Usage Guidance
This skill appears to do what it says (cloud-based A/B captioning) and only needs one API token, but check these before installing: 1) No homepage or publisher site is provided — verify the vendor (nemovideo / mega-api-prod.nemovideo.ai) and confirm you trust that domain. 2) The skill will upload your videos to an external cloud service (and can create an anonymous NEMO_TOKEN if you don't supply one) — do not use it with sensitive or private media unless you accept that. 3) There's a minor metadata inconsistency: frontmatter references ~/.config/nemovideo/ while the registry entry did not; ask the author to clarify whether any files will be created on disk. 4) If you supply your own NEMO_TOKEN, ensure it was issued by the official service and has appropriate scope; otherwise allow the anonymous token flow but be aware of the 7-day limited token and free-credit behavior. 5) Prefer installing as user-invocable only (do not set always:true) and request a homepage/privacy policy from the publisher before use.
Capability Analysis
Type: OpenClaw Skill
Name: social-caption-ab
Version: 1.0.0
The skill provides a legitimate interface for a cloud-based video captioning and editing service hosted at nemovideo.ai. It manages authentication via an anonymous token flow, handles video uploads to specific API endpoints, and polls for rendered results, all of which are consistent with its stated purpose of A/B testing social media captions. No evidence of data exfiltration, malicious code execution, or harmful prompt injection was found in SKILL.md or _meta.json.
Capability Assessment
Purpose & Capability
Name/description match the runtime behavior: the SKILL.md describes uploading videos and calling a nemo video backend to create captioned A/B renderings. Requesting a single NEMO_TOKEN credential is consistent with a cloud API-backed service. Minor inconsistency: the registry 'Requirements' said no config paths, but the SKILL.md frontmatter metadata includes a config path (~/.config/nemovideo/) — this is unexplained but not critical to the stated purpose.
Instruction Scope
The instructions instruct the agent to look for NEMO_TOKEN and, if absent, obtain an anonymous token by POSTing to https://mega-api-prod.nemovideo.ai and then create sessions, upload video files, start SSE render streams, poll for render completion, and return download URLs. All of that is within scope for a cloud-rendering captioning skill. Note: the skill will upload user videos to an external service and will auto-generate/retain session tokens; it also asks the agent to auto-detect install path for a header value (reading agent environment), which is minor scope creep. There are no instructions to read unrelated system secrets or to exfiltrate other data.
Install Mechanism
This is an instruction-only skill with no install spec and no code files — lowest risk for arbitrary code installation. There are no download/extract instructions or third-party package installs in the SKILL.md.
Credentials
The skill only requires a single credential (NEMO_TOKEN) which is appropriate for a single cloud API. It also contains workflows to obtain an anonymous token automatically if none is provided. The frontmatter references a config path (~/.config/nemovideo/) that is not listed in the registry 'Requirements' — inconsistent but not necessarily malicious. Consider that user video files and any metadata you send will be handled by the external service; that is a privacy risk if your content is sensitive.
Persistence & Privilege
The skill is not always: true, is user-invocable, and does not request persistent system-wide privileges. It instructs keeping session_id for operations (expected ephemeral behavior) and does not request modifying other skills or system-wide config.
