Plannotator란 무엇인가요

Plannotator is an open-source tool designed to bring human-in-the-loop control to AI coding agents. It acts as an intermediary layer that intercepts agent-generated plans and code changes, providing a dedicated interface for review, annotation, and feedback. Instead of relying on terminal-based outputs, users can annotate plans, mark deletions, and suggest modifications directly. These annotations are converted into structured feedback that the agent can interpret, ensuring the final output aligns with developer intent. With native support for tools like Claude Code, Copilot, and Gemini, Plannotator bridges the gap between agent autonomy and developer oversight, allowing for PR-style diff reviews and iterative refinement before code is ever committed.

Plannotator 사용 방법

Install Plannotator via the provided shell script command.,Continue using your preferred AI coding agent as you normally would.,When the agent proposes a plan, Plannotator automatically intercepts the step.,Review the plan in the dedicated workspace, adding inline comments or marking deletions.,Approve or deny the plan; your structured feedback is sent directly back to the agent.,Run /plannotator-review to inspect agent-written code changes in a PR-style diff viewer before committing.
