Everyday Dev Tasks

• // Refactor {a specific} file from {x} to {y}... _{General-purpose, applies to any language or repo.}

• // Add a test suite... _{Useful for repos lacking test coverage.}

• // Add type hints to {a specific} Python function... _{Python codebases transitioning to typed code.}

• // Generate mock data for {a specific} schema... _{APIs, frontends, or test-heavy environments.}

• // Convert these commonJS modules to ES modules... _{JS/TS projects modernizing legacy code.}

• // Turn this callback-based code into async/await... _{JavaScript or Python codebases improving async logic.}

• // Implement a data class for this dictionary structure... _{Useful for Python projects moving towards more structured data handling with dataclasses or Pydantic.}

Debugging

• // Help me fix {a specific} error... _{For any repo where you're stuck on a runtime or build error.}

• // Why is {this specific snippet of code} slow? _{Performance profiling for loops, functions, or queries.}

• // Trace why this value is undefined... _{Frontend and backend JS/TS bugs.}

• // Diagnose this memory leak... _{Server-side apps or long-running processes.}

• // Add logging to help debug this issue... _{Useful when troubleshooting silent failures.}

• // Find race conditions in this async code _{Concurrent systems in JS, Python, Go, etc.}

• // Add print statements to trace the execution flow of this Python script... _{For debugging complex Python scripts or understanding unexpected behavior.}

Documentation

• // Write a README for this project _{Any repo lacking a basic project overview.}

• // Add comments to this code _{Improves maintainability of complex logic.}

• // Write API docs for this endpoint _{REST or GraphQL backends.}

• // Generate Sphinx-style docstrings for this Python module/class/function... _{Ideal for Python projects using Sphinx for documentation generation.}

Testing

• // Add integration tests for this API endpoint _{Express, FastAPI, Django, Flask apps.}

• // Write a test that mocks fetch _{Browser-side fetch or axios logic.}

• // Convert this test from Mocha to Jest _{JS test suite migrations.}

• // Generate property-based tests for this function _{Functional or logic-heavy code.}

• // Simulate slow network conditions in this test suite _{Web and mobile apps.}

• // Write a test to ensure backward compatibility for this function _{Library or SDK maintainers.}

• // Write a Pytest fixture to mock this external API call... _{For Python projects using Pytest and needing robust mocking for testing.}

Package Management

• // Upgrade my linter and autofix breaking config changes _{JS/TS repos using ESLint or Prettier.}

• // Show me the changelog for React 19 _{Web frontend apps using React.}

• // Which dependencies can I safely remove? _{Bloated or legacy codebases.}

• // Check if these packages are still maintained _{Security-conscious or long-term projects.}

• // Set up Renovate or Dependabot for auto-updates _{Best for active projects with CI/CD.}

AI-Native Tasks

• // Analyze this repo and generate 3 feature ideas _{Vision-stage or greenfield products.}

• // Identify tech debt in this file _{Codebases with messy or fragile logic.}

• // Find duplicate logic across files _{Sprawling repos lacking DRY practices.}

• // Cluster related functions and suggest refactors _{Projects with lots of utils or helpers.}

• // Help me scope this issue so Jules can solve it _{For working with Jules on real issues.}

• // Convert this function into a reusable plugin/module _{Componentizing logic-heavy code.}

• // Refactor this Python function to be more amenable to parallel processing (e.g., using multiprocessing or threading)... _{For optimizing performance in computationally intensive Python applications.}

Context

• // Write a status update based on recent commits _{Managerial and async communication.}

• // Summarize all changes in the last 7 days _{Catching up after time off.}

Fun & Experimental

• // Add a confetti animation when {a specific} action succeeds _{Frontend web apps with user delight moments.}

• // Inject a developer joke when {a specific} build finishes _{Personal projects or team tools.}

• // Build a mini CLI game that runs in the terminal _{For learning or community fun.}

• // Add a dark mode Easter egg to this UI _{Design-heavy frontend projects.}

• // Turn this tool into a GitHub App _{Reusable, platform-integrated tools.}

Start from Scratch

• // What's going on in this repo? _{Great for legacy repos or onboarding onto unfamiliar code.}

• // Initialize a new Express app with CORS enabled _{Web backend projects using Node.js and Express.}

• // Set up a monorepo using Turborepo and PNPM _{Multi-package JS/TS projects with shared dependencies.}

• // Bootstrap a Python project with Poetry and Pytest _{Python repos aiming for clean dependency and test setup.}

• // Create a starter template for a Chrome extension _{Browser extension development.}

• // I want to build a web scraper—start me off _{Data scraping or automation tools using Python/Node.}
