authority-ad — Claude Code skill: what it does, how to install
This skill plans and audits expert-led ads built around evidence. Use it for ad concepts, shot scripts, review passes, and production handoff.
npx skills add PostPlusAI/postplus-skills --skill authority-ad -a claude-codeWhat authority-ad does
The skill has separate create and review modes. For a new ad, it builds an Authority Grammar Plan covering the audience pressure, speaker role, authority basis, causal argument, proof stack, product entry, and closing state. It then produces a shot table with visual direction, framing, camera movement, sound, text, and the job of each shot.
For an existing ad, the workflow starts with $media-analysis. The skill reports the factual structure, speaker role, product timing, timecoded strengths and gaps, proof mapping, claim risks, and concrete amendments. It does not rewrite the ad or move it into production unless asked. Review therefore depends on observable shot and audio evidence.
After approval, the locked script can go to $image-batch-runner first when continuity assets are needed, followed by $video-batch-runner. If the identity, offer, scenes, proof assets, audio, and references are already stable, the handoff can go straight to $video-batch-runner. The skill also blocks invented credentials, testimonials, study results, guarantees, and product capabilities.
What it helps with
- plan an expert-led ad around a clear mechanism
- map spoken claims to visible proof
- audit an existing video with timecoded findings
- flag unsupported claims and continuity issues
- route an approved shot script into production
Example prompts for the agent
- Plan an expert-led ad for this product using only approved facts and available proof.
- Review this ad with the authority-ad framework and return a timecoded audit.
- Once I approve the direction, hand the locked script to production.
