analyze_block

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

No annotations are provided, so the description carries the full burden. It discloses what aspects of the block get analyzed (behavioral scope), but fails to indicate operational safety (read-only vs destructive), error handling for invalid blocks, or rate limiting characteristics.

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 appropriately compact with no wasted words. The 'Args:' section structures the parameter documentation clearly, though the format is somewhat docstring-like rather than natural prose. Every sentence earns its place by conveying purpose or parameter semantics.

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 that an output schema exists (relieving the description from detailing return values) and only one parameter requires documentation, the description is largely complete. It covers the parameter gap in the schema and lists the analysis scope. A brief note confirming this is a read-only operation would have made it fully complete given the lack of annotations.

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?

With 0% schema description coverage (the height_or_hash property lacks a description field), the description provides crucial compensation by explaining the parameter accepts either 'Block height' or 'block hash' and provides a concrete example ('939290'). This adds significant semantic value beyond the raw schema.

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 verb (analyze) and resource (block), and specifically lists analysis dimensions (mining pool, SegWit/Taproot adoption, fee distribution, revenue) that distinguish it from siblings like get_block_stats or compare_blocks. However, it doesn't explicitly articulate how it differs from analyze_transaction or analyze_mempool.

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 when-to-use or when-not-to-use guidance is provided, nor are alternatives named. However, the specific analysis dimensions listed (SegWit/Taproot adoption, revenue) imply this tool is intended for deep economic/technical block analysis rather than basic block retrieval, providing implied usage context.

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