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 states that this is a check returning 'ok + note,' but it does not describe permission requirements, whether the check has side effects, error behavior, or what the note contains.

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 two short clauses with no waste. The action and return summary are front-loaded and immediately scannable.

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 simple one-parameter tool with complete schema coverage, the description provides the minimum needed to understand the call. However, the return value 'ok + note' is vague and there is no output schema to clarify it.

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 100%, so the sole parameter is already fully documented in the schema. The description only restates that the argument is an MCP tool name and adds no syntax or format details beyond the schema's example.

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 states a specific operation (check access) on a specific resource (a Pabandi platform tool identified by MCP tool name). It clearly distinguishes this meta access-check from the sibling tools, which perform actual platform actions.

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?

It does not say when an agent should call this check versus simply invoking the target tool, nor does it mention prerequisites, alternatives, or when not to use it. The intended usage is only implied by the phrase 'Check whether the caller can access.'

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