- Expanded web search and fetching providers with robust parsing, authentication storage integration, and response validation.
- Added support for new configurations including SearXNG safesearch, Cloudflare AI Gateway endpoints, and dynamic Firecrawl base URLs.
- Implemented comprehensive test suites covering error handling, content filtering, and provider-specific response behaviors.
- Implemented a structured web-search query parsing module supporting directives, tokenization, date parsing, and syntax serialization.
- Updated search providers to map query directives and date bounds to native provider parameters and filters.
- Added lenient result constraint post-filtering and configuration settings for enhanced engine routing.
- Added comprehensive unit and integration tests covering query parsing, constraint filtering, and provider-specific request mapping.
The consumer ask endpoint (/rest/sse/perplexity_ask) intermittently closes
its socket before responding. getApiConfigs emitted the OAuth session JWT
(returned by getApiKey while OAuth is the active origin) as a direct
api.perplexity.ai api-key config, so a transient transport failure on the
ask endpoint fell through and sent the session token as a Bearer to the
direct API, whose 401 masked the real error.
- Suppress the direct api-key config when getCredentialOrigin reports the
active perplexity credential as oauth.
- Give the OAuth ask request one transport-only retry; HTTP responses
(including 401/429) are final and never retried.
- Add regression coverage for both legs.
Fixes#5315
- Added explicit existence checks for objects prior to property access across various test suites.
- Replaced optional chaining with non-null assertions to satisfy TypeScript strictness requirements in test assertions.
PerplexityProvider.isAvailable() accepted authStorage.hasAuth("openrouter")
as a valid credential, so any user with an OpenRouter key configured (for
LLM access) had every webSearch: auto request silently routed through
OpenRouter's perplexity/sonar-pro endpoint. Since Perplexity sits first in
SEARCH_PROVIDER_ORDER, downstream providers like Gemini were never reached
and users saw unexpected charges on their OpenRouter billing.
Auto-chain admission now requires a direct Perplexity credential
(PERPLEXITY_COOKIES, Perplexity OAuth, or PERPLEXITY_API_KEY).
isExplicitlyAvailable still returns true, so users who want the
OpenRouter-backed perplexity/sonar-pro path can opt in by setting
webSearch: perplexity explicitly — the existing OpenRouter fallback in
getApiConfigs handles that case unchanged.
Fixes#3251
- Moved authentication logic to `perplexity-auth.ts` to share logic between search providers and CLI commands.
- Updated authentication priority to prefer browser cookies over OAuth tokens during search operations.
- Modified the `token` CLI command to display active OAuth tokens when both an OAuth token and an API key are configured.
- Added comprehensive unit tests in `perplexity.test.ts` to verify authentication priority and precedence.
- Integrated comprehensive loop guard support for DeepSeek and assistant prose patterns, including configurable stream checks.
- Implemented Moonshot Flavored JSON Schema (MFJS) normalization for improved tool compatibility and enum type inference.
- Added support for Ollama reasoning effort backfilling and Grok-specific service tier cost tracking across providers.
- Expanded model catalog with new entries and unified compatibility logic for improved OpenRouter API integration.
This change introduces a new `openrouter` API type and extensively refactors OpenAI-family streaming providers, centralizing shared logic and improving robustness.
Key changes include:
- **Unified OpenAI-family Logic:** Consolidated core utilities, compat resolution, request shaping, and stream processing into `openai-shared.ts`, reducing duplication across `openai-completions`, `openai-responses`, and `openai-codex-responses`.
- **OpenRouter API Type:** Introduced a dedicated `openrouter` API type with dual-surface compatibility, allowing it to dispatch requests as either OpenAI Chat Completions or Responses.
- **Enhanced Provider Integration:**
- Improved Perplexity search to leverage shared OpenAI streaming transports, including API-key fallback to OpenRouter and support for Perplexity's Responses API.
- Integrated xAI-specific logic directly into the shared `stream.ts` dispatch, removing the dedicated `xai-responses` provider.
- Refined credential parsing for Google Gemini CLI and handling of Azure deployment names.
- **Robustness & Consistency:** Improved error handling for Codex, standardized output token parameter resolution, and ensured consistent application of reasoning suppression across all Chat Completions dialects.
- **New Documentation:** Added `provider-endpoint-constraints.md` to detail endpoint-specific behaviors and quirks for various providers.
- **Telemetry & Debugging:** Extended telemetry propagation to advisor calls and overflow compaction tasks. Improved debugging for Codex WebSocket failures and stream error messages.
- **Tooling & Security:** Updated browser stealth scripts to prevent detection and added a new `ts-no-inline-cast-access` TTSR rule.
- Added optional FetchImpl fields to compaction, proxy, AI, coding-agent, and mnemopi options.
- Threaded injected fetch implementations through OAuth, discovery, and search/LLM request flows.
- Removed exported hookFetch utility and its package entrypoint from utils.
- Replaced global-fetch test monkeypatching with per-test FetchImpl mocks across test suites.
- Forced authenticated ask requests to `experimental`, matching the anonymous fallback since the cookie session ignores pro upgrades.
- Kept TUI collapsed search answers full; capping now only applies in compact mode via `maxAnswerLines`.
- Preserved full multiline task pending preview instead of bounding it.
- Sent the OAuth token as `__Secure-next-auth.session-token` cookie since the ask endpoint ignores bearer headers and silently downgrades to `turbo`.
- Fell back to `result.title` when web results omit `name`.
- Renamed `callPerplexityOAuth` to `callPerplexityAsk` and removed a stray brace.
- Added tests covering OAuth, API-key, and anonymous request shapes.
- Raised default search results to 20 and context size to high.
- Added related questions parsing and return_related_questions request flag.
- Added API-key request-shape tests covering defaults and parsing.
