Cynos Turns “Done” Into Evidence

Cynos targets the most dangerous failure mode in coding agents: confidently claiming completion without proving the requested outcome exists where users need it.

• –Evidence is tied to actual reads, writes, commands, tests, and deployment actions
• –Checkpoints make “done” an auditable claim rather than a conversational summary
• –The six-boundary framing exposes why a passing local test does not prove a production release works
• –This shifts agent evaluation from output quality toward traceability, state verification, and operational reliability
• –The approach is especially useful for long-running, autonomous coding workflows where context and assumptions drift
