doc-summarize
Skill5 starsChanged 6 months agoMITView on GitHub
Summarizes a long document, PDF, transcript, or report into a clear one-page brief with the key takeaways, notable quotes, and any action items. Use when the user asks to summarize, TLDR, give me the short version of, or digest a document. Works on files in the project folder or uploaded directly.
We split this skill into the rules it gives an agent
12 rules. About 0 are common, 11 are distinctive, and 1 is very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈11
Distinctive · estimate
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 12
Ask the user: what's the purpose of the summary?
- Very specific: line 13
Read context/preferences.md — citation style, format preferences
- Distinctive: line 14
If the document is long (>30 pages or >20k words), tell the user roughly how long the summary will take
- Distinctive: line 33
Read or fetch the document.
- Distinctive: line 37
If there are things the document says that contradict other things the user has read (and you have that context), flag it
- Distinctive: line 42
Do not summarize by compression ratio ("reduce to 10%").
- Distinctive: line 43
Do not paraphrase every paragraph.
- Distinctive: line 44
Do not editorialize beyond what the document supports.
- Distinctive: line 45
Do not skip quotes if the document earns them.
- Distinctive: line 79
For research papers / academic: Add a fifth section: "What the authors are wrong or unclear about."
- Distinctive: line 80
For product specs / tech docs: Add a "dependencies and risks" section.
- Distinctive: line 81
If the user asked for a summary to brief someone else: Write the whole thing in a voice-neutral tone, not in the user's voice.
≈ “Common” is an estimate: at least 1 in 5 of the 308,232 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Doc Summarize
Turn a 40-page PDF, a 90-minute meeting transcript, or a dense article into a one-page brief the user can actually use.
Before starting
- Ask the user: what's the purpose of the summary? "For my knowledge," "for a decision I'm making," "for a meeting tomorrow" — the answer changes what you emphasize.
- Read
context/preferences.md— citation style, format preferences - If the document is long (>30 pages or >20k words), tell the user roughly how long the summary will take
What to produce
A markdown file saved to /output/summary-{document-name}-{YYYY-MM-DD}.md with four sections:
- The 30-second version — 3–5 sentences. The core takeaway. If the user only reads this, they got the gist.
- Key points — 5–10 bullets. The things that matter. Each one stands alone.
- Notable quotes or passages — verbatim excerpts if the document is worth quoting (reports, transcripts, academic papers). Include page/timestamp references if available.
- Action items or implications — if the summary has implications for the user (decisions to make, things to follow up on), list them. Skip if not applicable.
Inputs
- The document (required) — PDF, markdown, transcript, text file, article URL
- The purpose (recommended — ask if not given)
- Any prior summaries or notes on related documents in the project folder
How it works
- Read or fetch the document. If it's a URL, pull the content. If it's a PDF, extract the text.
- For long documents: make a pass to identify structure (sections, arguments, conclusions), then a pass to extract the key points
- For transcripts: identify speakers, decisions made, action items explicitly stated
- Draft the four sections. Dense, specific, no padding.
- If there are things the document says that contradict other things the user has read (and you have that context), flag it
- Save the file, tell the user one sentence on what surprised you or what they should look at first
What not to do
- Do not summarize by compression ratio ("reduce to 10%"). Summarize by importance — some documents have three things that matter, others have thirty.
- Do not paraphrase every paragraph. Skip the filler. If 80% of a report is methodology and 20% is findings, give them the findings.
- Do not editorialize beyond what the document supports. If you disagree with the document, that's a separate deliverable.
- Do not skip quotes if the document earns them. Some documents are worth reading for the exact language.
Example output structure
# Summary — Q1 Board Deck (Acme Corp) — 2026-04-18
## The 30-second version
Q1 was a miss on revenue (-8% vs. plan) but a beat on new logo count (+12%). The gap is pricing — new customers came in at lower ACV than plan. CEO is proposing a pricing rework in Q2 and a hiring pause through end of Q2. Board is being asked to approve both.
## Key points
- **Revenue:** $4.2M vs. $4.6M plan. Miss.
- **New logos:** 47 vs. 42 plan. Beat.
- **ACV dropped 14% YoY** — largely due to a new self-serve tier introduced in Q4
- **Net retention:** 108%, flat with Q4, below the 112% target
- **Cash:** 22 months runway, up from 19 in Q4 (thanks to reduced spend)
- **Proposed: pricing rework** — reviewing tier structure and the self-serve plan that's cannibalizing mid-market
- **Proposed: hiring pause** — through end of Q2, open reqs close today, exceptions only for existing backfills
- **Risks called out:** competitor entered the mid-market segment in Feb, churn is ticking up in the self-serve tier
## Notable quotes
> "The self-serve tier has become a revenue problem. It's pulling customers who would otherwise buy the $15K plan into the $3K plan." — CEO letter, p. 3
> "We're not cutting. We're pausing while we figure out why our growth is outpacing our monetization." — CEO letter, p. 5
## Action items / implications
- Board to vote on pricing rework (scope: tier restructure) and hiring pause — both require approval
- Finance to model the revenue impact of three pricing scenarios before next board (dates not specified in deck)
- No action items for you personally unless you're on the pricing committeeCustomization notes
- For transcripts (meetings, interviews). Replace "notable quotes" with "decisions made" and "open questions."
- For research papers / academic. Add a fifth section: "What the authors are wrong or unclear about."
- For product specs / tech docs. Add a "dependencies and risks" section.
- If the user asked for a summary to brief someone else. Write the whole thing in a voice-neutral tone, not in the user's voice. They'll forward it.
- If the document is genuinely low-signal. Tell the user. A short, honest "this document has three things in it, here they are" is better than padding it out to look substantive.
