sap_press

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

With no annotations, the description carries the full behavioral burden, and it discloses almost nothing: pressing a GUI button can trigger screen changes, dialogs, or committed transactions, but none of that is mentioned. There is no note on permissions, error behavior, or whether a screenshot/refresh is needed afterward.

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 well-formed sentence with no filler and the action front-loaded. It is efficient, though borderline under-specified rather than genuinely concise.

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 one-parameter automation tool with no annotations and no output schema, the description omits the two things an agent most needs: what element_id refers to and how it differs from sap_click. The overlap with other interaction siblings is left unresolved.

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% for the single required 'element_id' parameter (minLength 6, maxLength 1024). The description does not explain what an element_id is, where to obtain it (e.g., from sap_get_screen), or what format it takes, so the parameter is effectively undocumented.

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 ('Press') and resource ('SAP GUI button') plus the mechanism ('through its COM interface'), which is enough to identify the action. However it does not distinguish itself from the sibling tool sap_click, which appears to serve an overlapping purpose, leaving the agent to guess which to use.

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 gives no guidance on when to prefer this over sap_click, sap_send_vkey, or sap_run_guixt_script. There are no prerequisites, no mention of requiring an active transaction, and no stated conditions under which pressing is appropriate.

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