## Summary
Major overhaul of build pipeline and all command files — sub-agents, task tracking, structured interactions, learnings feedback loop, and persona removal.

## What Was Done
- Condensed build command (251→~150 lines), then evolved through multiple iterations
- Added sub-agents for shape/plan/simplify/verify steps in build pipeline
- Added TaskCreate/TaskUpdate for persistent progress checklist
- Added AskUserQuestion to shape-issue, plan-stories, plan-issues, review
- Extended plan-issues to read .mantle/learnings/ for retrospective recommendations
- Removed persona framing from all 15 command files
- Fixed CLI bugs: issue lookup fallback, skill validation error handling, exception syntax
- Added mantle list-skills CLI command
- Shortened filename slugs from 50 to 30 chars
- All command references in build use full file paths
- Released v0.7.3 through v0.7.8

## Decisions Made
- Sub-agents for build steps (research-backed: focused context > file delegation)
- TaskCreate over markdown checklists (persistent UI above query bar)
- AskUserQuestion over free-text prompting (structured choices)
- Direct task descriptions over persona framing (Claude 4.x research)
- Learnings flow into plan-issues (closes feedback loop gap)

## What's Next
- Test build pipeline with sub-agents on a real project
- Monitor whether steps still get skipped

## Open Questions
- None
