cargo-coupling: Skill for Claude Code

.agents/skills/release/SKILL.md

release is a skill for Claude Code from nwiizo/cargo-coupling. It costs 34 tokens per session (429 once invoked), scanned B, original, MIT.

A release checklist and workflow for a Rust project. It covers formatting, linting, tests, release builds, version updates, commits, and tags; Rust is a programming language, and Cargo is its build and package tool.

In plain words
What is it for?
Use it to prepare and publish Rust releases, including updating Cargo.toml and Cargo.lock.
Why use it?
It helps catch formatting, compiler, lint, and test problems before publishing a new version. It also makes the version-control steps repeatable.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is nwiizo/cargo-coupling's own configuration. It tells Claude Code how to work on cargo-coupling 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 cargo-coupling 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 B, and why

release scanned grade B 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 20d 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.

What it actually says

Release cargo-coupling

Match the requested version and publication scope. A preparation request ends with verified local artifacts; a publish request includes the authorized release commit, tag, push, and publication verification. Carry existing authorization forward. Resolve a missing version before changing release metadata; meanwhile inspect the branch, remote, status, and current release workflow.

Update Cargo.toml and refresh Cargo.lock without upgrading unrelated dependencies. Run the required checks against the final release state:

rtk cargo fmt --all -- --check
rtk cargo clippy --locked --all-targets --all-features -- -D warnings
rtk cargo test --locked --all-features
rtk cargo build --locked --release

Before publication, verify the staged diff, intended branch and remote, matching manifest/lockfile versions, and that the tag does not already identify a different release. Preserve unrelated work. Use an annotated vX.Y.Z tag on the verified release commit; the commit message is chore: release vX.Y.Z. Push only the intended branch and tag to the verified remote; never replace an existing release tag.

Pushing a v* tag triggers .github/workflows/release.yml, which publishes to crates.io and creates a GitHub release. Check both outcomes before reporting publication complete. If publication fails or is uncertain, inspect the workflow and registry state before retrying; do not create another version or move a tag to bypass the failure.

The optional Claude hook in .claude/settings.json checks formatting and lint for matching commit commands. It does not establish that all release checks ran in another host. Reuse successful current checks while the release state is unchanged.

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.

release is a skill published in the GitHub repository nwiizo/cargo-coupling (116 stars, last pushed 2d ago), licensed MIT. It adds 34 tokens to every session and 429 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
