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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the description's only added behavioral fact is that the assessment is free. It does not say whether a call returns questions, a score, or a link, or whether it must be called before the sibling tools.

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 front-loaded sentence with no padding, which is good, but the space is spent on marketing adjectives and a mismatched product name rather than on information that changes how the tool is called.

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?

With no output schema, no annotation explanation of results, and an undocumented parameter, an agent still cannot predict what this call produces or how its result feeds the sibling tools. The description should at minimum say what is returned and whether it is a prerequisite step.

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?

There is one parameter ('context') with 0% schema description coverage, and the description says nothing about it — no hint whether it is a conversation context blob, a user identifier, or optional framing text. Since the param count is not zero, the baseline-4 rule for zero-param tools does not apply.

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 states a specific verb ('Get') and resource ('assessment') and enumerates the domains it covers (attachment, communication, conflict, strengths), which is useful. However, it names the assessment 'Figlet' while the tool name and title say 'Empathi Relationship Assessment', leaving an agent unsure which product this actually returns.

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?

There is no statement of when to use this tool versus the clearly related siblings (ask_relationship_expert, find_couples_therapist, repair_right_now, wisdom_score_preview). The single clue is the word 'free', which implies an entry-point/lead-gen tool but is never framed as a selection rule.

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