Claude Code sees all sections in your Markdown file with their IDs, titles, and line ranges.
Read only the section you need — ~300 tokens instead of ~3,000 for a full file.
Modify only that section — ~200 output tokens instead of rewriting the entire file.
Everything you need to edit files efficiently in Claude Code.
9 automated scenarios, 3 user types, fully reproducible. No manual scoring.

Instead of reading entire files, TokSlash lets Claude Code read and modify only specific blocks (sections) of a Markdown file. A 1,000-line README might have a 60-line "Installation" section — reading just that block saves ~94% of input tokens. Block-level writes save output tokens too.
Block-level editing currently supports Markdown (.md) files only. Other text files (.py, .js, .json, .yaml, etc.) work with full-file read/write and benefit from the persistent cache. Binary files and files over 5MB are excluded from caching.
TokSlash automatically falls back to full-file reads and writes. Nothing breaks. Your files are still editable — you just won't get the token savings until the next day (quota resets at midnight UTC).
No. TokSlash runs entirely locally as an MCP server. Your files, cache, and index never leave your machine. The only network call is a one-time license activation check (optional — works offline too).
TokSlash automatically creates a backup in .tokslash/backups/ before every modification. You can restore any version at any time. The safety engine also verifies file integrity before and after each change.
Yes. Block editing is based on the CommonMark + GFM standard and works with Chinese content, CJK characters, and mixed-language documents.
