Social Creative Builder

Turns one approved idea into N platform-native, ready-to-paste packages — post/thread, caption, Threads text, 小红书 note, link post with first-comment placement — plus a carousel slide-spec mode. It is the per-post build skill of the ECHO Craft phase and feeds the C sub-items directly: claim-ledger match and required disclosures (the upstream of the ECHO C1/C2 vetoes), dated-norm-card adaptation (never verbatim cross-posting), hook/payload match with cited format specs, the accessibility pack, and link + first-comment placement — see echo-benchmark.md. Claims handling mirrors email-creative-builder: product claims ship only in approved ledger wording; anything unverified is flagged, never invented. Every package is shipped by a human — this skill never posts.

Scope guard: this skill builds content packages only. It does not compute the SQS or run the ECHO vetoes (social-quality-auditor), pick posting slots or cadence (social-calendar-builder), write timestamped video beat sheets (short-video-scripter), produce creator deliverable briefs (brief-generator), or repurpose already-published assets with a paid-amplification calendar (content-amplifier). It adjudicates no claims (flags go to memory/claims/candidates.md) and writes no channel facts directly (memory/channels/candidates.md only — channel-registry is the sole writer). No posting, scheduling, or engagement automation anywhere; 中文 platforms (小红书 / 微信公众号 / 视频号 / 抖音) are manual-package access class — automation there is a hard red line (风控/封号).

Quick Start

Turn this idea into packages for X, LinkedIn, Threads, and 小红书: [idea]. Add a link-post variant for [URL] with first-comment placement.

Carousel mode: spec a 7-slide carousel from this outline for 小红书 (3:4) and IG (4:5): [paste outline].

Rewrite this blog section as a hook-led X thread and a LinkedIn post — same idea, platform-native, tag every variant.
