banned_players_list

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

Even without annotations, the description clearly frames this as a read-only operation by stating 'Read the current banned-players.json contents.' It signals that no server mutation or state change occurs. It does not describe output format or edge cases, but for a simple no-parameter file read this is reasonably transparent.

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, short sentence of about eight words. Every word adds information: it names the verb, clarifies the resource is the banned-players.json file, and emphasizes it reflects the current contents. There is no redundant or filler text.

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?

For a tool with no parameters, no annotations, and no output schema, the description gives enough high-level context to understand it as a plain read of the banned-players file. It could theoretically state the exact return representation, but naming the file and saying 'contents' makes the expected behavior clear for a simple reader.

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 there is little for the description to clarify beyond what the schema shows. The baseline of 4 applies because parameter semantics are trivially complete; the description cannot add meaningful parameter nuance to a tool with no inputs.

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 ('Read') and a specific resource ('current banned-players.json contents'). This clearly distinguishes it from sibling tools like banned_ips_list, players_list, and whitelist_list, since it targets the banned-players file specifically.

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 description implies when this tool is useful: whenever the agent needs the current list of banned players from the banned-players.json file. However, it gives no explicit guidance about alternatives, such as when to use banned_ips_list or whitelist_list instead, and no exclusions are mentioned.

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