Debug a failing test using an iterative logging approach, then clean up and document the learning.

VS Code settings precedence rules and common pitfalls. Essential for any code that reads or writes settings. Covers getConfiguration scope, inspect() vs get(), and multi-workspace handling.

Critical patterns for cross-platform path handling in this VS Code extension. Windows vs POSIX path bugs are the #1 source of issues. Use this skill when reviewing or writing path-related code.

Make HTTP requests with automatic x402 payment support using the purl command line interface.

Run smoke tests to verify extension functionality in a real VS Code environment. Use this when checking if basic features work after changes.

Run integration tests to verify that extension components work together correctly. Use this after modifying component interactions or event handling.

Run the mandatory pre-commit checks before committing code. Includes lint, type checking, and unit tests. MUST be run before every commit.

Keep dependencies up-to-date. Discovers outdated deps via dependabot alerts/PRs, creates one PR per ecosystem, iterates until CI is green, then assigns for review.

Use Fabric CLI for Power BI operations — semantic models, reports, DAX queries, refresh, gateways. Activate when users work with Power BI items, need to refresh datasets, execute DAX, manage reports, or troubleshoot refresh failures.

Use Microsoft Fabric CLI (fab) to manage workspaces, semantic models, reports, notebooks, and Fabric resources. Activate when users mention fab, Fabric CLI, or need to automate Fabric operations.

All changes for the release (dependency updates, bug fixes, etc.) should already be merged to `main`.

Measure and improve code coverage in the Duroxide durable execution runtime. Use when asked about coverage, testing coverage, running llvm-cov, or improving test coverage percentages.

Build React-hosted 3D browser games with React Three Fiber and the pmndrs stack. Use when the user wants a 3D scene inside a React app, declarative scene composition, shared app state, or React-native UI coordination around a clean low-chrome 3D experience.

Migrate an existing connected Google Slides deck onto a company or team template in Codex. Use when a user wants to restyle a deck to match a template, port content from a source presentation into a branded template deck, or rebuild slides by duplicating template patterns rather than patching the old layout in place.

Prepare and optimize GLB or glTF assets for browser games. Use when the user needs help with model formats, Blender export, optimization, compression, texture packaging, collision proxies, LOD, or shipping 3D assets cleanly across Three.js, React Three Fiber, Babylon.js, or PlayCanvas.

Analyze Google Sheets data, plan range-precise edits, and help with formulas or tabular transformations through connected Google Sheets data. Use when the user wants to inspect tabs or ranges, summarize spreadsheet contents, propose formulas, clean or restructure tables, or update cells with explicit range-level intent.

Summarize Microsoft Teams chats and channels, extract action items, and draft follow-ups through connected Teams data. Use when the user wants to review a chat or channel, distill meeting discussions, identify owners and next steps, or prepare a safe reply or post without sending it by default.

Plan and route browser-game work with a 2D-first default. Use when the user wants help designing, implementing, asseting, or playtesting a browser game and needs the right stack, workflow, and specialist skill routing.

Manage Gmail inbox triage, thread summaries, action extraction, and reply drafting through connected Gmail data. Use when the user wants to inspect a mailbox or thread, summarize messages, extract decisions and follow-ups, prepare replies or forwards, or organize messages with explicit confirmation before send, archive, or delete actions.

Restructure connected Google Slides decks in Codex when local slide cleanup is not enough. Use when repeated alignment or overlap issues come from the slide structure itself, when the same fix must be applied across many slides, or when raw Slides batch_update requests need stricter recipes and verification to avoid hallucinated params or broken layouts.
