successfully completed the first two major refactoring steps:\n\n✅ **Rename Function**: `getData` → `fetchUserData` across all files \n✅ **Extract Module**: Created `src/utils/validation.ts` and moved validation functions \n✅ **TypeScript Interfaces**: Added User interface definitions \n\n## What We're Currently Working On\n\nWe are in the middle of **Step 3 & 4** of the comprehensive refactoring:\n\n**Completed:**\n- `src/index.ts` - Updated to use `fetchUserData`\n- `src/api/data.ts` - Function renamed, basic types added\n- `src/utils/helpers.ts` - Validation functions removed\n- `src/utils/validation.ts` - New file created with validation functions\n- `src/services/user.ts` - Import updated to use new validation module\n\n**In Progress:**\n- Adding comprehensive TypeScript types to all functions\n- Implementing proper error handling with try-catch blocks\n- Creating custom error classes for validation errors\n\n## Immediate Next Steps\n\n### 1. Complete TypeScript Type Annotations\n- Add return types to all functions in:\n - `src/api/data.ts` (fetchUserData)\n - `src/services/user.ts` (processUser)\n - `src/utils/validation.ts` (validateEmail, validateAge, validateName)\n - `src/utils/helpers.ts` (any remaining functions)\n- Ensure all function parameters have explicit types\n\n### 2. Implement Error Handling\n- Create custom error classes in a new file `src/utils/errors.ts`:\n - `ValidationError` class\n - `ApiError` class\n- Add try-catch blocks in `src/api/data.ts` for API calls\n- Add try-catch blocks in `src/services/user.ts` for user processing\n- Wrap validation functions with proper error throwing\n\n### 3. Update All Files with Proper Types\nReview each file and ensure:\n- All imports are correctly typed\n- All function signatures have parameters and return types\n- All variables are properly typed\n- All interfaces are exported where needed\n\n### 4. Verification Phase\nAfter completing the above:\n- Run `tsc --noEmit` to check for TypeScript errors\n- Read back all modified files to confirm changes\n- List the project structure to verify file organization\n\n## Files to Focus On Next\n\n**Priority 1 - Error Handling:**\n1. `src/utils/errors.ts` (NEW - create this file)\n2. `src/api/data.ts` (add try-catch)\n3. `src/services/user.ts` (add try-catch)\n\n**Priority 2 - Type Completion:**\n4. `src/utils/validation.ts` (verify all types)\n5. `src/services/user.ts` (verify all types)\n6. `src/index.ts` (verify all types)\n\n**Priority 3 - Verification:**\n7. Run TypeScript compiler\n8. Review all changes\n\nPlease continue with creating the error handling utilities and completing the TypeScript type annotations across all remaining functions." + } + ], + "task_completed": true + }, + "comparison": { + "token_savings_percent": 29.52, + "time_savings_percent": 44.35, + "winner": "hybrid" + } +} \ No newline at end of file diff --git a/packages/opencode/run-benchmark.ts b/packages/opencode/run-benchmark.ts new file mode 100644 index 00000000000..1ba6f5f3da2 --- /dev/null +++ b/packages/opencode/run-benchmark.ts @@ -0,0 +1,264 @@ +#!/usr/bin/env bun +/** + * Standalone benchmark runner for testing compaction methods + * This script tests the benchmark framework without the full TUI dependencies + */ +import { BenchmarkMetrics } from "./src/benchmark/metrics" +import { RefactorTask } from "./src/benchmark/tasks/refactor" +import fs from "fs/promises" +import path from "path" + +const OPENROUTER_API_KEY = "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" +const MODEL = "xiaomi/mimo-v2-flash:free" + +interface ChatMessage { + role: "system" | "user" | "assistant" + content: string +} + +async function callOpenRouter(messages: ChatMessage[], systemPrompt?: string): Promise { + const body: any = { + model: MODEL, + messages: systemPrompt + ?
