GOAL
Execute five code simplification plans (Android, iOS, website, root scaffolding, etc.) concurrently using parallel subagents that coordinate via a messenger tool within the same git worktree.
- +0Prompt · +0Use multiple parallel subagents to work on code simplification plans 4-8 from .agents/plans/27-code-simplification/, coordinating via /messenger, checking build after each step, committing only their own files.
- +0mAgent did · +0mListed the code simplification plan files in the target directory to identify the plans to execute.
- +0mFail · +0mFirst attempt to spawn a subagent named 'android-simplifier' failed because that agent type didn't exist.
- +1mFail · +1mSecond attempt using agent name 'coder' also failed for the same reason.
- +1mAgent did · +1mListed available agent types, found 'worker' as valid, and successfully spawned parallel worker subagents for all five simplification plans.
- +14mAgent did · +14mAll 5 subagent tasks succeeded: Android release builds got R8 minification/resource shrinking, iOS had dead code removed and payload centralized, plus other plans completed with commits made per task via git log verification.
- +17mPrompt · +17mRemove .pi/messenger/feed.jsonl from git tracking, add it to .gitignore, keep the local file, then commit and push.
- +17mFail · +17mCommitting after adding the gitignore entry failed because git refused to add the now-ignored file explicitly.
- +17mAgent did · +17mRemoved the file from tracking, committed the .gitignore change alone, and pushed successfully to the remote branch.
- +17mOutcome · +17m5/5 parallel subagent simplification tasks completed and committed; messenger feed file untracked, .gitignore updated, and changes pushed to arnav/code-simplify branch.
VERDICT
I'd specify the correct subagent type ('worker') upfront in my first prompt since I wasted a couple of tries spawning nonexistent agent names before it worked. Once the right agent type was found, the parallel messenger-coordinated approach worked well — all 5 plans finished and committed independently. The only manual fix needed was a small git flow correction when .gitignore conflicted with a direct file add.
