Development

Exploration symbolique du code avec Serena MCP. Utiliser pour naviguer dans le code par symboles (fonctions, classes, hooks), trouver des définitions, et comprendre l'architecture sans lire des fichiers entiers.

Orchestrate agile development workflows by invoking commands in sequence with checkpoint-based flow control. This skill should be used when the user asks to 'run the workflow', 'continue working', 'what's next', 'complete the task cycle', 'start my day', 'end the sprint', 'implement the next task', or wants guided step-by-step development assistance. Keywords: workflow, orchestrate, agile, task cycle, sprint, daily, implement, review, PR, standup, retrospective.

Backend Cloud Run/Express/Firestore do Sr Cardoso. Use quando criar ou alterar endpoints, auth JWT, regras de agenda, financeiro, branding, WhatsApp, cron jobs, ou modelagem Firestore.

Modern CSS standards covering essentials, responsive design, quality practices, and tooling for CUI projects

Perform DuckDuckGo web searches and return structured results. WHEN: User wants to "search the web", "find information online", "look up", "research topic". WHEN NOT: Know exact URL (use browser_navigate), crawling sites (use scrape_url).

CPU profiling, benchmarking, and memory analysis for Rust applications. Use when code is slow, memory usage is high, or optimization is needed.

Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies

Integrate new DEX aggregators, swappers, or bridge protocols (like Bebop, Portals, Jupiter, 0x, 1inch, etc.) into ShapeShift Web. Activates when user wants to add, integrate, or implement support for a new swapper. Guides through research, implementation, and testing following established patterns. (project)

Enforces universal strict governance rules (500 lines, 5 funcs, 4 args) and interface-first I/O for Python, Golang, and .NET.

This skill should be used when you need AI debate with multiple perspectives, analyzing trade-offs, evaluating pros and cons, deep code analysis, or multi-model reasoning. Ideal for subjective decisions, architectural trade-offs, and complex problems requiring synthesis of different viewpoints. Complements opus-subagent for structured multi-step workflows.

Writes E2E and component tests with Cypress including selectors, commands, fixtures, and API testing. Use when testing web applications end-to-end, testing user flows, or writing integration tests.

Creates navigation structures following the app's nested navigator pattern. Handles type-safe navigation, stack and tab setup, and screen parameter management in Purrsuit Mobile App.

Use this skill to query your Google NotebookLM notebooks directly from Claude Code for source-grounded, citation-backed answers from Gemini. Browser automation, library management, persistent auth. Drastically reduced hallucinations through document-only responses.

Solve Advent of Code puzzles, algorithm challenges, and competitive programming problems. Activate when user provides AoC problem context/input, mentions solving puzzles/challenges, asks about algorithm selection (BFS, DFS, DP, etc.), or needs help with parsing structured input.

Control Autodesk Fusion 360 CAD software via the Claude Bridge add-in. Create sketches, draw shapes, extrude 3D objects, and build complex models interactively.

Expert on Anthropic Claude API, models, prompt engineering, function calling, vision, and best practices. Triggers on anthropic, claude, api, prompt, function calling, vision, messages api, embeddings

Auto-generate renderers, calculate statistics, and create data-driven visualizations. Use for class breaks, unique values, heatmaps, dot density, relationship maps, and getting histogram/summary statistics.

Load feature requirements, design, and implementation plan when working on in-progress features. Use when user is implementing code, debugging, asking about requirements, or making changes related to a tracked feature. Silently loads context files to inform responses.

Build AI-native applications with AI SDK v5. Use when integrating LLMs (OpenAI, Anthropic, Gemini) for text generation, streaming, structured outputs, embeddings, image generation, or audio processing. Covers setup, core workflows, provider selection, and advanced features like reasoning, caching, and tool usage.

Manages internationalization strings and translation workflows using i18next and react-i18next. Use when adding new text, supporting additional languages, or implementing pluralization and interpolation in Purrsuit Mobile App.
