Add Video to LazyPi
Use this skill for this repository only.
Invoke it with:
/skill:add-video <youtube-url>
Pi appends the command arguments to this skill as User: <args>.
Goal
Add a YouTube video to docs/_data/videos.yml with all metadata fetched automatically, inserted in the correct category and sorted in reverse chronological order. YouTube Shorts belong in the Short Pi category at the bottom of the videos page.
Step 1: Extract the video ID and detect Shorts
Parse the YouTube URL to extract the video ID.
Supported formats:
https://www.youtube.com/watch?v=VIDEO_IDhttps://youtu.be/VIDEO_IDhttps://www.youtube.com/shorts/VIDEO_ID
If the provided URL path contains /shorts/VIDEO_ID, mark the video as a Short. Shorts always go in the Short Pi category and do not require a category prompt.
Step 2: Fetch metadata via agent-browser
Use agent-browser to open the YouTube watch page and extract all four fields in a single session:
agent-browser open "https://www.youtube.com/watch?v=VIDEO_ID"
agent-browser eval "JSON.stringify({ title: document.querySelector('meta[name=title]')?.content || document.title.replace(/ - YouTube$/, ''), channel: document.querySelector('span[itemprop=author] link[itemprop=name]')?.getAttribute('content') || document.querySelector('meta[itemprop=channelId]')?.content, duration: document.querySelector('meta[itemprop=duration]')?.content, published: document.querySelector('meta[itemprop=datePublished]')?.content })"
The oEmbed API (https://www.youtube.com/oembed?url=URL&format=json) is a reliable fallback for title and author_name (channel) if agent-browser returns unexpected values. Use the original Shorts URL for the oEmbed URL when the provided URL was a Short.
Convert the raw values
duration — YouTube returns ISO 8601 (e.g. PT34M48S). Convert to M:SS or H:MM:SS:
PT9M24S → 9:24PT1H33M56S → 1:33:56PT0M38S → 0:38- Pad seconds to two digits always.
published — YouTube returns a full ISO 8601 timestamp (e.g. 2026-04-18T04:03:51-07:00). Truncate to the date portion only: 2026-04-18.
Step 3: Choose the category
If the provided URL is a Short, set the category to Short Pi and skip the user prompt.
For regular YouTube videos, read docs/_data/videos.yml to get the current categories in order, excluding Short Pi. Present them as a numbered list:
Which category should this video go in?
1. Intro to Pi
2. Full Course Pi
3. Advanced Pi
4. Slice of Pi
Enter a number:
Use AskUserQuestion (or equivalent interactive prompt) to get the user's choice. Accept the number only.
Step 4: Insert into the YAML
Read docs/_data/videos.yml. Find the chosen category block and insert the new video entry at the top of that category's videos: list (newest-first ordering). For Shorts, find the Short Pi category block.
Entry format:
- id: VIDEO_ID
title: "Video title here"
channel: Channel Name
duration: "M:SS"
published: "YYYY-MM-DD"
Do not quote channel unless it contains a colon or special character. Always quote title and duration. Always quote published.
Preserve all existing entries, whitespace style, and ordering in the file.
Step 5: Confirm
Tell the user what was added:
- video title
- channel
- duration
- publish date
- which category it was placed in
Notes
- Do not add a video that already exists in the YAML (check by
id before inserting).
- If agent-browser cannot fetch a field, ask the user for it rather than leaving it blank.
- The YAML file is the single source of truth — no other files need updating when adding a video.
Short Pi should stay as the final category in docs/_data/videos.yml so it appears at the bottom of the videos page.
