How to read winnow stubs in tool results. A block marked "[winnow] ... hidden" was judged unlikely to matter for the current task and replaced with a short summary plus a recall key; call winnow_recall to restore it. Use when a tool result contains "[winnow]" lines or when winnow_recall / winnow_stats tools are available.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# winnow
winnow sits between Claude Code's tools and your context. After `Read`, `Bash`, or `Grep` returns a large result, winnow splits it into blocks, asks a System One model (TypeSafe's Jev, or an LLM-backed adapter) one yes/no question per block ("is this block needed for the current task?"), and replaces the low-probability blocks with a stub.
## What a stub looks like
```
[winnow] Lines 41-188 (148 lines) hidden: judged unlikely to matter for the current task (relevance <= 0.22).
[winnow] Summary: Boilerplate license header and the argparse setup for flags that are not part of this task.
[winnow] Full text cached as key a1b2c3d4e5f6. Call winnow_recall(key="a1b2c3d4e5f6", start=41, end=188) if you need it.
```
## How to treat it
- The summary is written by a cheap model and preserves identifiers, paths, numbers and error text. Trust it for orientation, not for exact values.
- If the hidden lines might matter after all, call the `winnow_recall` tool with the key. Add `start` and `end` to fetch only part of the cached text. Do not re-run the original command just to see the hidden part; recall is cheaper and does not re-trigger side effects.

How to install
mdr add ghalebdweikat/winnow/winnow@sha256:76a48abb7fb53b45The line at the top of this page pins the label git:20260917.9f37132, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
