Summarize a document, meeting transcript, or email — pick a style that matches what the content actually is, and fold long input forward in sections instead of losing the back half. Use when the user pastes or points at a transcript, email, PDF, or long document and asks for a summary, action items, or key decisions.
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
# Summarize
A summary that drops the back half of a long document is worse than no
summary — it looks complete and isn't. Everything here exists to stop that:
pick the right style for what the content *is*, and never lose earlier
material when the input is too long to read in one pass.
## Procedure
1. **Identify what you're summarizing before you pick a style.** Read the
first portion and classify it:
- **Transcript** — speaker labels, timestamps, back-and-forth dialogue.
- **Email** — `From:`/`To:`/`Subject:` headers, a greeting/sign-off, one
author's voice.
- **Document / PDF / business content** — reports, decks, specs; prose
without dialogue structure.
When it's genuinely ambiguous, say which you picked and why in one clause
rather than silently guessing — the style below changes with it.
2. **Get the full text.** For an indexed document, `index_document` it first
if it isn't already (`list_indexed_documents` to check), then either call
`summarize_document(file_path, summary_type)` or `dump_document` first if
you need the raw extracted text. For pasted text, a plain text file, or a
…
The line at the top of this page pins the label v1.0.2, 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.
