cargo-check

cargo-check is a command for coding agents from olorehq/olore. It costs 0 tokens per session (6,045 once invoked), scanned A, original, MIT.

A Cargo command that checks a Rust package and its dependencies for compiler errors without completing the final code-generation step. Cargo is Rust’s build and package-management tool.

In plain words
What is it for?
Use it to check a package, selected packages, or a Rust workspace before running a full build.
Why use it?
It is usually faster than a full build when you only need to catch compilation problems. It can reuse compiler metadata from earlier checks.

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-check 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 5d 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.

NAME

cargo-check --- Check the current package

SYNOPSIS

cargo check [options]

DESCRIPTION

Check a local package and all of its dependencies for errors. This will essentially compile the packages without performing the final step of code generation, which is faster than running cargo build. The compiler will save metadata files to disk so that future runs will reuse them if the source has not been modified. Some diagnostics and errors are only emitted during code generation, so they inherently won't be reported with cargo check.

OPTIONS

Package Selection

By default, when no package selection options are given, the packages selected depend on the selected manifest file (based on the current working directory if --manifest-path is not given). If the manifest is the root of a workspace then the workspaces default members are selected, otherwise only the package defined by the manifest will be selected.

The default members of a workspace can be set explicitly with the workspace.default-members key in the root manifest. If this is not set, a virtual workspace will include all workspace members (equivalent to passing --workspace), and a non-virtual workspace will include only the root crate itself.

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.

cargo-check is a command published in the GitHub repository olorehq/olore (103 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 6,045 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
