grafema: Skill for Claude Code

.claude/skills/rust-cargo-fast-iteration-profile/SKILL.md

rust-cargo-fast-iteration-profile is a skill for Claude Code from Disentinel/grafema. It costs 216 tokens per session (1,868 once invoked), scanned A, original, no licence file.

A Rust development guide for making release-like builds faster during repeated development. Rust is a programming language, and Cargo is its build tool.

In plain words
What is it for?
Use it when release builds are slow after small edits, especially when Cargo.toml enables fat link-time optimisation or only one code-generation unit.
Why use it?
It addresses cases where tiny Rust changes trigger release builds that take many minutes, often because of costly optimisation settings.

This is Disentinel/grafema's own configuration. It tells Claude Code how to work on grafema 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 grafema 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-cargo-fast-iteration-profile 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 11d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

→ curl test → repeat`, and the build dominates wall-clock.

The source is not reproduced here

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.
