Type text

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

Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false and destructiveHint=false, so safety is covered. The description adds real behavioral detail beyond that: text lands in whatever element currently has focus when 'target' is omitted, and 'press_enter' fires an Enter keystroke afterwards as a side effect. It does not say what happens when the label matches nothing or multiple fields.

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?

Three short sentences with zero filler, front-loaded with the primary action before the targeting and keystroke options. The example labels ('Site title', 'Page title') are compact and directly useful.

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 simple four-parameter input tool with no output schema, the definition covers the action, the focus model and the Enter side effect. The remaining gap is failure behavior when 'target' does not resolve, plus no hint about what the tool returns on success.

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 coverage is 75%, so the baseline sits at 3. The description usefully explains the semantics of 'target' (placeholder or aria-label, with examples) and covers 'press_enter', which the schema leaves undocumented, but it never mentions 'clear_first' and its select-all-then-replace behavior, leaving that parameter to the schema alone.

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 and resource (type text into the currently focused field/box) and adds the key distinguishing detail that it can first focus a field by label. That focus-based framing separates it from siblings like gsites_add_text or gsites_set_page_title, which create content rather than drive an existing input.

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?

Gives explicit operational guidance: supply 'target' to focus a field first, or omit it to type into whatever is already focused. It does not name alternative siblings (e.g. gsites_click followed by typing, or gsites_set_page_title for title fields) or state when this tool should not be used, so it stops short of full alternative routing.

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