# Session Compare Compare two distilled clens sessions side-by-side to identify performance differences and determine which approach was more effective. ## Variables TARGET: $ARGUMENTS ## Instructions ### 1. Resolve the Sessions - If TARGET contains two session IDs (space-separated), use those - If TARGET is `--last 2` or `--last`, find the two most recent distilled sessions: - List files in `.clens/distilled/` sorted by modification time - Use the two most recently modified `.json` files - If TARGET contains only one session ID, use it as Session A and the most recent other session as Session B - If fewer than 2 distilled sessions exist, tell the user: > Need at least 2 distilled sessions to compare. Run `clens distill` on more sessions first. Label the older session as **Session A** and the newer as **Session B**. ### 2. Read Both Sessions - Read both distilled JSON files from `.clens/distilled/{sessionId}.json` - Parse both as `DistilledSession` objects - Load the `session-analysis` skill for schema and interpretation context ### 3. Generate the Comparison Report Use the following template. Compute all deltas and provide analysis. --- ## Session Comparison: {session_a_id first 8 chars} vs {session_b_id first 8 chars} ### Metrics Comparison | Metric | Session A | Session B | Delta | Better | |--------|-----------|-----------|-------|--------| | Duration | {a.summary.key_metrics.duration_human} | {b.summary.key_metrics.duration_human} | {difference} | {a
