io.github.ruvnet/ruflo/adr-review

Review code changes against accepted ADRs for compliance violations

io.github.ruvnet/ruflo/git-workflow

Advanced git workflows with branch management, conflict resolution, and PR lifecycle

io.github.ruvnet/ruflo/security-scan

Run full security scans on the codebase using Ruflo security tools. Use when reviewing PRs for security regressions, auditing auth/input-handling code, before production deploys, or when the user asks for a security check at quick/standard/deep depth.

io.github.ruvnet/ruflo/api-docs

Generate API documentation from source code with JSDoc and OpenAPI support

io.github.anthropics/skills/xlsx

Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .xltx, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.

io.github.nrwl/nx/reproduce-issue

The single skill for reproducing an nx issue. Given a GitHub issue number (human entry) OR explicit repro parameters (agent entry), it runs the reproduction ENTIRELY inside an isolated Docker sandbox — gVisor on Linux, the Docker VM on macOS — so the untrusted repro's install scripts and commands never execute on the host, then reports whether it reproduces. Called by humans via "/reproduce-issue

io.github.nrwl/nx/review-pr

Deep code review of a single open PR in nrwl/nx. Sets up an isolated worktree, runs the pr-review-toolkit review agents, the reproduce-verifier agent (grounds the review in the linked issues and, when runnable locally, executes the repro on master vs PR), the alternative-approach agent (independently designs competing solutions and contrasts them with the PR's choice), the performance-analyzer agent (checks the changes don't waste CPU or memory and execute quickly at workspace scale), and the security-analyzer agent (hunts injection-class vulnerabilities — command injection, zip-slip, SSRF, credential leakage — across real trust boundaries), surfaces only critical and important findings (plus strengths; nice-to-have suggestions are dropped), and saves a GitHub-flavored draft to ~/.nx-pr-reviews/<NUMBER>.md for the reviewer to read (nothing is posted). Use when you want a thorough review of one PR.

io.github.BuilderIO/agent-native/design-systems

Manage and apply Design app brand systems. Use when creating, importing, linking, inspecting, or following design-system tokens, assets, fonts, logos, and custom instructions.

io.github.BuilderIO/agent-native/design-generation

Generate or refine complete interactive HTML prototypes in Design. Use when creating screens, variants, Alpine/Tailwind prototypes, tweaks, or visual refinements from a prompt or selected design.

io.github.Arize-ai/phoenix/phoenix-design

Design system conventions for the Phoenix frontend — layout, dialogs, error display, BEM CSS class naming, and CSS design tokens. Use when building UI, naming CSS classes, creating or consuming tokens, handling errors, or designing dialog interactions in app/src/.

io.github.ethereum/ethereum-org-website/design-system

Use when building, refactoring, or styling any UI in the ethereum.org Next.js site (`src/components/`, `app/`, `src/styles/`, `public/content/`, or any `.tsx`/`.mdx`/`.css` change that affects the rendered UI). Provides canonical component choices, design tokens, RTL/i18n rules, server/client guidance, and the "use a variant, not a new component" pattern for the project's Tailwind v4 + Radix + shadcn-style design system.

io.github.dotnet/maui/code-review

Deep code review of PR changes for correctness, safety, and MAUI conventions. Uses independence-first assessment (code before narrative) and delegates to the maui-expert-reviewer agent for per-dimension sub-agent evaluation. Triggers on: "review code for PR", "code review PR", "analyze code changes", "check PR code quality". Do NOT use for: summarizing PRs, describing what changed, general PR questions, running tests, or fixing code.

io.github.flutter/agent-plugins/api-review

Reviews the specified code against the canonical API Design guidelines. Use this skill when the user asks for an API review or to check code against API design principles.

io.github.microsoft/fast/testing

Use this skill when running or writing tests in the FAST monorepo — local test execution, CI workflows, Playwright fixtures, and WebUI integration testing.

io.github.PostHog/posthog/running-ci-preflight

Catch the deterministic CI failures reachable from your diff before pushing, with `hogli ci:preflight`. Use when the pre-push hook blocks a push, before reporting a task done, or after editing Python, serializers, migrations, workflows, or dependency manifests — to avoid burning a CI matrix on a failure you could catch locally (formatting, lint, broken lockfiles, OpenAPI drift, migration conflict, stale branch). Trigger terms: ci:preflight, preflight, pre-push checks, pre-push hook failed, "will this break CI".

io.github.PostHog/posthog/writing-kea-logics

Guide for writing or reviewing PostHog kea logic files (`*Logic.ts` / `*Logic.tsx`). Use when creating a new logic, adding actions/reducers/selectors/listeners/loaders/forms/router bindings, choosing between reducer vs selector vs cache, deciding between listeners and `kea-subscriptions`, wiring React with `useValues`/`useActions`/`BindLogic`, or onboarding to kea conventions. Read keajs.org for upstream API; this skill captures PostHog-specific conventions and idioms.

io.github.BuilderIO/agent-native/design-templates

Find, save, copy, and adapt Design templates. Use when the user references a template, a prior design, or wants a reusable starting point.

io.github.TanStack/table/api-not-found

Diagnose missing TanStack Table v9 exports, options, state slices, and instance methods. Load before inventing an API when code sees a type error, undefined feature method, absent object key, adapter mismatch, or v8-shaped example.

io.github.TanStack/table/typescript

Preserve TanStack Table v9 inference with createColumnHelper, columns(), tableOptions, tableFeatures, and metaHelper. Load for ColumnDef errors, reusable tables, typed meta, named registries, or unnecessary manual feature generics.

skillsmp.droidrun-mobilerun-skill-md

Mobilerun documentation reference. Use when users ask about Mobilerun setup, configuration, SDK usage, CLI commands, device setup, agents, architecture, app cards, credentials, tracing, Docker, migration, structured output, or any Mobilerun "how do I..." questions.

io.github.mastra-ai/mastra/react-best-practices

React performance optimization guidelines from Mastra Engineering. This skill should be used when writing, reviewing, or refactoring React code to ensure optimal performance patterns. Triggers on tasks involving React components, data fetching, bundle optimization, or performance improvements.

io.github.PostHog/posthog/setting-up-a-custom-rest-source

Connect an arbitrary REST API to the PostHog data warehouse as a Custom source by authoring a JSON manifest, with no per-source code. Use when the user points at an API that has no built-in PostHog connector — "import data from this REST API", "sync my internal API", "connect this API from its docs", "build a custom data warehouse source" — and gives a docs URL or a natural-language description of the endpoints. Walks through drafting the RESTAPIConfig manifest (auth — bearer, API key, HTTP basic, or OAuth2 client credentials / refresh token — pagination, record path, incremental cursor, parent/child fan-out), validating it, test-reading live rows to verify the field mappings, and creating the source. If the API already has a native PostHog connector, use setting-up-a-data-warehouse-source instead — this skill checks the connector registry first and only handles APIs with no native connector.

io.github.PostHog/posthog/diagnosing-stacktrace-symbolication

Help users debug PostHog Error Tracking stack-trace symbolication for any supported platform — JavaScript/TypeScript web, React Native (Hermes), Android (Proguard / R8), or iOS / macOS (dSYM). The PostHog symbol-set lookup flow is universal across platforms; build-tool and artifact details live in per-platform references (JavaScript is fleshed out, others come as we encounter them). Use when stack frames stay minified or obfuscated after symbols are uploaded, PostHog symbol sets show last_used but frames are not readable, chunk IDs or dSYM UUIDs do not match, "Token not found" appears, uploaded source maps / dSYMs / Proguard mappings look empty, or bundler / symbol-upload configuration needs troubleshooting.

io.github.PostHog/posthog/designing-email-templates

Author, save, and edit email templates in the PostHog workflows library — compose email design JSON with Liquid personalization and create and round-trip-edit templates over MCP. Use when asked to design, build, update, or fix an email template for workflows, broadcasts, or campaigns.
