Usage Guidance
This skill appears coherent: it wraps the yutu CLI and requires standard YouTube OAuth artifacts. Before installing, verify the origin and integrity of the @eat-pray-ai/yutu package (inspect the GitHub repo, npm package, and release artifacts), and ensure the OAuth client and token you provide have the minimal scopes needed. Avoid placing long-lived credentials in shared environments; prefer per-project credential files (client_secret.json / youtube.token.json) and review the token file contents before sharing. If you need higher assurance, install the tool from the repo's official releases and review its source code for unexpected network calls or telemetry.
Capability Analysis
Type: OpenClaw Skill
Name: youtube-thumbnail
Version: 0.10.7-dev
The skill bundle is a legitimate wrapper for the 'yutu' CLI tool, designed to manage YouTube video thumbnails via the YouTube Data API. It requires standard OAuth 2.0 credentials (client_secret.json and tokens) and provides clear, standard documentation for setup and usage. No evidence of malicious intent, data exfiltration, or prompt injection was found in the instructions or metadata.
Capability Assessment
Purpose & Capability
Name/description (set YouTube thumbnails) match the declared binary (yutu), required OAuth files (client_secret.json, youtube.token.json), and env vars (YUTU_CREDENTIAL, YUTU_CACHE_TOKEN). These are expected for a YouTube CLI that uses OAuth.
Instruction Scope
SKILL.md and reference files only instruct installing/using the yutu CLI and performing OAuth auth flow (local redirect, token saved to youtube.token.json). They do not ask to read unrelated files, exfiltrate data, or call unexpected external endpoints.
Install Mechanism
Install uses an npm package (@eat-pray-ai/yutu) which is reasonable for providing the yutu binary; npm packages are a moderate-risk supply chain vector compared with instruction-only skills. The included README also documents other distribution channels (brew/winget/go/releases) — not inherently problematic but verify the package and release source before installing.
Credentials
Requested env vars and config paths (OAuth client secret and cached token) are expected and proportionate for authorizing against the YouTube Data API. The primary credential (YUTU_CREDENTIAL) matches the service purpose.
Persistence & Privilege
Skill is not forced-always, does not request elevated agent-wide privileges, and is instruction-only (no code written by the skill). Autonomous invocation is enabled by default but not combined with other concerning flags.
How to Use
- Make sure OpenClaw is installed (local or Docker)
