Hands-on verificationComplete on demand · Suggestions15 minutes

Write a seven-field compressed state for a conversation containing two constraints, an unknown tool outcome, and extensive logs.

Expand acceptance requirements and checkpoints
  • Both constraints remain intact
  • Unknown results are still marked as unknown
  • Key facts can be traced

Key inspections

  • Able to distinguish between facts, assumptions and authorizations
  • There are citations to read back and a budget to reserve
  • Ability to test for behavioral degradation caused by compression
