Writer Skill

Iterative writing loop that combines Gemini 3 Pro's writing capabilities with Claude's review.

Flow

1. User provides topic/context
2. Gemini 3 Pro writes draft
3. Claude Agent SDK reviews autonomously
4. If not approved, Gemini rewrites with feedback
5. Loop until approved (max 15 iterations)
6. DeepL improves grammar/style (if API key set)
7. Claude merges DeepL suggestions (preserves code, markdown, technical terms)

Usage

shelve run --project Personal -- npx tsx ~/.claude/skills/writer/scripts/write-loop.ts "Write a blog post about Vue 3 composition API"

With context file:

shelve run --project Personal -- npx tsx ~/.claude/skills/writer/scripts/write-loop.ts "Write docs for this component" --context ./Component.vue
