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

No annotations are supplied, so the description carries the full burden; 'Get' makes the read-only, no-side-effect nature evident and it compensates for the absent output schema by explaining the semantics of security.fixedBy and security.vulnerableTo. It stops at 4 because it says nothing about lookup failures (unknown version/distribution), rate limits, or authentication, which an agent may need when a version is not found.

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?

One front-loaded sentence that opens with the verb and resource before unpacking the return fields. The inline parenthetical glosses on the two security fields are dense but each earns its place; no filler sentences.

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, the description must (and does) explain the payload, naming the key sections and disambiguating the two security sub-fields. Error/not-found behavior is the only meaningful omission for a two-required-parameter lookup 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 description coverage is 100%: both parameters are documented, with an example version format ('2.4.8', '2.4.7-p3') and an enum for distribution. The description adds no format or constraint detail beyond that, so the baseline 3 is correct.

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?

Clear verb+resource: 'Get detailed information about a specific Magento/Adobe Commerce version', with the returned field set enumerated (release date, EOL, system requirements, security summary). The word 'specific' implicitly separates it from get_all_versions / get_latest_version, but no sibling is named explicitly, so it stops short of a 5.

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 is purely declarative — it never says when to call this versus check_version_security, get_security_bulletin, or get_all_versions, even though the security summary overlaps heavily with the security-check siblings. No prerequisites, no exclusions, no routing hint.

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