Short Video Caption & Subtitle Design Guide

Guides caption styling, placement, timing, and accessibility for short video subtitles to enhance readability, engagement, and platform fit.

Security Scan

This is a document-only caption/style guidance skill with no code, no installs, no network calls, and no credential requirements — its declared purpose matches its implementation.

Purpose & Capability

Name, description, and files are purely descriptive guidance about caption styling; there are no extraneous permissions, binaries, or credentials requested that would be unexpected for this purpose.

Instruction Scope

SKILL.md contains only workflow, inputs, outputs, examples, and disclaimers about scope; it does not instruct the agent to read local files, access environment variables, call external endpoints, or perform actions outside caption design guidance.

Install Mechanism

There is no install spec and no code to install or execute. Instruction-only skills have the lowest install risk and this skill follows that pattern.

Credentials

No environment variables, credentials, or config paths are required; requested access is proportional to a documentation-only skill.

Persistence & Privilege

Skill is not marked 'always' and does not request persistent or elevated privileges or modification of other skills. Default autonomous invocation is allowed but not accompanied by other risks.

Assessment

This skill is low-risk: it only provides written guidance and includes no executable code, network endpoints, or credential requests. You can install it safely for reference, but remember it will not transcribe, render, or verify captions — always validate generated style decisions against real video previews and accessibility standards (e.g., WCAG) and do not rely on it for legal or compliance guarantees. Also be aware that, like other skills, the agent may invoke it autonomously by default; since it has no external access or secrets, that behavior does not add meaningful risk here.

Covers caption strategy — styling, placement, timing, accessibility, and engagement — for short video subtitles and on-screen text.
