# Yt Upload > Upload to YouTube and manage existing videos using the YouTube Data API v3. Use this instead of Blotato for any long-form YouTube work — Blotato cannot expose the tags field, cannot edit existing videos, and cannot post comments. - Skill: `tylerprogramming/yt-upload` (Agent Skill, multi-file: 5 files) - Install (CLI): `npx skillmds@latest add tylerprogramming/yt-upload` - Raw SKILL.md: https://api.skillmd.com/api/skills/tylerprogramming/yt-upload/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Integrations & APIs - Author: tylerprogramming (https://skillmd.com/u/tylerprogramming) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tylerprogramming/yt-upload --- Upload to YouTube and manage existing videos using the YouTube Data API v3. Use this instead of Blotato for any long-form YouTube work — Blotato cannot expose the tags field, cannot edit existing videos, and cannot post comments. ## Setup Check The skill reuses your existing Google OAuth client at `~/credentials.json` (same one Drive and Gmail use). The first run will need to authorize the YouTube scopes — that's a one-time browser flow. ```bash python3 ~/.claude/skills/yt-upload/yt.py auth ``` A browser opens, you approve both scopes (`youtube.upload` + `youtube.force-ssl`), token saves to `~/.claude/skills/yt-upload/token.json`. If you see "missing OAuth client" error: `~/credentials.json` was deleted. Tell the user to re-export from Google Cloud Console. ## Subcommands All actions go through one CLI: `python3 ~/.claude/skills/yt-upload/yt.py [args]`. Outputs JSON on stdout for downstream parsing. ### upload — schedule or publish a long-form video ```bash python3 ~/.claude/skills/yt-upload/yt.py upload \ --video "/Users/tylerreed/Downloads/claude design in 23 minutes.mp4" \ --title "Claude Design + Claude Code: Prompt to Live URL in 23 Minutes" \ --description-file ~/content/youtube/claude-design/description.md \ --tags-file ~/content/youtube/claude-design/tags.txt \ --thumbnail ~/content/youtube/claude-design/thumbnail-final.jpg \ --category 28 \ --privacy private \ --publish-at 2026-04-26T13:00:00-04:00 ``` - `--privacy private --publish-at ` schedules. YouTube auto-flips to public at that time. - `--privacy public` (without `--publish-at`) publishes immediately. - `--privacy unlisted` for share-link-only. - `--no-notify` to skip subscriber notifications. Default is to notify. - `--made-for-kids` if applicable. Default is no. - Categories: 22 = People & Blogs, 27 = Education, 28 = Science & Technology (default for tech tutorials). - Tags: pass via `--tags "tag1,tag2,..."` OR `--tags-file path` (comma-separated or one per line). YouTube caps the field at 500 chars total — script auto-truncates from the end and warns. The description file should be plain text. If you have a `description.md` with a markdown H1 and `---` frontmatter, strip those before passing — or pass the body section only. ### update — edit metadata on an already-uploaded video ```bash python3 ~/.claude/skills/yt-upload/yt.py update VIDEO_ID --title "New title" python3 ~/.claude/skills/yt-upload/yt.py update VIDEO_ID --description-file new.md python3 ~/.claude/skills/yt-upload/yt.py update VIDEO_ID --tags-file tags.txt python3 ~/.claude/skills/yt-upload/yt.py update VIDEO_ID --privacy public python3 ~/.claude/skills/yt-upload/yt.py update VIDEO_ID --publish-at 2026-05-01T13:00:00-04:00 ``` Only specified fields are updated; everything else is preserved (the script reads current snippet/status first). ### thumbnail — replace thumbnail on a published video ```bash python3 ~/.claude/skills/yt-upload/yt.py thumbnail VIDEO_ID --image ~/content/youtube/claude-design/thumbnail-backup-A.jpg ``` Image must be JPG or PNG, under 2 MB. If your source thumbnail is bigger: ```bash sips -s format jpeg -s formatOptions 80 input.png --out output.jpg ``` ### comment — post a top-level comment or reply ```bash # Top-level comment on a video python3 ~/.claude/skills/yt-upload/yt.py comment VIDEO_ID --text "🎯 link to my Skool community in the description!" # Reply to a specific comment python3 ~/.claude/skills/yt-upload/yt.py comment --reply-to COMMENT_ID --text "thanks!" ``` ### list — list my recent uploads ```bash python3 ~/.claude/skills/yt-upload/yt.py list --max 10 ``` Returns JSON array with video_id, title, published_at, url for each. Useful when you want to find a video ID without opening the browser. ### get — fetch full metadata for a single video ```bash python3 ~/.claude/skills/yt-upload/yt.py get VIDEO_ID ``` Returns title, description, tags, category, privacy_status, publish_at, duration, stats (views/likes/comments), URL. ## Common workflows ### Schedule a longform video (replaces Blotato YouTube uploads) 1. Pull the title from `~/content/youtube//titles.md` (recommended title). 2. Strip the H1 and frontmatter from `~/content/youtube//description.md` and write to a temp file. 3. Pull tags from the `Tags:` line at the bottom of `description.md` and write to a temp file. 4. Compress thumbnail if > 2 MB: ```bash sips -s format jpeg -s formatOptions 80 input.png --out output.jpg ``` 5. Upload with `--publish-at` set to your chosen time in his timezone (Eastern). 6. Save the video_id to `~/content/youtube//youtube_video_id.txt` so future updates can find it. ### Swap a thumbnail because CTR is weak 1. Find the video_id (`yt.py list --max 10` if needed). 2. Compress backup thumbnail to JPG < 2 MB. 3. Run `yt.py thumbnail VIDEO_ID --image NEW.jpg`. 4. Append a note to `~/content/youtube//fallbacks.md` under "Thumbnail change log" with date + reason. ### Edit a title or description after publish 1. Edit `~/content/youtube//description.md` or `titles.md` first (single source of truth). 2. Run `yt.py update VIDEO_ID --title "..."` or `--description-file path`. 3. If swapping the title to an A/B backup, also note it in `fallbacks.md`. ### Post a comment ```bash python3 ~/.claude/skills/yt-upload/yt.py comment VIDEO_ID --text "$(cat comment.txt)" ``` ## Rules - **Always confirm before scheduling/uploading**, even if approved earlier in the session (matches `feedback_confirm_before_scheduling.md`). - **Description bodies must not contain em dashes** — replace with hyphens before sending (matches `feedback_no_em_dashes.md`). - **Strip the H1 and `---` frontmatter** from `description.md` before passing as `--description-file`. - **Thumbnail max 2 MB** — compress with sips before uploading. - **Tags max 500 chars total** — script auto-truncates but warn the user if any get dropped. - **Default category is 28 (Science & Technology)** for tech tutorials. Use 27 (Education) for course-style content. - **Save the video_id** after upload so future edits can find it. Recommend `~/content/youtube//youtube_video_id.txt`. - **Eastern Time** is your default timezone for `--publish-at` unless he says otherwise. ## Quotas YouTube Data API v3 has a daily quota of 10,000 units (default project quota). Cost per call: - `videos.insert` (upload): 1600 units — burns ~6 uploads/day max - `videos.update`: 50 units - `thumbnails.set`: 50 units - `commentThreads.insert`: 50 units - `videos.list` / `playlistItems.list`: 1 unit - `search.list`: 100 units If quota errors hit, tell the user to wait 24 hours or request a quota bump in Google Cloud Console. ## Troubleshooting **`invalid_grant: Token has been expired or revoked`** Run `python3 ~/.claude/skills/yt-upload/yt.py auth --reauth` to redo the browser flow. **`forbidden: The user is not enabled for using the YouTube Partner Program`** Some scopes (like setting custom thumbnails) require the YouTube channel to have verified the phone number on the channel. the channel owner set this up — should not hit this in practice. **`videoNotFound`** The video_id is wrong, or it was deleted, or the channel that owns it isn't the authorized channel. Run `yt.py list` to verify which channel is authorized. **`uploadLimitExceeded`** You hit the daily upload limit (15 uploads/day for unverified channels, 100/day for verified). your channel is verified — should not hit.
