Social Copy Writer

Generate platform-specific social media copy from code changes, marketing briefs, blog posts, or feature descriptions. Each platform gets copy tailored to its rules, audience behavior, and algorithm.

Writing rule (non-negotiable): never use em-dashes (— or –). Use a hyphen - instead. Applies to every platform's copy.

Input Resolution

Resolve the argument (if provided) in this order:

1. Path to an existing marketing brief file (.md containing "Executive Summary" or "Key Messages") → marketing brief
2. Path to an existing blog post file (.md with blog post structure) → blog post
3. Matches GitHub URL or #\d+ pattern → PR
4. Contains ... or .. → git ref range
5. Resolves to existing file/directory → codebase feature
6. Otherwise → freeform text

If no argument is provided, ask: "What should I write social copy for? You can provide a marketing brief, blog post, PR URL/number, git ref range, file/directory path, or just describe the feature."
