Prerequisites
User must provide a Task Contract:
OUTCOME: [What success looks like - measurable]
EXCLUSIONS: [What I will NOT do]
DURATION: [Time limit, e.g., "1 hour"]
GUARDRAILS: [Hard limits - code/logic to never touch]

1. [Task 1] - [estimated time]
2. [Task 2] - [estimated time]
...
Estimated total: X mins
Strategy: [sequential/parallel/hybrid]
