shellcheck-configurationShellCheck Configuration is a skill in wshobson/agents (40k stars). Its SKILL.md is about 403 tokens, with 1 other file in the folder (references), and copies of it appear in 11 other owners' repositories. Licence: MIT.
8 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 46891e7. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
ShellCheck Configuration loads about 403 tokens when it runs, and up to ~2.4k if it reads all its reference files. Until then it costs about 51 tokens; SKILL.md has 177 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.
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.

Run `npx skills add wshobson/agents --skill shellcheck-configuration -a claude-code`. Or copy the skill folder (plugins/shell-scripting/skills/shellcheck-configuration in wshobson/agents) into .claude/skills/shellcheck-configuration in your project. Claude Code loads it when a task matches its description.
Run `npx skills add wshobson/agents --skill shellcheck-configuration -a codex`. Or copy the skill folder (plugins/shell-scripting/skills/shellcheck-configuration in wshobson/agents) into .agents/skills/shellcheck-configuration in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add wshobson/agents --skill shellcheck-configuration -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/shellcheck-configuration, .gemini/skills/shellcheck-configuration, .github/skills/shellcheck-configuration and .opencode/skills/shellcheck-configuration in your project.
SKILL.md names no scripts, command-line tools or credentials: ShellCheck Configuration is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
ShellCheck Configuration is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 403 tokens (SKILL.md is roughly 1.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with ShellCheck Configuration: Golang Continuous Integration (samber/cc-skills-golang, 3.4k stars), Golang Continuous Integration (context-labs/whip, 1.1k stars), Bash Pro (promovaweb/setupvibe, 101 stars) and Writing Bash Scripts (archibate/dotfiles-opencode, 108 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
