SparseRead cuts agent token use by up to 92.9% by deciding what to read before reading

Open-source SparseRead (GitHub: Liuzedooong/SparseReading, MIT, paper arXiv:2608.22237) targets wasteful agent reading: up to 92.9% token savings and 89% less time while keeping quality.
The pain: ask Claude Code to debug in a repo with hundreds of thousands of lines, and the agent may burn tens of thousands of tokens to find the few lines that matter.
Key idea: decide what enters context before paying for a broad read, not compress afterwards:
- Set reading intent: identify what evidence is needed, what's found, what's missing;
- Locate evidence on demand: targeted search and partial reads per material type (code, docs, tables);
- Budget reads: cap what external content enters context.
It's a training-free reading layer for tool-using agents.
