A Pi coding agent extension for direct model switching.

It provides one tool, switch_model, for model listing, search, and direct switching.

Foreground orchestration now lives in pi-orchestrate.

pi install npm:pi-model-switch

Restart Pi to load the extension.

Parameters:

• action: list | search | switch
• search?: query for search and switch
• provider?: provider filter

Behavior:

• list: shows available authenticated models
• search: filters by provider, id, or name
• switch: resolves aliases first, then does exact or partial model matching

Define aliases in:

~/.pi/agent/extensions/model-switch/aliases.json

{
  "cheap": "google/gemini-2.5-flash",
  "coding": "anthropic/claude-opus-4-5",
  "budget": ["openai/gpt-5-mini", "google/gemini-2.5-flash"]
}

Rules:

• top-level value must be an object
• alias names must be non-empty strings
• each target must be provider/modelId
• string alias: one exact model target
• array alias: fallback chain; first available authenticated target wins
