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

No annotations are provided, so the description carries the full burden. It states the core input-output behavior but does not disclose behavior for invalid or unknown IDs, case sensitivity, or what happens when q is empty. These are meaningful gaps for a tool with no annotation safety profile.

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?

The description is very short and front-loaded, containing the key mapping in a single sentence. It would earn a 5 if not for the redundant 'SPDX License:' prefix that partly repeats the tool title.

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 simple one-parameter lookup tool with an output schema, the description covers the essential input meaning. However, it does not clarify optionality of q, expected values, or edge-case behavior, so the agent must make assumptions when constructing valid calls.

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?

The schema has one undocumented parameter 'q' with 0% description coverage. The description adds the crucial meaning that q should be an SPDX license ID, but it omits examples or format details, leaving the agent to infer standards like 'MIT' or 'Apache-2.0'.

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 clearly states the resource (SPDX licenses) and the transformation (license id → name + OSI status). It is specific enough for an agent to understand the tool's function, though it lacks an explicit verb like 'lookup' and does not explicitly differentiate from other sibling tools.

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 intended use case is implied: when an agent has an SPDX license ID and needs its canonical name and OSI status. However, there is no explicit guidance about when not to use it or mention of relevant alternatives.

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