Lesson 2 of 8
Reliable Summaries
A reliable summary preserves the source’s meaning, uncertainty and important exceptions while reducing length.
Active reading
Source boundary
Use only provided material.
Priority
Keep decisions and caveats.
Verification
Trace claims back to source.
Summarize without inventing certainty
A summary should compress information, not silently resolve ambiguities or add facts that are not in the source.
Ask for unresolved questions, risks or source references when those details matter to the task.
Example
Prompt: “Summarize only from these notes. Separate confirmed decisions from open questions. Do not infer missing owners.”
Quick check
Explain this lesson back in one sentence before continuing. If you cannot, reread the example and key takeaway.
Common mistake
Do not turn tentative wording into a definitive statement.
Key takeaway
A good summary is shorter than the source but faithful to its evidence and uncertainty.
