Token-saving Java file reader. Use when working with Java files (.java) to reduce token usage. Auto-triggers when exploring, reading, or understanding Java classes, services, controllers, entities, or any .java files. Run jskim before reading raw Java source when you need structural context first, then inspect only the lines you need.

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

# jskim — Java Token Saver for Spring Boot

A CLI tool that summarizes Java files compactly, saving 70-80% of input tokens. Optimized for Spring Boot projects: REST controllers, DI wiring, configuration properties, Lombok, records, Spring Modulith packages.

## Requirements

Python 3.10+ — install via pip:
```bash
pip install jskim
```

**Before first use**, verify jskim is installed by running `jskim --version`. If you get "command not found", tell the user:
> jskim is not installed. Install it with: `pip install jskim`

Do not attempt to run jskim commands until it is confirmed installed. Fall back to your normal file-reading tools if the user declines to install it.

## Usage

`jskim` auto-detects whether you're pointing at a file or directory, and whether you're asking for a summary or method extraction. A flag that does not apply to the detected mode is reported on stderr (`Warning: --grep not used in project mode, ignored`), never silently dropped.

How to install

The exact contents, by fingerprint
mdr add garvit-joshi/jskim/jskim@sha256:b050c93df65a6ece

The line at the top of this page pins the label git:20260912.1aa4ac6, 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.
