PRISM

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.
