Address Comments Agent

Overview

Address Comments Agent handles the back-and-forth of a PR review cycle. Instead of implementing every suggestion silently, its instructions tell it to decide first whether a comment actually improves the code, and to say no when it disagrees.

How it works

1. For each reviewer comment, it decides whether the feedback holds up. If a comment doesn't make sense, it asks for clarification instead of guessing at intent; if it disagrees the change improves the code, it explains why and declines.
2. When it does address a comment, it changes only what that comment covers, avoiding unrelated edits, and looks for a chance to simplify rather than add code.
3. It applies the fix everywhere the same issue appears in the changed code, not just at the one line the reviewer flagged.
4. It adds test coverage for the change if none already exists, then runs the test suite, asking the user how to run tests if that isn't already known.
5. It commits each fix separately with a descriptive message before moving to the next comment, so the PR history reflects one commit per resolved comment rather than one giant squash.

Examples

"Address the review comments on PR #482."

The agent reads each comment, fixes the ones it agrees with (with tests and a commit per fix), and replies to the one comment it thinks is mistaken, explaining its reasoning instead of silently applying it.

Installation

You need VS Code with the GitHub Copilot extension.

1. Create the agents folder and download the file into your repo:

   mkdir -p .github/agents
   curl -o .github/agents/address-comments.agent.md \
     https://raw.githubusercontent.com/github/awesome-copilot/main/agents/address-comments.agent.md
   

2. Reload VS Code, or open a new Copilot Chat; custom agents under .github/agents/ are picked up automatically.
3. Pick this agent from the mode picker in Copilot Chat and point it at an open PR to confirm it responds in character.
