backnotprop-plannotator is a Claude Code plugin that lets you visually annotate agent plans and code diffs, share reviews, and send one-click feedback back to the agent.
About
backnotprop-plannotator is a Claude Code plugin that turns opaque agent plans and patches into something you can actually judge: an interactive surface to annotate plans, mark up diffs, and share a review link with your team. developers use it when a session has proposed a large plan or sprawling diff and you need human judgment before burning tokens on execution—especially when you want comments anchored to specific lines or sections rather than a vague chat reply. It integrates via hooks so review can sit in your normal agent loop instead of copying patches into another tool. After review, you can send consolidated feedback to the agent in one action, which shortens the iterate-and-fix cycle compared to re-pasting screenshots or prose instructions. It is not a planner itself; it is the visual review and collaboration layer on top of whatever agent already produced the plan or diff.
- Visual annotation for agent plans and code diffs with hooks that integrate into Claude Code workflows
- One-click feedback from annotations back to the coding agent
- Shareable review sessions for solo builders looping in collaborators or stakeholders
- Interactive refinement loop to refine plans before implementation runs
- Single-plugin bundle (plannotator) focused on collaboration around agent plans

What it does
Review Claude Code agent implementation plans and diffs in a visual UI, then push structured feedback back into the session with one click.
Who is it for?
Best when you're running Claude Code on large plans or diffs and want structured human review before merge or the next agent turn.
Skip if: Skip if you only need inline IDE diff review with no agent handoff, or teams that do not use Claude Code hooks.
What you get
You get a visual review workflow where annotated feedback returns to the agent quickly and teammates can align on the same plan or diff.
- Annotated plan or diff review with anchored comments
- Shareable review artifact for collaborators
- Structured feedback payload sent back to the coding agent
