rustfs

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.

Resolve failures from the repository's architecture guard scripts — check_layer_dependencies.sh, check_architecture_migration_rules.sh, check_unsafe_code_allowances.sh, check_logging_guardrails.sh, check_doc_paths.sh. Use when make pre-commit / pre-pr or CI fails on one of these checks.

Execute the Adversarial Validation policy from the root AGENTS.md — run the six reviewer roles (correctness, security, concurrency/durability, compatibility, performance, test coverage) with RustFS-specific attack probes. Use on every behavior-affecting code change, bug fix, or design proposal before declaring it done.

Invariants and change procedure for the target-plugin / extension system — plugin manifests, admin plugin/extension catalog and instance APIs, secret redaction, external-plugin install policy. Use when editing crates/targets (manifest, plugin, control_plane, catalog, runtime), crates/extension-schema, or rustfs/src/admin plugin_contract.rs / plugins_*.rs / extensions.rs / target_descriptor.rs.

Debug ILM tiering / lifecycle transition issues — NoSuchVersion on tier GET, restore failures, xl.meta inspection, remote-tier versionId tracing. Use when investigating tiered/transitioned objects, warm backends, or transition metadata.

Standardize and review RustFS logging with structured `tracing` events, lower noise on hot paths, preserve security-sensitive diagnostics, and extend guardrails to prevent legacy logging patterns from returning. Use when editing or reviewing RustFS logs, startup/config diagnostics, cloud metadata logs, request validation logs, or `scripts/check_logging_guardrails.sh`.

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.

Manages shadcn components and projects — adding, searching, fixing, debugging, styling, and composing UI, including chat interfaces. Provides project context, component docs, and usage examples. Applies when working with shadcn/ui, component registries, presets, --preset codes, or any project with a components.json file. Also triggers for "shadcn init", "create an app with --preset", or "switch to --preset".

Design and review RustFS Console interfaces with a consistent visual hierarchy, interaction model, responsive behavior, and operational safety. Use this skill whenever creating or changing Console pages, settings, forms, dialogs, tables, status views, destructive flows, mobile layouts, or UI screenshots—even when the request is described only as frontend implementation or visual polish.

Audit and fix UI quality issues across web apps, dashboards, landing pages, product sites, forms, dialogs, tables, component libraries, and rendered frontend flows. Use when the user asks for UI walkthrough, visual QA, pixel/detail review, dimensions, spacing, whitespace, color hierarchy, alignment, typography, icon sizing, theme switching checks, accessibility pass, design-system consistency, component migration follow-up, before/after screenshots, or broad frontend best-practice cleanup.
