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

With no annotations provided, the description carries the behavioral disclosure burden. It explains that the operation closes an attempt and publishes an immutable success/failure card, conveying finality and irreversibility. It does not cover every side effect, but the immutable publishing detail is meaningful behavioral context beyond the tool name.

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?

The description is a single front-loaded sentence with no wasted words. It packs in the alias relationship, the core action, and the result characteristic into a compact, easily parseable statement.

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?

Although the core behavior is stated, three parameters remain undocumented and no output schema or annotations exist. The description is not rich enough for an agent to confidently know how to use export, next_candidate, or what the invocation returns beyond the notion of a published card.

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, but it says nothing about challenge_handle, export, or next_candidate. The parameter names give some self-evident hints, but the description adds no meaning about required input, defaults, or how these parameters affect behavior.

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 a specific action ('Close the attempt') and a specific outcome ('publish its immutable success or failure card'), and it identifies the tool as a compatibility alias for seal_attempt, which helps distinguish it from siblings. It is not a tautology and gives a clear object of the operation, though it relies somewhat on the seal_attempt reference for full grounding.

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 phrase 'Compatibility alias for seal_attempt' implies equivalence with a specific sibling and suggests when this tool would be chosen. However, it does not explicitly state when to prefer this tool over alternatives or when it should not be used, leaving usage context only implicit.

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