Disambiguation4/5
Most tools have distinct purposes, but there is overlap between get_address_overview and get_info_about_address, as well as between get_10_latest_blocks_informations and get_summary_of_latest_block. Descriptions help differentiate, but some ambiguity remains.
Naming Consistency4/5
Tools consistently use snake_case with a 'get_' prefix, but naming patterns vary in specificity and style (e.g., 'get_10_latest_blocks_informations' vs 'get_summary_of_latest_block'). Minor inconsistencies like 'informations' (grammatical error) and varying verbosity.
Tool Count4/5
23 tools is a reasonable number for a comprehensive Bitcoin information server. The scope is broad, covering network, transactions, mining, and market data, and each tool serves a clear purpose.
Completeness5/5
The tool set thoroughly covers Bitcoin-related queries: network stats, addresses, transactions, blocks, mining pools, fees, market data, sentiment, and trending crypto/NFTs. No obvious gaps for typical informational needs.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description bears full burden. Only states returns string format and accepted address formats. Does not disclose any behavioral traits like read-only nature, error conditions, or idempotency. For a read operation, minimal but insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise: one sentence for purpose, bullet list of outputs, one line for accepted formats, one line for use case. No wasted words; all content is relevant and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Output schema exists, so return values are covered externally. Description adds context on address format and use cases. Lacks error handling or edge cases, but for simple tool with output schema, generally complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so description must add value. It specifies accepted address formats (base58 or hash160), which is helpful but minimal. No examples, length constraints, or validation details. Adds some meaning but not substantial.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states the tool provides a simplified overview of a Bitcoin address with balance and cumulative totals. Lists specific metrics returned. Slightly differentiated from sibling 'get_info_about_address' by emphasizing 'simplified' vs 'granular details', but no explicit comparison.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says 'when you need a quick financial summary without granular details', which provides appropriate context for use. However, no explicit when-not or alternative tools are mentioned; guidance is implicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully inform about behavior. It describes the return format (status label and score) and what the score considers (block production, hashrate stability, transaction volume). However, it does not disclose potential latency, caching behavior, or data freshness.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two short paragraphs, front-loaded with the purpose. Every sentence provides essential information—purpose, return format, and composition of the score. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no parameters and an output schema, the description adequately explains the return value. It could mention if the tool is free or requires authentication, but for a public network health check, it is sufficiently complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are no parameters, so the baseline is 4. The description adds value by explaining the output format and the factors considered in the health score, which is beyond what the empty schema provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool provides a 'simplified health assessment' with a single score and status label. The verb 'get' and resource 'Bitcoin network health' are specific. It distinguishes itself from sibling tools like get_bitcoin_network_overview which likely provides more detailed data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description starts with 'Use this to get a simplified health assessment' which clearly indicates the intended use case. It doesn't explicitly state when not to use or mention alternatives, but the context of sibling tools implies for more detailed data one should use other tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; description adds context on return format (string) and metrics but does not disclose read-only nature or any side effects, which is acceptable for a query tool but the burden is higher without annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Well-organized with sections and bullet points; front-loaded with purpose. Could be slightly leaner but efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Complete for a tool with no parameters and an output schema; description explains all return fields and use cases, leaving no ambiguity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema is empty; no parameters to document. Baseline is 4; description adds value by detailing output structure, which compensates for lack of parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it returns aggregate statistics of Bitcoin mining pool ecosystem with specific metrics like total pools, blocks, dominance, etc. It is distinct from siblings like get_mining_pool_by_slug or get_top_10_mining_pools_rank.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit use cases ('assess centralization risk', 'compare gap between dominant and small pools') but does not mention when to avoid or alternatives among siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It discloses that fees are dynamic based on network conditions and lists the four priority levels with details. However, it lacks information on rate limits, authentication, or error handling, but these are not critical 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with bullet points and front-loaded purpose. It is not overly verbose; each sentence adds information. Could be slightly more concise, but still effective.

Given no parameters and an output schema (not shown), the description fully explains the return format, priority levels, and dynamic nature. It covers all necessary context for an agent to use the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameters exist (schema coverage 100%). With 0 parameters, the baseline is 4. The description adds value by explaining the output, which is more important than parameter info.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'get current recommended Bitcoin transaction fees for different confirmation speed priorities.' It specifies the resource (Bitcoin transaction fees) and the action (get). Among sibling tools, none overlap, providing clear differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes explicit use cases: 'When you need to know how much to pay for a Bitcoin transaction, to optimize transaction costs vs. speed, or to check if the network is congested.' It does not mention when not to use, but the narrow scope makes it obvious.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so description carries full burden. It describes the return format as string and lists metrics, but does not disclose potential behaviors like caching, update frequency, or authentication requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
