OpenMAIC is a multi-agent classroom platform that uses agents to plan, build, and revise interactive courses from prompts and uploaded materials. It is designed for immersive learning experiences and supports course components such as slides, quizzes, interactives, projects, images, video, voices, and PowerPoint imports, with catalogue skills covering its workflows.
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.

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 | $0.00070 | $0.02459 |
| Opus 5 | $0.00035 | $0.01229 |
| Sonnet 5 | $0.00014 | $0.00492 |
| Haiku 4.5 | $0.00007 | $0.00246 |
Grade A, and why
pro-editing 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Professional course editing
You are editing a persisted course, not generating one. The pages already exist in storage; your work is surgical — read what is there, change exactly what was asked for, and leave everything else untouched.
Enter the course before touching it
This skill is active because the course already has pages (the session is attached to an existing course, or the classroom was already built). Before any edit:
- Call
list_scenesto take stock of the whole course: every persisted page, its order, its type. This list — not your assumption — is the map you edit by. - Do not plan a replacement stage. The course has a structure; you are not replanning it.
- If the request is broad ("make it better"), turn it into a concrete plan against the page list and say which pages you will touch before touching them.
Read before every change
Read the target page with read_stage path:/scenes/<order|id>
immediately before editing it. The inventory it
returns — element ids, question ids, action ids, widget config — is the only
address space you may edit against, and it tells you the page's true type. A
stale id is a failed edit; a stale assumption about what is on the page is a
wrong edit. If an edit lands on the wrong page type, that is a signal to
re-read, not to force the operation.
read_stage has three levels, and a slide edit uses the deep one. The default
tree is a compact map — enough to find an element, never enough to edit it,
because it strips the styles. Before any slide write, read the page with
detail:"source": it returns the page's exact persisted JSON (all style
fields, raw content HTML with inline marks and line breaks, exact geometry,
z-order), and it is the root your patch paths address — a field read at
/content/canvas/elements/2/left is written back through that same path. It always
returns the whole page, so indices cannot drift between the read and the write.
detail:"text" is the third level: every text-bearing element as
{ path, id, type, text } plus a page-wide combinedText, for proving a page
carries no leftover copy.
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.
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.

pro-editing is a skill published in the GitHub repository THU-MAIC/OpenMAIC (32,590 stars, last pushed yesterday), licensed MIT. It adds 70 tokens to every session and 2,459 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

hr-onboarding
A new-hire onboarding plan as a single page — first week schedule, buddy + manager intro, learning track, equipment checklist, and "you're set when…" outcomes. Use when the brief mentions "onboarding", "new hire", "first week plan", or "入职".

Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context.
