Use when solution space exploration is complete and you're ready to create an implementation plan. Enforces "simple over easy" - the fundamentally right solution, not the path of least resistance. Triggers after /design-solution, when a solution has been chosen, or when asked to "make a plan" or "create a plan".
Use this for exploratory data analysis (EDA), generating visualizations, finding trends, and deriving insights from datasets using Python (Pandas/Seaborn/Plotly) or SQL.
Applies Anthropic's official brand identity including colors (Dark #141413, Light #faf9f5, Orange #d97757), typography (Poppins, Lora), and design standards to artifacts, presentations, documents, and web interfaces. Use when asked to "apply Anthropic branding", "use brand colors", "style with company guidelines", "add Anthropic look-and-feel", or "follow design standards". Provides official color palettes, font specifications, logo usage, and visual formatting rules. Works with HTML artifacts, presentations, PDFs, documents, and any visual deliverables requiring consistent brand identity.
Manual QA testing — verify features end-to-end as a user would, using every tool available (browser, macOS, bash, APIs). Focuses on what formal test suites cannot capture: visual correctness, UX flows, usability judgment, integration reality, edge cases, and failure modes. Standalone or composable with /ship. Triggers: qa, qa test, manual test, test the feature, verify it works, exploratory testing, smoke test, end-to-end verification.
Smart database query skill. Connect to online databases via SSH tunnel, supporting natural language to SQL conversion, query execution, and table structure exploration. Use this skill when you need to query databases, ask about data, or view table structures.
IoT protocols: Zigbee (mesh), Z-Wave (home), LoRaWAN (long-range), CoAP (lightweight), Matter (interoperable), Thread (I
Debug and synchronize communication between the robocar main controller (Heltec WiFi LoRa 32) and camera module (ESP32-CAM)
Strict Red-Green-Refactor workflow for robust, self-documenting code. Discovers project test setup via codebase exploration before assuming frameworks. Use when: (1) Implementing new features with test-first approach, (2) Fixing bugs with reproduction tests, (3) Refactoring existing code with test safety net, (4) Adding tests to legacy code, (5) Ensuring code quality before committing, (6) When tests exist but workflow unclear, or (7) When establishing testing practices in a new project. Triggers: test, tdd, red-green-refactor, failing test, test first, test-driven, write tests, add tests, run tests.
Use when writing or running Nushell commands, scripts, or pipelines - via the Nushell MCP server (mcp__nushell__evaluate), via Bash (nu -c), or in .nu script files. Also use when working with structured data (JSON, YAML, TOML, CSV, Parquet, SQLite), doing ad-hoc data analysis or exploration, or when the user's shell is Nushell.
Skill for Playwright-driven web UI testing, exploration, test generation, execution, and debugging (TypeScript or Python). Triggers for tasks involving application testing, validation, test generation, or UI automation in web applications.
Cheminformatics provides computational chemistry workflows using RDKit for molecular property prediction, virtual screening, ADMET analysis, molecular docking preparation, and chemical space exploration.
Interview the user relentlessly about a plan or design until reaching shared understanding, resolving each branch of the decision tree. Use when user wants to stress-test a plan, get grilled on their design, or mentions "grill me".
