notify_status

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

With no annotations supplied, the description carries the full behavioral burden, and it does disclose the key trait ('Read-only') plus what data is surfaced. However, it never says whether the call performs a live SMTP connection check or merely reports cached config/log state, and it says nothing about failure modes or return shape beyond a loose enumeration. Useful but incomplete for a no-annotation tool.

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?

It is a single sentence that leads with the most load-bearing fact ('Read-only') and then enumerates returns in parentheses. The parenthetical lists are dense but every clause adds information; no filler or restatement of the name.

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?

With no output schema and no annotations, the description must carry the return-value burden, and it does enumerate the expected fields (SMTP settings, login yes/no, recipients, last send, recent failures, one-line problem). It is missing only the distinction between live probing and static reporting, which is a meaningful but singular gap for a zero-parameter status tool.

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?

The tool takes zero parameters, so the baseline is 4 and there is no parameter semantics to compensate for. Nothing in the description misrepresents the empty input contract.

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 states a specific resource: P5's mail/SMTP configuration (server, port, TLS, sender, login flag, recipients) plus delivery-log state and a fault summary. That is concrete enough for an agent to know it returns a diagnostic snapshot rather than performing an action. It does not explicitly name the sibling it differs from (notify_set for edits, notify_test for sending a test), so it falls short of a 5.

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: the phrase 'when mail is broken or silent' hints this is the troubleshooting/inspection step, and 'Read-only' implies the write path lives elsewhere. There is no explicit 'use this instead of X' routing to notify_set or notify_test, so an agent must infer the boundary.

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