Diagnose SQL database in Fabric performance via sqlcmd against Query Store, DMVs, sys.dm_db_resource_stats, and Extended Events on the OLTP endpoint. Identifies the top resource-consuming, slowest, or most expensive queries and handles query-performance ranking, blocking-chain, missing-index, and plan-regression diagnostics. For routine data queries use the sqldb-consumption-cli skill; for schema changes use the sqldb-authoring-cli skill. Triggers: "query store slow query analysis sqldb top queries", "top resource-consuming queries from query store sqldb", "slowest queries sql database in Fabric query store", "most expensive queries sqldb query store", "sql database in Fabric blocked sessions head blocker chain sqlcmd", "sqldb missing index recommendation", "sqldb regressed plan instability sqlcmd", "sqldb extended events trace".

Query SQL database in Fabric via sqlcmd: interactive exploration, vector similarity, JSON, temporal queries, and security policy inspection on the OLTP and SQL analytics endpoints.

Refactor cleanly instead of layering sediment. Use when a change reveals duplicated concepts, local adapters, obsolete owners, compatibility wrappers, parallel abstractions, an over-large module that has accreted many responsibilities, or "just tack this on" pressure in any code area.

Test file conventions: setup functions, factories, Result assertion helpers, organization, type testing, naming, and pruning low-value tests. Use when: "write tests", "add a test", "fix this test", "delete tests", "prune tests", "audit tests", or modifying *.test.ts files.

Per-change refactoring mechanics: count callers exactly, decide inline vs keep, collapse duplicate switch branches, route raw access through a single typed boundary, surgical one-change-per-commit, post-refactor straggler sweep for stale JSDoc and dead exports. Use when actually editing code to clean it up, when deciding whether a 1-caller helper earns its keep, or when planning a sequence of small refactor commits. For the smell catalog use code-audit; for session-long simplification use collapse-pass.

Use for authorized SQL injection testing with the sqlmap CLI, including detection, DBMS fingerprinting, request replay, and extraction checks against in-scope web targets.

Executes automated refactoring for specific files, directories, or semantic queries. This skill should be used when the user asks to refactor specific files or directories, simplify recently changed code, clean up dead code in a limited scope, or invokes "/refactor".

Use when asked to explain a SQL query, optimise slow SQL, translate SQL to plain English for non-technical stakeholders, write a query from a natural language description, or produce query documentation. Produces plain-English explanations, annotated optimised queries, or a data dictionary covering output shape, assumptions, and known limitations. Works across PostgreSQL, MySQL, BigQuery, Snowflake, and standard SQL.

Agent tracing CLI for execution snapshots. Use for agent-tracing, traces, snapshots, LLM call inspection, context engine data, agent step analysis, execution debugging, or pulling remote/production traces ("拉线上 tracing") by operation id. Also the first stop for debugging agent tool calls — wrong or missing tool_calls, unexpected tool arguments or results, which tools were available at a step, or why a tool ran where it did.

Reviews Home Assistant GitHub pull requests and provides feedback comments. This is the top skill to use for reviewing Pull Requests from GitHub.

Refactor user-facing UIStrings and localization comments in a DevTools module folder according to UX writing guidelines (child task of b/40799900).

USE FOR: write, create, review, or modernize MSTest tests and assertions, better MSTest assertion than Assert.IsTrue, replace hard cast with IsInstanceOfType, MSTest assertion APIs (Contains, ContainsSingle, HasCount, IsEmpty, IsNotEmpty, DoesNotContain, AreSame, IsNull, StartsWith, EndsWith, MatchesRegex, IsGreaterThan, IsLessThan, IsInRange), swapped/reversed Assert.AreEqual args (Expected/Actual backwards), replace ExpectedException with Assert.Throws, data-driven (DataRow, DynamicData, ValueTuples), lifecycle (TestInitialize, TestCleanup, TestContext), async and cancellation tests, conditional execution/retry/cleanup (OSCondition, Retry), parallelization (Parallelize/DoNotParallelize), MSTest.Sdk setup, MSTESTxxxx analyzer fixes. DO NOT USE FOR: test quality audits (use test-anti-patterns), running tests (use run-tests), MSTest version migration (use migrate-mstest skills), xUnit/NUnit/TUnit, or non-.NET languages.

Rewrite messy or AI-generated crawler code into clean, production-ready style that follows the zavod best practices. Use when the user asks to clean up, refactor, tidy, or "make production-ready" a crawler, or to bring code in line with best practices.

Static review rules for authorization, validation, and privilege escalation risks

HashQL testing strategies including compiletest (UI tests), unit tests, and snapshot tests. Use when writing tests for HashQL code, using //~ annotations, running --bless, debugging test failures, or choosing the right testing approach.

Builds production-quality, accessible, responsive user-facing UIs. Use when building or modifying interfaces and pages, creating components, implementing layouts, meeting WCAG accessibility requirements, managing state, or when the output needs to look and feel production-quality rather than AI-generated.

Build or extend LobeHub Agent Signal pipelines. Use for signal sources, signal/action types, policies, middleware, workflow handoff, dedupe, scope behavior, or observability.

Create and manage bb automations from the first-party automations plugin. Use when scheduling recurring or one-shot agent/script work with bb automation commands.

Gates whether a new test should exist and forces it to be efficient, protecting CI from low-value test bloat. Use before adding or substantially changing any pytest, Jest, or Playwright test — whenever an agent or engineer is about to write tests for a new feature, bugfix, or PR. Front-loads the value bar (every test must catch a realistic regression no existing test already catches; test behavior through the public interface, not implementation details; collapse near-duplicates into parameterized cases) and the efficiency bar (deterministic, isolated, fast; pick the cheapest test level; Django TestCase over TransactionTestCase; no sleeps, no real network). Includes a "don't write it" decision tree. For fixing an existing flaky test use `/fixing-flaky-tests`; after this gate says a Playwright test is warranted, use `/playwright-test` for mechanics.

Use when targeting Android/iOS — export and signing, permissions, plugins, in-app purchases, ads, app lifecycle, device features, and mobile performance

Direct browser control via CDP. Use when the user wants to automate, scrape, test, or interact with web pages. Connects to the user's already-running Chrome.

Refresh API compatibility baselines (CompatibilitySuppressions.xml) under Source/. Deletes existing suppression files, regenerates them via `dotnet pack -p:ApiCompatGenerateSuppressionFile=true`, then reviews the diff and flags any non-`LinqToDB.Internal.*` API changes for explicit user approval.

Security audit of a codebase — web apps, APIs, services, CLI tools, libraries, daemons, and more. Use when asked to find security bugs, do a security review, audit for vulnerabilities, or pen-test the code. Focuses on exploitable issues with real impact, not theoretical concerns or industry-standard behavior.

Enforce TypeScript strict mode and type safety. Use when setting up projects, reviewing code, or when type errors are ignored. Covers strict flags, no-any rules, and type inference best practices.

Auto-invoke when reviewing API routes, server logic, Express/Node.js code, or backend architecture. Enforces REST conventions, middleware patterns, and separation of concerns.

Produces a structured design specification (DESIGN.md + structural layout + Decision Trace) before any visual artifact is built — the "blueprint" phase that keeps AI-generated design from feeling templated. Use this skill whenever the user asks to design, plan, mock up, or restructure any visual output — PPT / slides / decks, landing pages, dashboards, posters, charts, infographics, marketing pages, UI components, prototypes, illustrations — even when they only say "make a slide about X" or "help me put together a page for Y". Also trigger on requests to critique or improve an existing design when the user wants a principled, spec-driven pass rather than just cosmetic tweaks. Do NOT trigger when the user has already handed you a completed DESIGN.md and only wants code implementation (defer to frontend-design or implement directly).
