cook-hard

Ultrathink to plan and implement these tasks with maximum verification: $ARGUMENTS

Mode: HARD - Extra research, detailed planning, mandatory reviews.

⚠️ MUST READ Before Starting

IMPORTANT: You MUST read these shared protocols before any code changes. Do NOT skip.

• ⚠️ MUST READ .claude/skills/shared/anti-hallucination-protocol.md — Assumption validation, evidence chains, context anchoring
• ⚠️ MUST READ .claude/skills/shared/knowledge-graph-template.md — Per-file analysis structure (for investigation phases)

Core Rule: Verify every assumption with actual code evidence before making changes. Search for all usages, read implementations, trace dependencies. If confidence < 90%, investigate further or ask user.

Workflow

1. Deep Research Phase

• Launch 2-3 researcher subagents in parallel covering:
  • Technical approach validation
  • Edge cases and failure modes
  • Security implications
  • Performance considerations
• Use /scout-ext for comprehensive codebase analysis
• Generate research reports (max 150 lines each)

2. Comprehensive Planning

• Use planner subagent with all research reports
• Create full plan directory with:
  • plan.md - Overview with risk assessment
  • phase-XX-*.md - Detailed phase files
  • Success criteria for each phase
  • Rollback strategy

3. Verified Implementation

• Implement one phase at a time
• After each phase:
  • Run type-check and compile
  • Run relevant tests
  • Self-review before proceeding

4. Mandatory Testing

• Use tester subagent for full test coverage
• Write tests for:
  • Happy path scenarios
  • Edge cases from research
  • Error handling paths
• NO mocks or fake data allowed
• Repeat until all tests pass

5. Mandatory Code Review

• Use code-reviewer subagent
• Address all critical and major findings
• Re-run tests after fixes
• Repeat until approved

6. Documentation Update

• Use docs-manager to update relevant docs
• Use project-manager to update project status
• Record any architectural decisions

7. Final Report

• Summary of all changes
• Test coverage metrics
• Security considerations addressed
• Unresolved questions (if any)
• Ask user to review and approve

When to Use

• Critical production features
• Security-sensitive changes
• Public API modifications
• Database schema changes
• Cross-service integrations

Quality Gates

Gate	Criteria
Research	2+ researcher reports
Planning	Full plan directory
Tests	All pass, no mocks
Review	0 critical/major findings
Docs	Updated if needed

IMPORTANT Task Planning Notes

• Always plan and break many small todo tasks
• Always add a final review todo task to review the works done at the end to find any fix or enhancement needed
