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

With no annotations provided, the description carries full burden. It discloses the output format (compatible/review/incompatible with plain-English note) and a disclaimer. However, it does not explicitly state read-only nature, side effects, or other behavioral traits, which are important for an agent to understand.

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 concise and front-loaded: first sentence states purpose, second describes output, third adds uniqueness and a hint. Every sentence adds value with no wasted words.

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?

Given the simplicity of the tool (two string inputs) and the existence of an output schema, the description covers the key aspects: purpose, input semantics, output format, and a legal disclaimer. It could mention any edge cases or dependencies, but for typical use it is sufficient.

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 coverage is 100%, so baseline is 3. The description does not add meaning beyond the schema; it reiterates that inputs are SPDX IDs but does not provide additional context or constraints beyond what the schema already covers.

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 tool's function: checking SPDX license compatibility between two licenses. It specifies the return values (compatible/review/incompatible) and uses an example question to illustrate usage. The mention of being the only MCP without a separate SCA tool distinguishes it from external tools, and sibling tools don't overlap directly.

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 description provides a usage example and a disclaimer ('not legal advice'), but does not explicitly state when to use this tool vs alternatives or when not to use it. It implies it is the go-to tool for license compatibility among MCPs but lacks direct comparison with sibling tools.

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