Use uv for missing Python dependencies, task-scoped virtual environments, temporary execution, and non-preinstalled Python tools.
Install with Codex or Claude Copy this prompt, paste it into Codex, Claude, or another assistant, and let it review the skill page and install it for you.
Use agent-browser-cli to perceive and control the supervised Chrome browser inside the sandbox, interact with pages, capture screenshots/PDFs, inspect cookies/CDP/network/console state, and troubleshoot only when needed.
Use OWASP Amass for authorized asset discovery, domain enumeration, and DNS intelligence on in-scope targets.
Use apktool for authorized Android APK resource decoding, manifest review, smali inspection, rebuild checks, and static mobile artifact triage.
Use file, 7z, unzip, tar-compatible tools, hashes, and bounded shell inspection for safe triage of provided archives and unknown files.
Use binwalk for authorized firmware, binary blob, archive, filesystem, and embedded-content triage with bounded extraction and evidence handling.
Use the pwntools-provided checksec CLI for authorized ELF hardening review, mitigation checks, and binary triage evidence.

| description | Use uv for missing Python dependencies, task-scoped virtual environments, temporary execution, and non-preinstalled Python tools. |
Use uv for missing Python dependencies, task-scoped virtual environments, temporary execution, and Python tools that are not already preinstalled. The image is configured to prefer the existing /usr/bin/python3 and to avoid uv-managed Python downloads.
Before using uv to run or install a tool, load the dedicated skill for that tool when one exists. Do not use uvx, uv run --with, or uv tool install to recreate a bundled tool such as sqlmap, pwntools, checksec, or any tool listed by sandbox-shell.
Before constructing commands, use installed help as the source of truth:
uv --help
uv tool --help
uv pip --help
command -v <tool> and installed help before any install step.uv venv --python /usr/bin/python3 <dir> only when a script needs dependencies outside the bundled toolset.uv pip install --python <dir>/bin/python ....uvx --python /usr/bin/python3 <tool> or uv tool run --python /usr/bin/python3 <tool> only when no preinstalled equivalent exists.uv tool install --python /usr/bin/python3 --no-python-downloads <tool> only when repeated use is required and the tool is not already in the image.uv run --python /usr/bin/python3 --with <package> python ... only for missing dependencies or a deliberately isolated environment./usr/bin/python3; do not let uv download another Python unless the user explicitly asks.pip install unless the user explicitly asks and the reason is recorded.Create an isolated task environment:
uv venv --python /usr/bin/python3 .venv
uv pip install --python .venv/bin/python requests
Run one-off Python with a temporary dependency:
if python3 -c 'import requests' 2>/dev/null; then
python3 script.py
else
uv run --python /usr/bin/python3 --with requests python script.py
fi
Run a temporary CLI tool without installing it globally, only when it is not already bundled:
command -v ruff >/dev/null || uvx --python /usr/bin/python3 ruff --help
Install a persistent Python CLI tool only when it is absent and meant to stay available for repeated task use:
command -v <tool> >/dev/null || uv tool install --python /usr/bin/python3 --no-python-downloads <tool>
Report the uv command used, virtual environment or tool path, installed packages, and any reproducibility notes.
