Summarization

Reduce reading time while preserving the source's meaning, evidence, decisions, uncertainty, and useful detail.

Runtime Compatibility

• Resolve bundled files relative to this skill directory.
• Use tools available in the active runtime to read the actual source material.
• Do not claim full coverage of inaccessible, truncated, or unsupported input.
• Verify extraction quality when the source is a scan, recording, or complex file.

Intake

Infer these settings from the request and source:

• audience;
• purpose;
• output length;
• required format;
• facts that must survive compression;
• whether attribution to speakers or documents matters.

When the request is underspecified, choose a practical format and state the compression level in one short line.

Workflow

1. Establish source boundaries

   • Identify every file, message range, URL, transcript, or diff included.
   • Note missing pages, failed extraction, inaudible segments, or truncation.

2. Build a source map

   • Record the central claim or purpose.
   • Capture decisions, evidence, dates, quantities, people, risks, and open items.
   • Separate facts, opinions, proposals, and unresolved statements.

3. Rank information

   • Keep what the target reader needs to decide, act, understand, or verify.
   • Remove repetition, scene-setting, and low-impact detail unless requested.

4. Write the summary

   • Put the bottom line first.
   • Group related points rather than following source order mechanically.
   • Preserve qualifications that change the meaning of a claim.

5. Audit against the source

   • Check names, figures, dates, units, ownership, and negation.
   • Confirm that no new conclusion was introduced.
   • Flag contradictions instead of silently resolving them.

Format Selection

Executive Brief

Use for reports, proposals, and decision material:

• bottom line;
• strongest evidence;
• risks or uncertainty;
• required decision;
• next actions.

Technical Summary

Use for specifications, architecture, incidents, and code:

• purpose and scope;
• behavior or design;
• interfaces and dependencies;
• important decisions;
• trade-offs and limitations;
• breaking changes or follow-up work.

Meeting Or Conversation

Use for notes, chats, and email threads:

• decisions;
• action items with owner and due date when stated;
• key reasoning;
• disagreements;
• unresolved questions.

Do not assign an owner or deadline that was not explicitly agreed.

Research Digest

Use for papers and analytical material:

• research question;
• method and sample;
• main findings;
• limitations;
• implications.

Keep correlation, causation, statistical confidence, and author interpretation distinct.

Multi-Source Synthesis

• Read all available sources before drafting.
• Organize by theme or question.
• Attribute disputed or source-specific claims.
• Surface conflicts in dates, measurements, definitions, or conclusions.
• Avoid presenting repeated claims as independent confirmation.

Compression Levels

• Snapshot: one paragraph or a few bullets.
• Brief: bottom line plus essential evidence and actions.
• Detailed: structured coverage of all major sections and caveats.

Scale by information density and user need, not page count alone.

Output Rules

• Do not invent context, intent, consensus, or causality.
• Preserve exact numbers and dates when they affect meaning.
• Use direct quotes only when wording itself matters and the source is available.
• Mark uncertainty with precise language.
• Distinguish source omissions from your own inability to access material.
• Keep recommendations separate from the summary unless the user requests them.

Optional Templates

Load summary-templates.md when a reusable output skeleton will save time. Adapt the template to the source instead of filling empty sections mechanically.

Final Check

• The opening states the most important conclusion or purpose.
• All critical figures, decisions, and caveats match the source.
• The summary is useful without pretending to replace unavailable evidence.
• The length and terminology fit the intended reader.
