Apply code review feedback from gemini-code-assist:
- Define default messages as local constants to improve maintainability
- Avoid magic strings in the empty content handling logic
Problem:
- OpenCode's /compaction command and auto-compaction (at 80%+ context)
sends requests that can result in empty assistant message content
- Kiro API strictly requires non-empty content for all messages
- This causes 'Bad Request: Improperly formed request' errors
- After compaction failure, the malformed message stays in history,
breaking all subsequent requests in the session
Solution:
- Add fallback content for empty assistant messages in
buildAssistantMessageFromOpenAI()
- Add history truncation (max 50 messages) to prevent oversized requests
- This ensures all messages have valid content before sending to Kiro API
Fixes issues with:
- /compaction command returning Bad Request
- Auto-compaction breaking sessions
- Conversations becoming unresponsive after compaction failure
Introduce `Filter` rules in the payload configuration to remove specified JSON paths from the payload. Update related helper functions and add examples to `config.example.yaml`.
- Add ErrorLogsMaxFiles config field with default value 10
- Support hot-reload via config file changes
- Add Management API: GET/PUT/PATCH /v0/management/error-logs-max-files
- Maintain SDK backward compatibility with NewFileRequestLogger (3 params)
- Add NewFileRequestLoggerWithOptions for custom error log retention
When request logging is disabled, forced error logs are retained up to
the configured limit. Set to 0 to disable cleanup.
Kiro API endpoints only exist in us-east-1, but OIDC region can vary
by Enterprise user location (e.g., ap-northeast-2 for Korean users).
Previously, when ProfileARN was not available, the code fell back to
using OIDC region for API calls, causing DNS resolution failures:
lookup codewhisperer.ap-northeast-2.amazonaws.com: no such host
This fix removes the OIDC region fallback for API endpoints.
The region priority is now:
1. api_region (explicit override)
2. ProfileARN region
3. us-east-1 (default)
Fixes: Issue #253 (200-400x slower response times due to DNS failures)
Switch from CodeWhisperer endpoint to Amazon Q endpoint for all auth types:
- Use q.{region}.amazonaws.com/generateAssistantResponse as primary endpoint
- Works universally across all AWS regions (CodeWhisperer only exists in us-east-1)
- Use application/json Content-Type instead of application/x-amz-json-1.0
- Remove X-Amz-Target header for Q endpoint (not required)
- Add x-amzn-kiro-agent-mode: vibe header
- Add x-amzn-codewhisperer-optout: true header
- Keep CodeWhisperer endpoint as fallback for compatibility
This change aligns with Amazon's consolidation of services under the Q branding
and provides better multi-region support for Enterprise/IDC users.
