execute_command

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

No annotations are provided, so the description must carry the full burden of disclosure. It does not mention that command execution can be destructive, require permissions, or produce side effects. The only behavioral detail (remote/local) is already evident from the schema.

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

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

The description is short, but the parenthetical 'This tool can be used for both remote hosts and the current machine' repeats the first clause. This redundancy is somewhat inefficient.

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

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

For a command execution tool with no output schema and no annotations, the description is severely lacking. It does not explain return values, error handling, or the potential for system-altering effects, which is essential for a tool of this power.

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

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

Schema description coverage is 100%, so the baseline is 3. The tool description adds no parameter-level detail, but the schema descriptions for command, host, and env are clear and include relevant context like checking system type.

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

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

The description clearly states it executes commands on remote hosts or locally, which is a specific verb+resource combination. There are no sibling tools to differentiate from, so the clarity is sufficient.

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

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

The description mentions it works for remote and local hosts, but provides no guidance on when to use this tool versus alternatives or when not to use it. No exclusions or preconditions are given.

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