+
+# Address PR Review Comments
+
+Read the active pull request, identify unresolved review comments and feedback, implement the requested changes, and resolve the threads.
+
+## When to Use
+
+- A reviewer has left comments or change requests on the active PR
+- You need to systematically work through all open review threads
+- You want to respond to or implement reviewer feedback
+
+## Procedure
+
+### 1. Read the Active PR
+
+Call the `github-pull-request_activePullRequest` tool.
+
+**Refresh logic**: Check whether a refresh is needed before reading:
+- Call the tool once *without* `refresh` to get the cached state
+- Inspect the `lastUpdatedAt` field in the result
+- If the timestamp is **less than 3 minutes ago**, the PR is actively changing - call the tool again with `refresh: true` to ensure you have the latest comments and state
+- If the timestamp is older than 3 minutes, proceed with the cached data
+
+### 2. Identify Unresolved Comments
+
+From the tool result, collect all feedback that needs action:
+
+- **`comments`** array: inline review thread comments where `commentState` is `"unresolved"`
+- **`timelineComments`** array: general PR comments and reviews where `commentType` is `"CHANGES_REQUESTED"` or `"COMMENTED"`
+
+Group related comments by file (`file` field) to handle them efficiently.
+
+### 3. Plan Changes
+
+Before modifying any files:
+1. Read each unresolved comment carefully
+2. Identify the file and location each comment refers to
+3. Determine the minimal correct fix for each, if a fix is needed (not all comments are worthy of a change)
+4. Note dependencies between comments (e.g., a rename that affects multiple files)
+
+### 4. Implement Changes
+
+Work through the grouped comments file by file:
+- Read the relevant file section before editing
+- Apply the requested change
+- Do not refactor or modify code outside the scope of each comment
+- If a comment is unclear or contradictory, note it for a follow-up reply rather than guessing
+
+### 5. Verify
+
+After all changes are made:
+- Review that each originally unresolved comment has a corresponding code change or a note about why no code change was needed.
+- Ensure no unrelated code was modified
+
+### 6. Summarize
+
+Provide a concise summary of:
+- Which comments were addressed and what changes were made
+- Any comments that were intentionally skipped (with reasoning)
+- Any follow-up questions for the reviewer
