Nerf receipts: your model-quality trend card

!`node "${CLAUDE_SKILL_DIR}/../../nerf-receipts.js" --render 2>/dev/null || node "${CLAUDE_PLUGIN_ROOT}/nerf-receipts.js" --render`

The card above is your own per-session flight recorder, aggregated across your recent Claude Code sessions and keyed by model id and Claude Code version: failure rate, edit churn, and tokens per task, each with a sparkline. It is recorded quietly in the background by the `nerf-receipts` hooks as you work.

Briefly interpret it for the user: call out the headline averages, and if a ⚠ shift line is present, restate which metric moved, by how much, and across which model change; that is the receipt that a quality shift is real, not a vibe. If the card says data is still accumulating, tell them to keep working and check back after a few more sessions. Keep it short and do not re-run any commands.
