Skimmer
A Go CLI by dorkitude that skims pages, files, and lists with Jev, keeping only the chunks that help with your stated goal. The README's example kept 4 of 40 chunks and cut 71k characters to 7.6k, an 89% saving, for whatever agent reads next.

Highlights
- One command skims a URL toward a goal; the README example kept 4 of 40 chunks and reported 71k to 7.6k characters, an 89% saving.
- Material is split into roughly 2,000-character chunks with 10% overlap, and kept chunks are cited by line range, as in path:40-58.
- Jev gets one yes/no question per chunk, does this help with the goal, batched to fit context and run in parallel.
- If Jev cannot judge a chunk, because of a failed batch for example, skimmer keeps it rather than silently dropping it.
- It is the chunk filter from dorkitude's webctl, pulled out so it works on any page, file, or list rather than only search results.
Quickstart
bash
brew install dorkitude/tap/skimmer
skimmer skim https://en.wikipedia.org/wiki/Bloom_filter \
-g "What is the false positive rate formula, and how do I pick the number of hash functions?"Watch out
README and GitHub metadata reviewed 2026-10-17; the digest truncates the apt install command and stops before any Jev API-key or configuration section, so those steps were not available. The 89% saving and the kept-4-of-40 figure come from a single README example, not a benchmark, and pre-0.1.104 source installs are told to switch to the tap.
Questions about this entry

A Go CLI from dorkitude that skims web pages, files, and lists toward a stated goal, keeping only the parts that help and citing kept chunks by line range.
It asks Jev one yes/no question per chunk or list item, whether that chunk helps with your goal, and keeps the chunks whose probability says yes, batching calls to fit context and running them in parallel.
On macOS and Linux use brew install dorkitude/tap/skimmer, a signed and notarized prebuilt binary that needs neither Go nor the Xcode Command Line Tools; Debian and Ubuntu have an apt repository, though the digest truncates its command.
The README's Wikipedia example reported 1 source, kept 4 of 40 chunks, and a drop from 71k to 7.6k characters, an 89% saving. That is one recorded run, not a general benchmark.
When Jev cannot judge a chunk, for example after a failed batch, skimmer keeps that chunk instead of silently dropping it, so an outage degrades to reading more rather than losing content.
Web pages, files, and stdin, plus lists in JSON, JSONL, or plain lines. For lists it returns kept items in the same format as the input.
It is the chunk filter from dorkitude's webctl, extracted into a standalone tool so it works on any material rather than only search results; webctl itself remains a separate project.
