About the using-string skill
Interacting with String applications, web pages, and shell sessions through a command-based interface allows developers to automate complex workflows across different environments. An agent should load this skill when it needs to manage installed applications, execute bash commands, or configure system variables. The tool operates using a specific topic and command structure, requiring inputs like topic and cmd to function.
Users can navigate through various topics such as main, app, bash, or system to target specific contexts. The skill provides commands like /open to access files and URLs, /install to add new applications, and /set to manage credentials via variable assignments. When the tool returns a payload, it uses a specific XML-style tag format, and agents must follow recovery or next hints provided within that text to continue the task. This approach provides a unified way to control diverse tools like SFMD and shell sessions through a single interface.
What an agent can do with it
- 1Manage application configurationsConfigure application credentials by setting specific environment variables.
- 2Execute shell commandsRun commands within a specific bash session topic.
- 3Access external web contentOpen and read information from specific URLs.
- 4Install new software toolsAdd new applications to the existing environment.

View on GitHubUsing String
You have the installed String MCP tool named string; some hosts display it with a server prefix.
Call it with { topic, cmd }, for example { "topic": "main", "cmd": "/info" }.
Use topics like main, app:<name>, app:<name>:<config>, bash:<name>, or hubs app, tool, bash, system.
cmd must start with /; use /help, /info, and /act --help to discover what to do.
Use /open to read files, URLs, or apps; installed apps can run /act.<name> directly from app:<name> if you already know the action.
Use /install to add apps; /set $VAR = "..." for app credentials.
Read the payload inside <𝒞=string:TOPIC>...</𝒞> and follow Recovery: or next: hints.
