Why it is on the list
The most mature subagent system; included in any paid Claude plan.
Facts with sources
- Pro at $20 is enough to try it out: on a real task the limits run out within a couple of hours, so plan the team budget from Max. Source (in Russian)
- The subscription gives you only Claude: you can’t switch models within it. Source (in Russian)
- On July 21 the system prompt was cut by about 80%: newer models handle context better than a list of rules. Source (in Russian)
- Anthropic asks for identity verification with a document and a selfie; corporate signs of use from Russia lead to loss of access. Source (in Russian)
Who it is for
- Engineer who knows the repo, branches, and terminal
