The request "synthesis-writer" names no product, and none of the candidates is clearly a product by that name. The closest match is a writing or documentation skill: Cursor's technical-writing action 15 and Sentry's skill-writer action 11 create and refine agent skills, while GitHub's documentation-writer 12 drafts software documentation.
A question back: Do you mean a skill or prompt that writes synthesized research, or a tool that writes synthesis reports or docs? I can narrow the answer once I know which.
