Related PRs

I see there are two other open PRs for Kilo:

• feat: add kilo-acp #88 -- kilo-acp (uvx, third-party bridge adapter by @Kvadratni)
• Add Kilo Code agent and icon #92 -- kilo-code (npx via @kilocode/cli by @pedrogiroldo)

This PR (#100) takes the native binary approach, pointing directly to official Kilo GitHub releases. The binary distribution has the advantage of zero runtime dependencies (no Node.js required).

That said, the ACP schema supports multiple distribution methods in a single entry -- binary, npx, and uvx can coexist in the same agent.json. That would let ACP clients choose whichever method works best for the user's environment.

If it makes sense, we'd be happy to collaborate with @pedrogiroldo to combine our entries into one that offers both binary and npx distribution, giving clients the choice. Happy to hear what the maintainers prefer.
