Build, run, and visually iterate on terminal UIs without human screenshots. Captures TUI output as PNG images using a headless terminal renderer. Use when building TUIs, CLI tools with visual output, or any terminal program where you need to see what it looks like. Triggers on "build a TUI", "make a terminal UI", "how does it look", "screenshot the terminal", "visual feedback loop".

Create, modify, validate, publish, and visually review Grafana dashboards. Use when building dashboards, editing panels/variables/links, finding dashboard examples, using gcx, or taking Playwright screenshots of Grafana dashboards.

Rebuild the SkyWalking distribution and OAP Docker image after source changes. Use before running e2e tests so the image reflects your code changes. Avoids the "image looks updated but runtime has stale jars" trap.

Databricks Model Serving endpoint lifecycle and ops. Use when asked to: CRUD serving endpoints (CLI or MLflow Deployments client); configure traffic routing for A/B / canary deploys and zero-downtime version swaps; retrieve OpenAPI schemas; inspect logs, metrics, or permissions; manage AI Gateway rate limits; discover Foundation Model API endpoints at runtime; integrate endpoints into Databricks Apps; or stream from off-platform clients (Vercel AI SDK v6, standalone Node.js). NOT for: training, MLflow autologging, UC registration, custom PyFunc/ResponsesAgent authoring (databricks-ml-training); Knowledge Assistants/Supervisor Agents (databricks-agent-bricks); MLflow evaluation (databricks-mlflow-evaluation).

Review and triage PR review comments on the current branch — groups threads by file, separates bots from humans, walks through unresolved comments interactively

Use Symphony's `linear_graphql` client tool for raw Linear GraphQL operations such as comment editing and upload flows.

Pull latest origin/main into the current local branch and resolve merge conflicts (aka update-branch). Use when Codex needs to sync a feature branch with origin, perform a merge-based update (not rebase), and guide conflict resolution best practices.

Push current branch changes to origin and create or update the corresponding pull request; use when asked to push, publish updates, or create pull request.

Create or update component documentation in Sentry's MDX stories format. Use when asked to "document a component", "add stories", "write component docs", "create an mdx file", "add a stories.mdx", or document a design system component. Generates structured MDX with live demos, accessibility guidance, and auto-generated API docs from TypeScript types.

Guide for creating, updating, and deprecating hybrid cloud RPC services in Sentry. Use when asked to "add RPC method", "create RPC service", "hybrid cloud service", "new RPC model", "deprecate RPC method", "remove RPC endpoint", "cross-silo service", "cell RPC", or "control silo service". Covers service scaffolding, method signatures, RPC models, cell resolvers, testing, and safe deprecation workflows.

Guide for adding new actions to Sentry's Command+K palette. Use when implementing new cmdk actions, registering page-level or global actions, building async resource pickers, or adding contextual actions to a view.

Generate snapshot test files for Sentry frontend React components. Use when asked to "generate snapshot tests", "add snapshot tests", "create visual snapshots", "write snapshot tests", "add visual regression tests", or "snapshot this component". Accepts an optional component path or name via $ARGUMENTS.

Generate hybrid cloud tests for the Sentry codebase. Use when asked to "generate HC test", "create hybrid cloud test", "write HC test", "add HC test", "write RPC test", "test RPC service", "silo test", "cross-silo test", "outbox test", "API gateway test", or "endpoint silo test". Covers RPC service tests, API gateway tests, outbox pattern tests, and API endpoint tests with silo decorators.

Use when writing, modifying, or debugging unit tests (*.test.tsx) in the orchestration cluster webapp (webapp/client/apps/orchestration-cluster-webapp/src/). Covers Vitest browser mode, MSW mocking, and vitest-browser-react rendering.

Decomposes PRDs and TechSpecs into detailed, independently implementable task files with enrichment from codebase exploration. Use when a PRD or TechSpec exists and needs to be broken down into executable tasks, or when task files need enrichment with implementation context. Do not use for PRD creation, TechSpec generation, or direct task execution.

Expert in asynchronous programming patterns across languages (Python asyncio, JavaScript/TypeScript promises, C# async/await, Rust futures). Use for concurrent programming, event loops, async patterns, error handling, backpressure, cancellation, and performance optimization in async systems.

Writing conventions for scannable, token-efficient skills and prompts. Use when creating or reviewing SKILL.md files, AGENTS.md files, or any markdown-based agent instruction documents.

Guide for using Netlify Blobs for file and asset storage — images, documents, uploads, exports, cached binary artifacts. Covers getStore(), CRUD operations, metadata, listing, deploy-scoped vs site-scoped stores, and local development. Do NOT use Blobs as a dynamic data store — use Netlify Database for that.

Discover APIs published in an API Experience Hub portal as a portal consumer. Use when an end user needs to browse the catalog, search assets by keyword or filter, open an API's detail page, read its terms and conditions, or fetch rendered documentation pages and resources.

Perform structured reconnaissance and attack surface enumeration for authorized penetration tests, CTF challenges, and bug bounty programs. Use when the user mentions 'recon,' 'reconnaissance,' 'enumerate,' 'attack surface,' 'subdomain enumeration,' 'port scan,' 'fingerprint,' 'asset discovery,' or needs to map a target's external footprint.
