A subagent is a built-in specialist. When a question is bigger than a single lookup, the analyst you are talking to (the parent) can send one out to do the noisy work on its own, then take back a single brief. You do not configure these specialists. The analyst picks one when the job matches. Use a specialist for a long filing pull, a valuation, a screen, or an ownership sweep. Skip it for a quote or one line on a statement. That only adds a wait.

​
How they work

A separate workspace

Raw pages, multi-year statements, and screener lists stay with the specialist. The parent only sees the brief.

A fresh start

The specialist does not see the rest of the chat. The parent writes a self-contained request: tickers, time window, and what to bring back.

Same model

It uses the model and reasoning-effort setting you picked, and it shares that turn’s usage.

The parent stays in control

It can read your notes and use connected MCP servers. Edits and skills stay with the parent, and still go through approval.

​
The four specialists

They are organized by mission. None of them is a bull-case or bear-case agent.

Researcher

News, filings, transcripts

What’s going on with this week? Check the latest filing and the call.

Analyst

Quality, valuation, DCF, multiples

Is expensive at today’s price? Run a DCF and compare the multiple to its peers.

Scout

Screening and idea generation

Find undervalued small-cap energy names with high free-cash-flow yield.

Ownership

13F, Form 4s, congressional trades

Has anyone notable been buying or selling ? Check 13F changes and recent Form 4s.
You can name the specialist in the question, or put two jobs in one message. There is no /researcher trigger. / is for skills and MCP servers.

​
Subagents vs skills

Use a specialist

A built-in mission for one noisy job: research, valuation, a screen, or ownership. You write nothing; the analyst picks one.

Use a skill

A process you wrote and want followed every time, even when the company changes.
A skill can still cause a delegation: on is the parent’s process. Pulling several years of statements can still go to the Analyst specialist.
You cannot write your own specialist. If you want the analyst to follow your process, write a skill or ask the analyst to draft one.

​
What you see

A specialist appears as a card labeled Researcher, Analyst, Scout, or Ownership. The card opens while it works and collapses when it finishes. Expand it later to inspect the thinking and tool calls. Stopping the answer stops the specialist too.
