HumanLayer repo
An open source human in the loop layer that pauses an AI agent before a risky action and asks a real person to approve it over Slack, email, or SMS.
What it does for you: This is the missing piece between Axion's automations and YY's own approval rules. Right now GHL writes, Ouria drip sends, and publish actions all depend on YY remembering to say CONFIRM in chat. HumanLayer turns that into a structured approval step with a real audit trail, which is exactly the shape of the two confirmation rule already written down for GHL.
In practice: Feels like it was built for exactly YY's approval habit, almost too on the nose.
For: Both runtimes. Ships Python and TypeScript SDKs plus a webhook API, so it slots into Claude Code driven Axion flows or a standalone Hermes service the same way.
Verdict: test first. Scores highest this issue at 29 of 35 but still below the 31 point bar this issue is holding for build now, the fit to YY's own approval rules is strong enough to warrant a real test, not a cold build.
