Use when the task requires automating a real browser from the terminal (navigation, form filling, snapshots, screenshots, data extraction, UI-flow debugging) via `playwright-cli` or the bundled wrapper script.

Use the Figma MCP server to fetch design context, screenshots, variables, and assets from Figma, and to translate Figma nodes into production code. Trigger when a task involves Figma URLs, node IDs, design-to-code implementation, or Figma MCP setup and troubleshooting.

Update, deploy, or roll out a Tinybird pipe or datasource to staging or production. Use for "update a pipe", "push to Tinybird", "tb push", "tb pull", "change a datasource", "add a field to a pipe", or anything touching the `lfx_insights` / `lfx_insights_stg` Tinybird workspaces.

Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP), Node/TypeScript (MCP SDK), or C#/.NET (Microsoft MCP SDK).

Reviews UI code (Slim/HTML, CSS, Stimulus/JS) for usability problems against Nielsen's 10 usability heuristics and the Laws of UX, and reports them as a ranked issue log with evidence and fixes. Use when asked for a UX review, UI review, usability audit, heuristic evaluation, or "is this usable", when checking a new screen or flow before it ships, or when the user mentions Nielsen, heuristics, Fitts's Law, Hick's Law, or another Law of UX.

This skill should be used when the user asks to "review this PR in a webpage", "review offline", "open a review page", "review the diff together in the browser", "collect my review comments in a markdown file", or invokes /review-offline. Opens an interactive local page, with an animated change diagram and pre-loaded agent suggestions, where the user triages comments, and saves the accepted ones to `.reviews/<slug>.md`. Never posts, pushes or edits. For an autonomous review use pm-cr; for a narrated walkthrough use codestory.

Use when: putting a new or existing feature behind a feature flag (dev feature) in OpenCTI, adding attributes, GraphQL endpoints, managers or UI that must be hidden until a flag is enabled, or removing a feature flag

Analyzes, builds, modifies, and adds explainer text cards to Mixpanel dashboards with the mixpanel_headless Python library. It reads a dashboard's layout and runs every report on it, creates dashboards with text cards and a grid layout, edits cells and rows in place, and writes data-driven explainer cards. Use when the user asks to analyze, summarize, explain, build, create, redesign, update, reorganize, or clean up a Mixpanel dashboard; asks about dashboard layout, rows, cell widths, text cards, or which chart type suits a board; or wants to turn queries into reports placed on a dashboard. Do not use for general analytics questions or one-off queries (use mixpanelyst), or for what a specific user did in a session recording (use session-replay).

Enforces Feature-Sliced Design (FSD) architecture in React/TypeScript projects by scaffolding compliant folder structures, validating layer boundaries and import directions, detecting and fixing layer violations, and teaching FSD conventions during code generation and review. Use when asked to 'create a page', 'add an entity', 'build a widget', 'scaffold FSD structure', 'refactor to FSD', 'where should I put this code', 'what layer does X go in', 'organize my React code', 'fix layer violation', or 'review my FSD structure'. Triggers on any React/TypeScript task involving FSD layers, slices, segments, cross-layer imports, or public API boundaries. Covers code structure and layer boundaries only — for rendering performance use react-best-practices, for language and typing questions use typescript-development.

Initialize warehouse schema discovery. Generates .astro/warehouse.md with all table metadata for instant lookups. Run once per project, refresh when schema changes. Use when user says "/astronomer-data:warehouse-init" or asks to set up data discovery.

Posts review findings from a JSON file as inline comments on a GitHub Pull Request, attaching each comment to its file and line. Use when you have a list/JSON of review findings (each with a file path, line number, and a message such as summary/failure_scenario) and want them published on a PR as inline review comments. Triggers include "post these review comments on the PR", "associate comments to files in the PR", "publish review findings to PR

Migrate an existing Apple/Swift Expo native module from the Expo Modules API 1.0 definition DSL to the 2.0 macro API (sometimes called v2) while preserving its JavaScript and TypeScript contract. Use when converting or incrementally adopting @ExpoModule, @JS, @Event, @SharedObject, or @Record in an existing module. Do not use for creating a new module, general Expo SDK upgrades, or Android/Kotlin migrations.

Use when changing the structure of working code without changing its behavior: decomposing an oversized function, extracting or merging a module, collapsing a layer, breaking an import cycle. Applies when the edit is structural enough to need a plan and explicit approval before it lands. Triggers: 'refactor this', 'decompose this function', 'split this module', 'break this dependency cycle', 'extract this into', 'restructure', 'work through the deferred items'. Not for slop cleanup (use simplify), judging a change (use code-review), fixing bugs, or adding behavior.

Master defensive Bash programming techniques for production-grade scripts. Use when writing robust shell scripts, CI/CD pipelines, or system utilities requiring fault tolerance and safety.

Send SMS messages with Azure Communication Services SMS Java SDK. Use when implementing SMS notifications, alerts, OTP delivery, bulk messaging, or delivery reports.

Build production Apache Airflow DAGs with best practices for operators, sensors, testing, and deployment. Use when creating data pipelines, orchestrating workflows, or scheduling batch jobs.

Azure AI Content Safety SDK for Python. Use for detecting harmful content in text and images with multi-severity classification.

Azure AI Content Understanding SDK for Python. Use for multimodal content extraction from documents, images, audio, and video.

This skill should be used when the user asks to "set up release please", "configure automated releases", "manage version numbers", "add changelog automation", or mentions release-please, semantic versioning, or monorepo versioning.

Create, list, inspect, update, or delete AgentMail inboxes through the connected MCP server. Use for ANY inbox lifecycle request — even a quick list-inboxes or a simple delete; deletion safeguards apply regardless of task size. Also use when the user asks for a new agent email address, wants inbox details changed, or removes an inbox; do not use for sending mail (agentmail-send-email), reading or triage (agentmail-check-email), or MCP connection setup (agentmail-mcp).
