Claude Code and Cursor are the two agents developers reach for most in 2026. They look similar on the surface — both use AI to help you write and review code — but they're built around completely different philosophies. Choosing between them (or knowing when to use which) depends on what kind of work you're doing.
The fundamental difference
Cursor is an IDE. It's a fork of VS Code with AI woven into the editing experience: tab completion, inline chat, a composer for multi-file edits. You stay in the editor. The AI is embedded in your workflow.
Claude Code is an agent. It runs in your terminal and operates autonomously across your entire codebase. It reads files, runs commands, edits code, and navigates your project without you directing each step.
The simplest way to put it: Cursor helps you write code faster. Claude Code handles tasks you'd otherwise have to do yourself.
When to use Cursor
Cursor is strongest for active coding sessions — when you're in the flow and want AI suggestions as you type.
| Scenario | Why Cursor wins |
|---|---|
| Writing new code from scratch | Tab completion and inline suggestions stay out of your way |
| Refactoring a specific function | Inline chat targets exactly the lines you select |
| Learning an unfamiliar codebase | Ctrl+K explanations appear inside the file you're reading |
| Quick edits with precise control | You see every change before it's applied |
Cursor's composer handles multi-file changes well for focused tasks — "update all API calls to use the new auth header" across a handful of files.
When to use Claude Code
Claude Code shines when the task is too big or complex to direct manually.
| Scenario | Why Claude Code wins |
|---|---|
| "Add a feature end-to-end" | Autonomously touches routes, components, tests, and docs |
| Debugging a bug you can't locate | Searches the codebase, traces call chains, identifies root cause |
| Code review across a PR | Reads every changed file and produces a structured review |
| Running a migration or refactor at scale | Executes commands, checks results, continues iterating |
Claude Code is particularly effective with skills. A skill like a security auditor or documentation generator runs automatically against your code — you don't have to describe the task each time.
The skills advantage
This is where MDSkill comes in. Claude Code skills extend what the agent can do without you re-explaining context.
Search for skills that match your workflow:
npx mdskill search "code review"
Install one:
npx mdskill add owner/repo/skill-name
Claude Code picks up the skill automatically. The next time you run a review, the agent follows the skill's procedure — security checks, output format, severity ratings — without you prompting for it.
Cursor doesn't have a native equivalent to skills. You can use system prompts in its Rules feature, but they're not versioned, not audited, and not shareable as first-class artifacts.
Speed and context
For short tasks (edit this function, explain this code), Cursor is faster — you're already in the editor and the AI responds in milliseconds.
For long tasks, Claude Code has a larger context window and works through problems autonomously. You can give it a complex task, switch away, and come back to a result.
Which should you use?
Most developers end up using both. A practical split:
- Cursor for active coding — greenfield work, small edits, quick explanations
- Claude Code for agentic tasks — reviews, audits, complex features, anything that requires reading many files
If you can only pick one: choose based on where you spend most of your time. If you live in VS Code and want AI suggestions while you type, Cursor. If your work involves orchestrating complex tasks across a codebase, Claude Code.
Comparing the skills ecosystem
Both tools can be extended, but the ecosystems differ:
| Claude Code | Cursor | |
|---|---|---|
| Extension format | SKILL.md — versioned, audited, shareable | Rules — text prompts, editor-local |
| Discovery | mdskill.dev directory | No central directory |
| Security audit | Yes — score on every skill | No |
| Team sharing | Commit .claude/skills/ to git | Manual copy |
MDSkill's directory indexes skills for Claude Code (and other agents including Cursor, Cline, and Copilot). You can browse by category or search from the terminal.
