click_command

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

With no annotations, the description carries the full load and does so well: it discloses that it opens the form, replays the genuine setup from 'capture', sends a re-targeted click, and that a click yields no value read-back so verification must go through a side-effect field or a screenshot. That is meaningful behavioral context for a mutation-style action.

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 front-loaded with the action and stays to two dense sentences with no filler. The parenthetical hex and path references add precision but make it slightly hard to parse on first read.

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 mutation action with no annotations, the description covers what happens, what is mutated, how the click is sourced, and how to verify the outcome, plus it names the return shape (aligned with the existing output schema). An agent has enough to call it correctly; only explicit when-to-use routing is absent.

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 0% across 5 parameters, so the description must compensate. It explains capture (the genuine setup that clicked base_button), base_button, and target_button (defaults to base_button) reasonably, but host and port are left entirely to the schema defaults with no semantics given.

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 gives a specific verb and resource ('Click a form-command BUTTON natively') and names its functional relatives (switch_page, toggle_checkbox), which lets an agent distinguish it from those siblings. It stops short of a crisp one-line purpose because the mechanism detail (the hex command, Group/Button path) crowds the opening.

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?

By calling itself the 'Button twin of switch_page / toggle_checkbox' it implies the selection rule (use this for command buttons, those for pages/checkboxes), but it never states explicitly when to choose it or when not to. The usage signal is inferable rather than stated.

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