Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00043 | $0.02387 |
| Opus 5 | $0.00022 | $0.01193 |
| Sonnet 5 | $0.00009 | $0.00477 |
| Haiku 4.5 | $0.00004 | $0.00239 |
Grade A, and why
gws-youtube scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
allowed-tools: 'Bash(bash *) Bash(jq *) Bash(curl *) Bash(python3 *)' How it starts
The opening of the file, as written. The whole thing — 226 lines — stays where its author put it; the contents beside it link to each section on GitHub.
YouTube (gws)
Manage the authenticated user's YouTube playlists via bash primitives in
plugins/gws/scripts/youtube-*.sh. All operations resolve the active gws
account via account-common.sh and read client_secret.json from that
account's config dir. Tokens persist as <account-dir>/youtube_credentials.json
mode 0600 (plaintext, matching the gws plugin's bash-script convention).
Prerequisites
Confirm the user is authenticated for YouTube on the active account:
# Codex: this path resolves under Claude Code; substitute the directory containing this plugin.
PLUGIN_ROOT="${CLAUDE_PLUGIN_ROOT}"
test -f "$(jq -r '.' <(bash "$PLUGIN_ROOT/scripts/account-current.sh" --json) 2>/dev/null | jq -r '.config_dir // empty')/youtube_credentials.json" \
&& echo "youtube credentials present" \
|| echo "NOT AUTHENTICATED — run youtube-login.sh from the resolved plugin root"
If not authenticated, run youtube-login.sh first (PKCE + loopback flow,
opens a browser tab on macOS/Linux).
GCP API Enable (one-time, gnarly)
The OAuth flow succeeds before this matters, but the FIRST data-API call
will fail with HTTP 403 accessNotConfigured until YouTube Data API v3 is
enabled on the GCP project tied to the gws OAuth client. The error
message contains the project number and a direct enable URL. Extract it
and show it to the user verbatim:
https://console.developers.google.com/apis/api/youtube.googleapis.com/overview?project=<PROJECT_NUMBER>
After the user clicks "Enable" and waits ~30 seconds, retry the call. This is a one-time setup per GCP project, not per account.
Primitives
All scripts share the same flag conventions:
--account=LABEL— override the active gws account--json— machine-readable output (default: human table)--force-refresh— refresh access token before the API call (testing aid)--help— usage text
Mutating scripts (add, remove) additionally support:
--yes/-y— skip the interactive[y/N]confirmation prompt--dry-run— print the plan; make no destructive API call
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 6d ago First seen · 226 lines · 43 tokens per session scan A bb324c190dcf
gws-youtube is a skill published in the GitHub repository jtsternberg/claude-plugins (5 stars, last pushed 2d ago), licensed MIT. It adds 43 tokens to every session and 2,387 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
