What it does

Shell Choice Guide is an agent skill from Jinze-Lee/codex-skills-workbench. Choose between PowerShell and Git Bash using the bundled note. Use this skill only when the user explicitly invokes $shell-choice-guide. Do not auto-select this skill for general shell, Git, PowerShell, or Bash tasks.

Its SKILL.md is about 280 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `agents/openai.yaml` and `references/source-note.md`).

It sits in Data & Analytics. It works with Git, Bash and PowerShell.

When your agent uses it

  • Explicitly invokes $shell-choice-guide

Example prompts

  • “/shell-choice-guide”

Workflow steps

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

  1. Read references/source-note.md first.
  2. Follow the note's shell-selection rules, examples, and cautions closely.
  3. Adapt paths, commands, and environment details to the current machine instead of copying historical examples blindly.
  4. Preserve the original intent of the guide while updating stale environment details.
  5. If the note conflicts with the current user request, follow the current request and explain the adjustment.

What it can do on your machine

Read from SKILL.md and the folder at commit 7aa34a5. 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.

    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

Shell Choice Guide loads about 281 tokens when it runs, and up to ~701 if it reads all its reference files. Until then it costs about 60 tokens; SKILL.md has 106 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~281
With references · SKILL.md plus every file in references/, read only if the agent opens them
~701

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 106 words (~281 tokens).
