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

The description is at odds with the annotations: it states the listing is removed 'for good' and 'cannot be undone,' yet destructiveHint is false, which declares a non-destructive operation. Because the annotation is the signal agents rely on to gate confirmation, this conflict is dangerous. The otherwise-useful details (irreversibility, per-tool confirmation default, Cotlet API key requirement) do not offset the contradiction.

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?

Reasonably front-loaded, but 'Remove one of your listings from the portal for good' and 'Deletes the listing from the portal' duplicate the same fact, and the confirmation requirement is mentioned twice (default confirm plus 'confirm with the user before each call'). Minor trimming would help.

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 one-parameter mutation with no output schema, the description covers the key operational facts an agent needs: semantics, irreversibility, confirmation policy, and auth. It would be fully complete if it also resolved the destructive/non-destructive question and named a reversible alternative.

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 there is only one parameter, whose description ('Listing ID from list_listings') already explains its origin. The prose adds nothing further about listing_id, so baseline 3 is appropriate.

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?

States a precise verb (remove/delete) and resource (one of your own listings) with clear scope. An agent can immediately distinguish it from immobiliare_update_listing, immobiliare_create_listing, or immobiliare_get_listing without opening any 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?

Gives clear operating context — permanent removal, cannot be undone, and a user-confirmation requirement — which frames when this tool is appropriate. It stops short of naming the alternative (e.g., deactivate/update for a reversible hide), so routing is implied rather than explicit.

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