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

Discloses that the tool is paid ($0.00015 in KAS), a key behavioral trait. Since no annotations are provided, the description carries the full burden, and it adds important cost context. Lacks details on potential failures or side effects, but adequate for a simple read-only tool.

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?

Extremely concise: one sentence summarizing the tool's output plus a brief cost note. No wasted words, front-loaded with key metrics.

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?

Lists the returned metrics but does not describe the output format or structure. Without an output schema, the description could be more precise about how the data is presented. Adequate but leaves some ambiguity.

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%. Baseline of 4 applies per guidelines.

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?

Clearly states the tool returns Kaspa mainnet status metrics like DAA score, block count, difficulty, and node sync state. Distinguishes from sibling Kaspa tools (balance, fee estimate, etc.) that serve different purposes.

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 guidance on when to use this tool versus alternatives. Does not mention any prerequisites or exclusions.

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