This benchmark measured an earlier version of the skill.
One of 15 test cases the skill fixed. Same model, same prompt, with and without the skill.
What exact command should be executed during setup to register the git pre-commit hooks in .git/hooks/pre-commit for claude-night-market?
| Checked | Without skill | With skill |
|---|---|---|
| Directs executing uv run pre-commit install to register git hooks | Missed | Passed |
The instructions your model reads when the skill loads.
Recreate a working claude-night-market development environment from a bare machine, verify it in under an hour, and avoid the traps that have broken it before. Everything below was verified against the repo on 2026-07-02 (v1.9.15).
One rule dominates: every Python tool runs through uv run. uv is
Astral's Python package and environment manager. On first uv run it
creates .venv/ and syncs it from uv.lock. Never install repo
dependencies with bare pip.
Install in this order. "via uv" means the tool resolves from uv.lock
automatically. There is no manual install step for those rows.
| # | Tool | Required? | Install hint | Verify command |
|---|---|---|---|---|
| 1 | uv | REQUIRED | official installer at astral.sh/uv | uv --version |
| 2 | Python 3.12 | REQUIRED | uv python install 3.12 | python3 --version |
| 3 | make + bash | REQUIRED | GNU make 3.82+ (Xcode CLT ships 3.81, which ignores .SHELLFLAGS; brew install make, run gmake) | make --version |
| 4 | ruff >=0.14.13 | via uv | none (dev dependency in uv.lock) | uv run ruff --version |
| 5 | bandit | via uv | none (pre-commit env is pinned separately, see traps) | uv run bandit --version |
| 6 | mypy >=1.13 | via uv | none | uv run mypy --version |
| 7 | pre-commit >=4 | via uv | uv run pre-commit install | uv run pre-commit --version |
| 8 | Python 3.9 | optional | uv python install 3.9 | uv venv --python 3.9 /tmp/py39-check |
| 9 | node + npm | optional | needed for conjure Gemini delegation | node --version |
| 10 | Rust + cargo | optional | rustup (only for make skrills-build) | cargo --version |
| 11 | skrills binary | optional | make skrills-build or make skrills-install | make skrills-verify |
| 12 | mdbook | optional | cargo install mdbook; builds book/ | mdbook --version |
| 13 | gh CLI | optional | cli.github.com (releases and Discussions) | gh --version |
