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

With readOnlyHint=true already covering the safety profile, the description still adds real behavioral context: it clarifies that no invoices are required as input and that the tool does not author the declaration itself. It stops short of describing pagination or exactly how the deadline is computed.

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?

Two tight sentences: the first front-loads what is returned, the second handles the scope boundary. No filler, and each clause carries information the agent needs.

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 convey return content, and it does: notification, filing deadline, and remaining days. Combined with the input-exclusion notes, an agent has everything needed to invoke it correctly.

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?

There is a single parameter (cui) at 100% schema description coverage, so the schema already carries the meaning. The description adds nothing parameter-specific, which is the expected baseline of 3 when the schema does the heavy lifting.

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 and scope: for an insolvent firm it returns the opening notification, the deadline for registering the claim with the creditors' mass, and the days remaining. This is clearly distinct from siblings like tabel_creditori or adunari_creditori, which deal with creditor tables and meetings rather than the registration deadline.

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 names the triggering condition (a firm that has entered insolvency) and explicitly excludes adjacent work: it does not draft the declaration and does not need invoices, redirecting that generation to 'DateBPI, fila Declaratie de creanta.' That is clear when/when-not guidance, though no sibling tool is named as the alternative endpoint.

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