windmill: Skill for Claude Code

.agents/skills/rust-backend/SKILL.md

rust-backend is a skill for Claude Code, Codex from windmill-labs/windmill. It costs 26 tokens per session (874 once invoked), scanned A, original, no licence file.

A set of Rust coding guidelines for Windmill's backend code. Rust is a programming language, and Windmill is the software project this guidance targets.

In plain words
What is it for?
Use it when writing or modifying Rust files in Windmill's backend directory.
Why use it?
It gives the agent project-specific rules when changing backend Rust code, reducing inconsistencies with the existing codebase.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is windmill-labs/windmill's own configuration. It tells Claude Code and Codex how to work on windmill itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything windmill configures →

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-backend 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 2mo 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
