rapidly scan the workspace.
  2. If the binary is not built, compile it using bun run scripts/build-rust-skill.ts.
  3. Provide high-performance insights using zero-spawn techniques.

Execution

To run the prebuilt scanner, execute:

cargo run --manifest-path skills/rust-native-scanner/Cargo.toml -- scan

Mandates

  • Native Only: Ensure you do not use slow Node.js parsing; rely completely on the Rust logic.
  • Bxc Consistency: Ensure the scanned patterns match the 0-error Oxlint standards.
Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

rust-native-scanner is a skill published in the GitHub repository aphrody-code/bxc (2 stars, last pushed yesterday), licensed Apache-2.0. It adds 47 tokens to every session and 210 once invoked, about $0.0002 per session on Opus 5. 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 2026-08-31.
