A tool for adding supporting files to a lecture session and including their contents in a course wiki. Supporting files can include PDFs, slide decks, word-processing documents, images, text, and code.

Use it to import supplementary files, convert supported documents to Markdown, copy images or text files, and update the course wiki index.

It adds handouts and other materials without repeating lecture transcription or downloading slides again.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add WALKERKILLER/Look-Tongji-Notes --skill add

Clone the repo

git clone --depth 1 https://github.com/WALKERKILLER/Look-Tongji-Notes

Made for: Claude Code.

Or install look-tongji-notes, the plugin that ships this one along with the rest of its 11 skills.

Per session 42 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 398 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00042	$0.00398
Opus 5	$0.00021	$0.00199
Sonnet 5	$0.00008	$0.00080
Haiku 4.5	$0.00004	$0.00040

Measured 9d ago against content hash 01c34a6c5f06, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

add scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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

Import materials:

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

The CLI copies files into the session's materials/<name>/ directory.
MarkItDown auto-converts supported formats to Markdown.
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/).

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
