Pi Skimmer
jon-devlapaz's MIT-licensed Pi coding-agent extension that filters text and JSON through Jev with explicit per-session consent, bounded requests, owner-only recovery files, and unjudged material preserved.

Highlights
- Two Jev-backed tools for the Pi coding agent: skim_text keeps relevant chunks with line ranges, filter_items keeps relevant JSON records.
- Consent is separate from /typesafe enable, scoped to the session and working directory, and revoked on reload; headless use needs PI_SKIMMER_ENABLED=1.
- Budget guards: 100 attempted requests per extension session, a shared estimated $1 daily spending cap, a 10 s request timeout and a 30 s tool timeout.
- skim_text defaults to 2,000-character chunks at 10% overlap and a 0.5 relevance threshold; filter_items takes 1-256 items on literal top-level fields.
- Input over 256,000 UTF-8 JSON bytes fails rather than truncating, and unjudged items are retained with warnings instead of being dropped.
Watch out
MIT-licensed. Needs Pi 1.2.0+ and Node 22.19+; the npm package is promised after release, with git install available now. Field selection is not output redaction, spending estimates are not billing guarantees, and relevance scores are probabilistic, so the README says to read originals before critical decisions. It is a native Pi extension, not a wrapper around the Skimmer CLI.
Questions about this entry
Short answers drawn from the linked project or page.
A Pi coding-agent extension from jon-devlapaz that filters text and JSON records toward a stated goal using Jev, through the pi-typesafe bridge. It is a native extension rather than a wrapper around the Skimmer CLI.
Two: skim_text retains relevant chunks of supplied text with line ranges, and filter_items retains relevant JSON records, optionally showing Jev only selected fields. Both take a focused goal and an optional source label.
pi install git:github.com/jon-devlapaz/pi-skimmer, or pi install npm:pi-skimmer after the npm release; also install [email protected] for the /typesafe login and status commands. Restart Pi or run /reload, then /typesafe login and /skim enable. Pi 1.2.0+ and Node 22.19+ are required.
Consent is explicit and separate from /typesafe enable: /skim enable is scoped to the current Pi session and working directory and is revoked on reload, and the confirmation names the destination host. Headless runs need the operator to set PI_SKIMMER_ENABLED=1 first.
The SDK client allows 100 attempted requests per extension session and sets a shared estimated daily spending cap of $1, with PI_TYPESAFE_MAX_* caps still applying; the default request timeout is 10 seconds and the overall tool timeout is 30 seconds. Estimates are not billing guarantees.
No. Jev receives only the selected fields, but retained records and local originals keep every field, and returned records can be visible to your coding model; the README warns against including credentials or unapproved data even in unselected fields.
Unjudged items are retained with warnings and degraded API outcomes are marked as errors rather than successful judgments. Full input and results are saved in temporary owner-only directories (0700, files 0600) that persist until cleaned up, and displayed output is capped with truncation metadata and paths to the recovery files.

Decision-driven, extractive context compaction for the Pi coding agent: Jev judges complete read-only tool pairs and ordinary code removes the ones it rates unnecessary, keeping retained records in a JSON-lines transcript packet instead of a generated summary.
