The tour
What it does
01
Token count per file
Every file shows its size in tokens, so you see at once what eats the context window.
02
Budget bar
Set a budget for the model you use; the bar fills as you add files and warns before you go over.
03
Smart ignores
Build output, lock files and vendored code are skipped by default, following your .gitignore.
04
One bundle, one manifest
Export a single Markdown file with a table of contents, or a folder with a manifest an agent can read.
How it works
Who does what
- 01 You Drop the repository or the files you want to hand over.
- 02 Contextpack Contextpack counts tokens, applies ignores and orders files with your notes first.
- 03 You Trim until it fits the budget, then export.
- 04 Agent The next session starts from one well-organised file instead of guessing.
