Session Policies Overview

Agent calls usePermission() with instruction
        ↓
MEE submits to blockchain
        ↓
Smart contract checks:
  ✓ Is this contract/function allowed?
  ✓ Do parameters pass all policy rules?
  ✓ Is the session still valid (time)?
  ✓ Is usage limit not exceeded?
        ↓
All checks pass → Execute
Any check fails → Revert

actions: [{
  chainId: base.id,
  actionTarget: UNISWAP_ROUTER,
  actionTargetSelector: swapSelector,
  
  // Time bounds
  validAfter: now,
  validUntil: now + 7 * DAY,
  
  // Usage limit
  usageLimit: 100n,
  
  // Parameter rules
  actionPolicies: [
    getUniversalActionPolicy({
      valueLimitPerUse: 0n,
      paramRules: { /* spending limits */ }
    })
  ]
}]
