Webhook & Event System

[antiv]

Summary

Configurable webhooks triggered on system events: agent response complete, error, RBAC denial, token budget exceeded, human approval needed. Support Slack, Discord, Teams, and generic HTTP POST.

Motivation

No agent framework does this well — first-mover advantage. Essential for ops teams monitoring production agents. Enables integration with any external system without polling.

Scope

• New webhooks table (url, events[], secret, active, project_id)
• Event types: agent.response, agent.error, rbac.denied, budget.exceeded, approval.requested, agent.config_changed
• Event bus (in-process, async) with retry logic (exponential backoff, max 3 retries)
• HMAC signature on payloads for verification
• Dashboard webhook manager: create, test, view delivery logs
• Pre-built payload templates for Slack/Discord/Teams

Acceptance Criteria

• Webhooks fire on configured events
• Retry logic with exponential backoff
• HMAC-signed payloads
• Dashboard CRUD + test delivery
• At least Slack and generic HTTP templates
