Gold-Band: Skill for Claude Code

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

rust-profiling is a skill for Claude Code, Codex from diodeme/Gold-Band. It costs 86 tokens per session (1,749 once invoked), scanned B, original, AGPL-3.0.

A Rust performance-analysis guide for examining where programs spend time, how large binaries become, and how benchmarks behave. Rust is a programming language; flamegraphs show time spent in call stacks, while tools such as cargo-bloat inspect binary size.

In plain words
What is it for?
Use it for Rust flamegraphs, monomorphization-size analysis, binary-size analysis, Criterion microbenchmarks, and interpreting inlined stack frames.
Why use it?
It helps locate slow code, large compiled components, excessive generated code, and misleading or difficult-to-read profile results.

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 diodeme/Gold-Band's own configuration. It tells Claude Code and Codex how to work on Gold-Band 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 Gold-Band 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 B, and why

rust-profiling 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 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.

Asks for rootmediumPrivilege escalation

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

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.
