26/// Executes a shell one-liner and returns the combined output.
27///
28/// This tool spawns a process using the user's shell, reads from stdout and stderr (preserving the order of writes), and returns a string with the combined output result.
29///
30/// The output results will be shown to the user already, only list it again if necessary, avoid being redundant.
31///
32/// Make sure you use the `cd` parameter to navigate to one of the root directories of the project. NEVER do it as part of the `command` itself, otherwise it will error.
33///
34/// Do not generate terminal commands that use shell substitutions or interpolations such as `$VAR`, `${VAR}`, `$(...)`, backticks, `$((...))`, `<(...)`, or `>(...)`. Resolve those values yourself before calling this tool, or ask the user for the literal value to use.
35///
36/// Do not pipe output to `head`, `tail`, or similar output-filtering commands just to reduce what you receive. Instead, use `head_lines` and/or `tail_lines`; this keeps the terminal output visible to the user in real time while limiting only the final output sent back to you. When both are specified, the first `head_lines` lines are returned, then a blank line, then the last `tail_lines` lines. Avoid requesting too many lines, or the response may waste tokens or exceed the context window.
37///
38/// Do not use this tool for commands that run indefinitely, such as servers (like `npm run start`, `npm run dev`, `python -m http.server`, etc) or file watchers that don't terminate on their own.
39///
40/// For potentially long-running commands, prefer specifying `timeout_ms` to bound runtime and prevent indefinite hangs.
41///
42/// Remember that each invocation of this tool will spawn a new shell process, so you can't rely on any state from previous invocations.
43///
44/// The terminal is an interactive pty, so any command that blocks waiting for input will hang the tool until it times out. To avoid this:
45///
46/// - Always insert `--no-pager` immediately after `git` for any read-only git command, including `git log`, `git diff`, `git show`, `git blame`, and `git stash show`. Example: `git --no-pager log -n 5` (NOT `git log -n 5`).
47/// - Prefer Git flags that avoid optional metadata writes when possible, such as `git --no-optional-locks status` instead of `git status`.
48/// - Always prepend `GIT_EDITOR=true ` to any git command that may invoke an editor, including `git rebase`, `git commit`, `git merge`, and `git tag`. Example: `GIT_EDITOR=true git rebase origin/main` (NOT `git rebase origin/main`).
49/// - For other commands that may open a pager or editor, set `PAGER=cat` and/or `EDITOR=true` similarly.
