Desktop failures were previously hard to debug from issue reports because server-side and CLI startup details were only partially visible in the UI. This adds a dedicated cc-haha diagnostics store with sanitized structured events, runtime error summaries, a Settings diagnostics view, and an exportable bundle that users can attach to reports.
Constraint: Diagnostic exports must not include chat content, file contents, full environment variables, API keys, bearer tokens, cookies, or OAuth tokens.
Rejected: Export raw server logs | easier to debug but too likely to leak secrets and private workspace data.
Rejected: Keep diagnostics only in transient UI errors | still leaves maintainers unable to diagnose later GitHub issues.
Confidence: high
Scope-risk: moderate
Directive: Do not add raw transcript, prompt, attachment, or environment dumps to diagnostics without a separate privacy review.

Tested: cd desktop && bun run test src/__tests__/diagnosticsSettings.test.tsx --run
Tested: cd desktop && bun run lint
Tested: cd desktop && bun run build
Tested: agent-browser E2E on local server/dev UI for CLI startup failure, provider test failure, diagnostics tab, copy summary, export bundle, and tar/secret scan
Not-tested: Destructive clear-logs button in browser E2E; local deletion was intentionally not clicked.
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
Tested: cd desktop && bun run lint
Tested: cd desktop && bun run test src/__tests__/generalSettings.test.tsx --run
Tested: git diff --cached --check
Tested: Web UI provider creation plus real sessions for LM Studio, Ollama, JiekouAI, and Shengsuanyun
Not-tested: Production packaged Tauri build
The desktop provider flow was still mixing provider-managed state with
`~/.claude/settings.json`, which let unrelated tools leak fields like
`ANTHROPIC_REASONING_MODEL` and `model` back into the active provider path.
This change moves the provider JSON editor onto `~/.claude/cc-haha/settings.json`,
routes provider settings through dedicated `/api/providers/settings` endpoints,
and makes model reads/writes under an active provider use the managed cc-haha
settings instead of the global user settings file.
Constraint: Active provider model selection must be isolated from legacy ~/.claude/settings.json
Rejected: Keep merging provider JSON with settingsApi.getUser() | external tools can reintroduce unrelated model fields into the provider flow
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Any future provider-model UI or runtime change should read/write cc-haha managed settings first, not the global user settings file
Tested: bun test src/server/__tests__/provider-presets.test.ts src/server/__tests__/settings.test.ts; cd desktop && bun run lint
Not-tested: Manual desktop provider modal interaction after the cc-haha settings API switch
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

Implement a full Provider management layer compatible with Claude Code's settings.json protocol.
- ProviderService: CRUD + activation + settings.json sync + HTTP connectivity test
- Provider REST API: 8 endpoints (list, get, create, update, delete, activate, test)
- API key masking in GET responses (sk-a****xyz)
- Models API refactored to read from active Provider dynamically
- 42 unit tests + 6 real-config integration tests, all passing
