The 2026 development
Anthropic introduced Claude Duet as an assistant able to reach out before being prompted.
The governance gap
Initiative is a standing authority to interrupt and act. A proactive agent needs a reason, a relevance check, a quiet default and a hard limit on what it may do without a fresh instruction.
Where CAIN-42 fits: Moat 7 — Autonomous Trust Control Loop
Core question: Can verified experience change future trust? Monitor, detect, contain, recover, and re-authorise from observed outcomes.
Separate initiative from authority: the agent may propose, but a standing lease defines what it may execute unattended, and that lease is reviewable and revocable.
How the wiring works
- Define the proactive lease: topics, sources, actions and frequency.
- Check relevance and consent before reaching out.
- Require a fresh grant for any new class of action.
- Let the user revoke and audit the lease.
What is real today
LIBRARY Production code and tests exist in this repository; there is no hosted route for this exact use.
The lease engine is real. No proactive assistant product is operated here.
| Component in this repository | What the module says it is |
|---|---|
cain/argus/lease.py | CAIN ARGUS — the Autonomous Assurance Lease (Prompt 14, section 9). |
cain/argus/reauthorization.py | CAIN ARGUS — continuous re-authorization engine (Prompt 14, sections 8-9). |
cain/argus/state_machine.py | CAIN ARGUS — assurance state machine (Prompt 14, section 16). |
Descriptions are the first line of each module's own docstring, read without importing it. A module path is a pointer into this repository, not a hosted endpoint. Its existence is checked by the test suite; its status for this use is the label above.
