The featured Anthropic-compatible provider presets now advertise their Sonnet models as one-million-token windows so the desktop context form and runtime env match the requested provider limits. Regression assertions cover both preset display and runtime env generation.
Constraint: Only the two featured provider presets requested by the desktop settings flow should change.
Rejected: Change global Sonnet built-in default | would alter unrelated providers and custom models.
Confidence: high
Scope-risk: narrow
Directive: Do not lower these preset windows without checking provider-specific limits and the desktop settings preview.
Tested: bun test src/server/__tests__/provider-presets.test.ts src/server/__tests__/providers.test.ts
Tested: bun run check:server
Tested: agent-browser UI verification on http://127.0.0.1:49174 with backend http://127.0.0.1:49173
Not-tested: Live API requests against 接口AI or 胜算云.
Provider presets now carry an explicit auth strategy so Anthropic-compatible services can choose the right Claude Code environment shape instead of relying on one global variable. The desktop editor exposes the same strategy, keeps settings.json previews in sync, and applies the strategy to connection tests as well as runtime env sync.
Constraint: Third-party Anthropic-compatible providers do not agree on ANTHROPIC_API_KEY versus ANTHROPIC_AUTH_TOKEN.
Rejected: Force all third-party providers onto one env var | breaks providers that require bearer auth, dual variables, or dummy local auth.
Confidence: high
Scope-risk: moderate
Directive: Add new provider presets with explicit authStrategy; do not infer auth behavior from model names alone.

Not-tested: Live successful calls for every third-party provider with real credentials.
Teach provider presets and saved providers to carry per-model context windows so auto-compact uses provider-specific limits instead of a blanket fallback. The desktop provider form now keeps these limits in an advanced context section and syncs the generated settings preview with model changes.
Constraint: Third-party provider APIs do not consistently expose machine-readable model context windows.
Rejected: Keep a single 100K/200K fallback | modern provider windows vary from 128K to 1M+ and the fallback caused late or early compaction.
Confidence: high
Scope-risk: moderate
Directive: Do not change provider compact thresholds without re-running real provider long-context checks.
Tested: bun test src/services/compact/autoCompact.test.ts; bun test src/server/__tests__/provider-presets.test.ts src/server/__tests__/providers.test.ts src/server/__tests__/providers-real.test.ts; bun run check:server; bun run check:desktop; bun run check:policy; bun run check:native; MiniMax/Kimi/DeepSeek live long-context probes; agent-browser provider form flow.
Not-tested: quality:pr policy gate still requires explicit allow-cli-core-change for CLI core edits.
Desktop users can now disable thinking for new sessions, and Anthropic-compatible providers that opt in receive explicit disabled-thinking requests across main turns, side queries, and AI title generation.
Constraint: DeepSeek/Kimi/GLM Anthropic-compatible endpoints need a non-thinking path without scattering provider-specific logic through the CLI.
Rejected: Per-model if/else branches | centralized provider preset env keeps the native CLI surface smaller and easier to audit.

Default desktop sessions with an active third-party provider were only passing the selected model into the CLI startup path. That allowed the child CLI to fall back to stale cc-haha settings env instead of the provider index, so the UI-selected provider could diverge from the key and endpoint used by the subprocess.
Route default sessions through the active provider id and make third-party Sonnet capability overrides explicit with a non-empty sentinel. This keeps provider runtime env sourced from providers.json and avoids treating third-party Sonnet models as first-party thinking-capable models.
Constraint: Third-party provider behavior is the product baseline for desktop users.
Rejected: Rely on synced cc-haha/settings.json env | it can be stale and caused provider/key routing mismatches.
Confidence: high
Scope-risk: narrow
Directive: Third-party desktop sessions must carry providerId into ConversationService; do not depend on global settings env for active providers.
Tested: bun test src/server/__tests__/conversations.test.ts src/server/__tests__/conversation-service.test.ts src/server/__tests__/provider-presets.test.ts src/utils/__tests__/thinking.test.ts
Tested: git diff --check
Third-party Anthropic-compatible providers can expose Claude model names without supporting every first-party runtime capability. Desktop sessions now preserve provider-specific capability overrides, keep selected provider runtime state across reconnects and restarts, and keep the provider dialog behavior aligned with the updated presets.
Constraint: Custom ANTHROPIC_BASE_URL endpoints must not be treated as first-party Anthropic for adaptive thinking support.
Rejected: Rename provider default Sonnet models | that would hide the compatibility issue instead of fixing runtime capability detection.
Confidence: high
Scope-risk: moderate
Directive: Do not enable Claude first-party capability defaults for custom Anthropic-compatible base URLs without provider verification.

Provider setup now keeps API keys hidden by default while still allowing an explicit reveal, and the About page links users directly to release notes and issue feedback. Provider preset copy was also adjusted so promotional text stays intentional and current.
Constraint: Reuse the existing settings page structure and provider preset schema
Confidence: high
Scope-risk: moderate
Reversibility: clean
Tested: cd desktop && bun run test -- generalSettings.test.tsx
Not-tested: Full desktop lint and production build
Provider setup now carries the metadata needed for sponsored and local Anthropic-compatible providers, while keeping provider URLs and API keys editable in the desktop form. The desktop UI also exposes API-key links, optional sponsor copy, full key visibility, and local no-key presets that can be activated into runtime settings.
Constraint: Local LM Studio and Ollama integrations require Anthropic-compatible root URLs rather than OpenAI /v1 URLs
Rejected: Keep local providers at the top of the preset list | user requested them immediately before Custom
Confidence: high
Scope-risk: moderate
Directive: Do not change local provider base URLs to /v1 without rechecking Anthropic compatibility docs
Tested: bun test src/server/__tests__/provider-presets.test.ts src/server/__tests__/providers.test.ts

Kimi Code documents a separate Anthropic-compatible coding endpoint from the Moonshot open platform, so the built-in Kimi preset should point Claude-compatible traffic at the coding endpoint instead of the retired Moonshot anthropic path.
Constraint: Kimi Code Anthropic-compatible base URL is https://api.kimi.com/coding/ and this app appends /v1/messages at runtime.
Rejected: Use https://api.moonshot.cn/coding | official Kimi docs distinguish Kimi Code from the Moonshot open platform URLs.
Confidence: high
Scope-risk: narrow
Directive: Do not switch Kimi back to api.moonshot.cn/anthropic without rechecking current Kimi Code docs.
Tested: bun test src/server/__tests__/provider-presets.test.ts
Not-tested: Live Kimi API call with a real user key
The provider picker had two separate preset definitions and some defaults had
started to drift from the model IDs vendors document for Claude Code /
Anthropic-compatible usage. This change moves built-in presets to one
server-side JSON source, serves that source through the existing presets API,
and makes the desktop settings page consume the API instead of a duplicated
frontend constant. The preset defaults were then corrected against vendor docs
so the built-in values match documented model IDs and casing.
Constraint: Built-in provider defaults must match official vendor Claude Code or Anthropic docs
Rejected: Keep duplicated frontend and backend preset lists | values and casing drifted independently
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Update src/server/config/providerPresets.json and rerun provider-presets tests before changing built-in provider defaults again
Tested: bun test src/server/__tests__/provider-presets.test.ts; cd desktop && bun run lint
Not-tested: Manual desktop settings UI interaction after fetching presets from the API
Add a protocol-translating reverse proxy that allows using OpenAI-compatible
API providers (DeepSeek, OpenRouter, Groq, etc.) with Claude Code.
The proxy intercepts Anthropic Messages API requests from the CLI, transforms
them to OpenAI Chat Completions or Responses API format, forwards to the
upstream provider, and transforms streaming/non-streaming responses back.
Key features:
- Request transform: Anthropic Messages → OpenAI Chat/Responses
- Response transform: OpenAI → Anthropic (streaming SSE + non-streaming)
- Provider-agnostic reasoning support (reasoning_content, thinking_blocks,
reasoning fields from DeepSeek, OpenAI o-series, GLM-5, Groq, etc.)
- Event queue pattern for correct Anthropic SSE event ordering
- Two-step test: ① connectivity check ② full proxy pipeline validation
- Desktop UI: API format selector, two-step test results display
