Tablestakes

If you're wrangling GitBook or Notion exports where tables get collapsed into single-line HTML blobs, this converts them to clean pipe format for LLM reading and writes changes back without corrupting the markup. Exposes list_tables for discovery, read_table for extraction, and surgical operations like update_cells, insert_row, delete_column. All writes require a version hash to prevent stale overwrites. The token savings are real: 91% on table discovery, 39% on HTML reads, 73% on GFM edits compared to using generic file read/write tools. Handles both GitHub Flavored Markdown and GitBook's collapsed HTML with width attributes intact.
