OpenClaw 评估

The skill is internally consistent with its stated purpose (a wrapper for the dedao-dl CLI) but installs a remote binary from GitHub without checksum verification and expects sensitive login cookies/QR login from the user — exercise normal caution.

# dedao-dl

This skill guides the agent in using the `dedao-dl` CLI tool to interact with the Dedao (得到) app content.

## Initialization

**MANDATORY FIRST STEP:** Before using any `dedao-dl` commands for the first time, you MUST run the installation script and verify the CLI is available.

Run the script to download the latest binary for the current OS:
```bash
python scripts/install_dedao_dl.py
```
After installation, you should ALWAYS use the helper script `scripts/run_dedao.py` to execute commands instead of running the raw `dedao-dl` executable. The helper script cleans up the CLI's terminal formatting, making the output directly readable by you without needing to redirect it to text files.
Example: Use `python scripts/run_dedao.py -h` instead of `./dedao-dl -h`.

## Prerequisites & Login

Before downloading any content, ensure the user is logged in:
- Command: `python scripts/run_dedao.py login -q` (QR code login) or `python scripts/run_dedao.py login -c "<cookie_string>"`
- Verify current user: `python scripts/run_dedao.py who`
- List logged-in users: `python scripts/run_dedao.py users`
- Switch user: `python scripts/run_dedao.py su`

Dependencies for specific formats (inform the user if they are missing):
- PDF generation requires `wkhtmltopdf`
- Audio generation requires `ffmpeg`
- Markdown requires no additional dependencies

## General Workflow

For any content download, the typical two-step workflow is:
1. List the specific type of content to find its `ID`.
2. Use the corresponding download command with the `ID` and format flag (`-t`).

## Key Workflows & Commands

### 1. Courses (专栏/课程) & Free Content (免费专区)
- **List purchased courses**: `python scripts/run_dedao.py course`
- **List free courses**: `python scripts/run_dedao.py free` (Returns `EnID` strings instead of integer `ID`s)
- **List articles in a course**: 
  - For purchased courses (using integer ID): `python scripts/run_dedao.py course -i <course_ID>`
  - For free courses (using EnID): `python scripts/run_dedao.py article -c <course_EnID>`
- **Download a single article (RECOMMENDED)**: `python scripts/run_dedao.py dl <course_ID_or_EnID> <article_ID> -t <format>`
- **Download a full course**: `python scripts/run_dedao.py dl <course_ID_or_EnID> -t <format> [options]`
  - **WARNING: NEVER download a full course (only 1 parameter) without explicit user permission. Full downloads can take hours, consume massive disk space, and trigger anti-bot bans.**
  - Formats (`-t`): `1` (MP3), `2` (PDF), `3` (Markdown, **DEFAULT FOR THE AGENT**)
  - Options for Markdown (`-t 3`): `-m` (merge into one file), `-c` (include hot comments)
  - Prefix ordering: `-o` (adds index prefix like `00x.`)
  *Note: When downloading as PDF, be aware of rate limits ("496 NoCertificate"). Add sleep intervals if scripting.*

### 2. E-Books (电子书)
- **List e-books**: `python scripts/run_dedao.py ebook`
- **Download an e-book**: `python scripts/run_dedao.py dle <ebook_ID> -t <format>`
  - Formats (`-t`): `1` (HTML, default), `2` (PDF), `3` (EPUB), `4` (Markdown Notes)
- **View e-book notes**: `python scripts/run_dedao.py ebook notes -i <ebook_ID>`
- **Export e-book notes**: `python scripts/run_dedao.py dle <ebook_ID> -t 4` (Downloads notes as Markdown)

### 3. Audiobooks (每天听本书)
- **List audiobooks**: `python scripts/run_dedao.py odob`
- **Download audiobook audio/text**: `python scripts/run_dedao.py dlo <audiobook_ID> -t <format>`
  - Formats (`-t`): `1` (MP3), `2` (PDF), `3` (Markdown, **DEFAULT FOR THE AGENT**)

### 4. Other Content
- **List all categories & stats**: `python scripts/run_dedao.py cat`
- **List 'JinNang' (锦囊)**: `python scripts/run_dedao.py ace`
- **List recommended topics (知识城邦)**: `python scripts/run_dedao.py topic`

## Execution Guidelines

- Always check `python scripts/run_dedao.py -h` or `python scripts/run_dedao.py <command> -h` if unsure of the exact arguments.
- Always retrieve the correct `ID` first before executing a download command. **Make sure you use the list command corresponding to the content type you want to download (e.g., `course` ID for `dl`, `ebook` ID for `dle`, `odob` ID for `dlo`). Do not mix up IDs across categories.**
- **NEVER download an entire course (e.g. `python scripts/run_dedao.py dl <course_ID_or_EnID>`) unless the user explicitly asks you to.** Many courses have hundreds of articles which can lead to account bans.
- **ALWAYS favor downloading a single article**: First list the course articles using `course -i <course_ID>` or `article -c <course_EnID>`, find the specific article ID, and use `python scripts/run_dedao.py dl <course_ID_or_EnID> <article_ID>`.
- **DEFAULT FORMAT**: Whenever you download content using `dl` or `dlo`, default to using `-t 3` (Markdown) unless the user explicitly asks for MP3 or PDF. Markdown is safer, faster, and easier to read.
- When generating markdown for a whole course (if permitted by the user), consider using `-m` to consolidate files unless the user explicitly asks for individual files.
