AI coding assistants consume tokens for every line of context they process. Reading a 500-line file to understand a single function wastes context window capacity, increases costs, and slows responses. TokenLean solves this with 32 specialized CLI tools that extract exactly the information needed – nothing more.
Instead of reading entire files, run targeted commands like tl-exports to get module signatures in roughly 50 tokens instead of thousands.
