Iblai Vibe Course Create

/iblai-vibe-course-create

Overview

This skill drives the IBL.AI Course Creation API to programmatically produce courses on an OpenEdX deployment. The API combines AI-generated structure (sections → subsections → units → components) with direct EdX writes, so EdX is the single source of truth for every structural operation. There are no intermediate database models for sections, subsections, units, or components — the API proxies every read/write to EdX.

Two workflow styles are supported:

1. Stepwise (recommended for agents) — create the task, create the empty course on EdX, generate the outline, review, edit structure if needed, draft unit content, verify, publish.
2. Automated pipeline — one call (/start/) runs the entire pipeline as a background Celery task; the agent polls for completion.

Prefer stepwise when the agent (or a user) wants to review or modify intermediate output. Prefer the pipeline when the brief is tight and no human-in-the-loop review is expected.

Configuration

All endpoints are rooted at:

{base_url}/api/ai-mentor/orgs/{org}/users/{user_id}/

Every request MUST include:

Authorization: Api-Token {api_key}
Content-Type: application/json   (for JSON bodies)

EdX Block Hierarchy (critical)

Course
└── Section       (chapter)
    └── Subsection    (sequential)
        └── Unit          (vertical)
            └── Component   (html | problem | video)

Each block has an xblock_id EdX locator:

block-v1:{org}+{course}+{run}+type@{type}+block@{slug}

The segment type@<type> identifies the block kind: course, chapter, sequential, vertical, html, problem, video. Parent/child relationships are enforced by the API:

Violating hierarchy returns 400.

What the generated course looks like in edX Studio (course outline and a single unit with components):

Task Lifecycle

A CourseCreationTask stores the generation brief and tracks progress. Its status transitions:

Pending → Scheduled → In Progress → Success | Failed | Cancelled

• Pending after POST /tasks/
• Scheduled after GET /tasks/{id}/start/
• In Progress while the Celery worker runs
• Success once the outline + content + publish have all completed
• Failed on any unrecoverable error (check task detail for error / reason)

Request Payloads

Create task (POST /course-creation/tasks/)

{
  "name": "Introduction to Python Programming",
  "description": "A beginner-friendly course covering Python fundamentals: variables, primitive data types, control flow (if/else, for, while), functions, error handling, and basic data structures (lists, tuples, dicts, sets). Emphasize hands-on coding with small, runnable exercises. Avoid object-oriented programming — that belongs in a follow-up course.",
  "target_audience": "First-year undergraduates with no prior programming experience. English is a second language for ~40% of the cohort.",
  "publish_course": true,
  "provider": "openai",
  "model": "gpt-4o-mini",
  "desired_number_of_sections": 4
}

Create xblock (POST /course-creation/course/{course_id}/create-xblock/)

{
  "parent_xblock_id": "<parent locator>",
  "xblock_type": "section | subsection | unit | html | problem | video",
  "display_name": "Readable title",
  "content": "<optional, only for html/problem/video>",
  "position": "last"
}

html content is HTML. problem content is EdX OLX problem XML. video accepts HTML wrapping a video embed.

Update xblock

{
  "xblock_id": "<locator>",
  "display_name": "Optional new title",
  "content": "<optional, only for html/problem>"
}

Omit either field to leave it unchanged. Sending neither returns 400.

Delete xblock

{ "xblock_id": "<locator>" }

Deletions cascade (section → subsections → units → components) and are irreversible.

Reorder children

{
  "xblock_id": "<parent locator>",
  "children": ["<child locator 1>", "<child locator 2>", "..."]
}

You must list every current child. To move a block to a different parent, include it in the new parent's children array — EdX will detach it from its former parent automatically.

Recommended Workflow (Stepwise)

1. POST   /course-creation/tasks/                                      → task_id
2. POST   /course-creation/tasks/{task_id}/create-course/              → course_id, course xblock_id
3. POST   /course-creation/tasks/{task_id}/create-course-outline/      → sections/subsections/units on EdX
4. GET    /course-creation/course/{course_id}/full-structure/          → review generated structure
5. (Optional) create/update/delete/reorder xblocks to fix the outline
6. GET    /course-creation/course/{course_id}/draft-content-for-all-units/  → background content drafting
7. Poll /full-structure/?include_content=true until every unit has components
8. (Optional) update individual components via /update-xblock/
9. POST   /course-creation/course/{course_id}/sync-to-edx/             → publish

Polling for content completion

/draft-content-for-all-units/ is asynchronous. Poll either the task status (GET /tasks/{task_id}/) or re-fetch /full-structure/?include_content=true and check that every unit's components array is non-empty. A typical course (3–5 sections, ~15 units) takes 1–3 minutes.

Back-off pattern: start at 20s, double up to 120s, cap at 5 minutes total wait before surfacing a timeout to the user.

Alternative: Fully Automated Pipeline

1. POST /course-creation/tasks/                → task_id
2. GET  /course-creation/tasks/{task_id}/start/
3. Poll /course-creation/tasks/{task_id}/      → wait for status == "Success"
4. GET  /course-creation/course/?task={task_id}→ resolve course_id

Use this only when the user explicitly asks for a "one-shot" course and does not want to approve the outline.

File Attachments (reference material)

Upload up to 4 files, 20 MB each, via multipart to /course-creation/files/:

POST /course-creation/files/
Content-Type: multipart/form-data

course_creation_task=<task_id>
file=<binary>

Supported content: PDFs, Word docs, Markdown, plain text, slide decks. The AI uses these as reference when generating outline and unit content. Upload files before calling create-course-outline or start — files attached later are ignored.

Best Practices for Writing the Course Brief

The quality of description and target_audience dominates output quality. Before calling POST /tasks/, draft the brief following the template below. If the user's brief is vague, ask clarifying questions first — do not send an underspecified task, because outline regeneration is wasteful.

The 5-field brief template

1. Subject & scope — what is in, and (explicitly) what is out.
2. Learning outcomes — 3–7 verbs-as-outcomes ("by the end, users can build, diagnose, compare…").
3. Target audience — prior knowledge, language level, motivation, typical study time/week.
4. Pedagogy — tutorial vs. project-based vs. assessment-heavy; how much theory vs. practice.
5. Format constraints — number of sections, approximate length, any required topics.

Good vs. weak briefs

Weak (produces generic, thin course):

description: "A course on Python." target_audience: "Beginners."

Strong (produces coherent, teachable course):

description: "A project-based introduction to Python 3.11 focused on data-wrangling for non-engineers. Cover variables, control flow, functions, file I/O, and the csv + json modules. Every section ends with a mini-project using a realistic dataset (airline delays, climate records). Exclude object-oriented programming, decorators, async, and type hints — a follow-up course covers those. Use an encouraging, low-jargon tone." target_audience: "Working analysts (marketing, ops, journalism) with spreadsheet fluency but no programming background. ~4 hours/week, 6 weeks total."

Refinement rules (apply before submitting the task)

• State exclusions explicitly. LLMs over-include. Saying "do not cover OOP" is more effective than listing only what to include.
• Convert vague adjectives into measurable ones. "Beginner" → "assumes high-school algebra, no coding"; "advanced" → "assumes 2+ years professional experience with X".
• Name the artefact type. "Tutorial course with hands-on exercises", "exam-prep course with graded quizzes after every subsection", "capstone course culminating in a single graded project".
• Right-size desired_number_of_sections. 3 = short workshop, 4–5 = term course, 6–8 = bootcamp. Going above 8 usually produces weak sections.
• Pick the model to match complexity. gpt-4o-mini is fine for most intro courses; use gpt-4o / gpt-4.1 when the description mentions formal reasoning, technical depth (graduate-level math, law, medicine), or multiple cross-referenced modules.
• Attach reference files for domain specificity. If the course must align with a textbook, syllabus, curriculum standard, or style guide, upload it. One good PDF outperforms several paragraphs of description.

Clarifying-question checklist

If any of these is unknown after the user's initial brief, ask before creating the task:

1. Who is the user? (background + motivation)
2. What should they be able to do by the end?
3. How long is the course? (weeks, sections, hours)
4. Tutorial, assessment-heavy, or project-based?
5. Any topics to exclude or must-cover topics?
6. Reference material to upload?
7. Publish immediately or keep in draft?

Reviewing AI Output

After the outline (step 3) and again after content drafting (step 6), always pull /full-structure/?include_content=true and verify:

• Every unit has ≥1 component. Empty units are a drafting failure — re-run draft-content-for-unit for that locator.
• Section/subsection titles are non-redundant. LLMs sometimes produce "Introduction" as both section 1 and section 1's first subsection — rename via update-xblock.
• Assessment problems have valid OLX. Open the content field; it must contain a <problem>…</problem> wrapper with at least one response input. Malformed OLX silently fails on publish.
• HTML components don't leak prompts. Look for telltale phrases ("As an AI…", "Here is the lesson…"). If found, re-draft that unit.
• Total length is coherent. A course targeted at 4 hours/week for 6 weeks should have roughly 24 units of substantive content; adjust by adding/removing sections.

Error Handling

Guardrails

• Never publish without review. Always fetch /full-structure/?include_content=true and confirm with the user before calling sync-to-edx — published EdX courses are visible to enrolled students and costly to retract.
• Don't mass-delete. delete-xblock on a section is irreversible and cascades. Confirm target before calling.
• Respect file limits. Max 4 files per task, 20 MB each. Over-limit uploads are rejected with 400.
• Tenant isolation. org and user_id must match the authenticated user's platform and username — cross-organization requests return 403. Do not attempt to create courses in an organization different from the caller's.
• Do not leak the API key. Treat api_key as a bearer secret; never echo it in responses, logs, or committed files.
• Background tasks can fail silently to the caller. After /start/ or /draft-content-for-all-units/, always verify downstream (status polling, full-structure fetch) rather than trusting the 202/200 response.
• Ask before picking a larger/more expensive model. gpt-4o/gpt-4.1 cost materially more than gpt-4o-mini. Confirm with the user when complexity warrants it; otherwise default to gpt-4o-mini.
