reentranceTicket

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It only says 'Retrieves', implying a read operation, but discloses nothing about side effects, authentication requirements, or return behavior. The complete absence of context makes this inadequate.

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 very short (one sentence), but this is under-specification rather than concise clarity. It fails to provide any additional context about the ticket or its purpose, so the single sentence does not earn its place as a useful tool description.

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?

Given the low complexity (no params, no output schema) and no annotations, the description should at least explain what a reentrance ticket is, what it returns, or when it is used. The description offers none of this, leaving the agent completely uninformed about the tool's practical purpose.

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?

The tool has zero parameters, so the schema coverage is trivially 100%. According to the rules, a baseline of 4 applies for tools with no parameters. The description adds no parameter information, but none is needed since there are no parameters to explain.

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 uses a specific verb 'Retrieves' and a clear resource 'reentrance ticket', which distinguishes it from all sibling tools (none of which mention tickets). Even though the resource is somewhat domain-specific, the verb+resource structure clearly states what the tool does.

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?

No guidance is provided about when to use this tool or how it relates to alternatives like login/logout/dropSession. There is no mention of prerequisites, context, or exclusions, so the agent receives no usage direction.

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