Add Kiro language model SDK with converters, streaming, tokenizer, provider factory, and model resolver for AWS CodeWhisperer integration.
Add Kiro plugin with Builder ID SSO authentication flow, token refresh, and register it in the plugin index. Add @anthropic-ai/sdk dependency.
Register Kiro in provider database with models: claude-sonnet-4-5, claude-opus-4-5, claude-opus-4-6, claude-sonnet-4-6, claude-haiku-4-5, claude-sonnet-4, claude-3-7-sonnet. Add @ai-sdk/kiro reasoning variants to transform.
Add Kiro model ID fallback in agent resolution and extend message-v2 for Kiro provider compatibility.
Add tests for Kiro provider registration, model definitions, tool pairing, compaction, overflow recovery, and plugin auth flow.
Remove tests that depend on compaction functions (shouldCompact, fitMessages, truncateModelMessages, aggressive mode) not present in dev baseline. Fix kiro-provider context limit assertion (210K -> 200K).

The following comment was made by an LLM, it may be inaccurate: Potential duplicate found:
This PR appears to be an earlier attempt at adding Kiro provider support. The current PR #18408 is likely an updated/improved implementation with the @ai-sdk/kiro SDK, suggesting the previous PR may have been closed or superseded. |

Type of change
What does this PR do?
Adds Kiro as a provider in OpenCode. Kiro uses AWS CodeWhisperer-backed Claude models via Builder ID SSO auth.
Changes:
@ai-sdk/kiroSDK undersrc/provider/kiro/(converters, streaming, tokenizer, language model, provider factory)src/plugin/kiro.ts) handling Builder ID SSO auth + token refreshtransform.tsBuilt on top of work from:
Two main gotchas with Kiro's API: context window is ~200K tokens (exceeding it causes rejection), and there's no official docs on the exact request payload format — the opencode-kiro-auth repo was essential for figuring that out.
Thanks to both authors for their work 🙏 This is a baseline implementation — some edge cases may not be fully covered, so feedback is welcome.
