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

Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so safety is covered externally; the description contributes no additional behavioral context. It does not say what happens when all filters are omitted (all meetings returned?), how results are ordered, or how large the result set can be — relevant because zero parameters are required.

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 front-loaded sentence with no filler, which is appropriate for a simple list endpoint. It is terse rather than padded, though the terseness edges toward under-specification rather than elegant brevity.

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 four-parameter, fully-documented read-only list tool with no output schema, the description is minimally viable: the schema carries parameter detail and annotations carry the safety profile. What is missing is disambiguation from the many sibling list/get tools and any note on unfiltered result behavior, which an agent needs to call this correctly.

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 each parameter (group, since, until, state) is already documented with format and semantics. The description's 'by group and date' only echoes two of the four filters and omits state entirely, so it adds nothing beyond the schema. 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 3GPP working group meetings') and scopes it to group and date, which distinguishes it from the singular sibling get_meeting. It does not, however, acknowledge list_meeting_decisions or clarify how it differs from the other list_* tools in the family.

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?

There is no when-to-use guidance and no alternatives named. An agent cannot tell from the description whether to call this or get_meeting for a single meeting, or how this relates to list_meeting_decisions. Usage is only implied by the verb 'List'.

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