A4.3/5.0
Behavior3/5

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

With no annotations provided, the description carries the burden of disclosing side effects, but it does not explicitly state whether the tool is read-only or whether it has any permissions or side effects. The content strongly implies a safe schema-inspection operation, but explicit transparency is absent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, focused sentence that lists the exact outputs and the recommended usage. There is no redundant or irrelevant information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Since there is no output schema, the description adequately explains the expected return contents: columns, numeric flags, row count, and provenance banner. It also provides the broader context of learning the schema, making the tool's role clear.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, so there are no parameter semantics to explain. The description focuses on what the tool returns, which is appropriate given the empty input schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool returns the columns, numeric flags, row count, and provenance banner for the HostingByStack dataset. It also explicitly frames the tool as the first step to learn the schema, making its purpose unmistakable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives direct usage guidance by saying 'Call this first to learn the schema,' which tells the agent when to use this tool in a workflow. It does not explicitly contrast it with sibling tools, but the 'first' instruction provides clear placement.

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

A3.8/5.0
Disambiguation4/5

The dataset_* tools are mostly distinct, but dataset_row and dataset_compare overlap: both retrieve rows by matching a column value, and compare can effectively do row's job with a single value. The enquiry_* tools are clearly separated by behavior, fields, and submission.

Naming Consistency4/5

Tool names consistently use lowercase snake_case with clear domain prefixes: dataset_* and enquiry_*. However, some names are nouns (dataset_columns, dataset_row, dataset_stats) while others are verbs or adjectives (dataset_compare, dataset_search, dataset_top), so the pattern is not perfectly uniform.

Tool Count5/5

Ten tools is well-scoped for a server covering two clear areas: read-only dataset exploration and enquiry submission. Each tool has a practical role, and the count is comfortably within the ideal range.

Completeness4/5

The dataset side covers schema, provenance, exact lookup, substring search, comparisons, statistics, and top/bottom rows, which is strong for a read-only dataset server. The enquiry side covers describing the process, listing fields, and submitting with a two-step confirmation, though there is no way to check submission status or cancel an enquiry.
