message.usage.cost.total fields. - Tool Usage Breakdown: Aggregate which tools were called and how often within any session transcript. - Use Case: A user asks "what did we decide about the database schema last Tuesday?" You locate sessions from that date, extract the user and assistant text messages, and search for the relevant discussion. ## Quick Start Search my session logs for any past conversation where we discussed database migration and summarize what was decided.High-intent search queries and answers about installing and using this skill.
Use ripgrep to search across all session files for a phrase, then use jq to extract readable text by filtering messages where content type equals text. Session transcripts live in the agent's sessions directory as one JSON object per line.
Filter with jq by selecting entries where message.role equals user, then iterate over message.content items where type equals text and print the text field. This excludes assistant replies, thinking blocks, and tool calls.
Yes. Each message entry contains a message.usage.cost.total field. Use jq with the slurp flag to sum all cost values in a session file, or loop over all session files to build a daily cost summary grouped by date.
The workflow requires jq for parsing and filtering JSON lines and ripgrep (rg) for fast text search across files. Standard Unix utilities like head, sort, awk, and uniq are used for aggregation and summaries.
Session files contain mixed entry types, including session metadata entries without a message field. Ensure your filter selects type message entries first, and verify you are reading the correct session ID from the sessions.json index.
