Prepare and execute an Android release (patch/minor/major)

Author animated technical explainer diagrams as .anim.json files for Nimbalyst's Animation editor. Use when the user wants to animate a diagram, show how a system/protocol/algorithm behaves over time, build a motion explainer, or turn a static architecture diagram into something that plays.

Gather details and draft an actionable bug report for developers.

Author Nimbalyst Project Canvas boards (.canvas files) — an infinite canvas whose cards are live editors for real workspace files and shared documents, arranged spatially and wired with edges. Use when the user asks for a canvas, a board, a spatial layout of documents or mockups, a flow of screens, or a workspace overview.

Create a new plan document for tracking work.

Run E2E tests in a dev container (isolated environment)

Run E2E tests in a dev container for isolated, reproducible test execution. Use proactively when asked to run Playwright tests, E2E tests, or when in a worktree. Handles the full Docker container lifecycle automatically.

Create diagrams and visual drawings using Excalidraw (.excalidraw files). Use when the user wants flowcharts, architecture diagrams, system diagrams, sketches, or any visual diagram. For database schemas and entity relationship diagrams, use the DataModelLM extension instead.

Build, install, and hot-reload Nimbalyst extensions using MCP tools. Use when developing, testing, or iterating on Nimbalyst extensions.

Help the user file a bug report or feature request for Nimbalyst. Activates when the user opens the in-app feedback flow or runs /feedback:bug-report or /feedback:feature-request. Coordinates evidence gathering, anonymization, and posting to GitHub Issues.

Create git commits using Nimbalyst's interactive commit proposal widget. ONLY use when the user explicitly clicks "Commit with AI" button or asks for "smart commit". For regular commit requests, use standard git commands instead.

Prepare and execute an iOS release (patch/minor/major)

Create a visual UX mockup for a requested feature or screen.

Create visual UX mockups using HTML/CSS files (.mockup.html). Use when the user wants to design UI, wireframes, visual layouts, or plan features visually.
