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 | $0.00048 | $0.00273 |
| Opus 5.5 | $0.00019 | $0.00109 |
| Sonnet 5.5 | $0.00010 | $0.00055 |
| Haiku 4.5 | $0.00005 | $0.00027 |
Grade A, and why
cli 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 1mo 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.
What it actually says
Rust CLI Applications
Argument parsing, user-facing output, exit codes, signal handling, and subprocess testing for command-line tools.
For argument parsing, error context, output, signals, exit codes, and testing patterns, see references/cli.md.
Example
use clap::Parser;
#[derive(Parser)]
struct Cli {
pattern: String,
path: std::path::PathBuf,
}
fn main() {
let cli = Cli::parse(); // derives parsing, validation, and --help
}
The full argument-parsing, error-context, output, signals, exit-code, and testing patterns are in references/cli.md.
This skill covers CLI-specific ecosystem crates. For custom error enum design (thiserror) shared with non-CLI code, see rust:error-handling. For unit and integration test structure not specific to CLI binaries, see rust:testing.
See /core:anti-fabrication — crate versions and behavior claims in this skill are verified against crates.io and the upstream Rust CLI Book, not assumed.
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.

cli is a skill published in the GitHub repository vinnie357/claude-skills (27 stars, last pushed 12d ago), licensed MIT. It adds 48 tokens to every session and 273 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
