 # GitHub PR Review
 
 ## Overview
 
-Fetch unresolved review threads from the current PR, consolidate them into actionable items, and address selected items — each as a separate commit.
+Fetch unresolved review threads from the current PR, consolidate them into actionable items, address selected items (each as a separate commit), and resolve threads on GitHub with reactions or explanatory comments.
 
 ## Prerequisites
 
 - `gh` CLI authenticated and in a repo with an open PR on the current branch
 - The `git-commit` skill available for committing changes
 
+## Scripts
+
+- `gh_review.sh` — Fetches unresolved threads, prints human-readable summary, and appends a compact thread mapping block at the end with item numbers, thread IDs, and comment IDs for downstream resolution.
+- `gh_resolve_thread.sh` — Resolves a GitHub review thread, optionally adding reactions or a comment first.
+
+### `gh_resolve_thread.sh` Usage
+
+```bash
+# Thumbs-up on comments, then resolve
+bash gh_resolve_thread.sh thumbsup <thread-id> [comment-id1 comment-id2 ...]
+
+# Post a reply explaining why, then resolve
+bash gh_resolve_thread.sh comment "reason" <thread-id>
+```

 If the script fails (no PR, not authenticated, etc.), report the error and stop.

+Capture these IDs from the script output — they are needed in step 5.

 ### 2. Consolidate into Actionable Items
 
 Parse the output and group into actionable items. Combine threads that ask for the same change (e.g. multiple reviewers commenting on the same function about the same concern). Keep items separate when they require distinct code changes.

-After all selected items are addressed, print a brief summary of what was done.
+After all code changes are committed, resolve the corresponding threads on GitHub using the thread IDs and comment IDs from the script output in step 1:
+
+1. For **addressed items**: run `bash gh_resolve_thread.sh thumbsup <thread-id> <comment-ids...>` — adds 👍 to each comment, then resolves the thread.
+2. For **skipped items**: ask the user for a brief reason, then run `bash gh_resolve_thread.sh comment "<reason>" <thread-id>` — posts an explanation, then resolves.
+
+Only resolve threads for items the user explicitly selected (addressed or skipped). Leave untouched items unresolved.

+After all selected items are addressed and threads resolved, print a brief summary of what was done (code changes + thread resolutions).
