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

With no annotations, the description carries the full burden and does substantive work: it discloses the return shape (securitySummary { status, requiredPatches, upgradeRequired }) and, crucially, warns that isSecureVersion/statusLabel reflect lifecycle only so a supported version may still have open bulletins. It omits auth/rate-limit/pagination behavior, but the field-semantics caveat is real added value.

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?

Three compact sentences, front-loaded with the core action, then the return-shape caveat, then the sibling pointer. Dense with braces/field names but every sentence earns its place; no padding.

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?

No output schema and no annotations, yet the description covers the key return fields and their interpretation caveat, and routes to check_version_security for remedies. Adequate for a simple read tool, though it doesn't clarify its relationship to the other version-listing siblings.

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 single 'distribution' parameter has 0% schema description coverage, but its enum values (magento-community, magento-commerce, mage-os) are self-explanatory. The description only says 'for a distribution' and adds no meaning beyond the schema, so this is a baseline 3.

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+resource ('Get all versions for a distribution') plus the payload characteristic ('with their lifecycle information'). The scope 'all versions' implicitly differentiates it from get_latest_version, get_supported_versions, and get_eol_versions, but it never names those siblings, so differentiation is left partly to inference.

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?

Provides clear context (fetch every version's lifecycle/security summary) and an explicit routing instruction: 'Call check_version_security for the remedies.' It does not, however, state when NOT to use this tool or how it relates to the heavily overlapping get_supported_versions / get_eol_versions siblings.

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