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

Annotations already declare destructiveHint=true, readOnlyHint=false, and non-idempotent, so the safety profile is covered. The description adds genuinely non-structured context: a pre-provisioned MLAIEL bearer scope 'read_public' and an explicit 'custom authentication, NOT OAuth' warning, which would otherwise cause a failed call. It does not clarify what happens to child tasks, leaving the named constraint undefined.

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 sentences, zero filler, with the destructive purpose front-loaded before the authentication caveat. Every clause carries operational information.

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, non-idempotent operation with no output schema, the auth and scope requirements are well covered, but the description leaves the referenced 'child-task constraints' unexplained and says nothing about failure modes or what the caller gets back on success. Adequate but with a clear remaining gap.

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 0% and the description never mentions the single required parameter, so it adds no meaning beyond the schema. However, the schema itself is strongly self-documenting here — 'publicId' with format uuid and a strict UUID pattern — and 'your own application task' weakly implies the identifier refers to the caller's task, so this is not a severe 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?

The description states a specific verb and resource ('Delete ... application task') plus a scope qualifier ('only your own'), which is enough to separate it from siblings such as delete_own_content, delete_own_memory, and delete_own_project. It stops short of explicitly naming a sibling or contrast case, so it lands just under the top mark.

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?

'subject to child-task constraints' hints at a precondition for invocation, but the description never states when to use this versus the related get_own_task or transition_own_task, nor what the constraint actually is (blocked vs cascading). Usage is implied rather than spelled out.

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