panelica_accounts_get_v1_accounts_id_emails

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, and the description adds the non-obvious auth requirement 'Required scopes: accounts:read'. That is useful disclosure beyond the structured annotations, though it does not mention pagination, result size, or what the returned list contains.

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?

The description is compact and front-loaded with the action, followed by endpoint, category, scope, and read-only flag in a clearly separated block. Every line carries distinct information and there is no filler or redundant expansion.

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 one-parameter read-only endpoint this is mostly adequate, but with no output schema and a sibling that lists email accounts, the description leaves ambiguity about what 'emails' means and does not define the return shape. It is a minimum-viable description rather than a fully self-sufficient one.

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%, and the only parameter is 'id', described as 'Path parameter: id'. The tool description adds no further meaning to the parameter, so the baseline score of 3 applies because the schema already documents it adequately.

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?

The description opens with 'List emails', a clear verb and resource, and the HTTP path 'GET /v1/accounts/:id/emails' anchors it to a per-account email listing. It does not fully explain what counts as an 'email' here (addresses vs. messages) or explicitly distinguish itself from sibling endpoints like panelica_email_get_v1_email_accounts_id, so it stops short of perfect clarity.

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 statement of when to use this tool versus alternatives; the only contextual clues are the path and category. Required scopes and read-only markings describe access requirements, not decision rules, and no alternative sibling is named.

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