At a glance

Check a golem Shiny application for package issues. An agent skill from ThinkR-open/golem.

  • : - check my golem app - run R CMD check - validate the package Do not trigger on: - when the user is not working inside a golem app

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Golem Check App is an agent skill from ThinkR-open/golem. Check a golem Shiny application for package issues. Triggers on: - "check my golem app" - "run R CMD check" - "validate the package" Do not trigger on: - when the user is not working inside a golem app

Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: A Framework for Building Robust Shiny Apps.

When your agent uses it

  • : - check my golem app - run R CMD check - validate the package Do not trigger on: - when the user is not working inside a golem app

Example prompts

  • “check my golem app”
  • “run R CMD check”
  • “validate the package”
  • “/golem-check-app”

What it can do on your machine

Read from SKILL.md and the folder at commit fed0c3c. 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 r).

    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

Golem Check App loads about 391 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 150 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~391

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 150 words (~391 tokens).

“You are helping a user check their golem Shiny application for errors and warnings.”
