PRISM
Session intelligence for Claude Code
PRISM reads Claude Code's session JSONL files and tells you exactly why your tokens are disappearing. Found on a real machine: 6738% CLAUDE.md re-read cost, rules silently ignored mid-session, migration file edits that violated project rules, retry loops with no diagnosis. Health scores A-F across 5 dimensions + concrete CLAUDE.md fix recommendations. 100% local — no API key, no telemetry.
Hi Everyone! I Built PRISM after hitting Claude Code token limits and having no idea where my tokens were going. Turns out the session data is all there in JSONL files, PRISM reads
them and surfaces what's wrong.
Found 6738% CLAUDE.md re-read cost on my own machine.
Runs 100% locally.
MIT license.
Would love your feedback.
