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

Annotations already declare read-only, non-destructive, closed-world behavior, so the safety profile is covered; the description adds genuinely new behavioral context by stating the required subscription ('Cere un abonament care include Dosare Instanta'). It does not describe failure modes for a bad or missing id, which keeps it below 5.

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?

A single front-loaded sentence: resource and lookup key first, then the content enumeration, then the subscription caveat. The content list is long but each item conveys what the agent will receive, so the density is justified rather than padded.

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 enumeration of returned sections (hearings, solutions, parties, key facts, associated files, court route, BPI publications) usefully substitutes for it, and the subscription requirement is covered. A note on behavior for an unknown id would make it fully complete.

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 single parameter is fully documented in the schema, including that the id originates from dosare_instanta, so the description adds no meaning beyond the structured field. Baseline 3 applies.

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?

It states a specific verb-and-resource ('Detaliul unui dosar de instanta dupa id') and then enumerates the returned content (hearings, solutions, parties, key facts, associated files, court route, BPI publications), so the agent can distinguish it from the list-style sibling dosare_instanta without opening either schema.

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 signals the use condition by tying the id to 'din dosare_instanta', which tells the agent to obtain the identifier from the sibling tool first, and it flags the subscription prerequisite. It does not state explicit exclusions or alternatives beyond that, so it falls short of a 5.

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