What it does
Use Local Venv is an agent skill from AliceJump/ok-end-field. Prefer the repository-local Python virtual environment for coding-agent work. Use when running Python scripts, tests, linters, formatters, package installs, dependency checks, or any Python command in a repo that uses uv and a .venv; keep pyproject.toml plus uv.lock authoritative and avoid global Python drift.
Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Development, covering Linting and formatting. It works with Python. The repository describes itself as: 终末地 End Field Automation 基于ok-script开发的自动化. The licence is AGPL-3.0.
When your agent uses it
- Running Python scripts
- Package installs
- Dependency checks
- Any Python command in a repo that uses uv and a .venv
Example prompts
- “/use-local-venv”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 54e11e5. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
uv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Use Local Venv loads about 688 tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 287 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- use-local-venv
- description
- Prefer the repository-local Python virtual environment for coding-agent work. Use when running Python scripts, tests, linters, formatters, package installs, dependency checks, or any Python command in a repo that uses uv and a .venv; keep pyproject.toml plus uv.lock authoritative and avoid global Python drift.
Use Local Venv
Overview
Use the project .venv for Python commands so agent work uses the same dependencies as the repository instead of the global Python installation.
The .venv is created and synced by uv sync from pyproject.toml and uv.lock. In this repository, use uv sync --locked and uv run --locked ... so a verification command cannot silently rewrite the lockfile or resolve different dependency versions.
Rule
- Run from the repository root unless the script explicitly supports another working directory.
- Prefer
uv run --locked python ...; it selects the repository.venvwithout activation and verifies the lockfile. - Use the direct
.venvinterpreter only for bootstrap diagnostics whenuvis unavailable; it is not a valid formal test or lint entry point. - Do not fall back to global Python in this repository. If
uvor.venvis missing, runuv sync --lockedor report the environment problem instead of executing with unknown dependencies. pyproject.tomlanduv.lockare dependency sources of truth.requirements.txtis a publishing derivative and must not be hand-edited.
PowerShell
Normal commands:
uv sync --locked
uv run --locked python -m unittest tests.TestCheckLang -v
uv run --locked python -m py_compile path/to/script.pyIf a Windows shell uses a legacy code page, run Python in UTF-8 mode for scripts or tests that read UTF-8 files without an explicit encoding or emit Chinese/emoji logs:
uv run --locked python -X utf8 -m unittest tests.TestZipLineConfig -vWithout UTF-8 mode, a test can exit successfully while its logging handler prints UnicodeEncodeError, or a text-reading script can fail with UnicodeDecodeError.
Direct-interpreter bootstrap diagnostic after confirming it exists:
& ".\.venv\Scripts\python.exe" --versionPOSIX Shells
uv sync --locked
uv run --locked python -m unittest discover -s testsTests
- Full repository suite:
scripts/testing/run_tests.ps1(which usesuv run --locked). - Focused unittest:
uv run --locked python -m unittest tests.TestModule -v. - Do not use a direct
.venvinterpreter invocation as formal verification; all formal checks use a lockeduventry point. - Preserve and report pre-existing independent failures; do not hide them by switching interpreters or dependencies.
