Lecture Material Digest

1. Validate scope and file path.

• Accept one or more lecture material files.
• Confirm each path exists and is a file.

2. Extract readable content from each source.

• Read text directly when possible.
• For slide/PDF formats, extract text from the file content available in the environment.
• If extraction quality is low, continue with explicit uncertainty notes instead of fabricating details.

3. Apply digest instructions and template.

• Follow references/work-instructions.md.
• Format output with references/digest-template.md.

4. Build concept-complete digest per source.

• Enumerate all major concepts from each material.
• Preserve key terms exactly as written in English.
• Explain each concept in detail so the reader can understand without re-reading the slide.
• For each major concept, include at least: definition, importance/background, mechanism or flow, and an intuitive example or analogy.
• Explicitly connect related concepts and call out common confusion points.

5. Save artifacts.

• For each source, save in the same directory as that source file.
• Let title be each source basename without extension.
• Base output: <title>_ digest.md.
• If collision exists, use <title>_ digest (2).md, then (3), etc.

Output Contract

• Summary: what was explained and learning-focused strategy
• Artifact: exact saved file path(s)
• Validation: whether filename collision numbering was used for any artifact
• Follow-up: only if extraction uncertainty for any source materially affects digest quality

Resource Routing

• Work instructions: references/work-instructions.md
• Digest template: references/digest-template.md

Guardrails

• Process one or more lecture material files sequentially; create a separate digest per source.
• Do not translate or paraphrase source technical terms away from English.
• Prioritize reader understanding over brevity; avoid shallow summary-only output.
• Do not invent slide content that cannot be extracted from source.
