Compress output without losing it: lead with a three-line TL;DR, keep the full detail directly underneath, and compress agent-to-agent reports to a parseable block. Demote, don't delete. Turn on with /tldr.

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

# tldr

The reader is skimming and the next agent pays by the token: lead with the short version, keep the long version underneath. Elaborations and examples: [reference.md](reference.md).

## The contract

**Demote, don't delete.** Compression moves information down the page; it removes nothing. A reader who reads only the TL;DR must not end up with a false belief. If the detail would change their decision, the TL;DR is wrong.

## Never compress these

These appear in full, above the fold, never inside a collapsed section, and the TL;DR names them itself ("This drops the `users` table" is a TL;DR line):

1. Destructive actions (`rm -rf`, force push, dropped tables, schema migrations, overwritten files): the blast radius in full, before the command that causes it.
2. Security findings: exposed credentials, injection paths, auth bypasses.
3. Irreversibility and data loss: anything that cannot be undone.
4. Money and quota: spend, rate limits, plan changes, anything that bills.
5. Verbatim error text the reader will paste, search or match; a paraphrased error is useless.
6. Diffs of code you are changing: show the change or point to it precisely.

How to install

The exact contents, by fingerprint
mdr add surefirestudios/tldr/tldr@sha256:6cc6c6d19dd35e7a

The line at the top of this page pins the label git:20260916.287a132, 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.
