Maintain @next/rspack-core and @next/rspack-binding packages. Use when editing rspack/package.json, rspack/crates/binding/Cargo.toml, rspack/rust-toolchain.toml, or packages/next-rspack/package.json. Covers upgrading @rspack/core npm version, rspack_* crate versions, Rust toolchain version, building and linking for local testing, and NEXT_RSPACK environment variable usage. Does NOT apply to root rust-toolchain.toml (that's for Turbopack).
Worker-Agent integration for intelligent task dispatch and performance tracking
Patterns for FluentUI React v9 components in VS Code webviews. Use when working with any FluentUI component (Toolbar, Overflow, Menu, Button, Dialog, etc.), debugging layout or styling issues with FluentUI, implementing toolbar overflow (collapsing items into a "..." menu), or integrating FluentUI components in webview panels.
Generate developer handoff specs from a design. Use when a design is ready for engineering and needs a spec sheet covering layout, design tokens, component props, interaction states, responsive breakpoints, edge cases, and animation details.
Write or audit an insight-kind error page for the Next.js dev overlay. Use when creating a new `errors/<slug>.mdx` page, auditing an existing one, or checking that a page matches the framework fix cards. Covers page structure, title alignment, FixCard cards with Copy prompt button, code snippets, terminology verification against canonical docs, and Vercel technical writing style.
Run comprehensive worker system benchmarks and performance analysis
How infrastructure-caused database failures are turned into messages users can act on, via ConnectionDiagnosticsService. Use when adding a discovery plugin, a connection source, a reachability provider, a new tree view or webview surface, when a user reports a confusing or raw driver error, or when asked to improve error messages for Docker, Kubernetes, Atlas, Azure or any other infrastructure-backed connection.
Get structured design feedback on usability, hierarchy, and consistency. Trigger with "review this design", "critique this mockup", "what do you think of this screen?", or when sharing a Figma link or screenshot for feedback at any stage from exploration to final polish.
Manages stacked PRs and splits multi-part work into reviewable branches with gh-stack. Use for stack creation, viewing, edits, push, submit, sync, rebase, merge, or checkout; when asked to split or isolate work for review; whenever a user mentions a stack, branch layers, dependent PRs, or gh stack; or when a stack is checked out.
Comprehensive truth scoring, code quality verification, and automatic rollback system with 0.95 accuracy threshold for ensuring high-quality agent outputs and codebase reliability.
Backport changes (the current branch, a PR, another branch, or specific commits/SHAs) onto a target branch — typically a short-lived release branch such as `release/0.10.1`. Use when the user says "backport this", "backport PR
Run a WCAG 2.1 AA accessibility audit on a design or page. Trigger with "audit accessibility", "check a11y", "is this accessible?", or when reviewing a design for color contrast, keyboard navigation, touch target size, or screen reader behavior before handoff.
How to use the `@gate` / `@force-gate` test directives instead of `it.skip` or fake-green skip patterns. Use when a test is known-failing under some test-matrix dimension (dev mode, a bundler, an experimental flag like cacheComponents), when converting `if (isNextDev) return` guards or env-var `describe.skip` branches, when adding a condition to test/lib/gate/conditions.ts, or when keying a fixture's experimental flag on a __NEXT_TEST_AXIS letter. Covers directive choice, condition tiers, the test-axis fixture pattern, pitfalls, and verification commands.
15-agent hierarchical mesh coordination for v3 implementation. Orchestrates parallel execution across security, core, and integration domains following 10 ADRs with 14-week timeline.
Detects and fixes accessibility issues in React/Fluent UI webviews. Use when reviewing code for screen reader compatibility, fixing ARIA labels, ensuring keyboard navigation, adding live regions for status messages, or managing focus in dialogs.
Write optimized SQL for your dialect with best practices. Use when translating a natural-language data need into SQL, building a multi-CTE query with joins and aggregations, optimizing a query against a large partitioned table, or getting dialect-specific syntax for Snowflake, BigQuery, Postgres, etc.
How to add or modify Next.js experimental feature flags end-to-end. Use when editing config-shared.ts, config-schema.ts, define-env-plugin.ts, next-server.ts, export/worker.ts, or module.compiled.js. Covers type declaration, zod schema, build-time injection, runtime env plumbing, and the decision between runtime env-var branching vs separate bundle variants.
Complete security architecture overhaul for claude-flow v3. Addresses critical CVEs (CVE-1, CVE-2, CVE-3) and implements secure-by-default patterns. Use for security-first v3 implementation.
Generate, explain, edit, and fix Azure Cosmos DB for NoSQL (SQL API) queries. Use whenever you need to produce a syntactically correct, safe Cosmos DB NoSQL query — for example when the user asks to generate, write, edit, fix, or explain a Cosmos DB NoSQL query. Provides the NoSQL dialect rules, safety rules, and few-shot examples. Covers SELECT/VALUE/DISTINCT/TOP, array-unwind JOINs, subqueries, WHERE/BETWEEN/IN/LIKE, GROUP BY and aggregates, ORDER BY and ORDER BY RANK, OFFSET/LIMIT, the full built-in function reference, and how Cosmos DB NoSQL differs from T-SQL / PostgreSQL / MySQL.
QA an analysis before sharing -- methodology, accuracy, and bias checks. Use when reviewing an analysis before a stakeholder presentation, spot-checking calculations and aggregation logic, verifying a SQL query's results look right, or assessing whether conclusions are actually supported by the data.
Validate a commit-specific Next.js preview package and manually trigger the entire Next.js deployment test suite through the test_e2e_deploy_release.yml GitHub Actions workflow. Use only when asked to run the full deploy test suite or this workflow specifically from an internal vercel/next.js PR branch. Do not use for focused deployment-test sanity checks; run the relevant tests locally with pnpm test-deploy instead. Covers resolving the latest branch SHA, waiting for vercel-packages, preserving default workflow inputs, dispatching the workflow, and verifying the run.
Achieve aggressive v3 performance targets: 2.49x-7.47x Flash Attention speedup, 150x-12,500x search improvements, 50-75% memory reduction. Comprehensive benchmarking and optimization suite.
Drive the active Azure Cosmos DB for NoSQL Query Editor in VS Code from natural language. Use whenever the user asks in natural language to show / find / list / count / filter data "in this container", "in my container", or in the active Cosmos DB Query Editor (for example: "show me all trucks in this container", "find active users", "count documents by type"), or to generate, edit, or explain a query for the active editor. This skill orchestrates the VS Code Language Model tools that read editor context, sample the container schema, apply a query, and run it; it delegates all Cosmos DB NoSQL
Apply statistical methods including descriptive stats, trend analysis, outlier detection, and hypothesis testing. Use when analyzing distributions, testing for significance, detecting anomalies, computing correlations, or interpreting statistical results.
