# Pi

> Delegate tasks or get a second opinion from Pi CLI. Infers mode (delegation vs validation) from prompt context. Detects available models at runtime via the CLI. Use when cross-validating code, plans, or architecture with Pi, or offloading work to it. Do not use when already running inside Pi CLI or for tasks that do not benefit from cross-model input.

# Cross-Agent Task Runner — Pi CLI

## Procedures

**Step 1: Self-Call Detection**

1. Check for `PI_AGENT` environment variable or `pi` in process ancestry.
2. If detected, stop and inform the user:
   "Cannot invoke Pi from within Pi. Use a different target CLI."

**Step 2: Execute Shared Procedure**

1. Read `references/shared-procedure.md` for the core workflow
   (mode inference, context gathering, prompt construction, result presentation).
2. Read `references/cli-pi.md` for Pi-specific flags, model selection
   heuristics, and version compatibility matrix.
3. Follow the shared procedure using the Pi-specific details.
