get_email_client_settings

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

No annotations are supplied, so the description carries the full burden. The verb 'Get' signals a read-only operation and the parenthetical discloses the shape of the returned settings, but auth requirements, whether settings differ per domain, and error behavior for unknown accounts are unstated.

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?

One front-loaded sentence with a compact parenthetical list; no filler. It is arguably thin rather than bloated, so the brevity is efficient rather than wasteful.

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 single-parameter read tool with no output schema, the description covers purpose and roughly what comes back (ports, hostnames, SSL settings). Missing only guidance on the manual vs auto-config distinction and failure cases.

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 coverage is 100% and the single 'account' parameter is documented as an email address with an example, so the schema does the work. The description adds no further meaning about the parameter (e.g. that it must be an existing account on this server).

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?

Specific verb 'Get' plus a precise resource ('mail client manual and auto-config settings') and an enumeration of the returned fields (IMAP, POP3, SMTP ports, hostnames, SSL). It is clearly distinct from siblings like get_email_routing or get_email_disk_usage, though it never names an alternative explicitly.

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?

Usage is only implied: an agent can infer this is for retrieving client configuration when setting up a mail client. There is no statement of when to prefer it, no prerequisites, and no mention of related tools such as list_email_accounts.

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