Use this skill when you need a prioritized, risk-aware plan to improve tests from coverage results.
Define scope and baseline
Produce coverage snapshot
cargo llvm-cov (or cargo tarpaulin) with existing repo config.npm test -- --coverage and read coverage/coverage-final.json.pytest --cov=<pkg> --cov-report=json and read coverage.json.Rank highest-risk gaps
Propose high-impact tests

Publish a RustFS alpha/beta/stable release with an auditable flow: confirm target version and scope, update workspace and release assets (including strict rustfs.spec changelog identity/date/version format), run required verification, and finish with commit, push, and GitHub PR creation.
Apply RustFS security lessons distilled from repository GitHub Security Advisories. Use when making or reviewing RustFS code changes, doing security checks, handling PR review for auth/authz, IAM, storage, RPC, logging, CORS, console/browser, encryption, policy, or endpoint changes, and when deciding which security regression tests are required.
Prepare PR-ready diffs by validating scope, checking required verification steps, drafting a compliant English PR title/body, and surfacing blockers before opening or updating a pull request in RustFS.
Verify code changes by identifying correctness, regression, security, and performance risks from diffs or patches, then produce prioritized findings with file/line evidence and concrete fixes. Use when reviewing commits, PRs, and merged patches before/after release.
