Build GraalVM native images using the native-maven-plugin (org.graalvm.buildtools). Use this skill to build Java applications with Maven, configure pom.xml native image settings, run native tests, collect metadata, or resolve build or runtime issues.

Migrate Terraform provider resources and data sources from Plugin SDKv2 to the Plugin Framework: muxing both plugins in one provider (terraform-plugin-mux, tf5to6server), per-resource migration workflow, SDKv2-to-Framework schema mapping (ForceNew, ValidateFunc, DiffSuppressFunc, Default, Timeouts, blocks), null-vs-zero-value behavioral traps, and state-compatibility verification. Use when converting or translating SDKv2 resources to the Framework, setting up a muxed provider server, deciding whether a resource should be migrated at all, or debugging plan diffs and state errors that appeared after a migration.

Create a new Mattermost plugin from the starter template in the current directory. Use when creating a new plugin from scratch, scaffolding a Mattermost plugin, or bootstrapping a plugin project.

Generate custom favicons from logos, text, or brand colours. Produces favicon.svg, favicon.ico, apple-touch-icon.png, icon-192/512.png, and web manifest. Use whenever the user wants a favicon, mentions replacing a CMS default favicon, converting a logo into a favicon, creating branded initials icons, or troubleshooting favicon not displaying / iOS black square / missing manifest.

Use when writing a Vitest test for a react-router useBlocker unsaved-changes guard in this repo — specifically an intentional-navigation handler (Edit / Submit / Cancel) that uses flushSync(() => setIsNavigating(true)) before navigate() to bypass the blocker. A test that reads the blocker predicate after act() passes even when flushSync is removed, so it does not guard the fix. Trigger on any test touching isNavigating, useBlocker, flushSync, or a *.hooks.js navigation-blocker handler.

Run, monitor, and fix frontend Cypress E2E tests. Handles local execution, CI monitoring, failure diagnosis, flaky test detection, and accessibility regression checks. Use this skill whenever the user mentions Cypress, E2E tests, end-to-end tests, test failures, CI failures, "CI is red", flaky tests, accessibility testing, or wants to run/debug/fix any frontend integration test — even if they don't say "e2e" explicitly.

Guide for porting CDS React Native components to Jetpack Compose in packages/cds-android, and for auditing existing Android ports for completeness and quality. USE THIS whenever the user asks to port, migrate, or bring a CDS mobile/RN component to Android/Compose/Kotlin, audit an Android CDS component against mobile parity, or review whether a cds-android port is done correctly. Also trigger for phrases like "RN to Compose", "mobile to Android CDS", "port Button/Chip/Card to cds-android", "public API boundary", or "does our Android Button match mobile". Loads the CDS Compose Best Practices document from Linear, which is the source of truth for porting rules and learnings. Load jetpack-best-practices alongside this skill for Compose API shape.

Deprecates a CDS component, hook, or other exported symbol with consistent JSDoc, version tags, and docsite metadata across every public export path (web, mobile, common, visualization), not only the original package. Use whenever the user asks to deprecate a CDS component or API, mark something as deprecated, add @deprecated / @deprecationExpectedRemoval, or update deprecation warnings in apps/docs metadata under components or hooks (webMetadata.json / mobileMetadata.json / metadata.json). Also use when replacing a component or hook and sunsetting the old one. Always finish by running `yarn nx run <project>:lint` on modified packages so `internal/deprecated-jsdoc-has-removal-version` passes.

Search, read, draft, create, or update Confluence Cloud wiki pages. Use for titles, sections, spaces, and child pages; use jira for Jira issues.

Methodology for clause-by-clause review of a contract against a structured deviation policy ("playbook"). Covers how to walk a playbook, locate the matching provision in the contract, apply rule types (max-value, must-be-present, must-be-absent, acceptable-set, must-have-feature), classify the result (ok / risk / reject), choose the prescribed action, and ground each finding in a verbatim excerpt. Use whenever reviewing any contract — NDA, MSA, vendor DD questionnaire, lease, DPA — against a structured rules-based playbook.

Guide for building Apple-platform applications with Apollo iOS, the strongly-typed GraphQL client for Swift. Use this skill when: (1) adding Apollo iOS to a Swift Package Manager or Xcode project, (2) configuring `apollo-codegen-config.json` and running code generation, (3) configuring an `ApolloClient` with auth, interceptors, and caching, (4) writing queries, mutations, or subscriptions from SwiftUI views, (5) writing tests against generated operation mocks.

Generate and analyze AI Bill of Materials (AIBOM) for Python projects using AI/ML components. Identifies AI models, datasets, tools, and frameworks for security and compliance tracking. Use this skill when: - User asks to scan for AI components - User wants to know what AI models a project uses - User mentions "AI BOM", "AI inventory", or "ML security" - User is working with Python AI/ML projects (PyTorch, TensorFlow, HuggingFace) - User needs AI component compliance documentation

Manages Mixpanel credentials for the mixpanel_headless library and the mp CLI — checks the active session, lists, adds, and switches accounts, runs OAuth login (one-shot `mp login` or the two-step flow), switches projects and workspaces, and manages saved targets. Use when Mixpanel credentials are missing or failing, when code raises AuthenticationError or reports no account or no project, when the user wants to log in, switch account, project, or workspace, or save or use a target; on 401 or "unauthorized" errors; for "which project am I on?"; or for a login in the EU or India region. Do not use for installing or upgrading the library (use setup) or for analytics questions once credentials work (use mixpanelyst).

Performs quality control on single-cell RNA-seq data (.h5ad or .h5 files) using scverse best practices with MAD-based filtering and comprehensive visualizations. Use when users request QC analysis, filtering low-quality cells, assessing data quality, or following scverse/scanpy best practices for single-cell analysis.

Deep learning for single-cell analysis using scvi-tools. This skill should be used when users need (1) data integration and batch correction with scVI/scANVI, (2) ATAC-seq analysis with PeakVI, (3) CITE-seq multi-modal analysis with totalVI, (4) multiome RNA+ATAC analysis with MultiVI, (5) spatial transcriptomics deconvolution with DestVI, (6) label transfer and reference mapping with scANVI/scArches, (7) RNA velocity with veloVI, or (8) any deep learning-based single-cell method. Triggers include mentions of scVI, scANVI, totalVI, PeakVI, MultiVI, DestVI, veloVI, sysVI, scArches, variational autoencoder, VAE, batch correction, data integration, multi-modal, CITE-seq, multiome, reference mapping, latent space.

Create, place, preview, debug, and connect manifest-backed IWSDK UIKitML assets. Use for spatial panels, browser HUDs, UIKitML layout, fonts, editor previews, or runtime element behavior.

Audit an existing product surface against its own design evidence, identify verified UI problems, and write self-contained implementation plans for another agent. Strictly read-only on product source. Use when asked to review, refine, improve, or clean up an interface without replacing its identity; investigate design-system drift; or prepare a design handoff.

Search and retrieve content from Product Hunt. Get posts, topics, users, and collections via the GraphQL API. Use when user mentions Product Hunt, PH, or product launches.

Fuzz React Doctor rules for crashes, slowness, false positives, and mutation-sensitive diagnostics with @react-doctor/fuzz. Use after rule tests pass, when investigating a fuzz finding, or whenever an eval, review, or user report confirms a new false positive.

Send and receive WhatsApp messages via the unofficial linked-device client pywhats (pip install pywhats) — pair with QR, send text/images, group chat, read receipts, presence/typing, and a long-running JSON event stream. Use when the user wants to script WhatsApp as a linked companion device (like WhatsApp Web), pair a device, send a WhatsApp from Python, or listen for inbound messages. Triggers: 'whatsapp', 'send whatsapp', 'pair whatsapp', 'pywhats', 'linked device', 'whatsapp web client'. NOT the official WhatsApp Business/Cloud API.
