Sweep plugins, skills, agents, commands, and hooks after a model release or Claude Code version bump. Use when upstream ships. Do not use for routine edits; use night-market-change-control.
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
# Night Market Model and Harness Updates When Anthropic ships a model or Claude Code ships a version, the pins scattered through this repo rot silently. This skill runs the sweep that finds the rot, researches what actually changed, applies the updates, and records where upstream stood so the next run reports only the new delta. The watermark is the point. Without it every audit restarts from zero and re-derives the same answer by hand. `.claude/upstream-baseline.json` holds the last recorded upstream state, and each run diffs against it. ## When to run | Trigger | Signal | |---------|--------| | Model release | A tier or model ID ships that the ledger does not record | | Harness release | `claude --version` differs from the ledger | | Scheduled check | Monthly, to catch a release nobody noticed | ## The five steps Run them in order. Each one gates the next. ```bash # 1. Detect. Deterministic, no model in the loop. python3 scripts/check_upstream_drift.py # 2. Research what changed (only when step 1 reports drift). # Release notes and model cards are mandatory sources. # 3. Map findings onto asset classes. # 4. Sweep the implicated classes. …

How to install
mdr add athola/claude-night-market/night-market-model-and-harness-updates@sha256:68cca69596fe2036The line at the top of this page pins the label git:20260814.0f2ecb7, 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.
