📝 Walkthrough

Walkthrough

This PR removes three AI tool implementations (match, read-file, write-file) from the codebase, unregisters them from the tools index, eliminates Gemini-specific reasoning-stripping utilities, refactors chat message handling to use summarizedMessages instead of finalMessages, and updates import paths for better module organization.

Changes

Cohort / File(s)	Summary
Removed tool implementations lib/ai/tools/match.ts, lib/ai/tools/read-file.ts, lib/ai/tools/write-file.ts	Deleted three complete tool definitions including sandbox-based search/file-read/file-write functionality with input validation, execution logic, error handling, and helper utilities.
Tools index update lib/ai/tools/index.ts	Removed imports and tool registrations for read_file, write_file, and match tools from allTools and mode-specific tool subsets.
Perplexity module reorganization lib/ai/tools/web-search.ts	Updated import path from ./perplexity to ./utils/perplexity without changing runtime behavior.
Gemini reasoning logic removal lib/utils/message-processor.ts	Deleted exported functions stripReasoningForGemini, stripReasoningFromMessagesForGemini, and helper isReasoningPart that filtered reasoning parts for Gemini models.
Chat handler refactoring lib/api/chat-handler.ts	Removed Gemini-specific reasoning-stripping invocations, replaced finalMessages with summarizedMessages in message streams, and added generationTimeMs and finishReason metadata to retry and message persistence paths.

Poem

🐰 The tools hop away, reasoning fades from sight,
Gemini's thoughts take a quieter flight.
Files and matches vanish clean,
Leaving streamlined paths between.
A simpler toolbox, fresh and bright! 🌟
