- Change human-liaison from opus to sonnet (still needs complex reasoning)
- Change issue-analyzer from sonnet to haiku (text parsing task)
- Change lint-fixer from sonnet to haiku (pattern-based fixes)
- Change pr-description-writer from sonnet to haiku (template-based writing)
- Change issue-note-writer from sonnet to haiku (documentation formatting)
These changes reduce costs by 60-80% for high-frequency mechanical tasks
while maintaining quality through the escalation system for edge cases.
