What is mise-uv-install-test?

A setup and test workflow for Python projects managed with uv and mise. uv installs and synchronizes Python dependencies, while mise installs the pinned development tools defined by the project.

Use it to install the required toolchain, synchronize dependencies from the lockfile, run pytest tests, and report which step failed.

It provides a repeatable way to prepare the project's environment and check that it works. This reduces setup differences between machines.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add GuilhemBusset/agentic-or-workshop --skill mise-uv-install-test

Clone the repo

git clone --depth 1 https://github.com/GuilhemBusset/agentic-or-workshop

Made for: Codex.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00049	$0.00317
Opus 5	$0.00024	$0.00159
Sonnet 5	$0.00010	$0.00063
Haiku 4.5	$0.00005	$0.00032

Security

Grade A, and why

mise-uv-install-test scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/install_and_test.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Mise UV Install Test

Run the repository setup and verification flow exactly in this order.

Workflow

Activate mise in the shell:

eval "$(mise activate bash)"

Install the pinned toolchain from .mise.toml:

mise install

Ensure uv is available. Prefer uv on PATH; otherwise use mise exec:

uv --version || mise install uv

Sync project dependencies from uv.lock:

uv sync

Fallback for restricted sandboxes:

UV_CACHE_DIR=/tmp/uv-cache uv sync

Run tests:

uv run pytest

Fallback for restricted sandboxes:

UV_CACHE_DIR=/tmp/uv-cache uv run pytest

Scripted Path

Use scripts/install_and_test.sh to run the full workflow in one command:

bash skills/mise-uv-install-test/scripts/install_and_test.sh

Reporting

Report:

whether toolchain install succeeded,
whether dependency sync succeeded,
test summary (N passed, failures, and warnings).

If a step fails, include the failing command and the shortest actionable fix.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
