Jint
A semantic linter that builds state from Tree-sitter and classifies it against user-defined TypeScript rules using Typesafe's Jev, then turns the classification values into actionable output through per-rule callbacks. The binary bundles its own runtime.

Highlights
- Constructs state with Tree-sitter, classifies it against user-defined rules via Typesafe's Jev.
- Per-rule callbacks turn classification values into actionable linter output.
- Rules are written in TypeScript; the shipped binary bundles virtual modules and the Bun runtime.
- README links a blog post and two commits where jint refactored its own UI and input walker.
- GitHub metadata: MIT license, TypeScript repo, created 2026-10-05, last pushed 2026-10-14.
Quickstart

README and GitHub metadata reviewed 2026-10-17. The digest excerpt cuts off mid-sentence in the Linux requirements section, so platform support beyond that snippet, performance numbers and pricing are not evidenced.
Questions about this entry
Short answers drawn from the linked project or page.
jint is an extensible semantic linter: it constructs state with Treesitter, classifies that state against a set of user-defined rules using Typesafe's Jev, and turns the classification values into actionable output via per-rule callbacks.
Jev performs the classification step: jint builds state from source with Tree-sitter, asks Jev to classify it against user-defined rules, and per-rule callbacks convert the returned classification values into linter output. The digest does not show the underlying Jev calls.
The README shows npm install -g @sedulus/jint@rc (or add it as a devDependency) and npx @sedulus/jint@rc --version. An install script is also offered via curl from the repo's main branch, with a VERSION variable to pin releases.
No. The README's "No runtime needed" section says the binary ships with virtual modules and the Bun runtime, so you do not need a JS runtime locally to write your own .ts rules.
User-defined rules are TypeScript (.ts) files, per the README's runtime note. The digest does not include a full example rule or the callback API.
The README lists two commits as results: jint being used to refactor a component of jint's own UI, and to refactor its input walker. These are the only usage reports in the digest.
The sedulustech organisation publishes it under MIT; GitHub metadata in the digest shows 14 stars, creation 2026-10-05 and a push on 2026-10-14. The install instructions point at a release candidate (@rc), so treat it as early.

A Claude Code plugin whose /fc command shrinks old tool output in about a second: it keeps the start and end, saves every cut to a file Claude can read back, and an optional Jev pass picks which outputs to keep whole. No API key needed; /compact stays untouched.
