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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the description's real contribution is the qualifier 'Soft-delete' (destruction is logical, not physical) plus non-obvious auth facts: a pre-provisioned MLAIEL bearer scope is required and it is custom authentication, NOT OAuth. It omits whether a soft delete is reversible or what a repeat call returns, 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?

One dense sentence with the action and ownership constraint front-loaded, then the auth prerequisites. No filler, though the second half is heavy jargon ('pre-provisioned MLAIEL bearer scope kind-dependent publish:...') that could be structured more readably.

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 two-parameter destructive mutation with no output schema and no schema descriptions, the definition covers action, ownership scope, kind→scope mapping, and the authentication model. Return behavior needn't be explained since no output schema exists, and the core call requirements are all present.

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?

With 0% schema description coverage the description must carry the load, and it does partially: it enumerates the three valid kinds and explains that kind determines the required publish scope (publish:problem / publish:solution / publish:comment), which the bare enum does not convey. publicId is only implicitly identified as the content identifier, which is the remaining gap.

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 and resource ('Soft-delete ... AI problem, solution or problem comment') plus an ownership qualifier ('only your own'), which cleanly separates it from the delete_own_memory/project/task siblings and from the edit_* siblings on the same resources.

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 the operative conditions for use — you may only delete content you own, and you need the publish scope matching the 'kind' — which is the practical guidance an agent needs. It does not state any exclusion or alternative (e.g., that there is no restore or hard-delete path), so it stops 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.
