Claude Code v0.2.55

# Claude Code v0.2.55 Changelog

• New permission checking functions for file operations:
• d_() - Validates read permissions before file access, providing clear error messages when permissions haven't been granted
• Vg() - Validates write permissions before file modifications, ensuring proper access control

These functions improve security by checking if Claude has been granted the necessary permissions before attempting file operations. Users will see messages like:

• "Claude requested permissions to read from [path], but you haven't granted it yet."
• "Claude requested permissions to write to [path], but you haven't granted it yet."

• Simplified memory update display with the new Xk2() component
• Shows concise memory update notifications without diff details
• Displays: "[MemoryType] updated in [path] · /memory to edit"
• Cleaner UI that reduces visual clutter while maintaining essential information

• New Tl2() function parses context limit errors to extract token information
• Automatically detects when input length + max_tokens exceed the context limit
• Extracts and returns structured data: { inputTokens, maxTokens, contextLimit }
• Helps users understand token usage and adjust their requests accordingly

• New environment variable: MCP_TOOL_TIMEOUT
• Default: 100,000,000ms (increased from standard timeout)
• Allows longer-running MCP tool operations
• Set via: export MCP_TOOL_TIMEOUT=100000000

• Modified environment variable handling: MCP_TIMEOUT
• Default: 30,000ms (30 seconds)
• Now properly handles empty string values with fallback

• Centralized status theme logic with EL1() function
• Cleaner code for determining UI themes based on operation status
• Supports states: "tool-use", "responding", "thinking", and "normal"

• New helper functions for consistent UI rendering:
• im5() - Returns appropriate spinner style for current status
• nm5() - Returns color theme for current status
• am5() - Returns message style for current status

• Changed from default import to named import for Node.js streams
• Before: import pg4 from "stream"
• After: import { Readable as ug4 } from "stream"

• Relocated process.cwd import for better module organization
• Now imported as: import { cwd as NX0 } from "node:process"

• Enhanced Ak5() function (formerly Bb5()) now checks for context limit errors
• Automatically retries requests that fail due to context limits
• Provides better handling of token-related errors

• Fixed memory update notification display to be more concise and user-friendly
• Improved error message clarity for permission-related failures
• Better handling of empty MCP timeout environment variables

• Removed unused variables: RG9, zi2, xZ
• Removed redundant import: Rn2 from "node:process"
• Added new utility function Yf() for internal operations
• Significant code refactoring with ~4254 function renames for better code organization
