Teaching Site Skills

Languages: English · 繁體中文 · 简体中文 · 日本語

---

A set of 11 agent skills (Anthropic Skills format) that capture the full workflow of building an interactive teaching site from scratch. The pipeline covers: outline design → content authoring → vanilla-JS SPA → interactions → visual assets → corporate-edition compression → ebook delivery, plus three cross-cutting skills: behavioral verification, content audit, and a visual design system.

Supports Claude Code, Codex, Antigravity (Gemini), Cursor, OpenCode, and 55+ AI coding agents — installed via the skills CLI. Claude Code is the primary development and test platform; other agents are statically compatible.

Distilled from a four-day workshop site (admin & finance AI automation), but every skill has been abstracted to a generic level — applicable to any “chaptered / multi-unit / with-materials” teaching site.

Structure: 1 super-skill + 10 sub-skills

After installation, the skills are unpacked into each agent’s skills directory (Claude Code: ~/.claude/skills/; Codex: ~/.codex/skills/; Antigravity: ~/.gemini/antigravity/skills/; others — see the skills CLI matrix):

/
├── teaching-site/                          ← ⭐ super-skill entry (with references/)
│   ├── SKILL.md                            ←   architecture + dispatch logic
│   └── references/                         ←   load-on-demand supplements
│       ├── consistency-checklists.md       ←   post-stage cross-file checks
│       ├── scenarios.md                    ←   common prompt → flow mapping
│       ├── troubleshooting.md              ←   failure-mode triage

├── course-outline-design/                  ← Stage 1  course outline
├── course-content-authoring/               ← Stage 2  content authoring
├── static-spa-conversion/                  ← Stage 3  SPA conversion
├── static-spa-interactions/                ← Stage 4  interactions
├── web-visual-assets/                      ← Stage 5  visual assets
├── course-corporate-edition/               ← Stage 5b corporate edition branch
├── course-ebook-publishing/                ← Stage 6  ebook delivery
│
├── web-visual-verification/                ← cross-cutting: behavioral verification (Playwright)
├── web-content-audit/                      ← cross-cutting: content audit
└── teaching-site-design-system/            ← cross-cutting: tokens, fonts, component visuals

Two trigger paths coexist:

• Address teaching-site with “build me a course site” → super-skill takes over, decides which sub-skill to dispatch.
• Address a sub-skill directly with “make an ebook” → triggers course-ebook-publishing, skipping orchestration.

Installation

Prerequisites: any supported AI coding agent (Claude Code, Codex, Antigravity, Cursor, OpenCode, …) and Node.js (npx ships with it).

One-line install via the skills CLI (same command on Windows / macOS / Linux):

npx skills add kevintsai1202/teaching-site-skills --all

The CLI auto-detects which agents are installed on your machine and writes to the corresponding skills directories. Restart the agent (or run its reload command — e.g. Claude Code’s /reload) and all 11 skills load automatically.

Important: the 11 skills cross-reference each other. Always pass --all to install them together; cherry-picking will break dispatch at runtime when a downstream skill is missing.

Targeting a specific agent (when auto-detection misses it, or you want to install only to one):

# Claude Code only   →  ~/.claude/skills/
npx skills add kevintsai1202/teaching-site-skills --all --agent claude-code

# Codex only         →  ~/.codex/skills/
npx skills add kevintsai1202/teaching-site-skills --all --agent codex

# Antigravity only   →  ~/.gemini/antigravity/skills/
npx skills add kevintsai1202/teaching-site-skills --all --agent antigravity

# Install to every supported agent (55+) at once
npx skills add kevintsai1202/teaching-site-skills --all --agent '*'

Other useful commands:

# List installable skills in the repo without installing
npx skills add kevintsai1202/teaching-site-skills --list

# Install only selected skills (not recommended — breaks the pipeline)
npx skills add kevintsai1202/teaching-site-skills --skill teaching-site --skill course-outline-design

Cross-agent note: this skill set has been end-to-end tested on Claude Code with a full 4-day workshop pipeline. Other agents are statically compatible — the CLI installs correctly and the frontmatter format is portable — but dispatch UX, trigger-phrase hit rate, and sub-skill auto-discovery vary across each agent’s skill-matching implementation. On first use with a new agent, run a “build me a course site” happy-path to verify.

Cross-cutting (callable from any stage):

Coordinator: teaching-site figures out which stage the user is at and dispatches the right sub-skill.

Common scenarios

“Build me a 4-day workshop site from scratch.” → teaching-site takes the lead and dispatches outline → content → SPA → interactions → visuals in order.

“I already have lecture notes in .md — turn them into a site.” → Jump straight to static-spa-conversion (skipping stages 1–2; structure is extracted from the existing markdown).

“The site is done — print me a PDF for the attendees.” → Confirm the site is stable, then call course-ebook-publishing directly.

“Compress this open-class into a 6-hour corporate edition.” → Call course-corporate-edition directly. Output is a single index.html (with embedded COURSE) plus a folder the client can zip.

“The site works, but the mobile view is terrible.” → Go directly to static-spa-interactions, then run web-visual-verification across viewports.

“Material link 404s,” “quiz score shows wrong,” “progress check stops syncing.” → Almost always a missed “three-way sync.” Call web-content-audit to diff filesystem / course-data.js / getMaterialUrl().

Key design decisions (why the skills are split this way)

1. Super-skill + sub-skills coexist: broad requests go through teaching-site orchestration; specific requests trigger sub-skills directly. Both trigger paths work.
2. Two-layer architecture — core pipeline + cross-cutting: the 7 core skills are sequential (stages 1–6); the 3 cross-cutting skills are callable from any stage.
3. Cross-file invariants live inside the sub-skill that owns them: e.g. “touching a quiz means syncing 5 hardcoded places” lives in content-authoring — co-located with the work that triggers it.
4. Verification and audit are deliberately split into two skills: different failure modes (verify blocks CI / audit always passes) and different cadences (every PR / release milestones).
5. The design system encodes the “why,” not just the “what”: values change (OKLCH tokens get tuned), but the reasoning usually doesn’t.
6. The corporate edition is reverse-engineered for delivery: window.COURSE embedded inline, an asset fallback chain (custom edition → main edition), and the ebook builder uses vm.runInContext to extract COURSE back out.
7. Ebook PDFs use Playwright page.pdf(), not Chrome CLI: because the CLI doesn’t support footerTemplate (no page numbers).
8. localStorage task-id keys must never be renamed: renaming after publish desyncs every attendee’s progress checkboxes.

Full reasoning lives in teaching-site/references/design-rationale.md.

Origin & license

Original implementation: ai-workshop — a 4-day workshop on admin & finance AI automation.

Skills were distilled, abstracted, and structured by Claude Opus 4.7 (with 1M context) on 2026-05-14 from the project’s history. The authoring pass read 30 git commits, 33 verify/diagnose/audit scripts, the CSS/JS sections of index.html (3000+ lines), and the 企業包班/ (corporate-edition) sub-directory.

Each skill is standalone markdown — no restrictions on use, modification, or redistribution. If you improve them, PRs back to the original repo are welcome.
