Hey @itlasso — thanks for this! Two things to fix:

1. Malformed filename — the agent file ended up named feat: add CMS Accessibility Specialist agent instead of a proper path like engineering/engineering-cms-accessibility-specialist.md. Looks like the commit message got used as the filename accidentally.

2. Rebase needed — I just merged feat: add CMS Developer agent (WordPress & Drupal) #318 (CMS Developer), so this will need a rebase to resolve the conflict on that file.

Once those are sorted, this is good to go!

@msitarzewski rebased and added the vibe field — ready for review. Thanks!

@msitarzewski fixed the filename and moved it to the correct path, and rebased — should be good to go now. Thanks!

Issue 1 — Section headers on new agent don't match required template format (score: 100)

engineering-cms-accessibility-specialist.md uses non-standard heading text throughout. The convert.sh script matches these headers exactly to split agents into tool-specific formats.

Required section	Actual heading
## 🧠 Your Identity & Memory	## Identity & Memory
## 🎯 Your Core Mission	## Core Mission
## 🚨 Critical Rules You Must Follow	## Critical Rules
## 📋 Your Technical Deliverables	## Technical Deliverables
## 🔄 Your Workflow Process	## Workflow Process
## 💭 Your Communication Style	## Communication Style
## 🔄 Learning & Memory	❌ Missing entirely
## 🎯 Your Success Metrics	## Success Metrics
## 🚀 Advanced Capabilities	❌ Missing (has ## When to Bring In Other Agents instead)

Each heading needs the correct emoji prefix and full Your phrasing per the CONTRIBUTING.md template (§ Agent File Structure). This matches the same issue flagged in PR #357 and #356 from the same author.
