Keats Course Downloader

KEATS Course Downloader

Use this skill when a user provides a KEATS course URL and either a cookie file or a Playwright auth-state JSON file, and wants the course content downloaded locally into per-section folders.

Quick Start

The bundled one-command entrypoint accepts either a raw cookie file or a Playwright auth-state.json file.

Cookie-file mode:

"$HOME/.codex/skills/keats-course-downloader/scripts/download-keats-course.sh" \
  "https://keats.kcl.ac.uk/course/view.php?id=134598" \
  "/absolute/path/to/cookies.txt"

Auth-state mode:

"$HOME/.codex/skills/keats-course-downloader/scripts/download-keats-course.sh" \
  "https://keats.kcl.ac.uk/course/view.php?id=134598" \
  --auth-state "/absolute/path/to/auth-state.json"

Optional third argument overrides the output directory:

"$HOME/.codex/skills/keats-course-downloader/scripts/download-keats-course.sh" \
  "https://keats.kcl.ac.uk/course/view.php?id=134598" \
  "/absolute/path/to/cookies.txt" \
  "/absolute/path/to/output"

For auth-state mode, the output directory is the optional fourth argument:

"$HOME/.codex/skills/keats-course-downloader/scripts/download-keats-course.sh" \
  "https://keats.kcl.ac.uk/course/view.php?id=134598" \
  --auth-state "/absolute/path/to/auth-state.json" \
  "/absolute/path/to/output"

Cookie File Format

The cookie file must contain a single raw Cookie header string, for example:

MoodleSession=abc123; other_cookie=value; another_cookie=value2

Do not ask the user to paste sensitive cookies into chat if a local file path will do.

Auth State Format

auth-state.json should be a Playwright storage_state JSON file containing a top-level cookies array. The downloader extracts cookies for keats.kcl.ac.uk and builds the request session automatically.

Use browser automation to help the user reach the KEATS course page and complete SSO/MFA interactively, then prefer a saved Playwright auth state over asking the user to manually copy cookies.

To capture or refresh an auth state interactively:

"$HOME/.codex/skills/keats-course-downloader/scripts/capture-keats-auth-state.sh" \
  "https://keats.kcl.ac.uk/course/view.php?id=134598" \
  "/absolute/path/to/auth-state.json"

This opens a headed browser. The user completes KEATS SSO/MFA manually, then returns to the terminal and presses Enter after the course page is visible.

Dependencies

Run Python through uv; do not ask the user to install packages manually unless uv itself is unavailable.

The download wrapper uses:

uv run --with requests --with beautifulsoup4 python scripts/download_keats_course.py

The auth-state capture wrapper uses:

uv run --with playwright python scripts/capture_keats_auth_state.py

If Playwright is not already cached, uv may download the Python package on first run. The capture flow requires a headed browser because the user must complete KEATS SSO/MFA manually.

If running directly from a cloned copy of this repository before installing the skill, replace $HOME/.codex/skills/keats-course-downloader with the local keats-course-downloader directory.

Workflow

1. Confirm the course URL and either a cookie file path or an auth-state file path.
2. If no valid auth-state or cookie file exists, run scripts/capture-keats-auth-state.sh.
3. Run scripts/download-keats-course.sh.
4. Check the generated manifest.json and section directories.
5. If the download fails with login or redirect issues, assume the cookies are expired or incomplete and ask the user to refresh auth state.

Behavior

The bundled Python script:

• fetches the course page with the provided cookies
• parses course sections such as Week, Topic, or other section headings that contain resources
• downloads file resources into per-section folders
• resolves KEATS URL activities and stores the final external link in .url.txt
• writes manifest.json and README.txt into the output directory

Files

• Wrapper: scripts/download-keats-course.sh
• Downloader: scripts/download_keats_course.py
• Auth-state capture wrapper: scripts/capture-keats-auth-state.sh
• Auth-state capture script: scripts/capture_keats_auth_state.py

Prefer the wrapper unless you need to change Python-level flags directly.
