+description: Resolve all PR comments using parallel processing
+argument-hint: "[optional: PR number or current PR]"
+---
+
+Resolve all PR comments using parallel processing.
+
+Claude Code automatically detects and understands your git context:
+
+- Current branch detection
+- Associated PR context
+- All PR comments and review threads
+- Can work with any PR by specifying the PR number, or ask it.
+
+## Workflow
+
+### 1. Analyze
+
+Get all unresolved comments for PR
+
+```bash
+gh pr status
+bin/get-pr-comments PR_NUMBER
+```
+
+### 2. Plan
+
+Create a TodoWrite list of all unresolved items grouped by type.
+
+### 3. Implement (PARALLEL)
+
+Spawn a pr-comment-resolver agent for each unresolved item in parallel.
+
+So if there are 3 comments, it will spawn 3 pr-comment-resolver agents in parallel. liek this
+
+1. Task pr-comment-resolver(comment1)
+2. Task pr-comment-resolver(comment2)
+3. Task pr-comment-resolver(comment3)
+
+Always run all in parallel subagents/Tasks for each Todo item.
+
+### 4. Commit & Resolve
+
+- Commit changes
+- Run bin/resolve-pr-thread THREAD_ID_1
+- Push to remote
+
+Last, check bin/get-pr-comments PR_NUMBER again to see if all comments are resolved. They should be, if not, repeat the process from 1.
