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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: no execution environment, no working directory, no side-effect or safety profile, no permission or sandbox constraints for what is effectively arbitrary command execution.

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?

It is short and front-loaded, but brevity here is under-specification rather than conciseness — the one sentence conveys almost no actionable information about a command-execution tool.

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 an arbitrary command runner with no annotations, no output schema, and an opaque single parameter, the description omits everything an agent needs: invocation format, execution context, and expected results. It is completely inadequate for the tool's complexity.

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 single parameter 'detail' is technically documented in the schema, which sets the baseline at 3. However, the description adds no meaning beyond the schema's generic 'Specific parameters for this action', leaving the expected command syntax unclear.

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 restates the tool name ('zsh') and adds only the generic label 'Terminal command (runner operator)', which does not specify what command is run, how the argument is interpreted, or what distinguishes zsh from a shell invocation. An agent learns nothing beyond the name itself.

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?

No guidance on when to use this versus the near-identical siblings bash and sh, nor when not to use it (e.g., against converse). The choice among four overlapping terminal/chat tools is left entirely to guesswork.

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