pi-reuse-model

A pi extension that starts every fresh session (/new, reopening a workspace) on the model and thinking level you last used in this workspace, instead of the configured defaults.

Part of the my-pi-plugins monorepo.

Install

pi install npm:pi-reuse-model

Or load it with --extension ./src/index.ts, like any pi extension.

Behavior

• Changing the model or thinking level records the selection in ~/.pi/agent/pi-reuse-model.json, keyed by workspace directory.
• On session_start (startup or new) the recorded model is restored through pi.setModel(), then the recorded thinking level through pi.setThinkingLevel(). resume/fork already restore from the session transcript and are left alone.
• Restore is skipped when the command line pins a model (--model, --models, --provider) or the session already runs the recorded model or level. A model missing from the registry or lacking provider auth falls back to the resolved default while the thinking level still restores; an unknown recorded level is dropped.

Similar extensions

pi-remember-model and pi-remember-last-model keep a single global slot; this one remembers per workspace.

Development

pnpm install
pnpm verify   # fmt + lint + typecheck + test (all packages)
