- Inline local `$ref` pointers and strip `$defs` and `definitions` from tool parameter schemas for Moonshot compatibility.
- Ensure tool parameter root objects declare an explicit `type: "object"`.
Closes: #5316
* feat(config): add fingerprint-profile to Claude keys and auth JSON
- Add FingerprintProfile to ClaudeKey configuration struct and normalizer
- Track fingerprint-profile in config diff
- Map fingerprint-profile / fingerprint_profile to auth attributes in file and config synthesizers
- Support fingerprint-profile in Management API PatchClaudeKey and normalization
- Add Claude billing attribution string manipulation utilities in internal/util
- Document fingerprint-profile options in config.example.yaml
* feat(claude): add fingerprint policy and request-local CLI identity
- Centralize Claude fingerprint policy resolution in claude_fingerprint_policy.go
- Support stable Claude CLI identity synthesis (UUIDv5 account_uuid and SHA-256 device_id)
seeded from API keys or stable OAuth IDs, keeping access tokens isolated
- Warn on unrecognized fingerprint-profile values
* feat(claude): apply CLI fingerprint to Messages and keep API keys caller-owned
- Wire centralized fingerprint policy into Claude and Kimi executors
- Keep first-party Anthropic API keys and delegated providers caller-owned by default
- Apply Claude Code CLI wire profile (betas, metadata, diagnostics, MCP aliases)
when fingerprint-profile=claude-code-cli is configured
- Strictly align CCH signing with native Claude Code 2.1.220: only first-party
api.anthropic.com and Vertex sign dynamic CCH; third-party gateways and Kimi
receive billing header without cch= to avoid prompt cache busting
- Respect caller-owned count_tokens bodies by default while aligning CLI shape on opt-in
- Fall back to CLIProxyAPI/<version> User-Agent when caller sends no UA in caller-owned mode
- Scope custom operator header overrides accurately in caller-owned mode
- Add comprehensive test coverage for policy resolution, gateway opt-in, Kimi, and token counting
- Introduce a shared `isUsableKimiReasoning` helper and constant for the placeholder string.
- Prevent tool-call normalization from propagating or reusing placeholder/empty reasoning content.
- Preserve and reuse the latest valid assistant reasoning when normalizing `reasoning_content` for tool messages.
Closes: #4899
- Merge buffered `tool_calls` into the latest mergeable assistant message instead of always appending a new one.
- Combine deferred reasoning segments across the same assistant turn, while ignoring `[reasoning unavailable]` placeholders.
- Reset merge state on role/tool-output boundaries to keep tool-call attachment behavior correct across turns.
Closes: #4676
- 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.
Closes#4418

- 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
