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

Without annotations, the description carries full burden. It mentions 'heuristic' suggesting imprecision but does not elaborate on the algorithm (e.g., sample generation vs. exact intersection check). The role of the 'samples' parameter is ambiguous: does the tool use those samples, or does it generate them? This lack of detail limits transparency.

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 a single sentence, which is concise, but it omits necessary details such as return type, parameter explanations, and usage context. While conciseness is valued, here it sacrifices completeness.

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 tool has 3 parameters (2 required) and no output schema, the description should explain return values, parameter formats, and edge cases (e.g., invalid ranges). It does not mention what the function returns (likely a boolean) or how the 'samples' parameter affects the heuristic check. This is incomplete for an agent to use reliably.

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 description adds no meaning beyond the schema. With 0% schema description coverage, it should explain range_a, range_b (semver range format), and samples (is it inputted sample versions or generated ones?). The description only mentions 'two semver ranges' and 'sample versions' without clarifying parameter roles or formats.

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 if two semver ranges intersect ('share any sample versions') as a conflict hint. The verb 'check' and resource 'two semver ranges' are specific, and it distinguishes from sibling semver tools like semver_satisfies (version vs range) and semver_compare (version comparison). However, it could explicitly state the output type (boolean) for full clarity.

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 no guidance on when to use this tool versus its siblings. For example, it does not mention that semver_satisfies_batch checks versions against a range, or that semver_max_satisfying finds a version. This lack of contextual guidance makes it harder for an agent to choose the correct tool.

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