Use for a thermo-nuclear code quality review, thermonuclear review, deep code quality audit, or especially harsh maintainability review — abstraction quality, giant files, and spaghetti-condition growth.

Keep the AG-UI .NET SDK at feature and wire-format PARITY with the canonical reference SDKs (TypeScript is the source of truth; Python is types/encoder only). USE FOR: porting a feature/event/behavior that landed in the TS (or Python) SDK into .NET, verifying the .NET wire format (JSON, SSE, protobuf) matches the reference, locating where the reference implementation and compatibility fixtures live, mapping a TS concept to the .NET event/client/encoder model, resolving an upstream protocol fix (e.g. a Microsoft.Extensions.AI / Microsoft Agent Framework issue) that needs a .NET counterpart, deciding which .NET package owns a change. DO NOT USE FOR: the mechanics of writing a specific test (use agui-dotnet-unit-tests for serialization round-trips, agui-dotnet-integration-tests for cross-language / E2E harness mechanics, agui-dotnet-wire-types for JSON/proto type rules, agui-dotnet-transport for SSE/HTTP transport details). This skill is about the PARITY PROCESS and where the reference lives, not test authoring.

Deep code review of a single open PR in nrwl/nx. Checks the PR out only inside an isolated sandbox, then runs four fixed reviewers: implementation (correctness, errors, types, performance), verification (tests, ticket grounding, comments, and docs), approach, and security. A reproduce-verifier executes a runnable repro only when verification identifies one. The skill saves a GitHub-flavored draft to ~/.nx-pr-reviews/<NUMBER>.md and never posts it. Claude reads/executes PR code only through the sandbox CLI; credentials never enter the sandbox.

Route a "how do I use Codewhale" question to the installed help, config, and doctor surfaces instead of reciting a manual from memory. Explicit-only.

Help a new contributor get productive on this checkout - inspect sync state against main, build, run the repository's exact verification gate, and produce a local what's-new digest. Never fetches, pulls, or modifies a dirty tree on its own. Explicit-only.

Plan and then execute a migration of a project from the mem0 open-source / self-hosted SDK (the local `Memory` class) to the mem0 Platform / hosted / managed SDK (the `MemoryClient` class). Use this whenever a developer wants to move, switch, or migrate their mem0 usage off OSS/self-hosted to the hosted API — e.g. "migrate my mem0 setup to the platform", "switch from self-hosted mem0 to MemoryClient", "use my mem0 API key instead of a local Qdrant", "move mem0 to the cloud/hosted/managed service", or "replace my local mem0 vector store + embedder config with the platform". Applies to Python (`from mem0 import Memory` → `from mem0 import MemoryClient`) and TypeScript/JavaScript (`import { Memory } from "mem0ai/oss"` → `import MemoryClient from "mem0ai"`). Trigger even when the user doesn't say the word "migrate" but clearly wants their existing mem0 integration to run against the hosted platform. It first produces a reviewable migration plan, then executes it after the developer approves. Strictly scoped to the mem0 integration — it does not refactor, restructure, or "improve" any unrelated code.

Configure MCP servers for n8n development in OpenCode. Use when the user says /setup-mcps or asks to set up MCP servers for n8n.

Configure MCP servers for n8n development. Use when the user says /setup-mcps or asks to set up MCP servers for n8n.

Guides adding, changing, and reviewing telemetry through the `@n8n/telemetry` event registry. Use when working on telemetry, analytics, tracking, product events, `track()` calls, or RudderStack/PostHog product events, in frontend or backend code — and whenever you need to find which registered telemetry events exist, what an event means, or what properties it carries.

Reproduce a bug from a Linear ticket with a failing test. Expects the full ticket context (title, description, comments) to be provided as input.

Applies n8n's RBAC scope decorators to REST endpoints. Use when creating a new @RestController, adding any @Get/@Post/@Put/@Patch/@Delete route to an existing controller, or reviewing endpoint authorization. Every authenticated endpoint must be gated by @ProjectScope or @GlobalScope.

Add OAuth2 credential support to an existing n8n node — creates the credential file, updates the node, adds tests, and keeps the CLI constant in sync. Use when the user says /node-add-oauth.

Fetch and analyze Linear issue with all related context. Use when starting work on a Linear ticket, analyzing issues, or gathering context about a Linear issue.

Create new ESLint rules for the @n8n/eslint-plugin-community-nodes package. Use when adding a lint rule, creating a community node lint, or working on eslint-plugin-community-nodes. Guides rule implementation, tests, docs, and plugin registration.

Checks if a community pull request is ready for human review. Verifies CLA signature, PR title format, description completeness, test coverage, and cubic-dev-ai issues, then triages to the right Linear team or recommends a close. Use when given a PR number or branch name to review, or when the user says /community-pr-readiness-check, or asks to check if a PR is ready for review.

Teach the user a new skill or concept, within this workspace.

Manually-invoked skill that forces the agent to compress its current answer — strip filler, simplify wording, and cut length while keeping the substance. Use when the user says "short", "shorter", "simpler", "too long", "tl;dr", or wants a more concise version of the previous response.

Rewrite the last response simpler and shorter in plain English, prefixed with a 3-5 sentence TLDR of the conversation so far. Manual-only, invoked as /remind.

Read every ADR markdown file in the project's docs/adr/ folder so you have full context on past decisions. Use only when the user explicitly calls it.

Prompt David with pointed questions to extract what is in his head about a project — remaining work, what is being avoided, what really matters, what does not. Use when David says "prompt me", "ask me questions", or wants the agent to figure out priorities by questioning him.
