What it does
Bash Scripting is an agent skill from ChrisTitusTech/titus-ai. Create, review, and debug Bash or POSIX sh scripts when portability, quoting, failure handling, or shell-specific validation matters.
Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Development, covering Shell scripting. It works with Bash.
When your agent uses it
- Tasks that involve Shell scripting
Example prompts
- “/bash-scripting”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Inspect repository instructions, the target shell, callers, and supported platforms.
- Decide whether the script requires Bash or should remain POSIX sh.
- Identify inputs, side effects, privilege needs, failure behavior, and cleanup.
- Implement the smallest maintainable change using existing project helpers.
- Validate syntax, static analysis, formatting, and representative success and failure paths.
What it can do on your machine
Read from SKILL.md and the folder at commit 162d624. 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:
bashshshellcheck
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
Bash Scripting loads about 737 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 341 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 341 words (~737 tokens).
“Run only the interpreter-specific checks that match the declared shell.”

Can I use Bash Scripting in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ChrisTitusTech/titus-ai --skill bash-scripting -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/bash-scripting, .gemini/skills/bash-scripting, .github/skills/bash-scripting and .opencode/skills/bash-scripting in your project.
