Describe the feature

Request for a small example (or docs note) showing AffixIO as a tool input guardrail: prove a host-side action completed before a sensitive tool runs.

AffixIO proves a host-side ACTION completed (signed yes/no). PII stays on the host. Not person/age/KYC.

Sit: before an agent runs a sensitive tool (spend, DB admin, destructive API), AffixIO can gate/prove the action on the host.

You already ship tool_input_guardrail / examples/basic/tool_guardrails.py. AffixIO would plug in there: tripwire if the host proof is missing or rejected.

Install

bash
npm i affixio
npm i @affixio/[email protected]
