>Pi extension for async subagent delegation with truncation, artifacts, and session sharing
Builtin agents:
- scout: Fast local codebase recon: relevant files, entry points, data flow, risks.
- researcher: Web/docs research with sources and a concise research brief.
- evidence-auditor: Independently checks whether important research claims are supported by their sources.
- worker: Implementation work. Edits files, validates, escalates unapproved decisions instead of guessing.
- reviewer: Read-only code review against the task/plan, tests, edge cases, and simplicity.
- oracle: A second opinion before acting. Challenges assumptions without editing.
- delegate: A lightweight general delegate that behaves close to the parent session.

Pig Subagents Setups? What are some of the subagent patterns being used for development and Pig? I've used nicobailon/pi-subagents in my pi workflow and it's been great - relatively issue free. I understand that I can use this extension with Pig, but I've noticed that background agents error out - and I'm wondering if people are still using the same subagent extensions, some are using the refactored pigpen subagents piglet (github.com/MichaelKinsy/pigpen/tree/main/components/subagents#readme)? Just curious.
