Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00098 | $0.01702 |
| Opus 5 | $0.00049 | $0.00851 |
| Sonnet 5 | $0.00020 | $0.00340 |
| Haiku 4.5 | $0.00010 | $0.00170 |
Grade A, and why
rust-cross 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Rust Cross-Compilation
Purpose
Guide agents through Rust cross-compilation: adding rustup targets, using cross for hermetic Docker-based cross-builds, cargo-zigbuild for zero-setup cross-compilation, .cargo/config.toml configuration, and embedded bare-metal targets.
Triggers
- "How do I cross-compile Rust for ARM/aarch64?"
- "How do I build a Rust binary for a different OS?"
- "How do I use the cross tool for Rust cross-compilation?"
- "How do I build Rust for embedded (no_std) targets?"
- "How do I use cargo-zigbuild?"
- "My cross-compiled Rust binary won't run on the target"
Workflow
1. Add a rustup target
# List installed targets
rustup target list --installed
# List all available targets
rustup target list
# Add a target
rustup target add aarch64-unknown-linux-gnu
rustup target add x86_64-unknown-linux-musl # static Linux
rustup target add wasm32-unknown-unknown # WASM
rustup target add thumbv7m-none-eabi # Cortex-M
# Build for target
cargo build --target aarch64-unknown-linux-gnu --release
2. Common target triples
| Target | Use case |
|---|---|
x86_64-unknown-linux-gnu |
Linux x86-64 (glibc) |
x86_64-unknown-linux-musl |
Linux x86-64 (musl, static) |
aarch64-unknown-linux-gnu |
ARM64 Linux (Raspberry Pi 4, AWS Graviton) |
aarch64-unknown-linux-musl |
ARM64 Linux static |
x86_64-pc-windows-gnu |
Windows x86-64 (MinGW) |
x86_64-pc-windows-msvc |
Windows x86-64 (MSVC) |
x86_64-apple-darwin |
macOS x86-64 |
aarch64-apple-darwin |
macOS Apple Silicon |
wasm32-unknown-unknown |
WASM (browser) |
wasm32-wasi |
WASM with WASI |
thumbv7m-none-eabi |
Cortex-M3 bare metal |
thumbv7em-none-eabihf |
Cortex-M4/M7 with FPU |
riscv32imac-unknown-none-elf |
RISC-V 32-bit bare metal |
3. cross tool (Docker-based, easiest)
cross uses pre-built Docker images with the correct cross-toolchain:
# Install
cargo install cross
# Build (drop-in replacement for cargo)
cross build --target aarch64-unknown-linux-gnu --release
cross test --target aarch64-unknown-linux-gnu
# Cross.toml — project configuration
What ships with it
1 file 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.
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-cross is a skill published in the GitHub repository mohitmishra786/low-level-dev-skills (203 stars, last pushed 2mo ago), licensed MIT. It adds 98 tokens to every session and 1,702 once invoked, about $0.0005 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 2026-09-03.
