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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00125 | $0.02398 |
| Opus 5.5 | $0.00050 | $0.00959 |
| Sonnet 5.5 | $0.00025 | $0.00480 |
| Haiku 4.5 | $0.00013 | $0.00240 |
Grade A, and why
pptx-import 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 1mo 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 — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PPT import as appended pages of a stage
Fill an uploaded PowerPoint's slides INTO the stage the user created with
create_stage: the slides become appended pages (or pages inserted at
atOrder), keeping the original layout. The stage keeps its own title and its
existing pages — the PPT is content, not the classroom's identity. Import,
inspect and repair the pages, understand the course, then write
classroom actions. Do not skip from import to TTS.
The learner-facing name is 「PPT 导入成课」. Never say "clone", "style transfer", or "rewrite from the PPT".
Do not replan the imported deck. Do not call generate_scene on an
imported slide — that rebuilds the page and throws the original layout away.
Order (do not rearrange)
create_stagefor the classroom, then import the deck into it.- Roster.
- Inspect every page (read, and render when the tool exists). Load
pro-editingto fix visual bad cases. Do not patch/actionsyet. - From that inspection, form a course reading (what it teaches, page roles, flow). Then write actions page by page.
generate_tts.- Quiz / interactive only if the user asked.
Step 1 — create the stage, then import the deck
create_stagewith the classroom's own title and brief. The stage — not the PPT — is the classroom: import never changes its title.list_materials. Find the source.pptx(mat_id, mime or filename).- If several PowerPoints are attached, ask which one, unless the user already named it.
- Call
import_pptxwith that sourcemat_id and thestageIdfromcreate_stage. Pages append after the existing ones, numbered consecutively. PassatOrderto insert them at a position instead: pages at that order and beyond shift back. Existing pages are a normal premise — the PPT is one content source among others, never a reason to refuse. - A retry of the same material is idempotent — take the reused result and
continue from Step 2; do not re-parse. If the user wants the same PPT again
on purpose, delete its imported pages first (
edit_deckdelete), then retry. - Want pages beyond the deck (quiz, interactive, extra slides)? Insert a stub
with
edit_deckinsert, thengenerate_scenethat new page only with its explicittypeandbrief— do not re-import the deck to get more pages.
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.

pptx-import is a skill published in the GitHub repository THU-MAIC/OpenMAIC (41,328 stars, last pushed today), licensed MIT. It adds 125 tokens to every session and 2,398 once invoked, about $0.0005 per session on Opus 5.5. 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.
