What problem does it solve? Reviewing markdown drafts (specs, plans, brainstorms) with a human in the loop is awkward over chat alone. This Skill uploads local markdown files to Proof, the collaborative editor at proofeditor.ai, so a human can annotate in a web UI while the agent reads comments, replies in-thread, applies tracked edits, and syncs the final document back to disk. ## Core Features & Use Cases - Share and edit markdown via Web API: Create shareable Proof documents with a token URL, read state, add comments, and apply tracked suggestions or atomic block-level edits through the /ops and /edit/v2 endpoints. - Human-in-the-loop review loops: Run a full HITL cycle — upload a local file, ingest human feedback as in-thread replies and accepted suggestions, report open threads in the terminal, and atomically sync the reviewed doc back to the local file. - Local bridge mode: Drive the macOS Proof app over localhost:9847 for presence, marks, and rewrites when the desktop app is running. - Use Case: After drafting a plan with ce-plan, hand the markdown file off for review — the user highlights text and leaves comments in Proof, the agent applies fixes with an auditable suggestion trail, and the reviewed document is written back to disk. ## Quick Start Share the markdown file I just created to Proof so we can iterate on it together, then sync the reviewed version back to my local file.
