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

No annotations are provided, so the description carries the full burden. The mention that the event must be 'signed' is a useful precondition, but nothing is said about authorization, idempotency, what happens if the signature is invalid, or what the call returns. For a submission tool with zero annotation coverage this is a thin disclosure.

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?

A single tight sentence with the core action front-loaded and the next step appended. Nothing is wasted, though the extreme brevity shades into under-specification rather than true conciseness.

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?

With a required nested object that has no schema description, no output schema, and no annotations, the description leaves key gaps: how to construct the signed event object and what a successful submission yields. Given the complexity of a signed-event submission pipeline, more context is needed.

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 50%. The description adds meaning for the undocumented 'event' object by indicating it is a signed kind 30023 event, which the bare schema does not convey. It says nothing about the internal structure of that nested object, so it only partially compensates for the coverage gap; 'format' is already fully documented in the schema.

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 ('Submit') and resource ('signed kind 30023 paper event'), which is more precise than a generic 'submit paper'. It also names the sibling upload_fulltext as the follow-on step. The 'kind 30023' jargon is domain-specific but does identify the exact resource type, and no other sibling covers paper-event submission.

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 'then upload_fulltext' clause gives implicit workflow ordering, telling the agent this is a first step in a two-tool pipeline. However, it does not state when to prefer this over publish_event, nor any prerequisites beyond 'signed', leaving the agent to infer when this tool is the right choice.

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