Tamper-evident audit trails for ADK agents via asqav

[jagmarques]

Built an integration that signs every ADK tool call with ML-DSA-65 (quantum-safe). Each action gets a cryptographic signature chained to the previous one, creating a tamper-evident audit trail.

The hook sits in before/after tool callbacks:

import asqav
from asqav.extras.google_adk import AsqavCallback

asqav.init(api_key="sk_...")
callback = AsqavCallback()

agent = Agent(
    model="gemini-2.0-flash",
    before_tool_callback=callback.before_tool,
    after_tool_callback=callback.after_tool,
)

Every tool execution gets signed. The chain is exportable as JSON for compliance teams. Useful if you are building ADK agents for finance, healthcare, or any domain where EU AI Act Article 12 applies.

Signing tool calls with a post-quantum scheme like ML-DSA-65 and chaining them into an exportable audit trail is a smart angle for the EU AI Act Article 12 use case, nice work hooking it in cleanly through before/after_tool_callback. Closing this as Show and Tell since it's a third-party SDK rather than an ADK core issue, that way it stays visible. Keep the compliance-tooling posts coming.
