  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 full burden. It mentions 'suggest an upgrade path' but doesn't disclose behavioral traits such as what data sources are used for comparison, whether suggestions include intermediate versions or breaking changes, error handling for invalid inputs, or performance/rate limits. This leaves gaps in understanding the tool's 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 front-loads the core functionality ('compare two versions and suggest an upgrade path') with zero redundant information. It's appropriately sized for the tool's complexity, 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 tool's complexity (version comparison with upgrade suggestions), lack of annotations, and no output schema, the description is incomplete. It doesn't explain what the upgrade path includes (e.g., step-by-step versions, compatibility notes), potential outputs, or error conditions. This inadequately supports an agent in understanding the tool's full behavior and results.

  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 fully documents parameters (dependency, currentVersion, targetVersion). The description adds minimal value beyond the schema by implying the tool compares versions and suggests upgrades, but doesn't provide additional semantic context like format constraints or interaction effects between parameters. Baseline 3 is appropriate as the schema handles parameter documentation.

  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 tool's purpose with specific verbs ('compare' and 'suggest an upgrade path') and identifies the resource ('two versions'). It distinguishes from siblings like 'check_version_exists' (verification) and 'get_all_versions' (listing), though it could be more explicit about the comparison scope (e.g., dependency compatibility).

  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?

  The description implies usage for version comparison and upgrade planning, but lacks explicit guidance on when to use this tool versus alternatives like 'get_latest_stable_version' (which might provide target versions) or prerequisites. It suggests an optional 'targetVersion' but doesn't clarify trade-offs between specifying it or relying on the tool's suggestion.

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

• check_version_existsA
  3.7/5.0
  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 for behavioral disclosure. While 'Verify' implies a read-only check, the description doesn't specify what constitutes 'exists' (e.g., in a repository, locally cached, etc.), authentication requirements, rate limits, error conditions, or return format. For a tool with zero annotation coverage, 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.

  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 unnecessary words. It's appropriately sized for a simple verification tool and front-loads the core functionality immediately.

  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 the tool's moderate complexity (2 required parameters, no output schema, no annotations), the description provides adequate basic purpose but lacks important contextual details. It doesn't explain what the verification checks against (e.g., Maven Central repository), what the return value indicates (boolean, status code, etc.), or error handling. The description is complete enough for basic understanding but insufficient for full operational context.

  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 both parameters clearly documented in the input schema. The description adds no additional parameter information beyond what's already in the schema. According to scoring rules, when schema coverage is high (>80%), the baseline score is 3 even with no parameter details in the description.

  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 specific action ('Verify if exists') and resource ('specific version for a Maven dependency'), using precise terminology. It distinguishes this tool from its siblings (compare_versions, get_all_versions, get_latest_stable_version) by focusing on existence checking rather than comparison or retrieval operations.

  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 implies usage context through the phrase 'specific version,' suggesting this tool is for checking existence of particular versions rather than retrieving version lists or comparing versions. However, it doesn't explicitly state when to use this tool versus alternatives like get_all_versions or get_latest_stable_version, nor does it mention exclusion criteria.

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

• get_all_versionsA
  3.7/5.0
  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 mentions filtering to stable versions, which adds some context, but lacks details on permissions, rate limits, error handling, or what the return format looks like (e.g., list structure, ordering). For a tool with no annotations, this leaves significant gaps in understanding how it behaves beyond the basic functionality.

  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 front-loads the core purpose ('List all available versions for a Maven dependency') and adds necessary qualification ('optionally filtering to stable versions only'). Every word earns its place, with no redundancy or waste, 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 the tool's moderate complexity (3 parameters, no output schema, no annotations), the description is adequate but incomplete. It covers the basic purpose and filtering option, but without annotations or output schema, it lacks details on behavioral aspects like response format, error cases, or usage constraints. This results in a minimal viable description with clear gaps for an agent to rely on.

  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 all parameters thoroughly. The description adds minimal value beyond the schema by implying the 'stableOnly' parameter's effect ('optionally filtering to stable versions only'), but does not provide additional syntax or format details. This meets the baseline score of 3 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.

  Purpose5/5

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

  The description clearly states the specific action ('List all available versions') and resource ('for a Maven dependency'), and distinguishes it from siblings by specifying the scope of versions returned. It explicitly mentions optional filtering to stable versions only, which differentiates it from tools like 'get_latest_stable_version' that might return only one version.

  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 provides clear context on when to use this tool ('List all available versions... optionally filtering to stable versions only'), which implies it's for retrieving multiple versions rather than checking existence or comparing. However, it does not explicitly state when not to use it or name alternatives among the siblings, such as using 'check_version_exists' for a single version check or 'get_latest_stable_version' for just the latest stable version.

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

• get_latest_stable_versionA
  3.7/5.0
  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 describes the filtering logic (excluding unstable versions) but lacks details on error handling, rate limits, authentication needs, or what happens if no stable version exists. For a tool with no annotation coverage, this leaves significant gaps in understanding its operational behavior.

  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 front-loads the core purpose and includes necessary exclusions without redundancy. Every word earns its place by clarifying the tool's scope and differentiating it from potential alternatives, 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 the tool's moderate complexity (single parameter, no output schema, no annotations), the description covers the core functionality and version filtering well. However, it lacks details on return values, error cases, or behavioral traits, which are important for a tool with no annotations. It is adequate but has clear gaps in completeness.

  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 parameter 'dependency' fully documented in the schema as a Maven coordinate. The description does not add any additional semantic information about the parameter beyond what the schema provides, such as examples or constraints not covered. Baseline 3 is appropriate since 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.

  Purpose5/5

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

  The description clearly states the specific action ('Get the latest stable version') and resource ('for a Maven dependency'), with explicit exclusions that distinguish it from sibling tools like 'get_all_versions' or 'check_version_exists'. It precisely defines what constitutes 'stable' by listing excluded version types (SNAPSHOT, alpha, beta, etc.).

  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 implicitly provides usage context by specifying it returns only stable versions, which helps differentiate it from siblings that might return all versions or check existence. However, it does not explicitly state when to use this tool versus alternatives like 'get_all_versions' or 'compare_versions', nor does it mention any prerequisites or exclusions beyond the version filtering.

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