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.}
