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

Annotations already carry the important profile (destructiveHint=true, readOnlyHint=false, idempotentHint=false), so the bar is lower. The description adds the action vocabulary but does not disclose which actions are irreversible, what 'delete' actually removes, or whether any action requires confirmation — context the annotations don't supply.

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 short sentences, front-loaded with the effect summary before the action list, with no filler. Listing all seven actions partly duplicates the enum, but it conveys the verb semantics the enum alone doesn't.

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, multi-action tool with no output schema and a free-form nested params object, the description gives a discovery path but no return-value or failure expectations, and no indication of which of the seven actions cause irreversible data loss. Adequate but with clear gaps.

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 67%, with 'params' being a free-form object (additionalProperties: true) whose fields are entirely undocumented in the schema. The description compensates partially by routing the agent to action 'help', but it never describes the per-action fields itself.

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 concrete verbs (improve, keep, edit, delete) against a named resource (answers in the library), and the action enumeration makes the tool's scope unambiguous. It implicitly separates itself from the read-only get_answers sibling, though it never names that sibling explicitly.

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?

The only real guidance is the discovery hint 'Call with action "help" for each action's fields,' which is useful but procedural rather than situational. Nothing says when to use this versus get_answers/manage_applications, nor any precondition for the write actions.

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