magicblock health

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

The description adds the cost ($0.01) which is not disclosed in annotations. Annotations do not indicate read-only status, but the description implies a read operation (health check). However, this is contradicted by readOnlyHint=false. The description could be clearer about side effects, but the cost is a useful behavioral trait.

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 concise sentence, front-loading the purpose and noting the price. No unnecessary words.

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 tool has no parameters and an output schema exists, the description is complete enough. It states the purpose and cost, which are the key pieces of information for this simple health-check tool.

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?

No parameters exist, and schema coverage is 100%. The description adds no parameter information, which is acceptable for a parameterless tool. Baseline score of 4 applies.

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 checks the health status of a specific API (MagicBlock Private Payments API). It uses a specific verb 'check' and resource, distinguishing it from other magicblock tools like magicblock_balance or magicblock_deposit.

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 explicit guidance on when to use this tool versus alternatives. The mention of price is relevant but does not substitute for usage context. Since the tool is simple, usage is implied but not explicitly stated.

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