-Executes a given bash command in a fresh shell session with optional timeout, ensuring proper handling and security measures.
-
-All commands run in ${directory} by default. Use the `workdir` parameter if you need to run a command in a different directory. AVOID using `cd <directory> && <command>` patterns - use `workdir` instead.
-
-When searching for text or files, prefer using rg or rg --files respectively because rg is much faster than alternatives like grep. (If the rg command is not found, then use alternatives.)
-
-1. Directory Verification:
-   - If the command will create new directories or files, first use `ls` to verify the parent directory exists and is the correct location
-   - For example, before running "mkdir foo/bar", first use `ls foo` to check that "foo" exists and is the intended parent directory
-
-2. Command Execution:
-   - Always quote file paths that contain spaces with double quotes (e.g., rm "path with spaces/file.txt")
-   - Examples of proper quoting:
-     - mkdir "/Users/name/My Documents" (correct)
-     - mkdir /Users/name/My Documents (incorrect - will fail)
-     - python "/path/with spaces/script.py" (correct)
-     - python /path/with spaces/script.py (incorrect - will fail)
-   - After ensuring proper quoting, execute the command.
-   - Capture the output of the command.
-
-Usage notes:
-  - The command argument is required.
-  - You can specify an optional timeout in milliseconds. If not specified, commands will time out after 120000ms (2 minutes).
-  - If the output exceeds ${maxLines} lines or ${maxBytes} bytes, it will be truncated and the full output will be written to a file. Inspect only relevant sections and prefer rg for search when available. Because of this, you do NOT need to use `head`, `tail`, or other truncation commands to limit output - just run the command directly.
+Run a shell command. All commands run in ${directory} by default. Use `workdir` to run in a different directory.
+Prefer `rg` for searching text/files. Output is truncated at ${maxLines} lines or ${maxBytes} bytes.

-Performs exact string replacements in files. 
-
-Usage:
-- The edit will FAIL if `oldString` is not found in the file with an error "oldString not found in content".
-- The edit will FAIL if `oldString` is found multiple times in the file with an error "Found multiple matches for oldString. Provide more surrounding lines in oldString to identify the correct match." Either provide a larger string with more surrounding context to make it unique or use `replaceAll` to change every instance of `oldString`. 
-- Use `replaceAll` for replacing and renaming strings across the file. This parameter is useful if you want to rename a variable for instance.
+Replace an exact string in a file. `oldString` must appear exactly once, or the edit fails. Use `replaceAll` to replace every occurrence.
