AB postnitro-carousel
Generate professional social media carousel posts using the PostNitro.ai Embed API. Supports AI-powered content generation and manual content import for LinkedIn, Instagram, TikTok, and X (Twitter) carousels. Use this skill whenever the user wants to create a carousel, social media post, slide deck for social media, multi-slide content, or mentions PostNitro. Also trigger when the user asks to turn text, articles, blog posts, or topics into carousel posts, or wants to automate social media content creation. Outputs PNG images or PDF files. Requires a PostNitro API key.
As a process B 77/100 · Nearly there — weak spots: inputs and preconditions, progress reporting
How to improve
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
