A valve or shutter you have switched on (P, T, C)Tokens are attribute keys: identity red, content indigo, tool details teal, the rest stoneSmallest falls first: identity through slot 1, content through slot 2 unless the shutter covers itTwo gates. Claude Code only sends prompt text with OTEL_LOG_USER_PROMPTS=1 and tool details with OTEL_LOG_TOOL_DETAILS=1. Then Aftertrace, before anything is written, deletes 6 identity keys always and 41 content keys and 4 key prefixes unless you run with --store-content, from every resource, span, span event, log record and metric point. Tool details are not content keys, so when the source sends them they are kept.
