get_chain_tx_stats

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

No annotations provided, so description carries full burden. Adds valuable Bitcoin-specific context that 2016 blocks equals ~2 weeks (difficulty adjustment period), explaining the averaging behavior. However, lacks details on return format, rate limiting, or computational cost despite having no annotation coverage.

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?

Appropriately brief with front-loaded purpose statement followed by Args section. Two sentences efficiently convey essential information without redundancy, though 'Args:' formatting is slightly technical.

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?

Adequate for a single-parameter statistical getter where output schema exists (no return value description needed). The ~2 weeks context provides sufficient domain context for Bitcoin operations, though mentioning what specific statistics are returned (TPS, volume, etc.) would strengthen completeness.

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?

Compensates effectively for 0% schema description coverage by explaining nblocks semantics ('Number of blocks to average over') and the significance of the default value (2016 = ~2 weeks). Could improve by mentioning valid ranges or edge cases, but adequately documents the single parameter.

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?

Clear verb ('Get') and resource ('transaction rate statistics') with scope ('over N blocks'). Distinguishes from sibling tools like get_block_stats by specifying 'transaction rate' rather than general block data, though could explicitly contrast with chain analysis alternatives.

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?

Provides no explicit guidance on when to use this versus alternatives like get_block_stats or analyze_block. The default value explanation (2016 = ~2 weeks) implicitly suggests usage patterns but lacks explicit 'when-to-use' or prerequisite guidance.

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