AB postnitro

Create on-brand social media carousels, single-image posts, and short videos, and schedule them to LinkedIn, Instagram, TikTok, and Threads from a single command. Turn a topic, article, or X thread into a finished multi-slide post, image, or video (with an optional audio track) — or import your own content — then publish or draft it automatically. Fully scriptable (JSON in, JSON out), so an AI agent can run the entire create-to-schedule workflow. Use this skill whenever the user wants to create a carousel, image post, video, reel, slide post, or multi-slide content, repurpose an article, blog post, or X thread into slides or a video, or automate and schedule social media posts. Use it to create and schedule content through PostNitro, not as a general social-media strategy advisor. Requires a PostNitro API key.

How to improve

  1. The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
For the model run — optional
  • 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.

Against the Agent Skills spec

  • warning body-long SKILL.md body ≈ 5092 tokens (recommended < 5000); move details to references/
  • note frontmatter-key unknown frontmatter key "homepage"

Process rating: all ten parameters 66/100

  • 0Inputs and preconditions. Does not say what the process needs to start
  • 0Progress reporting. Says nothing while it works
  • 30Running it twice. 21 mutating operations with no state check
  • 60Tools and files. Uses tools (bash) that frontmatter does not declare
  • 60Result and completion. Output format stated, no completion criterion
  • 70When it triggers. States when to use, but not when not to
  • 70Execution cost. Instruction body is 5092 tokens
  • 100Steps. 55 steps
  • 100Failures and branches. 2 branches, has a failure section
  • 100Consistency. Name and required fields are in place
  • medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
  • low The response is described with custom markup (4 tags): a typed call is more reliable

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.
