From a4ba55db236a40f195058fd087e208e98f15be33 Mon Sep 17 00:00:00 2001 From: Roo Code Date: Fri, 18 Jul 2025 13:21:35 +0000 Subject: [PATCH] feat: add support for separate apply models for diff operations - Add apply model configuration to provider settings schema - Create ApplyModelDiffStrategy for using dedicated apply models - Update Task class to support apply model configuration - Add comprehensive tests for the new functionality This addresses issue #5880 by allowing users to configure separate models like Morph Fast Apply or Relace Instant Apply for applying changes instead of having the main chat model generate diffs. Benefits: - Reduced token consumption for file edits - Improved reliability for complex changes - Better performance for continuous edits - Support for specialized apply models --- packages/types/src/provider-settings.ts | 8 + .../apply-model-diff-strategy.test.ts | 116 ++++++++++++ .../strategies/apply-model-diff-strategy.ts | 173 ++++++++++++++++++ src/core/task/Task.ts | 18 +- 4 files changed, 309 insertions(+), 6 deletions(-) create mode 100644 src/core/diff/strategies/__tests__/apply-model-diff-strategy.test.ts create mode 100644 src/core/diff/strategies/apply-model-diff-strategy.ts diff --git a/packages/types/src/provider-settings.ts b/packages/types/src/provider-settings.ts index be74ae6bb4..f4c0fcb9b2 100644 --- a/packages/types/src/provider-settings.ts +++ b/packages/types/src/provider-settings.ts @@ -71,6 +71,14 @@ const baseProviderSettingsSchema = z.object({ reasoningEffort: reasoningEffortsSchema.optional(), modelMaxTokens: z.number().optional(), modelMaxThinkingTokens: z.number().optional(), + + // Apply model configuration for separate diff application + applyModelEnabled: z.boolean().optional(), + applyModelProvider: providerNamesSchema.optional(), + applyModelId: z.string().optional(), + applyModelApiKey: z.string().optional(), + applyModelBaseUrl: z.string().optional(), + applyModelTemperature: z.number().nullish(), }) // Several of the providers share common model config properties. diff --git a/src/core/diff/strategies/__tests__/apply-model-diff-strategy.test.ts b/src/core/diff/strategies/__tests__/apply-model-diff-strategy.test.ts new file mode 100644 index 0000000000..b38a5efc8d --- /dev/null +++ b/src/core/diff/strategies/__tests__/apply-model-diff-strategy.test.ts @@ -0,0 +1,116 @@ +import { describe, it, expect, vi, beforeEach } from "vitest" +import { ApplyModelDiffStrategy } from "../apply-model-diff-strategy" +import { Task } from "../../../task/Task" + +// Mock the Task class +const mockTask = { + providerRef: { + deref: () => ({ + getSettings: () => ({ + applyModelEnabled: false, + applyModelProvider: "openai", + applyModelId: "gpt-4", + applyModelApiKey: "test-key", + applyModelBaseUrl: "https://api.openai.com/v1", + applyModelTemperature: 0.1, + }), + }), + }, +} as unknown as Task + +describe("ApplyModelDiffStrategy", () => { + let strategy: ApplyModelDiffStrategy + + beforeEach(() => { + strategy = new ApplyModelDiffStrategy(mockTask, 1.0) + }) + + it("should have correct name", () => { + expect(strategy.getName()).toBe("ApplyModel") + }) + + it("should return tool description", () => { + const description = strategy.getToolDescription({ cwd: "/test" }) + expect(description).toContain("apply_diff") + expect(description).toContain("AI-powered apply model") + expect(description).toContain("/test") + }) + + it("should handle disabled apply model", async () => { + const originalContent = "function test() { return 1;
