Slim the instructions Claude Code loads in every session (CLAUDE.md, rules, their imports) without losing a rule - weigh them, sort every block, show the changes, write only on the user's go, prove nothing was lost, weigh again.
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
# Slim
Lighten what every session pays before its first word, and lose no rule.
Resolve `scripts/` from this skill's directory. Run each script with Bash
`run_in_background: true` and read its output when it ends: a foreground
Bash may run in another shell, without the session's `CLAUDE_CONFIG_DIR`
or working directory. `<work>` is a new scratch folder for this run.
Talk in the conversation language.
1. **Weigh.** `node scripts/weigh.cjs --save <work>/before.json`. Show its
table: every file loaded at launch, its size and its share. An argument
narrows the files to slim; the weighing stays whole.
2. **Sort.** Read each file and give every block one destination:
- stays loaded: a rule every session needs, kept short;
- skill: a procedure, or a block for one kind of task. It becomes
`skills/<name>/SKILL.md` in the same scope (`<config>/skills/` or
`<project>/.claude/skills/`), its description saying when it applies;
- `paths:` rule: a block that matters only for matching files. It loads
after a matching Read, Write or Edit, and user-level patterns start
from the session's working directory: a rule needed before any read
stays loaded;
…Read the whole file at its exact version.
How to install
mdr add mirkobozzetto/arsenal/slim@sha256:2281d9e2c4360239The line at the top of this page pins the label git:20261103.e793781, 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.
