- frontend-testing-strategymodem-dev/ossrulesWrite unit and E2E tests for Grafana frontend code (React/TypeScript, any package or feature area) to the conventions this repo expects. Use when adding, backfilling, or reviewing frontend tests; when a test only asserts "it rendered" or "it's defined"; when reviewing AI-generated tests for slop; or when a frontend test is flaky. For visualization panels and grafana-ui viz components specifically, also load the `panel-testing-strategy` skill.TestingNo warnings★ 64↓ —
- qwik-router-developmentmodem-dev/ossrulesUse when modifying or reviewing Qwik Router code under packages/qwik-router, including runtime routing, buildtime route generation, middleware, adapters, SSG, markdown/MDX handling, or router tests.TestingNo warnings★ 64↓ —
- remixmodem-dev/ossrulesBuild and review Remix 3 applications using the `remix` npm package and subpath imports.

- seldonframe-agent-businessseldonframe/seldonframeUse when a builder working in an IDE agent (Claude Code, Cursor, Codex) wants to build, test, deploy, sell, or get paid for an AI agent on SeldonFrame — e.g. "build me a receptionist agent and sell it", "deploy my agent to a real phone number", "list my agent on the marketplace", "run my agent's evals", "withdraw my agent earnings" — or when the SeldonFrame MCP (@seldonframe/mcp) is connected and the user asks what to do next.TestingNo warnings★ 64↓ —
- verify-buildseldonframe/seldonframeSeldonFrame merge gate — run unit tests + tsc + check-use-server + migration-journal + regression-grep and return ONE pass/fail verdict. Invoke before merging any branch; nothing merges without a green verdict.TestingNo warnings★ 64↓ —
- block-creationseldonframe/seldonframeScaffold a new SeldonFrame block from a natural-language intent. Use when the builder says "build me a block that ...", "scaffold a block that ...", or similar. Produces a real, validated block skeleton in packages/crm/src/blocks/ — BLOCK.md with composition contract, tools.ts with Zod schemas, subscription handler stubs (when reactive), and test.todo stubs per tool. Does NOT commit, does NOT install into any workspace. Builder owns review + git.TestingNo warnings★ 64↓ —
- electron-node-upgrademodem-dev/ossrulesGuide for performing Node.js version upgrades in the Electron project. Use when working on the roller/node/main branch to fix patch conflicts during `e sync --3`. Covers the patch application workflow, conflict resolution, analyzing upstream Node.js changes, building, running the Node.js test suite, and proper commit formatting for patch fixes.TestingNo warnings★ 64↓ —
- qwik-docs-developmentmodem-dev/ossrulesUse when writing, modifying, or reviewing Qwik docs content or docs-site code under packages/docs, including docs routes, MDX content, generated LLM outputs, docs build behavior, or docs-specific e2e tests.TestingNo warnings★ 64↓ —
- qwik-core-developmentmodem-dev/ossrulesUse when modifying or reviewing Qwik core package code under packages/qwik, especially reactive primitives, signals, VNodes, cursor behavior, QRLs, optimizer-facing runtime behavior, or Qwik core tests.TestingNo warnings★ 64↓ —
- qwik-e2e-verificationmodem-dev/ossrulesUse when creating, modifying, debugging, or running Qwik Playwright e2e tests under e2e/, including router, adapters, docs, CLI, and React integration suites.TestingNo warnings★ 64↓ —
- testing-codegenmodem-dev/ossrulesUse this skill when selecting or running Biome test fixtures, quick tests, `insta` snapshot workflows, expectation comments, orphan checks, or required code generators. Do not use for subsystem implementation design.TestingNo warnings★ 64↓ —
- preview-manual-testmodem-dev/ossrulesDiscover, wait for, sign in, create specific user data, and assert a PR preview deploy. Use on medium or high risk PRs, after pushing a ready-for-review PR, or when the user asks to test the preview URL.TestingNo warnings★ 64↓ —
- testing-changesmodem-dev/ossrulesRun the tests that cover a change in the pnpm repository, in the Rust workspace (pnpm/, pnpr/) or the TypeScript CLI (pnpm11/), and recognize the cases where a scoped run passes without testing anything. Use whenever verifying a change before committing or pushing, or when deciding what to run after an edit.TestingNo warnings★ 64↓ —
- coremodem-dev/ossrulesCore agent-browser usage guide. Read this before running any agent-browser commands. Covers the snapshot-and-ref workflow, navigating pages, interacting with elements (click, fill, type, select), extracting text and data, taking screenshots, managing tabs, handling forms and auth, waiting for content, running multiple browser sessions in parallel, and troubleshooting common failures. Use when the user asks to interact with a website, fill a form, click something, extract data, take a screenshot, log into a site, test a web app, or automate any browser task.TestingNo warnings★ 64↓ —
- kafka-shadowtraffic-javalensesio/agentic-engineering-for-apache-kafkaGenerate a TestContainers Java test class that spins up ShadowTraffic in-process to populate a Kafka topic with synthetic data during tests. Invokes the kafka-shadowtraffic skill to build the ShadowTraffic config, then adapts it for a containerized test network and scaffolds a JUnit 5 test class with Kafka, optional Schema Registry, and ShadowTraffic containers wired together. Use when the user says "set up a Java TestContainers test with ShadowTraffic", "write a Java test that generates Kafka data", "create a TestContainers test for my Kafka consumer", "I want to test my Kafka consumer with synthetic data in Java", or "scaffold a ShadowTraffic Java test". Do NOT use for non-Java projects, standalone Docker setups (use kafka-shadowtraffic instead), or creating Kafka topics.TestingNo warnings★ 65↓ —
- kafka-shadowtrafficlensesio/agentic-engineering-for-apache-kafkaGenerate a ShadowTraffic configuration to populate a Kafka topic with realistic synthetic data. Discovers the target topic, its key and value schemas, and the correct serializers from the live cluster via any attached Kafka MCP server, then writes a ready-to-run `shadowtraffic-config.json` and Docker command. Use when the user says "populate my Kafka topic with test data", "set up ShadowTraffic for topic X", "generate synthetic events into my topic", "I need fake data flowing into Kafka", "seed my topic with data", or "mock data for my Kafka topic". Do NOT use for creating topics, reviewing schemas, or building Kafka consumers.TestingNo warnings★ 65↓ —
- repo-health-checkDominikTobureto/awesome-grok-buildUse when auditing a repo before changes to find the smallest safe PR, quality risks, stale docs, missing tests, ignored-file gaps, or agent setup issues. Best first skill for unfamiliar codebases.TestingNo warnings★ 67↓ —
- pm-testswei63w/pm-managerList missing unit-test companions for core/changed sources. Do not write tests into the business tree unless the user confirms.TestingNo warnings★ 87↓ —
- skill-builderexistential-birds/beagleCreate Agent Skills with best practices, structure, validation, and testing. Use when designing or refining skills, prompts, references, or supporting files.TestingNo warnings★ 84↓ —
- prompt-improverexistential-birds/beagleOptimize prompts for code-related tasks following prompt-engineering best practices. Use when refining prompts for implementation, debugging, refactoring, code review, or testing.TestingNo warnings★ 84↓ —
- prfaq-beagleexistential-birds/beagleUse when the user wants to pressure-test a product, internal-tool, or OSS concept against Amazon's Working Backwards PRFAQ gauntlet before committing to a spec. Triggers on: "work backwards", "write a PRFAQ", "press release first", "is this idea worth building", "pressure-test this concept", "filter this before brainstorm", "is this a real product". Also catches solution-first pitches ("I want to build X that does Y") and technology-first pitches ("use AI to...") that need customer-first filtering. Produces a binary pass/fail verdict, not a polished doc. Hardcore coaching — direct, skeptical, concrete. On pass, hands off to brainstorm-beagle with a concept brief. Does NOT write code, plan implementation, scaffold projects, or draft specs.TestingNo warnings★ 84↓ —
