pi-decision-graph

Records the agent's decisions — what it did, why, and which files it touched — into a project-local SQLite store (.pi/decision-graph.db), so later sessions can query the history instead of re-deriving it.

Install

pi install npm:@smayan-kulkarni/pi-decision-graph

What it does

• Captures every assistant Decision (message + tool calls) as it happens, no extra model calls.
• Registers record_decision_why, so the agent can record its own rationale in its own words.
• Once the store has Decisions, registers query_decisions, letting the agent ask "why did this file/line change?" and get the answer from history instead of re-reading diffs.
• Nudges the agent to consult the graph after compaction, when raw context is gone but the store isn't.

Requires Node ≥22.19 (for node:sqlite) — already satisfied by any Pi install.

No configuration needed. The store lives at .pi/decision-graph.db in the project.
