feat: api.kilo.ai/api support

[dzianisv]

Summary

This PR adds support for Kilo Code as a new AI provider in opencode, complete with device authentication and dynamic model discovery.
Changes
Authentication (src/cli/cmd/auth.ts)

• Added open import for browser automation
• Implemented complete Kilo Code authentication flow using device code verification
• Added spinner UI for better UX during auth process
• Handles authorization approval, denial, expiration, and timeouts
• Integrated Kilo Code as priority level 7 in provider selection
  Model Discovery (src/provider/models.ts)
• Added Kilo Code provider configuration with Claude 3.5 Sonnet as default model
• Implemented dynamic model discovery via Kilo Code API
• Added local caching mechanism for models to improve performance
• Graceful fallback to cached models if API is unavailable
• Automatic background refresh of model list
  Provider Integration (src/provider/provider.ts)
• Added Kilo Code provider configuration using OpenAI-compatible SDK
• Configured proper headers and user agent for API requests
• Added proper model merging logic with cost, limit, and options handling
  Configuration (sst.config.ts)
• Updated SST config syntax from CommonJS to ES modules
• Standardized import statements and semicolon usage
  Technical Details
• Authentication: OAuth2 device code flow with 5-minute timeout
• Model Caching: Stored in ~/.cache/opencode/kilocode-models.json
• API Integration: Uses Kilo Code's OpenRouter-compatible endpoints
• Error Handling: Comprehensive error handling for network issues and auth failures
  Testing
  The implementation includes proper error handling and fallback mechanisms. The device code flow supports the full OAuth2 standard with support for approval, denial, expiration, and timeout scenarios.
  Breaking Changes
  None. This is an additive feature that doesn't modify existing functionality.

This would have been nice to have, but kilo code blocked it. They only allow on their plugins or cli, so they might block you if you try.

Would be cool if they add this!

I saw somewhere that Kilo added support for Moltbot. So I think it's safe to say you can use their gateway :)

Why don't you try it and let us know? Just don't use your main account.

I reached out to the Kilo team to clarify the Kilo Gateway TOS situation. Here's their response:

Hi, Alexandre
I'm Ligia from Customer Experience. Nice to meet you.
Yes, this is a change in our terms of service, and we are now offering our gateway to be used outside Kilo Code.
Thanks!
Best,
Ligia

Kilo has also migrated their cli to an OpenCode fork, which should significantly simplify integrating the Kilo Gateway into upstream OpenCode. See: https://github.com/kilo-Org/kilo

Let me know if you need any help with the integration, @dzianisv! 👍

I used a different approach by directly integrating the package from Kilo: #13863

Thanks @micuintus!
I also saw #13765 which looks like a great approach! It'll be interesting to see which solution the maintainers prefer 🙂
