Description
Generate professional social media carousel posts using the PostNitro.ai Embed API. Supports AI-powered content generation and manual content import for Link...
Usage Guidance
This skill will send whatever you ask it to the PostNitro embed API (embed-api.postnitro.ai) using the API key you provide. Only grant an API key you trust PostNitro with, avoid sending sensitive/personal data through the skill, and prefer a scoped or revocable key if PostNitro supports it. Rotate or revoke the key if you stop using the skill, and check PostNitro's privacy/security docs if you need to know how uploaded content and generated images are stored or shared.
Capability Analysis
Type: OpenClaw Skill
Name: postnitro-carousel
Version: 2.0.0
The skill bundle is a legitimate integration for the PostNitro.ai API, designed to generate social media carousels. It uses standard environment variables for authentication and provides clear instructions for the AI agent to interact with the service via curl. No evidence of data exfiltration, malicious execution, or harmful prompt injection was found; all behaviors and endpoints (embed-api.postnitro.ai) are consistent with the stated purpose.
Capability Assessment
Purpose & Capability
Name/description describe creating social media carousels via PostNitro; required env vars (API key, template/brand/preset IDs) and the documented API endpoints align directly with that purpose. The primary credential (POSTNITRO_API_KEY) is appropriate and used as the auth header in all examples.
Instruction Scope
SKILL.md contains explicit curl examples: POST to initiate generate/import, GET to poll status and GET to retrieve output. The instructions only reference the PostNitro embed API, example public image URLs, and the declared environment variables. There are no steps that ask the agent to read unrelated files, secrets, or system state.
Install Mechanism
No install spec and no code files — instruction-only skill — so nothing is written to disk or fetched during install. This minimizes installation risk.
Credentials
Requires an API key plus three IDs used to select template/brand/preset. These are reasonable and proportionate for a hosted design-generation API. The skill does not request unrelated credentials or filesystem config paths.
Persistence & Privilege
always:false and no install actions mean the skill does not request elevated or permanent presence. It does not modify other skills or system configuration.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install postnitro-carousel - After installation, invoke the skill by name or use
/postnitro-carousel - Provide required inputs per the skill's parameter spec and get structured output
