only cite sources for idaho - federal rules would go in the federal agency folder

these fractions (e.g. 52%) are federal parameters - put them in the federal agency folder and use a scale parameter

then separately add idaho to the existing smi parameter (4-person)

this has nothing on ages - always ensure each reference corroborates the parameter value (as well as each parameter value being corroborated by a reference)

just remove this if you're not actually implementing it. if we have a formula, users expect it to do something

no hard coded params! where did 0.5 come from?

MaxGhenis and others added 3 commits August 26, 2025 22:28
- Add eight_plus_person parameter for 8+ household income limits
- Create heating_season.yaml with start_month and end_month parameters
- Create weatherization_income_limit.yaml for 200% FPL limits
- Update variables to use parameters instead of hard-coded values
- Remove hard-coded months (10, 3) for heating season
- Remove hard-coded FPL values in weatherization eligibility
- Apply Black formatting to all modified files

These changes address domain validation issues by properly parameterizing all configurable values and ensuring maintainability.
After testing /review-pr on Idaho LIHEAP, found the coordinator was making direct edits instead of using specialized agents.

## New Agents Added
- policy-domain-validator: Federal/state separation, naming conventions
- reference-validator: Ensures references corroborate values
- parameter-architect: Extracts ALL hard-coded values to parameters
- ci-fixer: Manages CI/CD pipeline issues
- Multiple enhancement agents for edge cases, performance, documentation

## Command Improvements (/review-pr)
- MANDATORY agent usage - coordinator cannot make direct edits
- Explicit invocation templates for each agent
- Pre-flight checklist to ensure compliance
- Sequential execution with commits between phases

## Documentation
- agent-coordination.md: Anti-patterns and correct patterns
- agent-testing.md: TDD approach for agent development
- workflow.md: Multi-agent isolation patterns
- Test cases for validating agent behavior

The system now ENFORCES proper agent delegation rather than allowing shortcuts.
