What it does

Skillshare Devcontainer is an agent skill from JetBrains/skills, published by the product's own GitHub organization. Run CLI commands, tests, and debugging inside the skillshare devcontainer. Use this skill whenever you need to: execute skillshare CLI commands for verification, run Go tests (unit or integration), reproduce bugs, test new features, start the web UI, or perform any operation that requires a Linux environment. All CLI execution MUST happen inside the devcontainer — never run skillshare commands on the host. If you are about to use Bash to run ss, skillshare, go test, or make test, stop and use this skill first to…

Its SKILL.md is about 2k 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 Frontend & Design, covering Frontend development. It works with Linux, Bash, Docker and Git. The repository describes itself as: Curated agent skills collection verified by JetBrains.

When your agent uses it

  • You need to: execute skillshare CLI commands for verification
  • Run Go tests (unit
  • Test new features
  • Start the web UI

Example prompts

  • “/skillshare-devcontainer”

Requirements

  • Docker

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Edit files on host (Read/Edit tools)
  2. docker exec $CONTAINER ss — picks up your changes instantly
  3. No make build, no restart, no rebuild step

What it can do on your machine

Read from SKILL.md and the folder at commit e0f258b. 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:

    • docker
    • make
    • go
    • bash

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use docker, 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

Skillshare Devcontainer loads about 2k tokens when it runs. Until then it costs about 146 tokens; SKILL.md has 690 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~146
When it runs · the whole SKILL.md, loaded when a task matches
~2k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 690 words (~2,032 tokens).

“Execute CLI commands and tests inside the devcontainer. The host machine is macOS but the project binary is Linux — running CLI commands on the host will silently produce wrong results or fail. This skill prevents that mistake.”
