YouTube — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the

youtube-pp-cli

binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

Install via the Printing Press installer:

bash

npx -y @mvanhorn/printing-press-library install youtube --cli-only

Verify:
```
youtube-pp-cli --version
```
Ensure
```
$GOPATH/bin
```
(or
```
$HOME/go/bin
```
) is on
```
$PATH
```
.

If the

npx

install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.3 or newer):

bash

go install github.com/mvanhorn/printing-press-library/library/media-and-entertainment/youtube/cmd/youtube-pp-cli@latest

--version

reports "command not found" after install, the install step did not put the binary on

$PATH

. Do not proceed with skill commands until verification succeeds.

When to Use This CLI

Use this CLI when you have search terms (from photo tags, image labels, or notes) and want relevant YouTube videos back — with transcripts to verify relevance and embed snippets to drop into a blog draft. It's read-only and local; not a webapp backend, not a write tool.

When Not to Use This CLI

Do not activate this CLI for requests that require creating, updating, deleting, publishing, commenting, upvoting, inviting, ordering, sending messages, booking, purchasing, or changing remote state. This printed CLI exposes read-only commands for inspection, export, sync, and analysis.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Blog-post composition

youtube search-bulk
— Take a list of search terms from stdin or args, return top-N YouTube videos per term in one JSON document with titles, channels, embed URLs, and thumbnails.
When you have N search terms from an upstream pipeline (image labels, photo tags, scraped keywords), reach for this instead of looping single searches.
bash
```
youtube-pp-cli youtube search-bulk "sourdough scoring" "latte art" --top 3
```
youtube videos-transcript
— Fetch the spoken-content transcript of a YouTube video using the timedtext endpoint. Works for auto-generated and manual captions on any public video. Caches into the local store.
Read the transcript before deciding whether a candidate video actually fits the topic of the blog post or photo.
bash
```
youtube-pp-cli youtube videos-transcript dQw4w9WgXcQ --lang en --json
```
youtube videos-embed
— Print embed HTML, iframe, or markdown-style embed for a video ID. Direct copy-paste into a blog draft.
Once you've picked a video for the blog, get the embed snippet without remembering the exact iframe URL pattern.
bash
```
youtube-pp-cli youtube videos-embed dQw4w9WgXcQ --format markdown
```

Reachability mitigation

youtube videos-related
— Find videos related to a target video using topicDetails + same-channel + tag overlap from the local store. Best-effort replacement for the deprecated relatedToVideoId parameter.
When one candidate video is on-topic but you want more like it, this is the working stand-in for the deprecated parameter.
bash
```
youtube-pp-cli youtube videos-related dQw4w9WgXcQ --limit 10 --json
```

Audience signal

youtube videos-comments
— Fetch top comments on a video, ranked locally by likeCount. Pulls up to 5 pages from commentThreads.list and sorts so most-liked floats regardless of API order.
Use to gauge whether a video is actually well-received before embedding, or to surface viewer-supplied context the description doesn't mention.
bash
```
youtube-pp-cli youtube videos-comments dQw4w9WgXcQ --top 10
```

Channel discovery

youtube channel-uploads
— List a channel's most recent uploads in one call. Resolves @handle or channelId, walks the auto-generated uploads playlist, returns video IDs + titles + publish times.
Replaces the manual two-step lookup. Pairs naturally with --for-handle workflows.
bash
```
youtube-pp-cli youtube channel-uploads @veritasium --top 10
```

Command Reference

youtube — Manage youtube

```
youtube-pp-cli youtube channels-list
```
— Retrieves a list of resources, possibly filtered. Now supports
```
--for-handle @handle
```
for modern channel resolution.
```

```
— Retrieves a list of resources, possibly filtered.

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

bash

youtube-pp-cli which "<capability in your own words>"

which

resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code

means at least one match; exit code

means no confident match — fall back to

--help

or use a narrower query.

Recipes

Sample use case: justinwfu/pictovideo puts the recipes below into a real photo-keywords → candidate-video → embedded blog draft pipeline. Look there if you want to see the commands wired end-to-end before composing your own flow.

Photo keywords to candidate videos

bash

cat photo-keywords.txt | youtube-pp-cli youtube search-bulk --stdin --top 5 --json --select "results[].videoId,results[].title,results[].channelTitle,results[].embedUrl"

Reads keywords (one per line), searches each, returns webapp-ready embed-URL JSON. Use --select with dotted paths to keep the output tight.

Verify a candidate via transcript

bash

youtube-pp-cli youtube videos-transcript dQw4w9WgXcQ --lang en --json --select "text" | head -c 2000

Pull the first 2KB of the transcript to confirm the video is actually about the topic before adding it to the blog.

Get a markdown embed for the draft

bash

youtube-pp-cli youtube videos-embed dQw4w9WgXcQ --format markdown

Drops a ready-to-paste markdown video reference into your editor buffer.

Find more candidates like a picked one

bash

youtube-pp-cli youtube videos-related dQw4w9WgXcQ --limit 5 --json --select "results[].videoId,results[].title"

Heuristic-based replacement for the deprecated relatedToVideoId. Uses topic + channel + tag overlap from synced local data.

Bulk-research pipeline

bash

cat photo-keywords.txt | youtube-pp-cli youtube search-bulk --stdin --top 3 --json | jq '.results[].videoId' | xargs -I {} youtube-pp-cli youtube videos-transcript {} --json

End-to-end: keywords in, transcripts out, ready for a quality filter before blog composition.

Auth Setup

API-key only — set

YOUTUBE_API_KEY

and you're done. Read-only public-data operations only (10,000 quota units/day default). Write operations are not configured; this CLI is for discovery and research, not channel management.

Run

youtube-pp-cli doctor

to verify setup.

Agent Mode

Add

--agent

to any command. Expands to:

--json --compact --no-input --no-color --yes

Pipeable — JSON on stdout, errors on stderr
Filterable —
```
--select
```
keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:
bash
```
youtube-pp-cli youtube channels-list --agent --select id,name,status
```
Previewable —
```
--dry-run
```
shows the request without sending
Offline-friendly — sync/search commands can use the local SQLite store when available
Non-interactive — never prompts, every input is a flag
Read-only — do not use this CLI for create, update, delete, publish, comment, upvote, invite, order, send, or other mutating requests

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

json

{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse

.results

for data and

.meta.source

to know whether it's live or local. A human-readable

N results (live)

summary is printed to stderr only when stdout is a terminal — piped/agent consumers get pure JSON on stdout.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

youtube-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
youtube-pp-cli feedback --stdin < notes.txt
youtube-pp-cli feedback list --json --limit 10

Entries are stored locally at

~/.youtube-pp-cli/feedback.jsonl

. They are never POSTed unless

YOUTUBE_FEEDBACK_ENDPOINT

is set AND either

--send

is passed or

YOUTUBE_FEEDBACK_AUTO_SEND=true

. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts

--deliver <sink>

. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

Sink	Effect
`stdout`	Default; write to stdout only
`file:<path>`	Atomically write output to `<path>` (tmp + rename)
`webhook:<url>`	POST the output body to the URL ( `application/json` or `application/x-ndjson` when `--compact` )

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

youtube-pp-cli profile save briefing --json
youtube-pp-cli --profile briefing youtube channels-list
youtube-pp-cli profile list --json
youtube-pp-cli profile show briefing
youtube-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults.

agent-context

lists all available profiles under

available_profiles

so introspecting agents discover them at runtime.

Exit Codes

Code	Meaning
0	Success
2	Usage error (wrong arguments)
3	Resource not found
4	Authentication required
5	API error (upstream issue)
7	Rate limited (wait and retry)
10	Config error
