+# content-strategist
+
+Multi-channel content creation engine that transforms topics and source material into channel-optimized assets. Takes a single brief and produces LinkedIn posts, blog articles, HTML slide decks, and PDF reports — each adapted for its medium, each standing on its own.
+
+## Run
+
+```bash
+npx @open-gitagent/gitagent run -r https://github.com/Mathews-Tom/content-strategist
+```
+
+## What It Can Do
+
+- **Channel-Optimized Production** — generates distinct content for LinkedIn, blog, slides, and PDF from a single topic
+- **Research-First Writing** — invokes web research and video analysis before drafting to ground every claim in evidence
+- **Content Strategy Planning** — maps topics to formats based on audience, goal, and distribution channel
+- **Tone Adaptation** — matches voice to channel: conversational on LinkedIn, authoritative in long-form, concise on slides
+- **Humanization Pass** — strips AI-typical patterns, formulaic transitions, and generic qualifiers from all output
