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

With no annotations provided, the description carries the full burden and does well by disclosing key behavioral traits: it's a read-only operation (implied by 'get'), returns a string format with specific components (status label and numerical score), and explains what the composite metric considers (block production, hashrate, transaction volume). It doesn't mention rate limits or authentication needs, but covers the core behavior adequately.

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 perfectly concise and well-structured: three sentences that each earn their place by stating the purpose, output format, and metric composition without any wasted words. It's front-loaded with the core purpose and efficiently communicates essential information.

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's simplicity (0 parameters, no annotations, but has output schema), the description is complete: it explains what the tool does, what it returns, and how the metric is calculated. The output schema likely covers return structure details, so the description doesn't need to duplicate that, making this appropriately comprehensive for the context.

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 tool has 0 parameters with 100% schema description coverage, so the baseline is 4. The description appropriately doesn't discuss parameters, focusing instead on the output and purpose, which is correct for a parameterless tool.

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's purpose with specific verbs ('get a simplified health assessment') and resource ('Bitcoin network'), distinguishing it from siblings like get_bitcoin_network_overview or get_bitcoin_market_data by focusing specifically on health metrics rather than general data or market information.

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?

The description implies usage context by mentioning 'simplified health assessment' and 'single score and status label', suggesting it's for quick health checks rather than detailed analysis. However, it doesn't explicitly state when to use this versus alternatives like get_bitcoin_network_overview or what specific scenarios warrant this tool.

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