Text Editor

Provide an LLM-friendly file editing tool for reading, writing, and patching text files.

What It Does

This plugin exposes a native text editing tool that agents can use to inspect files, write complete contents, and apply validated patch operations while tracking file freshness between reads and edits.

Main Behavior

• Read
  • Reads whole files or line ranges with token-aware limits.
  • Records file metadata so later patch operations can detect stale edits.
• Write
  • Writes full file contents and then re-reads the resulting file for confirmation.
• Patch
  • Validates edit structures before applying them.
  • Rejects edits if the file changed since it was last observed.
  • Reads back the affected patch region after applying changes.
• Extension hooks
  • Exposes before and after extension points for read, write, and patch operations.
