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

Annotations already declare destructiveHint=true and idempotentHint=true, so the irreversibility warning reinforces rather than replaces structured data. The description adds genuinely new context: that no extra sign-in is needed and that the connected Himalayas account is used, plus the user-confirmation workflow. It doesn't describe failure modes (e.g., deleting a non-existent id), holding it short of a 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?

Three short sentences, action and target front-loaded, followed by the destructive warning and the auth note. No sentence is filler and nothing important is buried.

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 delete with no output schema, the definition covers everything an agent needs: what is deleted, how it is identified, that it is irreversible, that confirmation is required, and that no additional authentication step is involved.

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 documented as an education id sourced from get_my_profile. The description only restates 'by id' without adding format or retrieval nuance, so the schema is doing the work — the baseline 3 for high coverage 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?

States a specific verb (delete), resource (education entry), scope (your Himalayas profile), and keying mechanism (by id). An agent can distinguish this from delete_experience, delete_document, and update_education 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 one actionable precondition, 'confirm with the user first,' which is real guidance for a destructive call. However, it never names alternatives (e.g., update_education to amend rather than remove, delete_experience for a different resource) or states when deletion is inappropriate, leaving routing inferred.

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