README

@fractaal/pi-context-window

A portable Pi extension that caps the active model's resolved context window. Pi still owns reserve tokens, compaction, overflow recovery, and continuation.

Commands:

/context-window shows the current model budget.
/context-window 128k sets the current session override.
/context-window default clears the session override.
/context-window-default 128k sets the current model's global default.
/context-window-default default clears that global default.

The session override is persisted in the Pi JSONL. Global defaults are stored in the same profile directory as models.json, using an atomic local JSON file.
