19 Specialist Agents
Nine slash commands that supercharge your development workflow with AI-powered coding, testing, debugging, reviewing, and planning.
Powered by Copilot
Describe what you want, and AI Captain writes the code. Changes are automatically reviewed and refined until they pass quality checks.
@aicaptain /code
Expert Review
Get instant, expert-level code reviews. Finds bugs, security issues (OWASP), performance problems, and suggests best practices.
@aicaptain /review
Test Writer
Detects your test framework, matches existing patterns, and generates unit, integration, and e2e tests that actually run.
@aicaptain /test
Debug Agent
Reads errors, traces call chains, identifies root causes, and proposes minimal fixes. Analysis-first approach.
@aicaptain /debugAI Captain orchestrates 19 specialist agents to handle every phase of your development workflow.

Test, review, fix
Type your request in Copilot Chat or the Activity Bar sidebar. AI Captain detects your intent automatically.
Using your workspace context, Copilot generates precise search-replace edits and applies them to your files.
19 specialist agents handle testing, debugging, security auditing, code review, refactoring, and more — each optimized for its domain.
If critical issues are found, AI Captain fixes them automatically. The loop continues until the code passes review.
Activity Bar Sidebar
Click the AI Captain icon in the Activity Bar to open a standalone chat interface. No need to open Copilot Chat — code, review, research, and plan from a focused sidebar.

Expert Review
Unlike traditional linters, AI Captain's reviews check correctness, security (OWASP), types, architecture, performance, and style with a structured checklist.
AI Captain is completely free and open source. Just bring your GitHub Copilot subscription.

All 19 agents, all 9 commands
You need VS Code 1.99 or later and the GitHub Copilot Chat extension. That's it!
Yes! AI Captain is completely free and open source under the MIT license. The extension itself has zero cost. You just need a GitHub Copilot subscription (which you may already have).
AI Captain adds three key capabilities: (1) an autonomous coding loop that automatically applies and reviews code changes, (2) 19 specialist agents for testing, debugging, security auditing, refactoring, and more, and (3) a persistent memory bank that remembers decisions and patterns across sessions.
AI Captain works with any language or framework that GitHub Copilot supports — TypeScript, JavaScript, Python, Go, Rust, Java, C#, and many more. The /research command can look up documentation for any technology.
Code is processed through GitHub Copilot (which you're already using). No code is stored by AI Captain itself — it's a zero-dependency extension with no backend or telemetry.
AI Captain includes agents for coding, testing, debugging, security auditing, code review, pre-commit review, refactoring, migration, docs writing, rapid MVP building, production readiness validation, orchestrating multi-agent pipelines, full-stack development, architecture analysis, performance optimization, planning, TDD guidance, build fixing, and tech stack analysis. Install them with the "Install Agents" command.
Install AI Captain in 30 seconds and transform your VS Code into an autonomous coding powerhouse.
