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

No annotations are supplied, so the description carries the full behavioral burden, and it does disclose one important state effect: responses stay unmatched until the choice is made. It says nothing about reversibility (can a choice be changed later), whether previously matched responses are re-attributed, what permissions are needed, or what the tool returns on success or on a linkId that does not open the form.

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?

Two compact sentences with no filler, and the conflict condition plus the un-matched consequence are front-loaded. The parenthetical reference to google_forms_detected_list is slightly dense but earns its place by anchoring the trigger.

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 two-parameter mapping tool with no output schema and no annotations, the description covers purpose, trigger, and the consequence of inaction well enough to invoke it correctly. The remaining gaps — reversibility of a choice and handling of already-matched responses — are secondary but not trivial for a configuration mutation.

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 both formId and linkId are already documented, including the constraint that the link must open that form. The description adds no syntax, format, or selection detail beyond what the schema states, so the baseline of 3 applies.

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 names a specific action (choosing which link a form's responses belong to) and a concrete object (a Google Form behind several links), so it is distinguishable from siblings such as google_forms_detected_list and google_forms_sync. It stops short of 5 because the phrasing 'choose which link ... responses belong to' describes the outcome rather than the concrete change being made to the form-link mapping.

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?

It clearly states the triggering condition — the same form appearing behind several links as a conflict surfaced in google_forms_detected_list — and adds a consequence ('Until then that form's responses are not matched') that tells the agent why to act. There is no explicit when-not guidance, no mention of whether the tool is needed per-conflict, and no alternative resolution path named.

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