The skill

The genshijin compress skill shrinks natural-language memory files such as CLAUDE.md and todo lists into a terse caveman style to save input tokens, while it keeps code, URLs, paths and structure.

Only when you ask.

The habit

Smaller memory files, same facts.

↻ Runs by itselfyou name a file

How the habit works.
You don't have to.

Three questionsWhen does it start? How does it check its work? What does it remember?

01

It starts by itself

you name a file. Runs in Claude Code routine.

  • ↻ you name a file
  • /genshijin-compress <filepath>

02

It checks its work

output validation passes. If a check fails, it tries again.

  • ✓the skill's output validation passes
  • ✓FILE.original.md backup exists before overwrite
  • ✓every fenced code block matches the original exactly
  • ✓heading count is the same as in the original

03

It remembers

compressed files log. The next run reads it first: files already compressed, so .original.md copies are skipped.

loops/genshijin-compress-loop/log.md

One run, step by step.
Then it stops.

Stop ruleStops after one file per run, with at most 2 fix retries.

  1. 01

    Check the file

    The agent refuses code files and secret files like .env, keys or anything under .ssh.

  2. 02

    Back it up

    The readable version is saved as FILE.original.md before anything changes.

  3. 03

    Compress the prose

    The CLI from the scripts folder drops polite filler and hedges, but leaves code, URLs, paths and numbers alone.

  4. 04

    Validate

    The output check runs; on errors only the broken parts are fixed, up to 2 times.

  5. 05

    Report

    You get the result, or an error report with the original file left unchanged.

  6. 06

    Log the run

    The file name and outcome go into the run log.

What it may do.
Nothing more.

Safe by defaultIt writes only in its own folder and asks you before anything goes out.

Is it for you?
Use it when it fits.

Quick checkRead both lists. If the left one sounds like you, the Genshijin Compress skill helps.

Use it when

  • ✓ your CLAUDE.md has grown long
  • ✓ you want fewer input tokens per run
  • ✓ your notes are full of polite filler

Skip it when

  • – the file is code or config
  • – the file holds secrets or keys
