type_text

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

No annotations are supplied, so the description carries the full burden, yet it discloses nothing beyond the basic action: no mention of whether a trailing newline/enter is sent, how fast text is sent, what happens if the VM is stopped or unfocused, or whether characters outside the keyboard layout are dropped. For an input-injection tool this is a substantial gap.

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?

A single short sentence with the action front-loaded and no filler. Its brevity is appropriate in form, though the small amount of text is also the source of the definition's gaps.

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?

An output schema exists, so return values need not be explained, but with zero annotation coverage and 0% schema description coverage the description should say more about focus/running-state requirements and typing semantics (newline handling, special characters) than it does.

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 0% and the fields carry only titles, so the description must compensate. It does minimally: 'text' is clarified as the string typed as key input, and 'vm_name' as the lume VM targeted, which is slightly more than the bare property names.

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?

States a specific verb ('type') and resource ('string as keyboard input') and names the target ('specified lume VM'), which separates it from click, key_press and screenshot by the nature of the operation. It does not, however, explicitly contrast itself with the closest sibling key_press.

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 choose this over key_press (single key) or click, and no stated prerequisites such as the VM being running or the target window having focus. The agent must infer the selection rule from the verb alone.

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