Spss Cluster Hierarchical

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

With no annotations, the description carries the full burden. It usefully discloses the external dependency ('Requires IBM SPSS Statistics to be installed'), but says nothing about whether this executes syntax that mutates the session, what permissions are needed, or how execution failures surface.

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, front-loaded with the core action. Efficient, though the dependency note could be positioned after the capability details for better priority ordering.

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?

An output schema exists, so return-value explanation is not required. For a fairly complex 6-parameter statistical tool with zero schema documentation, however, the description leaves method/measure selection and variable input expectations unexplained.

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 6 parameters. The description gestures at 'multiple linkage methods and distance measures' (method, measure) and the dendrogram flag, but adds no enum semantics, no explanation of file_path/variables/id_variable, and no indication of defaults or required fields.

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+resource: 'Run hierarchical cluster analysis with dendrogram.' This clearly identifies the statistical procedure and distinguishes it from siblings like spss_twostep_cluster and spss_factor, though it never names the differentiating sibling explicitly.

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?

No guidance on when to choose hierarchical clustering over spss_twostep_cluster, nor prerequisites such as variable type requirements or when linkage/distance choices should be varied. The reader must infer usage entirely.

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