AI Coding Prompts for Developers & Programmers

Select a category or browse all coding prompts below

1. Bug Fix & Optimization

4. REST API Development

GENERATE

Create secure and scalable APIs.

Create a REST API for [resource] using [framework] with CRUD, auth, validation, pagination, Swagger docs, tests, and examples.

5. Unit & Integration Tests

TEST

Create reliable automated tests.

Write unit and integration tests for this [language/framework] code including success, failure, edge cases, mocks, and coverage tips.

6. Security Audit

SECURITY

Find and fix vulnerabilities.

Audit this [language] code for security issues like XSS, SQL injection, auth flaws, and insecure configs. Provide fixes.

7. Performance Optimization

OPTIMIZE

Improve speed and scalability.

Optimize this [language] code focusing on algorithms, memory usage, DB queries, caching, and scalability.

8. System Architecture Design

ARCHITECT

Design scalable systems.

Design a scalable system architecture for [application] including tech stack, data flow, APIs, security, and scalability.

9. DevOps & Deployment

DEVOPS

Automate build and deployment.

Create a CI/CD pipeline for [app] using [tool] including build, test, deploy, env vars, rollback.

10. Algorithm Design

GENERATE

Design efficient algorithms.

Design an optimal algorithm to solve [problem] and explain logic, complexity, edge cases, and alternatives.

11. Spec-Driven Feature Specification (SDD)

ARCHITECT

Write the executable spec first so a coding agent implements it correctly instead of guessing intent.

Write a spec-driven development (SDD) specification for [feature/system] before any code is written. Include the exact problem statement, explicit acceptance criteria in EARS-style notation ("the system shall..."), data model and API contract, edge cases and error states, out-of-scope items to prevent scope drift, and a definition of "done" an AI coding agent can verify itself against. Treat this spec as the source of truth the agent implements from, not a suggestion it can improvise around.

12. Context Engineering Setup for AI Coding Agents

ARCHITECT

Build the persistent project-context file that keeps a coding agent aligned across a large codebase.

Create a persistent context file (like CLAUDE.md or AGENTS.md) for this [language/framework] project. Include project structure and key file locations, coding conventions and naming rules, architectural decisions the agent must respect, dependencies and how to run tests, common pitfalls previous agent sessions have hit, and instructions for what the agent should do when it's uncertain rather than guessing. Keep it concise enough to fit in context every session while covering what actually causes agents to drift.

13. LLM API Cost & Token Usage Optimization

OPTIMIZE

Cut LLM spend in an AI-feature codebase without degrading output quality.

Audit this [application]'s LLM API usage and optimize for cost. Identify redundant or oversized prompts, opportunities for prompt caching, places a smaller/cheaper model would perform just as well, batching opportunities for non-latency-sensitive calls, and a token-budget monitoring approach so cost regressions are caught automatically. Estimate the cost impact of each change before recommending it.

14. Autonomous Debugging Loop with Verification

DEBUG

Set up a debugging workflow where the agent reproduces, fixes, and verifies its own fix before reporting done.

Debug this [language/framework] issue using a verify-before-done loop. First reproduce the bug with a minimal failing test case, form a hypothesis about the root cause and state it explicitly before changing code, apply the smallest fix that addresses the root cause rather than the symptom, re-run the failing test plus the full existing test suite to confirm nothing else broke, and only report the issue resolved once the verification step actually passes.

15. AI Agent Tool-Use Security Guardrails

SECURITY

Define what an autonomous coding/ops agent is and isn't allowed to touch before giving it real tool access.

Design security guardrails for an AI agent with tool access (file system, APIs, database, deployment) in [environment]. Define an explicit allow-list of actions the agent can take without approval, a separate list requiring human confirmation (deletes, deploys, spending money, sending external messages), sandboxing/least-privilege scope for credentials the agent uses, logging so every agent action is auditable after the fact, and a kill-switch or rollback plan if the agent takes an unintended action.

16. Agentic CI/CD Pipeline with Automated PR Review

DEVOPS

A CI/CD pipeline where an agent reviews and verifies every PR against its spec before a human looks at it.

Design a CI/CD pipeline for [project] with an agentic review stage. Include the standard build/test/deploy steps, an added stage where an AI agent checks the PR diff against its originating spec/ticket for completeness, automatic flags for missing tests, undocumented breaking changes, or scope creep beyond the spec, a human-approval gate before anything reaches production, and a feedback loop so recurring agent-review mistakes get added back into the project's context file.

17. Agent-Augmented Code Review

REVIEW

Senior-level review, now including the specific failure modes agentic coding introduces.

Review this [language] code as a senior developer, with extra attention to AI-agent-generated code patterns. Highlight code quality issues, bugs, and performance problems, security risks, unnecessary complexity an agent may have added to "look thorough," any silent divergence from the original spec or ticket, missing test coverage for edge cases an agent typically skips, and clear, constructive improvement suggestions.

18. Executable Spec to Clean Architecture Refactor

ARCHITECT

Refactor toward clean architecture using a spec as the contract that verifies the refactor didn't change behavior.

Refactor this [language/framework] project to Clean Architecture, anchored to an explicit behavior spec. First write a short spec capturing the current external behavior that must not change, explain layer separation, dependency rules, and the new folder structure, provide updated code examples for the layers most affected, and verify against the spec at the end to confirm the refactor preserved behavior rather than silently changing it.

19. Cross-Language Migration with Agent Verification

GENERATE

Translate code across languages with a built-in check that behavior actually matches afterward.

Convert this [source language] code to [target language]. Ensure identical functionality and idiomatic syntax in the target language, optimized performance and proper error handling, comments explaining any behavior differences forced by language constraints, a small set of equivalent test cases run against both versions, and a note flagging anything you could not verify behaves identically.

20. MCP-Integrated SaaS Backend Template

GENERATE

SaaS backend foundation built to expose and consume tools over MCP for AI-native features.

Generate a SaaS-ready backend using [language/framework] with native MCP (Model Context Protocol) support. Include authentication, multi-tenancy, and role-based access, billing-ready subscription structure, an MCP server exposing the app's core actions as agent-callable tools, scoped, least-privilege permissions for what any connected AI agent can call, API documentation, environment configuration, and SaaS security best practices.
