claude-sdk-tools@1.0.0-beta.5

Added

• File read tools: Find, ReadFile, Grep, Head, Tail, Range, SearchFiles
• File write tools: CreateFile, DeleteFile, DeleteDirectory
• PreviewEdit and EditFile tools for staged edits with diff preview
• Exec tool with structured args, multi-step pipelines, and permission model
• Pipe tool for chaining tool outputs
• IFileSystem abstraction with NodeFileSystem and MemoryFileSystem for testing
• Ref system for paginating large tool results that exceed context threshold
• Path expansion supporting ~, $HOME, and relative paths in all tools
• Split PreviewEdit edits into lineEdits (structural, bottom-to-top) and textEdits (text-search, applied after lineEdits)
• Export IFileSystem, NodeFileSystem, MemoryFileSystem, nodeFs singleton via ./fs entry
• Add appendFile to IFileSystem, NodeFileSystem, and MemoryFileSystem
• Add TypeScript language tools: ts_diagnostics, ts_hover, ts_references, ts_definition
• Add append operation to EditFile
• ReadFile supports PDF and image files with MIME type detection and magic bytes validation

Changed

• ReadFile accepts image/* to read any supported image format; the format is detected from file content rather than the declared type
• Removed the 500KB limit on text file reads
• Tool handlers return structured output with textContent and optional attachments

Fixed

• Package now publishes CJS alongside ESM with working sourcemaps
• Normalise tilde and environment variable paths in EditFile
• Find tool follows symlinks with cycle detection
• Binary files are blocked from text reads when the format is recognised; unrecognised formats are still treated as text
