🖼️ AI YouTube Thumbnail Text Generator — Create CTR-Boosting Thumbnail Text That Gets Clicks

Input your video topic. Get 15 thumbnail text variations optimized for maximum click-through rate — with size recommendations, color schemes, and font suggestions. Stop losing viewers to boring thumbnails.

💥 Why Every YouTuber, Creator & Brand Needs This Skill

Usage Guidance
This skill is instruction-only and largely plausible for generating thumbnail text, but it references scraping competitor thumbnails with Apify and using InVideo without declaring API keys, installs, or how network access is used. Before installing or using it: (1) confirm whether the skill (or your agent) will actually call Apify/InVideo and whether you'll need to provide API credentials — never share keys unless you trust the destination and understand scope/permissions; (2) be aware that scraping competitor thumbnails may violate site Terms of Service or copyright; (3) treat the CTR and revenue 'predictions' as heuristic estimates unless the skill documents a validated model or dataset; (4) if you need automated scraping/design, prefer a skill that explicitly lists required credentials, network endpoints, and data-retention behavior. If the author can clarify how Apify/InVideo are used (and whether credentials are required), that information would change this assessment toward benign.
Capability Analysis
Type: OpenClaw Skill Name: ai-youtube-thumbnail-text-generator Version: 1.0.0 The skill bundle consists of metadata and a markdown description for a YouTube thumbnail text generator. It contains no executable code and the instructions in SKILL.md are strictly aligned with its stated purpose, featuring marketing content and affiliate links for Apify and InVideo AI rather than any malicious logic or prompt injection attempts.
Capability Assessment
ℹ Purpose & Capability
The goal (15 thumbnail text options, CTR scores, color/font/size guidance) is coherent with a text-generation/inference-only skill. However, the SKILL.md repeatedly references Apify scrapers and InVideo for analysis/design, which implies external tooling or API use that the manifest does not request or justify (no API keys, no binaries, no install). This is an inconsistency but could be an omission rather than malicious intent.
⚠ Instruction Scope
The workflow explicitly says to 'Scrape top 20 viral thumbnails in your niche using Apify' and to 'analyze' them. Those are network and data-collection actions (downloading competitor thumbnails, analyzing images) that are not further specified. The instructions give broad directives to scrape and analyze external content but do not specify how the agent is expected to authenticate to Apify or where scraped data is stored, which creates operational ambiguity and potential privacy/TOS risks.
✓ Install Mechanism
No install spec and no code files — lowest-risk delivery mechanism. Nothing would be written to disk by the skill itself. That said, the instructions reference third-party services (Apify, InVideo) but provide no installation or integration details.
ℹ Credentials
The manifest requests no environment variables or credentials, which is appropriate for a purely instruction-based text generator. However, the SKILL.md names external services that normally require API credentials (Apify, InVideo). The absence of declared credential requirements is an inconsistency: if the skill needs those services to function, it should declare what access it requires.
✓ Persistence & Privilege
The skill is not forced-always, does not request elevated or persistent system presence, and is user-invocable — standard and proportionate for this type of skill.
