50 Best Claude Code Prompts for Every Developer Workflow

Claude Code has become one of the most powerful AI coding agents available in 2026. But like any tool, the output quality depends entirely on the input. A vague prompt gets vague code. A precise, well-structured prompt gets production-ready solutions.

After months of building SuperBuilder -- a desktop app that wraps Claude Code with execution modes, debug tooling, and project management -- we have seen thousands of prompts from real developers. We know which ones consistently produce great results and which ones waste tokens.

This guide collects the 50 best Claude Code prompts across seven workflow categories, with practical tips on when to use each one and how to get even better results with SuperBuilder's execution modes.

How to Write Better Claude Code Prompts

Before diving into the prompts, here are the principles that separate mediocre prompts from great ones:

1. Be specific about the problem, not the solution. Tell Claude what is broken or what you need -- not how to implement it. Let the agent figure out the approach.
2. Include context about your stack. Claude Code can read your files, but explicitly naming the framework, language version, and key dependencies saves time.
3. State the constraints. "Don't add new dependencies," "keep backward compatibility," or "this must work in Node 18" dramatically improve output quality.
4. Describe the expected behavior. "When X happens, Y should occur" gives Claude a testable target.
5. One concern per prompt. Compound prompts that ask for three unrelated changes produce worse results than three focused prompts.

Bug Fixing Prompts (1-10)

Debugging is where Claude Code truly shines. These prompts help you squash bugs faster by giving Claude the right context upfront.

1. The Stack Trace Debugger

Prompt:

I'm getting this error when users submit the login form:

[paste stack trace]

The login form is in src/components/LoginForm.tsx and the auth handler is in src/api/auth.ts. The error only happens when the email contains a + character. Find the root cause and fix it.

When to use it: You have a stack trace and a reproducible scenario. This is the bread-and-butter debugging prompt.

Pro tip: Always include the file paths where the bug likely lives. Claude Code will read them, but pointing it in the right direction saves a round trip of file searching.

2. The Regression Hunter

Prompt:

The checkout flow was working yesterday but now throws a 422 error when applying discount codes. Nothing in the discount logic changed. Check recent changes to the cart, pricing, and API validation layers to find what broke it.

When to use it: Something that used to work is now broken and you are not sure which change caused it.

Pro tip: Pair this with git log --oneline -20 output pasted into the prompt so Claude can correlate file changes with the regression.

3. The Silent Failure Investigator

Prompt:

The webhook handler in src/webhooks/stripe.ts processes payment events but sometimes silently drops events without logging. No errors in the console. Check for unhandled promise rejections, missing await keywords, and early returns that skip processing.

When to use it: Something fails intermittently with no visible errors -- the worst kind of bug.

Pro tip: Explicitly suggest failure modes (missing await, swallowed catch blocks) to guide Claude toward common silent-failure patterns.

4. The Performance Bottleneck Finder

Prompt:

The /api/dashboard endpoint takes 8-12 seconds to respond. It queries the users, orders, and analytics tables. Profile the query logic in src/api/dashboard.ts and identify N+1 queries, missing indexes, or unnecessary data fetching. Suggest concrete fixes.

When to use it: An endpoint or function is unacceptably slow and you need a performance audit.

Pro tip: Include the approximate data scale (e.g., "users table has 500K rows") so Claude can reason about query performance realistically.

5. The Race Condition Detector

Prompt:

Users occasionally see stale data after updating their profile. The update API returns success but the subsequent GET sometimes returns old values. Check src/api/profile.ts and src/cache/user-cache.ts for race conditions between cache invalidation and database writes.

When to use it: Intermittent consistency bugs that smell like timing or concurrency issues.

Pro tip: This is an excellent candidate for SuperBuilder's debug mode, which generates hypotheses and tests them systematically instead of guessing.

6. The Environment-Specific Bug

Prompt:

This code works locally but fails in production with "ECONNREFUSED" on the Redis connection. The Redis URL is set via environment variable REDIS_URL. Check the connection setup in src/lib/redis.ts for hardcoded localhost references, missing TLS configuration, or connection string parsing issues.

When to use it: Works on my machine but not in production/staging/CI.

Pro tip: List the differences between environments (Docker vs bare metal, different Node versions, TLS requirements) to help Claude narrow down the cause.

7. The Type Error Untangler

Prompt:

TypeScript build fails with 23 errors after upgrading from React 18 to React 19. Most errors are in component props and event handlers. Fix the type errors while maintaining the same runtime behavior. Don't change any business logic.

When to use it: A dependency upgrade or TypeScript version bump breaks your build.

Pro tip: Add "fix one file at a time and explain each change" if you want to review carefully, or "fix all of them" if you trust the agent and want speed.

8. The Memory Leak Hunter

Prompt:

The Node.js process memory grows from 200MB to 2GB over 24 hours. The main suspect is the WebSocket connection manager in src/ws/connection-pool.ts. Check for event listener leaks, unreleased references in Maps/Sets, and missing cleanup in disconnect handlers.

When to use it: Your application has a memory leak and you have a suspected area.

Pro tip: If you have heap snapshot data or process.memoryUsage() logs, paste them in. Quantitative data helps Claude prioritize likely causes.

9. The CSS Layout Debugger

Prompt:

The modal component in src/components/Modal.tsx renders behind the sidebar on mobile screens (< 768px). The sidebar has z-index: 100. The modal should always appear on top. Fix the stacking context issue without changing the sidebar's z-index.

When to use it: Visual layout bugs, especially z-index and stacking context issues.

Pro tip: Include the viewport dimensions and which browsers are affected. CSS bugs are often browser-specific.

10. The Data Corruption Investigator

Prompt:

Some users have null values in the `subscription_tier` column even though the column has a NOT NULL constraint at the application level. Check the user creation flow in src/api/users.ts, the Stripe webhook handler in src/webhooks/billing.ts, and any direct database queries that might bypass the ORM validation.

When to use it: Your data has impossible states that your application logic should prevent.

Pro tip: Use SuperBuilder's debug mode here. It will generate hypotheses about how null values could enter the column and test each path systematically.

Feature Building Prompts (11-20)

Building new features is where prompt clarity pays the highest dividends. These prompts help Claude Code produce well-structured, production-ready implementations.

11. The Full Feature Spec

Prompt:

Add a notification preferences page to the settings. Users should be able to toggle email notifications for: new comments, mentions, weekly digest, and marketing. Store preferences in the existing user_settings table (add columns if needed). Create the API endpoint, the React component, and wire them together. Use the same UI patterns as the existing ProfileSettings component.

When to use it: You have a clear feature spec and want Claude to implement the full vertical slice.

Pro tip: Referencing an existing component as a style guide ("use the same patterns as X") is one of the most effective Claude Code tips. It reduces ambiguity dramatically.

12. The API Endpoint Builder

Prompt:

Create a REST API endpoint POST /api/v1/teams/:teamId/invitations that sends an email invitation to join a team. Validate that the requesting user is a team admin. Check that the invited email isn't already a team member. Store the invitation with a unique token and 72-hour expiry. Return 201 with the invitation details. Follow the same error handling pattern used in src/api/v1/teams/members.ts.

When to use it: You need a new API endpoint with clear business rules.

Pro tip: Always specify the HTTP method, path, validation rules, and response shape. The more specific the contract, the better the implementation.

13. The Database Migration Creator

Prompt:

Create a database migration that adds a `teams` table with: id (uuid, primary key), name (varchar 255, not null), slug (varchar 100, unique, not null), owner_id (uuid, foreign key to users), created_at, updated_at. Add an index on owner_id. Use the same migration format as existing files in src/db/migrations/.

When to use it: You need a new table or schema change with specific column definitions.

Pro tip: Always mention the migration format/tool (Knex, Prisma, Drizzle, raw SQL) and point to an existing migration as a template.

14. The UI Component Builder

Prompt:

Create a reusable DataTable component that accepts: columns (array of { key, header, render? }), data (array of objects), onSort (callback), sortColumn, sortDirection, and optional emptyState. Support sticky headers, row hover, and column-level custom renderers. Use the existing design tokens in src/styles/tokens.ts. No external table libraries.

When to use it: Building a reusable component with a well-defined API.

Pro tip: Listing the props interface upfront is the single most effective thing you can do for component prompts. Claude will match the interface exactly.

15. The Integration Connector

Prompt:

Add Slack integration that posts a message to a configured channel when a new support ticket is created. Create a SlackService class in src/services/slack.ts with methods: sendTicketNotification(ticket), verifyWebhook(payload), and configure(webhookUrl). Use the Slack Incoming Webhooks API. Add error handling with retries (max 3, exponential backoff).

When to use it: Integrating with a third-party service with a known API.

Pro tip: Name the specific API approach (Incoming Webhooks vs. Bot Token vs. OAuth) to avoid Claude picking one that does not match your needs.

16. The Form Builder

Prompt:

Create a multi-step onboarding form with 3 steps: (1) company info (name, size, industry dropdown), (2) team setup (invite up to 5 emails), (3) preferences (timezone, notification settings). Validate each step before allowing next. Persist progress to localStorage so users can resume. Use React Hook Form with Zod validation. Match the existing form styles in src/components/forms/.

When to use it: Complex multi-step forms with validation and state management.

Pro tip: Use SuperBuilder's plan mode for multi-step features. It will outline the implementation plan first, letting you course-correct before any code is written.

17. The Search Implementation

Prompt:

Add full-text search to the blog. Index the title, body, and tags fields of posts. Create a GET /api/search?q=query endpoint that returns ranked results with highlighted snippets. Use PostgreSQL's tsvector/tsquery for search. Add debounced search-as-you-type to the existing SearchBar component in src/components/SearchBar.tsx.

When to use it: Implementing search functionality with both backend and frontend components.

Pro tip: Specify the search technology (Postgres full-text, Elasticsearch, Meilisearch) explicitly. Each has very different implementation patterns.

18. The Authentication Flow

Prompt:

Add Google OAuth login alongside the existing email/password auth. Use the Authorization Code flow with PKCE. Create the OAuth callback handler at /api/auth/google/callback. If the Google email matches an existing account, link them. If not, create a new account. Store the Google ID in a new oauth_providers table. Keep the existing auth middleware unchanged.

When to use it: Adding an authentication method to an existing auth system.

Pro tip: Specify the exact OAuth flow (Authorization Code, PKCE, Implicit) and how to handle the existing-account-linking scenario. These are the two biggest sources of auth bugs.

19. The Real-Time Feature

Prompt:

Add real-time presence indicators to the document editor. Show which users are currently viewing or editing the document. Use WebSocket connections (we already have Socket.IO set up in src/ws/server.ts). Broadcast join/leave events. Show colored dots next to user avatars with a tooltip showing "Viewing" or "Editing". Clean up presence on disconnect and on 30-second heartbeat timeout.

When to use it: Building collaborative or real-time features on top of an existing WebSocket setup.

Pro tip: Always specify the cleanup/timeout behavior for real-time features. Without it, Claude will often skip disconnect handling.

20. The Background Job

Prompt:

Create a background job that generates monthly usage reports for all active organizations. For each org, query the events table for the past month, calculate total API calls, unique users, and peak concurrent sessions. Generate a PDF report using the existing PDFService and email it to org admins. Schedule it to run on the 1st of each month at 6 AM UTC. Use the existing BullMQ setup in src/jobs/.

When to use it: Scheduled or queued background work with multiple processing steps.

Pro tip: Include the schedule, the data sources, the output format, and the delivery method. Background jobs have more moving parts than they appear.

Refactoring Prompts (21-30)

Refactoring is tricky because the goal is to change structure without changing behavior. These prompts help Claude Code refactor safely.

21. The Extract-and-Reuse

Prompt:

The date formatting logic is duplicated in src/components/OrderList.tsx, src/components/InvoiceTable.tsx, and src/components/ActivityFeed.tsx. Extract it into a shared utility in src/utils/dates.ts and update all three components to use the shared version. Keep the exact same formatting behavior.

When to use it: You have spotted duplication and want to DRY it up.

Pro tip: Listing every file that contains the duplication prevents Claude from missing one. Use grep to find all occurrences first.

22. The Modularization Refactor

Prompt:

The file src/api/orders.ts is 1,200 lines and handles creation, validation, payment, fulfillment, and cancellation. Split it into separate modules: order-creation.ts, order-validation.ts, order-payment.ts, order-fulfillment.ts, and order-cancellation.ts. Keep the same public API by re-exporting from an index.ts file. Don't change any behavior.

When to use it: A file has grown too large and needs to be split into focused modules.

Pro tip: Specifying the exact module names and the re-export strategy prevents Claude from making different organizational choices than you intended.

23. The Pattern Migration

Prompt:

Migrate the user authentication from express-session to JWT tokens. Replace session-based middleware in src/middleware/auth.ts with JWT verification. Update the login endpoint to return access + refresh tokens. Add a token refresh endpoint. Keep the same request.user interface so downstream handlers don't need changes.

When to use it: Migrating from one pattern or library to another while preserving the API contract.

Pro tip: Use SuperBuilder's verify mode after this refactor. It will check that the migration is complete and no session references remain.

24. The Error Handling Overhaul

Prompt:

The API error handling is inconsistent. Some endpoints return { error: string }, others return { message: string, code: number }, and some throw unhandled exceptions. Create a centralized AppError class with status code, error code, and message. Add an Express error middleware that catches AppErrors and formats consistent responses. Refactor the 5 most critical endpoints in src/api/ to use the new pattern.

When to use it: Your error handling has grown organically and needs standardization.

Pro tip: Ask Claude to refactor a few endpoints first rather than all of them. Review the pattern, then do the rest in a follow-up prompt.

25. The Async/Await Conversion

Prompt:

Convert all callback-based database operations in src/db/queries/ to use async/await with try/catch error handling. There are 12 files using the callback pattern with db.query(sql, params, (err, results) => {}). Preserve the same error messages and return types. Update the calling code as needed.

When to use it: Modernizing callback-heavy code to async/await.

Pro tip: If you have tests, mention them so Claude runs them after each conversion to verify nothing broke.

26. The State Management Refactor

Prompt:

The dashboard page passes props through 6 levels of components (prop drilling). Refactor to use React Context for the dashboard state. Create a DashboardProvider with the current filters, date range, and selected metrics. Replace prop drilling with useContext hooks. Keep the component rendering behavior identical.

When to use it: Prop drilling has gotten out of hand and you want to introduce context or a state manager.

Pro tip: Mention the specific props being drilled so Claude knows exactly what to lift into context.

27. The Configuration Externalization

Prompt:

There are hardcoded values throughout the codebase: API URLs, timeout durations, retry counts, feature flags, and rate limits. Find all hardcoded configuration values in src/services/ and src/api/ and move them to a centralized config module at src/config/index.ts that reads from environment variables with sensible defaults.

When to use it: Hardcoded values are scattered across the codebase and need to be centralized.

Pro tip: Ask Claude to list all discovered hardcoded values before making changes so you can review which ones should actually be configurable.

28. The Type Safety Upgrade

Prompt:

The API response types are using `any` in 15+ places across src/hooks/ and src/api/client.ts. Replace every `any` with proper TypeScript types. Infer types from the API schemas in src/api/schemas/ where possible. Create new interface files in src/types/ for any response shapes that don't have types yet.

When to use it: Your codebase has type safety holes that need to be plugged.

Pro tip: Use SuperBuilder's verify mode after this change to confirm zero any types remain in the targeted files.

29. The Dependency Replacement

Prompt:

Replace moment.js with date-fns throughout the project. We use moment for: formatting dates, calculating relative time, parsing ISO strings, and timezone conversions. Find all moment imports, replace with equivalent date-fns functions, and remove moment from package.json. Run the existing tests to verify nothing broke.

When to use it: Replacing a heavy or deprecated dependency with a modern alternative.

Pro tip: Name the specific use cases of the old library so Claude knows which replacement functions to use. "Replace X with Y" alone is too vague.

30. The Architecture Layer Addition

Prompt:

Add a service layer between the API route handlers and the database queries. Currently, route handlers in src/api/ call database functions directly. Create service files in src/services/ that contain the business logic. Route handlers should only handle HTTP concerns (parsing request, sending response). Services handle validation, business rules, and data access. Start with the users and orders modules.

When to use it: Adding an architectural layer (service, repository, etc.) to improve separation of concerns.

Pro tip: Pick 2-3 modules to refactor first, review the pattern, then ask Claude to apply it to the rest. This prevents architectural drift.

Testing Prompts (31-35)

Testing prompts work best when you specify the testing framework, the scope, and the edge cases you care about.

31. The Unit Test Generator

Prompt:

Write unit tests for the PricingCalculator class in src/services/pricing.ts. Cover: basic price calculation, percentage discounts, fixed-amount discounts, discount stacking, tax calculation, currency rounding, zero-quantity edge case, and negative price validation. Use Jest. Mock the TaxService dependency.

When to use it: You need thorough unit test coverage for a specific module.

Pro tip: Listing the specific scenarios prevents Claude from only testing the happy path. Always include at least 3 edge cases in your prompt.

32. The Integration Test Builder

Prompt:

Write integration tests for the POST /api/orders endpoint. Test: successful order creation, insufficient inventory, invalid product ID, unauthenticated request, expired discount code, and concurrent order attempts for the last item in stock. Use supertest with a test database. Set up and tear down test data in beforeEach/afterEach.

When to use it: Testing an API endpoint with database interactions and multiple failure scenarios.

Pro tip: Mention the test database strategy (in-memory SQLite, Docker Postgres, test schema) so Claude sets up the fixtures correctly.

33. The Snapshot Test Creator

Prompt:

Add React Testing Library snapshot tests for all components in src/components/ui/. For each component, render it with default props and with all prop variants (sizes, colors, disabled state, loading state). Use @testing-library/react with Jest. Group tests by component.

When to use it: You want baseline visual regression coverage for a UI component library.

Pro tip: Snapshot tests are most useful for stable components. Skip them for components still in active development.

34. The Test Fixture Factory

Prompt:

Create test fixture factories in src/test/factories/ for: User, Team, Project, and Invoice. Each factory should generate realistic fake data using @faker-js/faker. Support overriding any field. Support creating related objects (e.g., createTeamWithMembers(count)). Include TypeScript types for all factory return values.

When to use it: You need reusable test data generators that produce realistic, typed fixtures.

Pro tip: This is a great prompt to run with SuperBuilder's plan mode -- it will design the factory API before implementing it.

35. The Edge Case Test Suite

Prompt:

The parseUserInput() function in src/utils/input-parser.ts handles free-text search queries. Write tests for: empty string, single character, 10,000 character input, SQL injection attempts, XSS payloads, Unicode characters (emoji, CJK, RTL), strings with only whitespace, and inputs with special regex characters. Use Jest. Each test should verify the function neither throws nor returns unsafe content.

When to use it: Hardening a public-facing input handler against malicious or unexpected input.

Pro tip: Security-related edge case tests are the highest-value tests you can write. Always include injection and encoding tests for user input handlers.

Documentation Prompts (36-40)

Good documentation prompts tell Claude who the audience is and what format to use.

36. The API Documentation Generator

Prompt:

Generate OpenAPI 3.0 documentation for all endpoints in src/api/v1/. Include: path, method, description, request body schema (from Zod schemas), response schemas for 200/400/401/404/500, and example request/response pairs. Output as a YAML file at docs/api/openapi.yaml.

When to use it: You need machine-readable API docs generated from your existing code.

Pro tip: Point Claude at your validation schemas (Zod, Joi, Yup) so it can generate accurate request/response types automatically.

37. The README Writer

Prompt:

Write a README.md for this project. Include: one-paragraph description, tech stack list, prerequisites, local development setup (step by step), environment variables table (from .env.example), available npm scripts, project structure overview (top-level directories only), contributing guidelines, and license. Keep the tone professional and concise.

When to use it: Starting a new project or overhauling a neglected README.

Pro tip: Mention "from .env.example" or similar source files so Claude generates accurate env variable documentation instead of guessing.

38. The Architecture Decision Record

Prompt:

Write an ADR (Architecture Decision Record) for our decision to migrate from REST to GraphQL for the mobile API. Context: mobile app makes 12+ requests per screen, REST over-fetching wastes bandwidth. Decision: GraphQL for mobile, keep REST for third-party integrations. Consequences: need to maintain two API layers, team needs GraphQL training. Use the standard ADR format (Title, Status, Context, Decision, Consequences).

When to use it: Documenting an architectural decision for future team members.

Pro tip: Give Claude the context, decision, and consequences -- it will structure the ADR properly. These documents are invaluable six months later.

39. The Code Comment Documenter

Prompt:

Add JSDoc comments to all exported functions and classes in src/services/billing.ts. Include: description, @param with types and descriptions, @returns with type and description, @throws for known error conditions, and @example with realistic usage. Don't change any code, only add documentation comments.

When to use it: You need to add inline documentation to a critical module.

Pro tip: "Don't change any code" is an important constraint. Without it, Claude might refactor while documenting.

40. The Runbook Creator

Prompt:

Create an incident runbook for "Database connection pool exhaustion" at docs/runbooks/db-pool-exhaustion.md. Include: symptoms (what alerts fire, what users see), diagnosis steps (which metrics to check, what queries to run), mitigation steps (ordered from least to most disruptive), root cause investigation checklist, and post-incident follow-up tasks. Write it for an on-call engineer who may not be familiar with this specific system.

When to use it: Creating operational documentation for known failure modes.

Pro tip: Specify the audience ("on-call engineer who may not be familiar") to set the right level of detail. Runbooks that assume too much knowledge are useless at 3 AM.

Code Review Prompts (41-45)

Claude Code makes an excellent automated reviewer when given the right focus areas.

41. The Security Audit

Prompt:

Review src/api/ for security vulnerabilities. Check for: SQL injection (even with ORM), XSS in server-rendered content, missing authentication on endpoints, overly permissive CORS, sensitive data in logs, insecure direct object references (IDOR), and missing rate limiting. Report findings with severity (critical/high/medium/low) and specific file:line references.

When to use it: You want a security-focused review of your API layer.

Pro tip: Use SuperBuilder's ask mode here. It will analyze and explain findings without modifying any code, which is exactly what you want for a review.

42. The Performance Review

Prompt:

Review the React components in src/components/Dashboard/ for performance issues. Check for: unnecessary re-renders, missing useMemo/useCallback, expensive calculations in render, large component trees that should be split, missing React.lazy for heavy components, and unoptimized list rendering. Suggest fixes for each issue found.

When to use it: Your UI is sluggish and you want a systematic performance audit.

Pro tip: If you have React DevTools profiler output, paste the summary. Quantitative data helps Claude prioritize the biggest wins.

43. The Accessibility Review

Prompt:

Audit the components in src/components/ui/ for WCAG 2.1 AA compliance. Check for: missing aria labels, insufficient color contrast, keyboard navigation support, focus management in modals/dropdowns, screen reader compatibility, missing alt text, and proper heading hierarchy. List violations with WCAG success criterion references.

When to use it: You need to ensure your UI components meet accessibility standards.

Pro tip: Ask Claude to fix critical violations in a follow-up prompt. Separating the audit from the fix gives you a chance to prioritize.

44. The Dependency Audit

Prompt:

Review package.json for: outdated dependencies with known security vulnerabilities, unused dependencies (not imported anywhere in src/), dependencies that should be devDependencies, duplicate packages that serve the same purpose, and excessively heavy packages with lighter alternatives. Output a prioritized action list.

When to use it: Periodic dependency hygiene review.

Pro tip: Run npm audit and paste the output alongside this prompt for a more comprehensive review.

45. The Code Quality Review

Prompt:

Review the last 5 commits on this branch for code quality issues. Check for: inconsistent naming conventions, functions longer than 50 lines, deeply nested conditionals (> 3 levels), magic numbers without named constants, error messages that don't help with debugging, and any patterns that deviate from the rest of the codebase. Be specific with file and line references.

When to use it: Pre-merge code quality check on a feature branch.

Pro tip: "Patterns that deviate from the rest of the codebase" is a powerful instruction -- it uses your existing codebase as the style reference.

DevOps Prompts (46-50)

DevOps prompts work best when you specify the platform, the existing setup, and the deployment target.

46. The CI Pipeline Builder

Prompt:

Create a GitHub Actions CI pipeline in .github/workflows/ci.yml. Steps: (1) checkout, (2) setup Node 20, (3) npm ci with cache, (4) TypeScript type check, (5) ESLint, (6) Jest unit tests with coverage, (7) build, (8) upload coverage to Codecov. Run on push to main and on all PRs. Fail fast. Add a matrix for Node 18 and 20.

When to use it: Setting up a new CI pipeline or overhauling an existing one.

Pro tip: List the exact steps in order. CI pipelines are sequential by nature, and the order matters for fast failure.

47. The Docker Optimization

Prompt:

Optimize the Dockerfile in the project root. Current image is 2.1GB. Use multi-stage build: build stage with full node image, production stage with node:20-alpine. Only copy package files first for layer caching. Prune devDependencies in production. Set NODE_ENV=production. Add .dockerignore for node_modules, .git, tests, and docs. Target final image under 200MB.

When to use it: Your Docker image is bloated and needs slimming down.

Pro tip: Include the current image size and target size. Concrete numbers give Claude a measurable goal.

48. The Infrastructure as Code

Prompt:

Create Terraform configuration for deploying this Node.js app to AWS. Resources: ECS Fargate cluster, ALB with HTTPS, RDS PostgreSQL (db.t3.micro), ElastiCache Redis, S3 bucket for uploads, CloudWatch log groups. Use separate files: main.tf, variables.tf, outputs.tf. Parameterize: region, instance sizes, database credentials. Add a terraform.tfvars.example.

When to use it: Setting up cloud infrastructure from scratch with IaC.

Pro tip: Always specify the cloud provider, service tier (Fargate vs EC2, RDS vs Aurora), and whether this is dev/staging/production. Cost implications vary dramatically.

49. The Monitoring Setup

Prompt:

Add application monitoring to the Express app. Implement: (1) request duration histogram middleware, (2) error rate counter by endpoint, (3) active connection gauge, (4) database query duration tracking, (5) /metrics endpoint in Prometheus exposition format. Use prom-client library. Don't add external services -- just expose the metrics endpoint for scraping.

When to use it: Adding observability to your application.

Pro tip: Specify "Prometheus format" or "StatsD" or "OpenTelemetry" upfront. The metric collection pattern is fundamentally different for each.

50. The Deployment Script

Prompt:

Create a deployment script at scripts/deploy.sh that: (1) runs all tests, (2) builds the production bundle, (3) creates a git tag with semantic version from package.json, (4) builds and pushes Docker image to ECR with version tag, (5) updates the ECS service with the new task definition, (6) waits for deployment to stabilize (5 min timeout), (7) rolls back if health check fails. Add --dry-run flag that prints commands without executing.

When to use it: Creating an automated deployment pipeline with rollback capability.

Pro tip: The --dry-run flag request is important. Deployment scripts without a dry-run mode are dangerous to iterate on.

SuperBuilder Execution Modes: Making Prompts 10x More Effective

Every prompt above works great in vanilla Claude Code. But with SuperBuilder, you can wrap any prompt in an execution mode that fundamentally changes how Claude approaches the task.

SuperBuilder offers five execution modes that wrap your prompt with specialized instructions:

Plan Mode: Think Before You Code

What it does: Wraps your prompt with instructions to analyze the codebase, outline a step-by-step implementation plan, and wait for your approval before writing any code.

Best for: Feature building prompts (11-20), architectural refactors (22, 30), and any task where you want to review the approach before committing to it.

Example: Sending prompt #16 (multi-step form) in plan mode produces a numbered implementation plan covering component structure, validation strategy, state management, and localStorage persistence -- before a single line of code is written.

When to use it: You are not sure about the implementation approach, or the task is complex enough that course-correcting mid-implementation would be expensive.

Debug Mode: Hypothesis-Driven Debugging

What it does: Transforms your bug report into a structured debugging session. Claude generates hypotheses about the root cause, ranks them by likelihood, and tests each one systematically with evidence.

Best for: Bug fixing prompts (1-10), especially race conditions (#5), silent failures (#3), and data corruption (#10).

Example: Sending prompt #5 (race condition) in debug mode produces:

• Hypothesis 1: Cache invalidation happens before DB write commits (likelihood: high)
• Hypothesis 2: Read replica lag returns stale data (likelihood: medium)
• Hypothesis 3: Browser cache serves stale response (likelihood: low)

Then Claude tests each hypothesis with targeted code analysis and evidence gathering.

When to use it: The bug is non-obvious and you want a systematic investigation rather than a guess-and-check approach.

Verify Mode: Check Your Work

What it does: After making changes, Claude re-reads all modified files and verifies the changes are correct, complete, and don't introduce new issues.

Best for: Refactoring prompts (21-30), dependency replacements (#29), and pattern migrations (#23).

Example: After running prompt #29 (replacing moment.js with date-fns), verify mode scans every file for remaining moment imports, checks that all date operations produce identical output, and validates that tests still pass.

When to use it: You just made sweeping changes and want confidence that nothing was missed.

Ask Mode: Explain Without Changing

What it does: Claude analyzes and explains without modifying any files. Pure analysis and recommendations.

Best for: Code review prompts (41-45), architecture understanding, and learning unfamiliar codebases.

Example: Sending prompt #41 (security audit) in ask mode produces a detailed vulnerability report with file references and severity ratings -- without touching any code.

When to use it: You want information and analysis, not code changes. Reviews, audits, and knowledge transfer.

Normal Mode: Just Do It

What it does: Standard Claude Code behavior. Reads files, makes changes, runs commands.

Best for: Everything else. Most of the 50 prompts work excellently in normal mode when the prompt itself is clear and specific.

Raw Prompt vs. SuperBuilder Debug Mode: A Real Comparison

To illustrate how execution modes change outcomes, here is the same bug investigated two different ways.

The Bug

Users report that profile updates sometimes "don't save." No errors in the UI. The API returns 200. But the next page load shows old data.

Raw Prompt (Normal Mode)

Profile updates aren't saving. The API returns 200 but the data reverts on refresh. Check src/api/profile.ts and src/cache/user-cache.ts.

What happens: Claude reads both files, spots that the cache TTL is 5 minutes, and suggests adding cache.invalidate(userId) after the database update. This might fix the issue -- or it might be one of several contributing factors.

SuperBuilder Debug Mode Prompt

The same prompt, but sent in debug mode. SuperBuilder wraps it with instructions to generate hypotheses and test them:

What happens:

1. Hypothesis generation:

   • H1: Cache not invalidated after write (high likelihood)
   • H2: Database transaction not committed before response (medium)
   • H3: CDN/proxy caching the GET response (medium)
   • H4: Optimistic UI update masking a failed write (low)

2. Evidence gathering for each hypothesis:

   • H1: Reads cache code, finds no invalidation call -- confirmed
   • H2: Reads DB code, finds the write uses a transaction but the response is sent inside the transaction callback -- also confirmed, this is a second bug
   • H3: Checks response headers, no Cache-Control headers set -- potential issue
   • H4: Reads frontend code, no optimistic updates -- ruled out

3. Fix: Addresses both root causes (cache invalidation AND moving the response outside the transaction commit), plus adds Cache-Control headers as a defensive measure.

The debug mode approach found a second bug that the raw prompt missed entirely. This is the difference between treating symptoms and finding root causes.

Claude Code Tips and Tricks

Beyond the specific prompts, here are general Claude Code tips and tricks that improve results across all categories:

1. Use File Paths as Context Anchors

Instead of describing where code lives, give exact paths:

• Bad: "The user service handles authentication"
• Good: "The auth logic in src/services/auth/login.ts (lines 45-80)"

2. Reference Existing Patterns

Claude Code produces more consistent code when you point it at an existing example:

Follow the same patterns used in src/api/users.ts for error handling, validation, and response formatting.

3. Set Explicit Constraints

Constraints prevent Claude from making unwanted changes:

Don't add new npm dependencies. Don't modify the database schema. Keep backward compatibility with the v1 API.

4. Chain Prompts for Complex Work

For large tasks, use multiple focused prompts:

1. Plan mode: "Design the architecture for a notification system"
2. Normal mode: "Implement the notification service based on the plan above"
3. Normal mode: "Add tests for the notification service"
4. Verify mode: "Review the notification system for edge cases and missing error handling"

5. Include Acceptance Criteria

Tell Claude what "done" looks like:

This is done when: (1) the migration runs without errors, (2) existing data is preserved, (3) the rollback migration restores the original schema, and (4) all existing tests pass.

6. Leverage SuperBuilder's Project Context

SuperBuilder maintains context across conversations within a project. Your CLAUDE.md file, file indexer, and conversation history mean Claude already knows your codebase. You can write shorter prompts because the context is already loaded.

7. Use the Right Mode for the Right Task

FAQ

What makes a good Claude Code prompt?

A good Claude Code prompt has four elements: (1) clear description of the problem or goal, (2) relevant file paths and context, (3) explicit constraints, and (4) a description of what success looks like. Vague prompts produce vague results.

How long should my Claude Code prompts be?

There is no ideal length -- clarity matters more than brevity. A 3-sentence prompt with exact file paths and constraints outperforms a 3-paragraph prompt full of background context Claude does not need. Include only information that changes the output.

Do these prompts work with other AI coding tools?

Most of these prompts work with any AI coding agent (Cursor, Copilot, Aider). However, the execution mode sections (plan, debug, verify, ask) are specific to SuperBuilder and how it wraps prompts for Claude Code.

What is the difference between plan mode and ask mode?

Plan mode produces an implementation plan that Claude will execute after your approval. Ask mode only analyzes and explains -- no code changes are made. Use plan mode when you want to build something. Use ask mode when you want to understand something.

How does debug mode work in SuperBuilder?

Debug mode wraps your prompt with instructions to generate ranked hypotheses about the root cause, gather evidence for each hypothesis, and fix only the confirmed issues. It is significantly more thorough than a standard "fix this bug" prompt because it systematically eliminates possible causes instead of jumping to the first plausible fix.

Can I combine execution modes?

Yes, and you should. A common workflow is: debug mode to investigate a bug, normal mode to implement the fix, and verify mode to confirm the fix is complete. SuperBuilder makes switching between modes a single click.

Are these prompts free to use?

The prompts themselves are free -- use them however you like. Claude Code requires an Anthropic API subscription. SuperBuilder provides the desktop app with execution modes, project management, and conversation history on top of Claude Code.
