Add

Add Materials

Attach supplementary materials to a lecture session.

When to Use

• User says /add or "add this material to the course".
• After transcribing a lecture, adding additional PDFs/PPTs/docs.
• User wants materials indexed into the wiki without re-running transcription.

Workflow

1. Import materials:

python "<SKILL_DIR>/../../scripts/look_tongji.py" add \
  --course-id "<ID>" --sub-id "<ID>" \
  --material "handout=/path/to/file.pdf"

2. The CLI copies files into the session's materials/<name>/ directory.
3. MarkItDown auto-converts supported formats to Markdown.
4. The course wiki index is updated automatically.

Supported Formats

• PDF (.pdf), PPTX (.pptx), DOCX (.docx) — via MarkItDown
• Images (.png, .jpg, .webp) — copied as-is
• Text/Code (.txt, .md, .py, .js) — copied as-is

Difference from /note --material

/add only imports materials + updates the index. It does NOT trigger transcription or slide download.

Where <SKILL_DIR> Points

<SKILL_DIR> is the directory containing this SKILL.md. Shared scripts (look_tongji.py, timeline_tools.py, tongji_backend/) and references live two levels up in the repository root (<SKILL_DIR>/../../scripts/ and <SKILL_DIR>/../../references/).
