Turn a long document, PDF, transcript, spreadsheet or log into a compact working digest the conversation can continue from. Use when the user shares or pastes something long (several pages or more) and wants to discuss, analyze, compare or use it over more than one message, or asks to summarize a document so they can keep working with it.
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
# Document digest A long attachment is re-sent with every later message of the conversation. A digest that keeps what the work needs lets the rest of the work run on a fraction of it, most of all in a fresh conversation that starts from the digest instead of the file. ## Write the digest In the user's language, inside one code block so it copies cleanly, at most about a tenth of the source and never more than 800 words: 1. **What it is**: title, author or source, date, length, purpose, in one or two lines. 2. **Map**: the sections or parts in order, one line each, with page, slide, sheet or timestamp references, so a later question can go straight to the right place. 3. **Key content**: the claims, decisions, requirements, figures and definitions the user is likely to need, each with its reference. Quote exact wording only where it matters: legal terms, numbers, names, error messages. 4. **Gaps and doubts**: what the document leaves open, contradicts or gets wrong, in a line each. Fit the digest to what the user said they want to do with the document: a contract review keeps obligations, dates and penalties; a dataset keeps the …

How to install
mdr add egorfedorov/claude-context-optimizer/doc-digest@sha256:840d78123993af4aThe line at the top of this page pins the label git:20261017.dfb62c2, 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.
