shevanio 76ad6667f1 feat: improve rate limit error handling with user-friendly messages
- Add rate_limit error type to ErrorInfo classification
- Implement isRateLimitError() and extractRetryAfter() utilities
- Enhance ClaudeProvider error handling with actionable messages
- Add comprehensive test coverage (8 new tests, 162 total passing)

**Problem:**
When hitting API rate limits, users saw cryptic 'exit code 1' errors
with no explanation or guidance on how to resolve the issue.

**Solution:**
- Detect rate limit errors (429) and extract retry-after duration
- Provide clear, user-friendly error messages with:
  * Explanation of what went wrong
  * How long to wait before retrying
  * Actionable tip to reduce concurrency in auto-mode
- Preserve original error details for debugging

**Changes:**
- libs/types: Add 'rate_limit' type and retryAfter field to ErrorInfo
- libs/utils: Add rate limit detection and extraction logic
- apps/server: Enhance ClaudeProvider with better error messages
- tests: Add 8 new test cases covering rate limit scenarios

**Benefits:**
 Clear communication - users understand the problem
 Actionable guidance - users know how to fix it
 Better debugging - original errors preserved
 Type safety - proper TypeScript typing
 Comprehensive testing - all edge cases covered

See CHANGELOG_RATE_LIMIT_HANDLING.md for detailed documentation.

@automaker/utils

Shared utility functions for AutoMaker.

Overview

This package provides common utility functions used across AutoMaker's server and UI. It includes error handling, logging, conversation utilities, image handling, and prompt building.

Installation

npm install @automaker/utils

Exports

Logger

Structured logging with context.

import { createLogger, LogLevel } from '@automaker/utils';

const logger = createLogger('MyComponent');
logger.info('Processing request');
logger.error('Failed to process:', error);
logger.debug('Debug information', { data });

Error Handler

Error classification and user-friendly messages.

import {
  isAbortError,
  isCancellationError,
  isAuthenticationError,
  classifyError,
  getUserFriendlyErrorMessage,
} from '@automaker/utils';

try {
  await operation();
} catch (error) {
  if (isAbortError(error)) {
    console.log('Operation was aborted');
  }

  const errorInfo = classifyError(error);
  const message = getUserFriendlyErrorMessage(error);
}

Conversation Utils

Message formatting and conversion.

import {
  extractTextFromContent,
  normalizeContentBlocks,
  formatHistoryAsText,
  convertHistoryToMessages,
} from '@automaker/utils';

const text = extractTextFromContent(contentBlocks);
const normalized = normalizeContentBlocks(content);
const formatted = formatHistoryAsText(messages);
const converted = convertHistoryToMessages(history);

Image Handler

Image processing for Claude prompts.

import {
  getMimeTypeForImage,
  readImageAsBase64,
  convertImagesToContentBlocks,
  formatImagePathsForPrompt,
} from '@automaker/utils';

const mimeType = getMimeTypeForImage('screenshot.png');
const base64 = await readImageAsBase64('/path/to/image.jpg');
const blocks = await convertImagesToContentBlocks(imagePaths, basePath);
const formatted = formatImagePathsForPrompt(imagePaths);

Prompt Builder

Build prompts with images for Claude.

import { buildPromptWithImages } from '@automaker/utils';

const result = await buildPromptWithImages({
  basePrompt: 'Analyze this screenshot',
  imagePaths: ['/path/to/screenshot.png'],
  basePath: '/project/path',
});

console.log(result.prompt); // Prompt with image references
console.log(result.images); // Image data for Claude

File System Utils

Common file system operations.

import { ensureDir, fileExists, readJsonFile, writeJsonFile } from '@automaker/utils';

await ensureDir('/path/to/dir');
const exists = await fileExists('/path/to/file');
const data = await readJsonFile('/config.json');
await writeJsonFile('/config.json', data);

Usage Example

import { createLogger, classifyError, buildPromptWithImages } from '@automaker/utils';

const logger = createLogger('FeatureExecutor');

async function executeWithImages(prompt: string, images: string[]) {
  try {
    logger.info('Building prompt with images');

    const result = await buildPromptWithImages({
      basePrompt: prompt,
      imagePaths: images,
      basePath: process.cwd(),
    });

    logger.debug('Prompt built successfully', { imageCount: result.images.length });
    return result;
  } catch (error) {
    const errorInfo = classifyError(error);
    logger.error('Failed to build prompt:', errorInfo.message);
    throw error;
  }
}
