Explore AI Agent Skills & Claude Prompts

A skill for performing code reviews and test quality checks as a QA engineer. Improves code coverage, detects test-faking code, catches swallowed exceptions, flags conditional logic in tests, promotes hardcoded assertions, and checks cross-platform/cross-runtime compatibility (Windows, Deno, Bun). Language- and framework-agnostic — works with any repository. Trigger this skill on keywords: code review, test, coverage, QA, quality check, test generation, refactoring, review, test, coverage, refactor. Always use this skill when the user requests a PR review or test improvement.

bench-triage

Triage one nu-only fixture from tests/external/snapshots/diff/nu-only.json by reading the spec, then drive its verdict to match-error, match-clean, or nu-over by either fixing markuplint or recording an excluded-ids.json entry. The core operation of the nu-validator coverage benchmark. Use when reducing the nu-only backlog, when checking a coverage-claim ("markuplint misses X" / "over-detects Y") against the bench, or when classifying a specific fixture. Trigger keywords: nu-only, ml-only, coverage gap, bench triage, verdict, match-error, match-clean, nu-over, excluded-ids, declare nu over-detection, claim audit, audit fixture, reduce nu-only, mark-up valid per spec, spec-cited exclusion.

migrate4-5

Guides you through migrating markuplint configuration from v4 to v5. Detects current versions, reviews the migration guide, interactively confirms breaking changes and new rules with the user, updates config files and tests. For Claude Code.

bench-rule-enable

Enable an existing or newly-added markuplint rule on the nu-validator bench by editing tests/external/bench/config.ts. Covers the flat-rule case (rules: { '<name>': true }) and the severity override case (rules: { '<name>': { severity: 'error' } }) that bench-virtual-rule does not. Use when a rule exists in the registry but the relevant nu fixtures stay nu-only because the rule is not enabled in the bench config, or when a rule's default severity is warning but the spec text it mirrors is a MUST / MUST NOT. Trigger keywords: enable bench rule, bench config flat rule, severity override bench, rule not flagging on bench, warning vs error in bench, escalate severity bench, wai-aria-implicit-props bench, bench coverage missing rule.

bench-setup

Set up the nu-validator benchmark environment — initialise the validator submodule, ensure Docker is running, populate the gitignored raw snapshots via yarn bench:update. Also covers Docker / nu-runner troubleshooting. Use when bench commands fail with "no snapshots found", "Docker daemon not reachable", port 28888 conflicts, or healthcheck timeouts; or when refreshing the bench after a long break. Trigger keywords: bench setup, bench Docker, validator submodule, no snapshots found, Docker daemon not reachable, healthcheck times out, port 28888, yarn bench:update first time, bench install, fresh clone bench.

bench-virtual-rule

Mirror a preset virtual rule (selectors under `nodeRules` in preset.html-standard.jsonc and similar) into bench/config.ts so the benchmark exercises it. Use when a new disallowed-element / similar selector lands in a preset and the matching nu fixtures remain stuck at nu-only despite the new rule existing in markuplint. Trigger keywords: virtual rule, nodeRules, disallowed-element, preset html-standard, bench config mirror, rule does not fire on bench, preset rule not exercised.

bench-xref

Sync benchmark cross-reference blocks onto GitHub Issue bodies via `yarn bench:xref`, manage `tests/external/bench/issue-xref.config.ts` mappings, and run the pre-release checklist. Use when adding / removing / updating a primary or secondary mapping, when an issue closes upstream, when the xref CLI's output disagrees with what's on the issue body, or before cutting a release that touches a rule the benchmark covers. Trigger keywords: bench-xref, issue-xref, xref CLI, GitHub issue body, primary mapping, secondary mapping, umbrella block, pre-release checklist, bench-xref-audit workflow, marker version.

product-manager

Analyze, review, and generate documentation for any repository from a Product Manager (PdM) perspective. Language- and framework-agnostic — works with any repository. Use this skill whenever you need to: understand repository structure, read and navigate code, analyze dependencies, generate or review READMEs and documentation, summarize the tech stack, evaluate architecture, assess operational impact of new features, or review PRs. Responds to requests like "what's going on in this repo?", "write a README", "review this change", "is this maintainable?", "what do you think of this PR?". If the task involves repository analysis, review, or documentation, use this skill without hesitation.

markuplint-setup

Set up Markuplint in a project from scratch. Detects framework, creates config, runs initial lint, and guides the user through rule adoption with Bulk Suppressions support.

markuplint-configure

Add, remove, or adjust Markuplint rules for specific files or elements. Analyzes violations, proposes scope-appropriate configuration changes, and confirms with the user.
