cargo-yank

cargo-yank is a command for Claude Code from olorehq/olore. It costs 0 tokens per session (2,876 once invoked), scanned A, original, MIT.

A Cargo command that marks a published Rust package version as yanked in the package index. Yanking stops new projects from choosing that version, but does not delete it or break projects already using a lock file.

In plain words
What is it for?
Use it to withdraw a published crate version from normal dependency selection after an issue is found.
Why use it?
It helps prevent new users from selecting a package version with a serious problem while preserving downloads and existing locked builds.

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

cargo-yank 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 8d 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.

NAME

cargo-yank --- Remove a pushed crate from the index

SYNOPSIS

cargo yank [options] crate@version
cargo yank [options] --version version [crate]

DESCRIPTION

The yank command removes a previously published crate's version from the server's index. This command does not delete any data, and the crate will still be available for download via the registry's download link.

Cargo will not use a yanked version for any new project or checkout without a pre-existing lockfile, and will generate an error if there are no longer any compatible versions for your crate.

This command requires you to be authenticated with either the --token option or using cargo-login(1).

If the crate name is not specified, it will use the package name from the current directory.

How yank works

For example, the foo crate published version 1.5.0 and another crate bar declared a dependency on version foo = "1.5". Now foo releases a new, but not semver compatible, version 2.0.0, and finds a critical issue with 1.5.0. If 1.5.0 is yanked, no new project or checkout without an existing lockfile will be able to use crate bar as it relies on 1.5.

In this case, the maintainers of foo should first publish a semver compatible version such as 1.5.1 prior to yanking 1.5.0 so that bar and all projects that depend on bar will continue to work.

As another example, consider a crate bar with published versions 1.5.0, 1.5.1, 1.5.2, 2.0.0 and 3.0.0. The following table identifies the versions cargo could use in the absence of a lockfile for different SemVer requirements, following a given release being yanked:

Yanked Version / SemVer requirement bar = "1.5.0" bar = "=1.5.0" bar = "2.0.0"
1.5.0 Use either 1.5.1 or 1.5.2 Return Error Use 2.0.0
1.5.1 Use either 1.5.0 or 1.5.2 Use 1.5.0 Use 2.0.0
2.0.0 Use either 1.5.0, 1.5.1 or 1.5.2 Use 1.5.0 Return Error
