This skill defines exactly what to produce for a Reddit ad. It is platform-spec only: the slots Reddit exposes per format, the asset specs, the CTA enum, AND — critically — the native-voice and subreddit-fit rules that decide whether the ad performs or gets reported/downvoted.
Reddit is the platform where polished ad creative DIES. The audience is hostile to obvious advertising. The ads that work look like organic Reddit posts: first-person voice, real screenshots, plain headlines, honest reasoning, founder/maker accounts, comments enabled and actively answered.

Pick the CTA matching the actual landing-page action. Mismatched CTA is a top reason for low Reddit CTR.

Post-IPO (March 2024) Reddit tightened enforcement.
Prohibited entirely: illegal drugs, weapons, ammunition, exploitative content, fraud / get-rich-quick, deceptive claims, deepfakes / manipulated media of real people, hate speech, political ads targeting elections (most regions; case-by-case allowlist).
Restricted (allowed with gating, certification, or geo-limits):
IP / Trademark: enforced via takedown; do not use competitors' marks, do not impersonate other brands or Reddit itself.
