# Session Analysis Knowledge base for interpreting clens distilled session data. This skill provides schema documentation and analysis guidance for the `DistilledSession` JSON files produced by `clens distill`. ## What is clens? clens captures AI agent sessions (Claude Code) as local JSONL event streams via hooks. The `distill` command processes raw events through 23 extractors into a single structured JSON file containing stats, backtracks, decisions, file maps, git diffs, edit chains, diff attribution, reasoning traces, user messages, summaries, timelines, plan drift, active duration, agent tree, agent distillation, agent enrichment, aggregate team data, team metrics, decisions (team), summary (team), communication graphs, communication sequences, agent lifetimes, and journey data. ## Pillars - [Distill Schema](distill-schema.md) -- Complete type-annotated schema for every field in the distilled JSON output - [Interpretation Guide](interpretation-guide.md) -- How to read metrics, reference ranges, pattern interpretation, and actionable analysis techniques ## Key Conventions - **All timestamps** are Unix milliseconds (`number`). Convert with `new Date(t)` for human-readable output. - **Cost estimates** are USD approximations based on token heuristics (~20% margin). Not billing-accurate. - **Distilled files** live at `.clens/distilled/{sessionId}.json`. Raw events at `.clens/sessions/{sessionId}.jsonl`. - **Session IDs** are UUIDs. Use first 8 characters for display (e
