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 | $0.00104 | $0.02202 |
| Opus 5 | $0.00052 | $0.01101 |
| Sonnet 5 | $0.00021 | $0.00440 |
| Haiku 4.5 | $0.00010 | $0.00220 |
Grade A, and why
stage-dsl 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 — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.
The stage document map
This is a map, not the field manual.
Use it to decide which subtree owns a value, which path to read, and which reference chapter to load. Then read the exact source before writing.
The document model
The durable structure is:
stage
├── outline
└── scenes[] ordered by scene.order, shown as pages 1..N
├── id stable scene identity
├── order 1-based page position
├── type slide | quiz | interactive | pbl
├── content shape selected by scene.type
│ ├── slide.canvas
│ ├── quiz.questions[]
│ ├── interactive.html / widgetConfig
│ └── pbl.projectV2
└── actions[] ordered playback verbs
stage is the stage's metadata. outline is the generation plan. A persisted page
is a scene. Its type and content.type must agree.
The three generic tools do not replace page-list operations. Insert, delete,
reorder, and retitle pages with edit_deck.
Tool vocabulary
| Need | Tool | How |
|---|---|---|
| Read a scene | read_stage |
`path:/scenes/<order |
| Edit scene content or actions | patch_stage |
`target:/scenes/<order |
| Search visible text or source | grep_stage |
literal search over the whole stage |
| List stages in folders | list_folder_stages |
returns the explicit stageId required by every stage tool |
| Insert, delete, reorder, or retitle pages | edit_deck |
page-list operations stay outside the document patcher |
| Plan and build a new stage | conversation + create_stage + generate_scene |
settle the page plan in conversation, then call generate_scene once per page with an explicit brief |
| Set the classroom cast | set_roster |
write the settled roster before page generation |
Addressing with read_stage
| Path | Resolves to |
|---|---|
"" or omitted |
the whole stage |
/outline |
the persisted outline snapshot |
/scenes/3 |
the scene whose order is 3 |
/scenes/scene_abc |
the scene with that stable id |
/scenes/scene-abc |
the historical hyphenated scene-id form |
/scenes/3/actions |
only scene 3's action array |
What ships with it
4 files 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.

stage-dsl is a skill published in the GitHub repository THU-MAIC/OpenMAIC (33,238 stars, last pushed yesterday), licensed MIT. It adds 104 tokens to every session and 2,202 once invoked, about $0.0005 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.
