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

With no annotations, the description must carry the full behavioral disclosure burden. It implies read-only listing, but it does not mention pagination behavior, owner-email/auth constraints, rate limits, ordering, or whether results are date-rounded.

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 concise, front-loaded sentence with no filler words. It is efficient, though the description could be expanded with structured usage and behavior details without becoming bloated.

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 tool with no annotations, no output schema, and low parameter coverage, this description is too abbreviated. It omits when to use the tool, expected return shape, pagination semantics, and auth caveats, leaving an agent reliant on schema inference.

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 only 33%; only owner_email has a description. The description does not explain limit or offset and does not compensate for the schema's gaps, so an agent gets little parameter-level guidance beyond the defaults.

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 clear verb and resource: 'List past outbound call records.' The qualifiers 'past' and 'outbound' distinguish this from call-making siblings such as makeInstantCall and quickCall, though it does not explicitly name any alternative log/list 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?

No guidance is provided on when to use this tool versus siblings or when not to use it. The only content is a one-line purpose statement; there are no prerequisites, exclusions, or alternative tool mentions.

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