latest_blocktime_get

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

The description discloses that it returns a UNIX timestamp, but no annotations exist to provide safety cues. It does not explain behavior for the optional random_string parameter or mention any side effects, network behavior, or error conditions.

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?

Two sentences with no redundant information. Front-loaded verb and resource, followed by return value. Every sentence is essential.

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?

The description is adequate for a simple read operation but lacks explanation of the random_string parameter, output format, and error handling. Given no output schema, more context on return structure would help.

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 input schema has one parameter 'random_string' with 0% description coverage, and the tool description does not mention it at all. No meaning is added beyond the schema, leaving the parameter's purpose entirely unclear.

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 gets the timestamp of the latest Bitcoin block, with a specific verb 'Get' and resource 'timestamp of the latest block'. It distinguishes from sibling tools like latest_blockhash_get and latest_block_height_get.

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. The description does not mention scenarios, prerequisites, or exclude cases. Sibling tools are not referenced.

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