README

pi-session-router

Pi extension that automatically decides whether a new prompt belongs in another existing session.

Behavior

  • intercepts a newly submitted user prompt
  • gathers recent project sessions
  • asks an LLM to choose the most relevant existing session, if any
  • switches to that session before continuing
  • if no better session exists, keeps the current one

Commands

/session-router on
/session-router off
/session-router toggle
/session-router status
/session-router threshold 0.80
/session-router notices off

Notes

  • this is an opinionated workflow extension
  • it uses an unsupported internal AgentSession hook to switch sessions invisibly during prompt interception
  • it can stay in the current session, switch to another local session, or start a new session when no good match exists
  • it keeps a lightweight cache at ~/.pi/agent/session-router-cache.json
  • routing heuristics now use exact informative-token overlap instead of loose substring matching, which avoids false CURRENT decisions on unrelated prompts
