ssh_run_script

Execute shell scripts on remote servers over SSH for deployment tasks, piping content directly to bash without local temp files.

Instructions

SSH into a remote host and execute a multi-line shell script. The script content is piped to bash remotely; no temporary files are created locally.

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden. It discloses the method (piping to bash) and lack of local temp files, but omits details on output handling, error behavior, or authentication requirements beyond the parameters.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with the core action. No superfluous information; every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 9 parameters and no output schema, the description is adequate but not complete. It covers the core behavior but lacks details on return values, error handling, or authentication context, which could aid an agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with clear descriptions for all 9 parameters. The description adds no extra meaning beyond the schema, meeting the baseline without improvement.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (SSH and execute) and the resource (multi-line shell script). The mention of piping to bash and no temporary files distinguishes it from sibling tools like ssh_run_command, which likely runs single commands.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for multi-line scripts but does not explicitly state when to use this tool over siblings. No 'when not to use' or alternative tool names are given, leaving the agent to infer from the context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
