Course Content Authoring

Course Content Authoring

Schema authority: all primitive field names (unit / concept / prompt / task / material / quiz / faq / illustration) come from `_shared/domain-primitives.md`. When this skill mentions a field, that file is the source of truth.

>

Filename convention (English-first): all generated files and directories use English names. The mapping from legacy Chinese names is in _shared/domain-primitives.md §0.

This skill produces the teaching substance of a course: the things a learner reads, copies, listens to, or works through. It anchors every artifact to the outline IDs from course-outline-design, so the next stage (SPA conversion) can wire them up mechanically.

Material Types (Pick What Fits Your Course)

The example workshop uses these — they're examples, not requirements. Decide per course what makes sense:

About prompt templates: This skill is agnostic to which prompt framework you use. RTFC (Role / Task / Format / Context) was used in the original workshop, but if your course teaches a different framework (e.g. CRISPE, COSTAR, plain examples), use that. Don't force RTFC into a course where it doesn't fit. The framework is part of the course content, not a property of this skill.

CSV Trap (Easy to Miss)

When generating CSV files that will be opened in Excel by non-developer learners, prepend a UTF-8 BOM ():

const content = '' + headerRow + '\n' + dataRows.join('\n');

Without it, Excel on Windows mis-detects encoding and shows mojibake. Learners will think the file is broken. This bug was found late in the example workshop — bake it in from the start.

Anchor Everything to Outline IDs

Every artifact you produce must trace to a unit ID. Use this header pattern in lecture notes:

## u-3: {Unit title from outline.md}

**對應任務**: d2-u3-t1, d2-u3-t2
**對應素材**: 客訴處理SOP.md, FAQ官方版.md
**圖片需求 (illustrations)**:
- `day2-u3-hero.png` — hero / 主視覺：{學員角色} 在 {情境} 操作的場景圖（AI 生圖）
- `day2-u3-flow.svg` — 概念流程：{步驟 A → B → C}（手繪 SVG，含中文標籤）
- `day2-u3-example.png` — 結果範例截圖（選填）

{lecture content here}

Why: the SPA conversion stage will read these markers to auto-link tasks, materials, content, and visual asset slots. If you skip them, the SPA author has to re-read everything to figure out the wiring, and Stage 5 (web-visual-assets) has no spec to generate against — you end up with a site that has only a cover image.

Task IDs Are Forever

When writing task descriptions inside content.md, assign each task a stable ID (e.g. d2-u3-t1). These IDs will become localStorage keys in the deployed website. Three rules:

1. Never rename a published task ID. Students' progress is keyed to it. 2. Never reuse a deleted task ID. If you remove a task, the ID retires permanently. 3. Two formats coexist in practice (d{n}-u{m}-t{k} and day{n}-u{m}-t{k}). Pick one for new content; don't mix.

Quiz Item Discipline

If the course has a quiz, write items numbered sequentially (q1, q2, ...). Be aware these numbers will leak into multiple places once on the SPA:

• The quiz array itself
• A qIndexToDay()-style helper that maps each item to its source chapter (so wrong answers can link back)
• Hardcoded strings in the SPA: "結訓測驗（N題）", score display — / N, passing threshold s >= K

Renumber-safe authoring: think of the quiz as append-only. If you delete q3, leave the slot empty in your draft and renumber only at the very last stable moment, with a checklist of all the places to update.

Hidden Materials Pattern

Some materials are for instructors only (answer keys, pre/post-test scoring) or conditional (only shown if a feature flag is on). Mark them explicitly in materials/README.md:

| 素材 | 對象 | 備註 |
|---|---|---|
| 員工差勤辦法.md | 學員 | Day 2 公開素材 |
| 結訓測驗解答.md | 講師 | 不要納入 SPA materials[]，僅講師端使用 |

The SPA conversion stage will read this column and exclude instructor-only items.

Anti-Patterns

• Writing content before outline is locked — every back-edit cascades to multiple files.
• Embedding prompt frameworks the course doesn't actually teach — if your course doesn't use RTFC, don't force-fit it just because the example template has it.
• Quiz items without source-chapter mapping — when a learner gets one wrong, they need to know where to review. Tag every quiz item with the unit it came from.
• Long flat material list with no instructor / learner distinction — by Day 4 the instructor doesn't know which file is what.
• Forgetting CSV BOM — see above.

Completion Gate (Hard Rule — must pass before hand-off)

Before declaring "content draft complete" and suggesting static-spa-conversion, every item below must have a written artefact in the corresponding .md file (not just a verbal "yes"). Walk the user through them; if an artefact is thin or missing, ask one clarifying question and finish it before moving on.

1. Per-day `content.md` exists for every Day declared in overview.md 每日主題 table. A Day file with only the title heading fails — it must contain unit sections. 2. Every outline unit ID has a matching `## u-{id}` section in its day's content.md. Run a quick diff: list of unit IDs in day{n}/outline.md must be a subset of ## u- headings in day{n}/content.md. Missing sections fail the gate. 3. Every unit section has substance — at least one of: lecture script ≥ ~10 lines, **對應任務** listing real task IDs, **對應素材** listing real material filenames. A unit that only has a heading + TODO placeholder fails. 4. Every unit section declares `圖片需求 (illustrations)` with 1–3 entries. Each entry must specify (a) filename stem (e.g. day2-u3-hero.png), (b) image kind (hero / diagram / screenshot / scene), (c) one-line spec for the visual asset author. Units that genuinely need no image must declare a single waiver line: - waived: {reason, e.g. 5-min admin slot}. Silence does not pass. 5. Quiz items (if applicable) tagged with `sourceUnit` — every q* item points to a real unit ID so wrong answers can route students back to the source chapter. Untagged items fail. 6. `materials/README.md` exists with the material index, distinguishing 學員 vs 講師 columns (see Hidden Materials Pattern above).

If the user pushes "可以了，先轉成網頁" before all items have written artefacts, refuse politely:

「Stage 2 還有 N 個單元沒寫實質內容（或沒設圖片需求）。直接進 Stage 3 會生出薄殼網頁，學員看到只有標題 + 沒插圖。先把第 X 項補上，大概 Y 分鐘，比之後重做網頁省好幾倍。」

If the user explicitly demands a thin demo (與 teaching-site Stage 2 Override Policy 相同條件)：依照 orchestrator 文件的三步驟（標 stub 註解、設 __thinDemo: true、明確告知學員顯示效果）才放行，不要在 Stage 2 內部偷偷放水。

Hand-off

When this stage finishes (Completion Gate passed), you should have:

• Per-day content.md filled in, every outline unit ID covered by a ## u-{id} section
• Each unit section: lecture script + tasks + materials refs + 圖片需求 (illustrations) 1–3 entries
• All material files in materials/ with an index README distinguishing 學員 / 講師 items
• Quiz draft (if applicable) numbered q1..qN with sourceUnit source-chapter tags
• Every artifact traceable to an outline unit ID

Tell the user: "content draft complete. Next stage (static-spa-conversion) will convert this into course-data.js + index.html, including an illustrations: [] array per unit derived from your 圖片需求 blocks. After Stage 3/4, web-visual-assets will fulfil those slots — your spec lines become its prompt input. Don't change unit IDs or task IDs from this point — they'll become localStorage keys."
