- Added `CountClaudeInputTokens` for estimating token usage with O200kBase tokenizer.
- Enhanced `ClaudeExecutor` to handle token counting locally, reducing dependency on upstream services.
- Introduced validation for token count requests for improved error handling.
- Updated tests to cover local token counting behavior and invalid request handling.
Closes: #4103
- Updated Kimi executor to delegate non-streaming and streaming Claude requests to the Claude executor when `SourceFormat` is `claude`.
- Injected `base_url` for Claude API compatibility during delegation.
- Updated Kimi executor to route all Claude requests through the OpenAI-compatible chat completions API.
- Removed legacy delegation to Claude executor for non-streaming and streaming execution.
- Enhanced translator integration for request normalization and Kimi model stripping.
- Updated tests to validate chat completions behavior, including upstream request logging, payload transformation, and response handling.
- Deleted Kimi K3[1M] variant and associated metadata.
Claude Code sends the configured model name (e.g. kimi-k3[1m]) to
CLIProxyAPI. The Kimi executor forwarded this internal ID to Kimi's
https://api.kimi.com/coding endpoint. Kimi treats kimi-k3 and
kimi-k3[1m] as 256K-context models, while only bare k3 supports the
full 1M context window.
Normalize the upstream model by stripping the CLIProxyAPI kimi- prefix
and any Claude Code [1m] suffix while preserving a trailing thinking
suffix (e.g. (1024)), so that requests for kimi-k3, kimi-k3[1m],
kimi-k3(1024), and kimi-k3[1m](1024) are all sent to Kimi as k3 or
k3(1024). This applies to:
- Execute (Claude and OpenAI branches)
- ExecuteStream (Claude and OpenAI branches)
- CountTokens
Validation (using the stored Kimi token):
- GET /v1/models shows k3 with context_length 1048576.
- Direct /v1/messages calls with ~270k input tokens:
- model=k3 succeeds.
- model=k3[1m], kimi-k3, kimi-k3[1m] fail with:
'Your request exceeded model token limit: 262144 (requested: 270014)'.
Add unit tests for normalizeKimiUpstreamModel.

- Added an `incomingHeaders` argument to `applyClaudeHeaders` to enable external header injection for flexibility.
- Updated Kimi executor to delegate header support to Claude executor, facilitating upstream request logging and beta header forwarding.
- Introduced tests for delegated configuration, header handling, and upstream request/response logging to improve coverage.
- Added `filterKimiEmptyAssistantMessages` to identify and remove empty assistant messages with no content, tool links, or reasoning.
- Integrated logging to track the number of dropped messages.
- Updated tests to validate the filtering logic for both empty and valid assistant messages.
Fixed: #1730
