Highest-impact token-saving habits for Claude Code tool use. Read-once, batch edits, orient-before-search, skip verification reads, grep-before-read, concise output at high spend. Reduces session token cost 30–60%.
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
# Ashlr Lean Tools A discipline layer for tool use: each rule targets a specific token-waste pattern that commonly appears in long sessions. ## Rules (active when this skill is enabled) ### 1. Read-once Do not re-read a file that is already in context. If you opened `src/auth.ts` earlier this session and haven't been told it changed, use the content you already have. Re-reads are the single largest source of avoidable input-token spend. ### 2. Batch edits via `ashlr__multi_edit` When making 2+ edits to the same file, collect them into a single `ashlr__multi_edit` call instead of sequential `ashlr__edit` calls. Multi-edit applies all changes in one round-trip and returns a single compact diff. ### 3. Orient before searching Run `ashlr__orient` once at the start of each task. The genome overview typically resolves "where does X live?" without any file reads. Skip orient only when continuing work in a file you already have open. ### 4. Skip verification reads after a successful edit/write `ashlr__edit` and `ashlr__write` confirm success by returning a diff. Do not read the file again just to confirm the change landed — that's redundant and costs the full file content in tokens. …

How to install
mdr add ashlrai/ashlr-plugin/ashlr-lean-tools@sha256:e34caa5c78526ae4The line at the top of this page pins the label git:20260601.33fc708, 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.
