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.

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 | $0.00071 | $0.04821 |
| Opus 5 | $0.00036 | $0.02410 |
| Sonnet 5 | $0.00014 | $0.00964 |
| Haiku 4.5 | $0.00007 | $0.00482 |
Grade A, and why
obsidian-course-vault 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 11d 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.

Obsidian Course Vault
Use this skill when the user wants long-term course notes in Obsidian.
Assume commands run from this skill root. Otherwise use the absolute path to scripts/.
Core Boundary
- Let scripts handle vault structure, replay sync, replay diagnosis, cache refresh, tracker maintenance, and file writes.
- Let the agent handle course alignment, concept confirmation, terminology correction, graph interpretation, and final note prose.
- Do not let deterministic seed notes masquerade as finished course notes.
Main Commands
Initialize the vault:
python scripts\init_obsidian_course_vault.py --obsidian-dir "<obsidian-install-dir>" --vault-dir "<vault-dir>"
Add a course:
python scripts\add_course.py --vault-dir "<vault-dir>" --course-name "<course-name>"
Maintain a course or sync BUAA replay state:
python scripts\maintain_obsidian_course.py --vault-dir "<vault-dir>" --course-name "<course-name>" --course-page-url "<coursedetail-url>" --replay-output-dir "<replay-output-dir>"
Course Identity And Placement
Before adding or maintaining a BUAA course in a vault:
- Resolve
course-namefrom the extracted course title whenever possible. The normalized title is the course identity. - If the resolved title already exists in the vault, reuse that course folder. Same title means same course, even if the new
coursedetailURL has a differentcourse_id, lecturer, schedule, classroom, or sub_id range. - If the title is missing or unreliable, use the
course_idonly as a provisional course name such ascourse-136278, or ask the user for the intended title before writing formal notes. Do not infer the course from existing vault folders, teacher names, class times, or old extraction directories. - Interpret "use the previous vault" as selecting the vault root, not automatically selecting an existing course folder inside it.
- Keep each source
course_idand URL in sync metadata so multiple classroom sources can feed the same titled course without overwriting provenance.

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.

obsidian-course-vault is a skill published in the GitHub repository 1xiaoooo/buaa-course-skills (50 stars, last pushed 4mo ago), licensed MIT. It adds 71 tokens to every session and 4,821 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings.
