Build Log 10: Integration Day.

Mar 5 — connecting the agent to everything else.

An agent that can only talk to itself is a toy. An agent that can talk to your tools is a teammate.

Notion and Linear

Notion OAuth with 3 agent tools — search pages, read content, create pages. Linear popup OAuth with task sync. Both follow the same pattern: OAuth flow, store tokens encrypted, expose capabilities as agent tools. The agent can now read your docs and manage your tasks without leaving the chat.

Eight Multi-Agent Patterns

Built all 8: handoff, review, orchestrator, critic loop, A2A delegation, agent-as-tool, coordinator, and synthesizer. These aren't theoretical — they're the actual patterns teams use when multiple agents collaborate. One agent drafts, another reviews. One orchestrates, others execute. The workspace supports all of them.

Verification Loop

The agent now runs lint, typecheck, and tests before opening a PR. If something fails, it fixes the issue and tries again. No more PRs that break CI on the first commit. This alone probably saves more time than any other feature shipped this week.

Security

Auth on all routes — no more unauthenticated endpoints hiding in the codebase. AES-256-GCM encryption for stored secrets. RLS restrictions tightened. Audit logs with RBAC. API key authentication for programmatic access.

The agent can now talk to your tools, verify its own work, and do it all securely. That's the difference between a demo and a product.
