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

With no annotations, the description carries the full burden. It usefully discloses that an api_key with administrator privileges is required and that the block is temporary (implying reversibility via access_resume), but says nothing about what operations are blocked, side effects, or rate limits.

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 opening sentence is duplicated verbatim before the elaborated version, wasting space, and the javadoc-style @param/@return tags pad the text. The intent is still front-loaded and understandable.

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 two-param mutation tool with no annotations and no output schema, the description covers purpose, privilege requirement, and both parameters, but leaves the behavioral effect underspecified and the return value ('a json object') uninformative.

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, and it does document both parameters: api_key as the admin-privileged key and wallet_fk as the wallet to pause. It lacks format details (e.g. API key source) but covers the semantic intent of each param.

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?

States a specific verb+resource: temporarily blocks access to the wallet, and adds scope ('for all systems'). It is distinguishable from the write-side siblings, though it never names access_resume as its inverse, which would have made the pairing explicit.

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 when-to-use guidance, no statement of prerequisites beyond the admin key, and no reference to the obvious counterpart access_resume for undoing the pause. The agent must infer usage context entirely.

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