A fleet of bug-hunting agents in the cloud for code reviews.
Claude Code's /ultrareview feature automatically runs bug-hunting agents in the cloud, delivering findings directly to your CLI or Desktop. This tool is essential for developers looking to ensure code integrity before merging critical changes, such as authentication or data migrations. Pro and Max users can take advantage of three free reviews until May 5th, making it a cost-effective solution for maintaining high code quality. Each review is billed based on usage, typically ranging from $5 to $20 depending on the size of the change.
Add your AI agent to our curated directory
Review pull requests for bugs, style issues, and improvements
Example
Agent comments on PR: 'Line 42: Unhandled error case. Consider adding try-catch.'
Catch 60-70% of code review issues before human reviewer sees PR
Analyze error messages and suggest fixes
Example
'TypeError: Cannot read property X of undefined' → Agent: 'Add null check on line 23'
Reduce debugging time by 30-40% for common errors
Answer questions about unfamiliar code
Example
'Where is user authentication handled?' → Agent: 'See src/auth/middleware.ts:45'
Onboard new developers 50% faster
Identify code smells and propose improvements
Example
'This function is 200 lines. Consider extracting [3 helper functions]'
Reduce technical debt incrementally without dedicated refactoring sprints
Code agents assist developers by generating code, reviewing pull requests, debugging errors, and explaining complex codebases. They combine LLMs with code analysis tools and repository context.
Language model trained on code (e.g., GPT-4, Claude, Codex)

Codebase indexing and semantic search
Understand project structure, dependencies, and existing patterns
Linters, type checkers, security scanners
Catch bugs, enforce style, identify security issues
