Tool Scores

• analyze_metricsC
  2.6/5.0
  Behavior2/5

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

  No annotations are provided, so the description carries full burden. It mentions 'categorize them with explanations', hinting at output behavior, but doesn't disclose critical traits: whether this is a read-only analysis, if it modifies data, what the output format is (e.g., text, structured data), or any performance considerations like latency or rate limits. For a tool with no annotations, this leaves significant behavioral gaps.

  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 a single, efficient sentence that states the core action and output. It's front-loaded with the main purpose and avoids unnecessary words. However, it could be more structured by explicitly separating analysis from categorization, but given its brevity, it earns a high score for conciseness with minor room for improvement in clarity.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness2/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the tool's complexity (analysis implies some processing), lack of annotations, and no output schema, the description is incomplete. It doesn't explain what 'analyze' entails, what the output looks like (e.g., explanations format), or any error conditions. For a tool with one parameter but undefined behavior and output, more detail is needed to make it fully usable by an agent.

  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 description coverage is 100%, with the single parameter 'category' fully documented in the schema (including enum values and description). The description adds no additional meaning beyond the schema, such as explaining how categorization interacts with analysis or default behaviors when no category is specified. With high schema coverage, the baseline score of 3 is appropriate as the description doesn't compensate but doesn't detract.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose3/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description 'Analyze metrics and categorize them with explanations' states a general purpose but lacks specificity about what 'analyze' entails (e.g., statistical analysis, trend detection, anomaly identification). It distinguishes from 'list_metrics' (which likely just lists) and 'generate_dashboard' (which likely creates visualizations), but doesn't clearly differentiate from 'search_rust_code' (unrelated). The verb 'analyze' is somewhat vague without elaboration on the analytical method.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description provides no guidance on when to use this tool versus alternatives like 'list_metrics' or 'generate_dashboard'. It doesn't mention prerequisites, such as needing metrics data to be available, or exclusions, like when simpler listing might suffice. Usage is implied only by the tool name and general purpose, with no explicit context or comparison to siblings.

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

• generate_dashboardC
  2.9/5.0
  Behavior2/5

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

  No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool generates JSON but doesn't describe what happens after generation (e.g., is it saved, displayed, or returned as output?), whether it requires specific permissions, or any side effects. This is inadequate for a tool that likely creates or outputs data.

  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 a single, efficient sentence that directly states the tool's purpose without any wasted words. It is appropriately sized and front-loaded, making it easy to parse quickly.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness2/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the complexity (a generation tool with no annotations and no output schema), the description is incomplete. It doesn't explain what the output looks like (e.g., JSON structure), how the metrics are selected, or any behavioral traits. For a tool that likely produces significant output, this leaves critical gaps for an agent.

  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 description coverage is 100%, so the schema already documents both parameters thoroughly (category with enum values and dashboard_name). The description adds no additional meaning beyond implying the parameters influence the dashboard generation, which the schema already covers. Baseline 3 is appropriate when the schema does the heavy lifting.

  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?

  The description clearly states the verb ('generate') and resource ('Grafana dashboard JSON'), making the purpose understandable. However, it doesn't distinguish this tool from its siblings (analyze_metrics, list_metrics, search_rust_code), which all deal with different operations on metrics/code rather than dashboard generation.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, when not to use it, or how it relates to sibling tools like analyze_metrics or list_metrics. The agent must infer usage from the purpose alone.

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

• search_rust_codeC
  2.9/5.0
  Behavior2/5

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

  With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool searches for metric definitions but doesn't describe what constitutes a 'metric definition' in this context, how results are returned (e.g., format, pagination), or any limitations (e.g., search scope, performance). This leaves significant gaps for a search operation.

  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 a single, efficient sentence that directly states the tool's purpose without any redundant or unnecessary words. It is appropriately sized and front-loaded, making it easy for an agent to parse quickly.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness2/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the complexity of searching a codebase for metric definitions, with no annotations and no output schema, the description is incomplete. It doesn't explain what a 'metric definition' entails in Rust code, how results are structured, or any behavioral nuances, leaving the agent with insufficient context for effective use.

  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?

  The schema description coverage is 100%, with the single parameter 'metric_name' documented as 'Name of the metric to search for in the codebase'. The description adds no additional meaning beyond this, such as examples of metric names or search behavior details. Baseline 3 is appropriate as the schema handles the parameter documentation adequately.

  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?

  The description clearly states the action ('Search for metric definitions') and target resource ('in the Solana Rust codebase'), providing a specific verb+resource combination. However, it doesn't explicitly differentiate from sibling tools like 'analyze_metrics' or 'list_metrics', which might also involve metrics in some way.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description provides no guidance on when to use this tool versus alternatives like 'analyze_metrics', 'generate_dashboard', or 'list_metrics'. It doesn't mention prerequisites, exclusions, or specific contexts for usage, leaving the agent to infer based on tool names alone.

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

• list_metricsB
  3.2/5.0
  Behavior2/5

  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 states the action ('List all available metrics') but lacks behavioral details such as permissions needed, rate limits, pagination, or what 'available' entails (e.g., filtered by access). For a tool with zero annotation coverage, this is a significant gap in transparency.

  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 a single, efficient sentence with zero waste. It's front-loaded with the core action ('List all available metrics') and includes essential context ('from the sol_metrics InfluxDB database'). Every word earns its place, making it highly concise and well-structured.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness3/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given 0 parameters and no output schema, the description is minimally complete for a simple listing tool. However, with no annotations and no output details, it lacks behavioral context (e.g., response format, error handling). It's adequate but has clear gaps, making it a minimum viable description.

  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?

  The tool has 0 parameters, and schema description coverage is 100%, so there are no parameters to document. The description doesn't need to add parameter semantics, and it appropriately doesn't mention any. A baseline of 4 is applied for zero-parameter tools, as there's nothing to compensate for.

  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?

  The description clearly states the verb ('List') and resource ('all available metrics'), specifying the source ('from the sol_metrics InfluxDB database'). It distinguishes from siblings like 'analyze_metrics' (analysis vs listing) and 'generate_dashboard' (creation vs listing), though not explicitly. However, it doesn't fully differentiate from 'search_rust_code' (different domain), so it's not a perfect 5.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description provides no guidance on when to use this tool versus alternatives. It doesn't mention when to use 'list_metrics' over 'analyze_metrics' or 'search_rust_code', nor does it specify any prerequisites or exclusions. This leaves the agent with minimal context for tool selection.

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