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

Annotations already declare destructive=true, idempotent=true, openWorld=true and readOnly=false, so the safety and repeatability profile is covered without the description. The description adds useful scope context (this only clears brand-memory rules, not Knowledge-settings rules) but says nothing about reversibility, permissions, or return behavior. With annotations carrying the burden, a 3 is appropriate.

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 with the destructive action and its id source front-loaded, followed by the scope caveat. No filler.

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 destructive delete with a rich annotation set and only three parameters, the description covers purpose, id provenance, and scope boundaries. With annotations supplying safety/idempotency and no output schema to explain, nothing essential is missing.

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 only 33%: id and workspaceId have no schema descriptions, while idempotencyKey is fully documented. The description compensates for id by noting it comes from get_brand_memory and implies workspace scoping, but leaves workspaceId unexplained. Partial compensation against a low coverage baseline.

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 specific verb (Delete), resource (one brand rule), and scope (from this workspace), and specifies the id source (get_brand_memory). It also distinguishes itself from remember_brand_fact and the Knowledge-settings concept, so an agent can identify the operation without opening the 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 a clear condition for use (deleting a single brand rule by id from get_brand_memory) and an explicit exclusion (rules written in Knowledge settings are changed there, not here). It does not name the sibling/alternative tool that handles the Knowledge-settings case, but the when/when-not boundary is nonetheless clear.

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