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

Annotations already establish readOnly/idempotent/non-destructive, so the safety profile is covered; the description adds value by disclosing the payload contents (last verdict, last check date, recent verdict changes) and that the call is free. It does not state pagination, ordering, or an item cap, which is the remaining gap for a list operation.

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 no filler; every clause (followed companies, verdict, check date, recent changes, free) conveys something an agent would want before calling.

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?

There is no output schema, so the description must carry the return-value burden and it does by naming the four data points returned, and with no parameters nothing is left undocumented. The only shortfall is absence of result-size or ordering behavior, which matters somewhat for a list 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?

Zero parameters, so the baseline is 4. There is nothing for the description to disambiguate, and it correctly does not invent inputs.

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 a specific verb+resource, 'Lista firmelor pe care contul le urmărește' (the list of companies the account follows), and enumerates the fields it returns. It implicitly distinguishes itself from the action siblings urmareste_firma and opreste_urmarirea by being the listing counterpart, though it never names them 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?

It's clear from the wording when to consult this (to see what you follow), and 'Gratuit' signals no cost, which is a mild usage cue. But there is no explicit when-versus-when-not guidance or reference to the follow/unfollow siblings, so an agent must infer the boundary itself.

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