What it does
Crosvm Dev Container is an agent skill from google/crosvm, published by the product's own GitHub organization. Skill to assist with using the devcontainer tool for running builds, tests, and other tools in a consistent containerized environment.
Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in DevOps & Cloud. It works with Docker. The repository describes itself as: The Chrome OS Virtual Machine Monitor - Mirror of https://chromium.googlesource.com/crosvm/crosvm/. The licence is BSD-3-Clause.
When your agent uses it
- DevOps & Cloud work in your project
Example prompts
- “/crosvm-dev-container”
Requirements
- Docker
What it can do on your machine
Read from SKILL.md and the folder at commit 2c8433b. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Crosvm Dev Container loads about 345 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 136 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.

Crosvm Dev Container (tools/dev_container)
The tools/dev_container script is a wrapper used to run commands inside the official crosvm
development container. This ensures a consistent environment with all necessary dependencies
installed (such as compilers, libraries, and system tools).
It uses Podman by default, but can fall back to or be forced to use Docker.
Basic Usage
To run any command inside the dev container, prefix it with tools/dev_container:
tools/dev_container <command>Common Examples:
- Run cargo check:
bash tools/dev_container cargo check - Run presubmit checks:
bash tools/dev_container ./tools/presubmit quick - Run formatting:
bash tools/dev_container ./tools/fmt
Key Options
--use-docker: Force the script to use Docker instead of Podman.--pull: Pull the latest version of the container image from the registry before running the command.--stop: Stop the currently running container instance.--clean: Clean the container state (useful if the container gets into a bad state).--no-interactive: Run in non-interactive mode (useful for scripts or CI).
