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

No annotations are provided, so the description carries the full behavioral burden. 'List' implies a safe read-only enumeration, but the description says nothing about pagination, result limits, ordering, or whether an API key is needed for Adobe/Magento data. For a simple read tool this is passable but thin.

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?

Two tight sentences with the core purpose front-loaded and the usage hint immediately after. No redundant padding, though the second sentence partially restates the filters already implied by the first.

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?

For a two-optional-parameter, read-only list tool with no output schema and no annotations, the description covers purpose and use context adequately. The main omission is the plural-vs-singular distinction from get_security_bulletin and any note about result volume or pagination.

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%, so both 'since' and 'severity' are fully documented in the schema, including the YYYY-MM-DD format and the enum values. The description only restates the filter semantics at a high level, adding no format or default detail beyond the schema, so baseline 3 applies.

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 and resource ('List Adobe/Magento security bulletins (CVEs)') and clarifies the optional filters. It does not, however, distinguish itself from the singular sibling get_security_bulletin, which an agent could easily confuse with this bulk-listing tool.

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 second sentence gives two concrete usage scenarios ('list critical bulletins since a given date', 'survey what has been disclosed'), which maps cleanly onto the two optional parameters. It stops short of naming an alternative tool or stating when NOT to use it, so it lacks explicit exclusion guidance.

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