What I Learned

• Optimistic concurrency: Distributed locks and version vectors prevented stale graph writes during high-burst collaboration.
• Deterministic execution: Prompt adapters around tool calls reduced model confusion and improved reliability.
• Operational guardrails: Token and latency observability were required before scaling concurrent sessions.

Implementation Notes

• Canvas events stream into a graph ingestion service.
• Graph context is embedded and indexed for retrieval.
• Tool runner executes selected actions with strict output contracts.
• Session gateway persists state snapshots and merges collaborator edits.

Code Snippet

type ToolCall = { name: string; args: Record<string, unknown> };

export async function runTool(call: ToolCall) {
  const schema = toolRegistry[call.name];
  const args = schema.parse(call.args);
  const result = await handlers[call.name](args);
  return { name: call.name, result };
}
