Show your personal model-quality trend card (failure rate, edit churn, tokens/task by model version).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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.Read the whole file at its exact version.
How to install
mdr add karanb192/claude-code-hooks/receipts@sha256:6ba5de4e82ae9407The line at the top of this page pins the label git:20260818.caa2d43, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
