Tool Scores

• robosim_urdf_to_mjcfA
  3.5/5.0
  Behavior3/5

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

  Annotations already indicate readOnlyHint=true, destructiveHint=false, and idempotentHint=true, so safety profile is clear. The description adds context about transformation specifics (half-extents, radians, nested body tree), but does not disclose output format (no output schema) or error behavior, which are relevant beyond annotations.

  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, front-loaded sentence that efficiently conveys the core purpose and key transformation details with zero wasted words.

  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 simplicity (1 parameter, no output schema) and the presence of annotations, the description is adequate but could be improved by mentioning the output format (MJCF XML) or any constraints (e.g., validation, file size limits). The lack of output schema increases the need for such information.

  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 input schema already describes the sole parameter 'urdf' as 'The URDF XML text.' (100% schema coverage). The description adds no additional semantics beyond what the schema provides, so the baseline score of 3 is appropriate.

  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 converts a URDF to MJCF XML, uses a specific verb ('Convert'), and adds transformation details ('correct half-extents, radians, nested body tree'). This clearly distinguishes it from sibling tools like robosim_inspect_urdf or robosim_validate_urdf.

  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?

  No guidance is provided on when to use this tool versus alternatives (e.g., when to prefer it over robosim_sdf_to_urdf or robosim_step_to_urdf). There is no mention of prerequisites, limitations, or when not to use it.

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

• robosim_validate_urdfA
  3.5/5.0
  Behavior3/5

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

  Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is clear. The description adds context about what checks are performed and that results are returned by severity, but it lacks detail on the output format (e.g., fields in each issue) and does not mention performance or parsing 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?

  The description is concise, consisting of two sentences. The first sentence front-loads the purpose and what is checked, and the second briefly mentions the output format. No unnecessary words or details.

  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 simplicity (one parameter, clear annotations), the description is mostly complete. However, the output schema is missing, and the description only says 'issues by severity' without specifying the structure of each issue (e.g., severity level, message, location). This gap reduces completeness for an agent needing to parse the result.

  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 single parameter 'urdf' is well-described in the schema ('The URDF XML text.'). The description adds minimal additional meaning beyond stating it checks 'a URDF'. With 100% schema coverage, a baseline of 3 is appropriate.

  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 it checks a URDF for structural problems, listing specific areas like kinematic tree, inertia sanity, joint limits, and parser-divergence pitfalls. It distinguishes from siblings like 'inspect_urdf' by focusing on validation rather than general inspection.

  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?

  No guidance is provided on when to use this tool versus alternatives such as 'robosim_inspect_urdf'. The description does not specify when not to use it or mention any prerequisites or limitations.

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

• robosim_step_to_urdfA
  3.6/5.0
  Behavior4/5

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

  Discloses that solids are welded with fixed joints and that the first call loads a 7.6 MB OCCT kernel, adding valuable context beyond annotations (readOnlyHint, idempotentHint, destructiveHint). No contradictions.

  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?

  Two-sentence description is highly concise, front-loads the core purpose, and every sentence adds value without extraneous text.

  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?

  Covers input and computation but omits description of the tool's output or return value. No output schema is present, so the description should clarify how results are returned.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters2/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema description coverage is only 50%; description does not add parameter-specific information. Does not compensate for missing schema descriptions on filename and density.

  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?

  Explicitly states conversion from STEP/IGES CAD to URDF, with specific details about computing mass properties and joining solids. Clearly distinguishes from sibling conversion tools targeting other formats.

  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?

  No guidance on when to use this tool versus alternatives like sdf_to_urdf or xacro_to_urdf. Agent must infer based solely on input format.

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

• robosim_dh_to_urdfA
  3.8/5.0
  Behavior4/5

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

  The description adds behavioral info beyond annotations by stating it handles standard and modified conventions correctly, which is critical for domain-specific usage. Annotations already indicate safety (readOnly, idempotent, non-destructive).

  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 extremely concise (one short sentence) and front-loaded with the core purpose. Every word is necessary.

  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?

  For a domain-specific conversion tool, the description is minimal. It lacks details about output format, validation, error handling, and usage examples. With no output schema, more context would be beneficial.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters2/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  The description does not add any meaning beyond the input schema. With 50% schema description coverage, the description fails to clarify parameters like robotName and convention, which have no schema descriptions.

  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 action ('Generate') and the specific resource ('URDF joint chain from a Denavit-Hartenberg table'), and distinguishes it from sibling tools by focusing on DH tables and convention handling.

  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?

  While the description implies usage when DH parameters are available, it does not explicitly state when not to use it or mention alternatives among siblings (e.g., sdf_to_urdf, step_to_urdf).

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

• robosim_diff_ardupilot_paramsA
  3.8/5.0
  Behavior4/5

  Single sentence, front-loaded with core action, no wasted words. All information is relevant and efficiently presented.

  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?

  Covers main purpose, format detection, comparison method, and output categories. However, without an output schema, it omits details on return format and error conditions, leaving some gaps for a moderately complex tool.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters2/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Parameters 'before' and 'after' are self-explanatory but the description adds no additional semantics (e.g., file path vs content, expected format). With 0% schema coverage, the description should compensate but does not, leaving ambiguity.

  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 verb (compare), resource (ArduPilot .param files), and outputs (changed/added/removed parameters with float-epsilon equality). It distinguishes from sibling tools, which handle different operations.

  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 when to use (comparing param files) but offers no explicit guidance on when not to use or alternatives. Sibling tools are distinct, so context helps, but direct instruction is missing.

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

• robosim_sdf_to_urdfA
  3.8/5.0
  Behavior3/5

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

  Annotations already indicate readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is clear. The description adds the behavior of resolving pose frames, which is valuable context beyond annotations, but does not disclose any other behavioral traits.

  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 50% (parameters filename and content have descriptions). The description adds meaning by explaining that filename is used to detect format and content is lockfile contents. However, appName and appVersion are not explained, so the description does not fully compensate for the low coverage.

  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 produces a CycloneDX 1.6 SBOM from specific lockfiles, using a specific verb 'Produce' and resource 'SBOM', and distinguishes it from sibling tools that deal with robot model conversions.

  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 when to use (when you have a lockfile and need an SBOM) and lists acceptable lockfile formats, but does not provide explicit when-not-to-use or alternatives. The constraint 'Manifests without resolved versions are refused' is a limitation, not usage guidance.

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