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

With no annotations, the description carries the full burden. It discloses one useful behavioral trait -- that omitting the call yields an SDK default -- but says nothing about side effects, whether the defence decision is reversible, what 'refused' or 'forkSave' cause, or what happens on an invalid choice.

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?

It is a single compact sentence with no filler, and the override behavior is placed in a parenthetical rather than front-loaded. The dense brace notation makes it harder to parse than its length warrants.

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?

A four-parameter, zero-coverage, unannotated tool with no output schema needs far more semantic detail than this. The description explains neither the meaning of the answer fields nor the consequences of the defence choice, leaving the agent unable to invoke it confidently.

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%, so the description must compensate, yet it only repeats the parameter names and the inner/outer enum without explaining what 'success', 'refused', or 'forkSave' mean or how they interact. 'as the prompt allows' hints at conditional validity but gives no rule.

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 names an action ('Answer the open defence prompt by hand') but 'defence prompt' is never defined and none of the cryptic siblings (act, bureau, enter, etc.) clarify the domain. An agent learns the payload shape but not what the tool actually accomplishes or when its effect matters.

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 parenthetical '(the SDK answers it with the plain default when you do not)' gives one real usage signal: call this to override the default answer. However there is no guidance on when not to call it, what the default is, or how it relates to siblings like act or order_formation.

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