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 what is compared but not whether the result is a boolean, a constraints table, or an error when the version is unknown, and it says nothing about read-only nature, data source, or failure modes.

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?

A single efficient sentence with no filler, and the target resource is front-loaded. It is terse to the point of under-specification, but nothing is wasted.

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?

With no output schema and no annotations, the description should indicate what a compatibility check returns (status, constraints, or error) and how the four required inputs interact. None of that is present, leaving the agent with a name-only understanding of a fully-required four-parameter tool.

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 75%, so most parameters are already documented. The description adds that 'dependency' spans PHP, MySQL, and other packages, mildly reinforcing the schema example, but the enum 'distribution' parameter is never explained in the description and the dependency/magentoVersion pairing is only implied.

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 ('Check ... compatible') and names both resources: a dependency version and a Magento version. This distinguishes it from siblings like check_version_security (security) and get_supported_versions (enumeration), though it never names an alternative 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 when-to-use guidance, prerequisites, or comparison to siblings. The agent must infer from the name alone that this is for version-compatibility questions rather than security or EOL lookups, which sibling tools cover.

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