Post Writer Skill Demo

Draft platform-tuned full social posts AND long-form Articles — LinkedIn posts + Articles, X posts + threads + Articles, Instagram caption + carousel, Threads, Facebook, YouTube (title + description) and Reddit (advise-only). Voice-aware (reads voice.md), hook-aware (composes hook-generator output). Each post scored against 2026 platform algorithm patterns, structure rules, an AI-slop blacklist, and 74 metric-bearing real exemplars + 5 enforcement scripts. GUIDANCE-ONLY: no backend and no methods — the agent's own LLM composes posts following SKILL.md, read via skill_read from the nested skills/post-writer/ layout; state persists via the upstream OPVS Coordination skills (agentdocs / agentmemory / agentboard) declared as peers. Knows the SpiderIQ publishing stack: social → vibe-publish; owned site → spiderpublish; assets → spidermedia.
