From 936d65ae1c4d0b713fa466669a2a6c605f1ea0b2 Mon Sep 17 00:00:00 2001 From: decolua Date: Thu, 30 Apr 2026 18:00:38 +0700 Subject: [PATCH] Enhance chat handling and introduce Caveman feature - Refactored handleChatCore to include Caveman functionality, allowing for terse-style system prompts to reduce output token usage. - Updated APIPageClient to manage Caveman settings, including enabling/disabling and selecting compression levels. - Adjusted AntigravityExecutor to consolidate function declarations for compatibility with Gemini. - Removed unnecessary console logs during translator initialization across multiple routes. --- open-sse/executors/antigravity.js | 29 ++--- open-sse/handlers/chatCore.js | 21 +++- open-sse/rtk/caveman.js | 100 ++++++++++++++++++ open-sse/rtk/cavemanPrompts.js | 35 ++++++ open-sse/translator/index.js | 10 +- .../dashboard/endpoint/EndpointPageClient.js | 90 +++++++++++++++- src/app/api/v1/api/chat/route.js | 1 - src/app/api/v1/chat/completions/route.js | 1 - src/app/api/v1/messages/route.js | 1 - src/app/api/v1/responses/route.js | 1 - src/app/api/v1beta/models/[...path]/route.js | 1 - src/lib/localDb.js | 2 + src/mitm/server.js | 19 ++-- src/sse/handlers/chat.js | 2 + 14 files changed, 265 insertions(+), 48 deletions(-) create mode 100644 open-sse/rtk/caveman.js create mode 100644 open-sse/rtk/cavemanPrompts.js diff --git a/open-sse/executors/antigravity.js b/open-sse/executors/antigravity.js index 36c38f1..ce27a30 100644 --- a/open-sse/executors/antigravity.js +++ b/open-sse/executors/antigravity.js @@ -67,24 +67,17 @@ export class AntigravityExecutor extends BaseExecutor { let tools = body.request?.tools; if (tools && tools.length > 0) { - tools = tools - .map(group => { - if (!group.functionDeclarations) return group; - const cleanedDeclarations = group.functionDeclarations.map(fn => ({ - ...fn, - name: sanitizeFunctionName(fn.name), - parameters: fn.parameters - ? cleanJSONSchemaForAntigravity(structuredClone(fn.parameters)) - : { type: "object", properties: { reason: { type: "string", description: "Brief explanation" } }, required: ["reason"] } - })); - - return { - ...group, - functionDeclarations: cleanedDeclarations - }; - }) - .filter(group => group.functionDeclarations?.length > 0) - .slice(0, 1); + // Merge all groups into a single functionDeclarations group (Gemini expects 1 group) + const allDeclarations = tools.flatMap(group => + (group.functionDeclarations || []).map(fn => ({ + ...fn, + name: sanitizeFunctionName(fn.name), + parameters: fn.parameters + ? cleanJSONSchemaForAntigravity(structuredClone(fn.parameters)) + : { type: "object", properties: { reason: { type: "string", description: "Brief explanation" } }, required: ["reason"] } + })) + ); + tools = allDeclarations.length > 0 ?
