Bash add alias jobs for your Linux shell, reviewed as diffs

What the agent can use

• Filesread_file, edit_file, copy_file, grep and glob work inside the chat's working folder, and edit_file shows each change as a diff that you accept or reject.
• Shellruns a command in local Windows, in WSL, or over SSH on your own server, reports the real exit code, and blocks dangerous commands.
• Webweb_search looks things up and http_get reads one documentation page, for example the manual for a bash built-in.
• Screenshots and imagesocr reads text from a saved screenshot, such as an error message in a terminal window, and gen_image saves image files.
• Orchestrationtask starts parallel sub-agents, run_on_model sends a hard step to a bigger model, and skills are reusable playbooks for jobs you repeat.
• Approval modesAuto-run acts at once, Ask first pauses before actions that change something, and Plan only writes a plan and runs nothing.
• Cronruns a prompt on a schedule, for example a recurring check that your ~/.bashrc still loads and that Shell returns a successful exit code.
• Modelsconnect a cloud AI provider, a model running on your PC, or the built-in model, which is ready to use without your own endpoint.

Common tasks

Add a shortcut to a folder

Task: jump to a project folder with one short word. The agent reads your aliases file with read_file, copies it with copy_file, and proposes a single line with edit_file, for example a name that runs cd into your projects folder. A bashrc scriptlet can switch the cd directory for you in the same way, and the diff shows it as a few added lines. Shell then loads the file with source and reports the exit code. Short list. Ask first pauses before the write, so you read the diff, accept it, and test the new name in a fresh terminal. The same pattern works for any shortcut: the agent names the tools it uses, you see each result, and no file changes before you approve it.

Add alias linux entries in bulk

Task: put several related shortcuts in one place. To add alias linux entries for ll, la and a disk summary, the agent reads ~/.bash_aliases with read_file, searches for name clashes with grep, and proposes the full block as one diff. Per-directory shell history is a separate topic, and the agent can draft those bashrc lines too if you ask. It tells you which lines are new. Plan only writes the plan and runs nothing, so you can read all 3 additions first, then switch to Ask first, accept the diff, and run alias to see the list. The agent shows the final alias list in the card, so nothing about the result is hidden from you. Because the agent reads before it writes, it can notice that a name is already taken and tell you before proposing a clash.

Change the prompt colors

Task: make the prompt calmer. Many users want to remove prompt color after copying a colorful line from a forum, and the agent finds the line that sets the prompt in ~/.bashrc with grep and reads it with read_file. edit_file proposes a shorter version as a diff, so you see which escape codes disappear. Shell cannot show the colors for you, because the check is how the prompt looks, which is your job. Take your time. Open a new terminal after accepting the diff and judge the result with your own eyes. This is also how you try a new line safely: you load it, look at the result, and ask for a revert if it is not what you wanted.

Back up before you edit

Task: protect the file you rely on every day. The agent uses copy_file to save ~/.bashrc under a new name in the same folder, then read_file to confirm the copy opens, and only after that does edit_file propose the real change. You choose the backup name, and a restore is another copy_file call in the opposite direction. Two files exist. Ask first pauses before every write, so the diff, the accept click and the test in a new shell form a loop you can repeat for each of the 8 tools in the feature list. When you are finished, the backup and the new file sit side by side, which makes a later comparison straightforward and keeps your own history clear.
