Thanks! This was step one in my daily driver stack - better observability. I also bundled up a bunch of other observability services in https://github.com/simple10/agent-super-spy so I can see the raw prompts and headers.

The next big layer for my personal stack is full orchestration. Something like Paperclip but much more specialized for my use cases.

I'm not actually reading the jsonl files. Agents Observe just uses hooks and sends all hook data the server (running as a docker container by default).

Basic flow:

1. Plugin registers hooks that call a dump pipe script that sends hook events data to api server

2. Server parses events and stores them in sqlite by session and agent id - mostly just stores data, minimal processing

3. Dashboard UI uses websockets to get real-time events from the server

4. UI does most of the heavy lifting by parsing events, grouping by agent / sub-agent, extracting out tool calls to dynamically create filters, etc.

It took a lot of iterations to keep things simple and performant.

You can easily modify the app/client UI code to fully customize the dashboard. The API app/server is intentionally unopinionated about how events will be rendered. This was by design to add support for other agent events soon.

I hit a lot of limits on Pro plan. Upgraded to Max $200/mo plan and haven't hit limits for awhile.

It's super important to check your plugins or use a proxy to inspect raw prompts. If you have a lot of skills and plugins installed, you'll burn through tokens 5-10x faster than normal.

Also have claude use sub-agents and agent teams. They're significantly lighter on token usage when they're spawned with fresh context windows. You can see in Agents Observe dashboard exactly what prompt and response claude is using for spawning sub-agents.

I'd bet there are many. I know a few teams with spends in the thousands of dollars per day. It sounds crazy, but not too unrealistic.

I've been having the same issue. It's such a shame because it is levels above the other AIs

Sub-agent trees are fully tracked by the dashboard. When an agent is spawned, it always has a parent agent id - claude is sending this in the hooks payload. When you mouse over an agent in the dashboard, it shows what agent spawned it. There currently isn't a tree view of agents in the UI, but it would be easy to add. The data is all there.

[Edit] When claude spawns sub-agents, they inherit the parent's hooks. So all sub-agents activity gets logged by default.
