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

With no annotations, the description carries the full behavioral burden. It usefully discloses that the MCP tool only reads task-board information, that viewing is free, that completed work can earn credit, and that a key credential is required. However, it also spends substantial space on separate POST endpoints and pilot conditions that do not describe this MCP tool, leaving the actual invocation behavior only partially clarified.

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 long and overloaded with details about separate pilot POST endpoints, role keys, and disabled delivery conditions that are not relevant to invoking this MCP tool. It is front-loaded with the user scenario, but many sentences do not earn their place for an agent trying to call a zero-parameter read tool.

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?

There are no annotations, no output schema, and no parameters, so the description must carry considerable context. It provides purpose, cost, credential, and read-only behavior, but it does not describe what the returned eligible fees or task-board information look like, and its inclusion of unrelated endpoint behavior creates ambiguity rather than completeness.

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 and schema coverage is 100%, so the baseline for parameter semantics is 4. The description adds no parameter-level information, but none is needed for a no-parameter read tool.

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 clearly states the tool shows eligible court fees by case and provides task-board access for earning fee credit. This is a specific resource and scope, distinguishable from fee and payment siblings. It falls short of a 5 because it mixes in unrelated pilot endpoint behavior and never crisply names the tool's own action beyond 'shows'.

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 opening scenario implies when an agent would use this tool: when the user owes court fees and wants to earn credit through work. However, it does not explicitly compare this tool with alternatives such as fee_quote, payment_status, or pay_ledger, and gives no when-not guidance. Usage is implied rather than stated.

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