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

With no annotations, the description carries the full burden for behavioral disclosure. It mentions that the operation returns a success/failure message, but it does not disclose potential side effects, permissions, or behavior when a document with the same name exists. For a mutation tool, this is insufficient.

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 structured with Args, Returns, and Examples, front-loading the purpose. It is slightly verbose for a one-parameter tool but every section adds value, and the example is helpful.

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?

The tool is simple with one parameter, and the description covers input, output, and example usage. An output schema exists (even if not shown), and the description already explains the return message. It is complete enough for an agent to invoke correctly.

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 schema has no description for the 'name' parameter (coverage 0%), but the description explicitly states 'The name of the document to create' and provides an example. This adds meaning beyond the schema, effectively compensating for the gap.

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 'Create a new document in FreeCAD', which is a specific verb and resource. It distinguishes itself from sibling tools like create_object or create_sketch by focusing on document-level creation, and the example reinforces the purpose.

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 provides no guidance on when to use this tool versus alternatives. It does not mention when not to use it or reference other tools. The example shows basic usage but lacks contextual guidance.

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

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

The description mentions returns a message and screenshot but lacks details on side effects, error conditions, or permission requirements. No annotations are provided to compensate.

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 well-structured with summary, Args, Returns, and Examples, but the examples are numerous and could be trimmed for conciseness while still being informative.

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 complexity and presence of output schema, the description covers parameters and examples adequately. It lacks details on error handling but is otherwise complete.

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?

Despite 0% schema description coverage, the description explains each parameter in Args and provides detailed examples showing usage of doc_name, obj_type, obj_name, analysis_name, and obj_properties, adding significant meaning beyond the schema.

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 'Create a new object in FreeCAD' and lists supported object types. It distinguishes from sibling tools like delete_object and edit_object.

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 provides when to use the tool (creating various objects) and gives extensive examples. However, it does not explicitly mention when not to use it or alternatives.

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

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

With no annotations provided, the description alone must disclose behavioral traits. It mentions the return value (message and screenshot) but does not state that deletion is permanent, irreversible, or whether it affects dependent objects or requires confirmation. This lack of safety/impact disclosure is significant for a destructive operation.

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 compact and well-structured: a one-sentence purpose, an Args list, and a Returns line. Every sentence serves a clear function with no redundancy.

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?

The tool is simple (2 required string parameters) and the description covers its purpose, arguments, and return value. However, it lacks any mention of prerequisites (e.g., document must exist), error behavior, or side effects beyond the obvious deletion, leaving some gaps for a destructive operation.

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 input schema offers no descriptions for the two parameters (0% coverage), but the description's Args section explicitly explains both doc_name and obj_name, adding meaning beyond the schema. It clarifies the document and object references, compensating for the schema gap.

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 uses a specific verb ('Delete') and resource ('an object in FreeCAD'), clearly distinguishing it from siblings like create_object, edit_object, and get_object. No other sibling tool has 'delete' in its name, so the purpose is unambiguous.

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 only states the action without providing explicit guidance on when to use this tool versus alternatives. It implies usage for deleting objects but offers no exclusions or alternative tool references. The context is clear from the purpose, but no explicit usage guidance is given.

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

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

With no annotations, the description carries full burden. It discloses the return value ('a message... and a screenshot') but omits critical behaviors: whether the object must exist, how obj_properties merges or replaces existing properties, and any side effects on the document. This is insufficient for a mutation tool.

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 short and front-loaded with the primary action and use case. The Args section repeats schema information, but the overall structure is clear and no sentences are wasted.

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 has 3 params with a nested object, no annotations, and an output schema (not detailed), the description does not provide enough context. It lacks error handling, prerequisites, and the structure of obj_properties. It also doesn't help choose between edit_object and the many sibling operations like pad, pocket, or fillet.

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?

Schema description coverage is 0%, so the description must compensate. The parameter descriptions merely restate the parameter names: 'doc_name: The name of the document to edit the object in' provides no additional detail about how obj_properties should be structured or what property names are valid. This adds minimal meaning beyond the schema.

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 'Edit an object in FreeCAD' and specifies a use case: 'used when the create_object tool cannot handle the object creation.' This differentiates it from create_object, though not from other editing tools.

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?

It explicitly names an alternative (create_object) and describes when to use this tool: 'when the create_object tool cannot handle the object creation.' However, it doesn't provide broader guidance on when not to use it or how it relates to other editing operations like pad or pocket.

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

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

With no annotations, the description carries full burden. It discloses that execution can be arbitrary, and returns success/failure, output, and a screenshot. However, it omits security implications, timeouts, or side effects.

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 extremely concise: two sentences plus an Args/Returns block. It front-loads the purpose, and every sentence serves a clear function without redundancy.

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 single parameter and existing output schema, the description explains the return values (message, output, screenshot) well. Minor gaps (no execution limits, environment details) prevent a 5.

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?

Schema coverage is 0%, but the description only restates the parameter name and type ('code: The Python code to execute'), adding no additional meaning like format, examples, or constraints.

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 states 'Execute arbitrary Python code in FreeCAD' with a specific verb ('execute') and resource ('Python code'), clearly distinguishing it from sibling tools like create_object or get_view.

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?

No guidance on when to use this tool versus alternatives, nor any exclusions or prerequisites. The description merely states what it does, leaving the agent to infer usage context.

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

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

No annotations are provided, so the description carries the burden. It mentions returning a screenshot, but does not explicitly state read-only behavior, side effects, permissions, or limitations. The description implicitly suggests read-only but is not fully transparent.

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 concise (3 lines), front-loads the purpose, and includes structured Args and Returns sections. Every sentence adds value without unnecessary words.

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 (2 required string params), the description sufficiently explains the return value (object and screenshot). With an output schema present, the description does not need to elaborate on return format further.

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?

With 0% schema description coverage, the description adds value by providing brief explanations for both parameters (doc_name: 'name of the document', obj_name: 'name of the object'). While not overly detailed, it compensates for the schema gap.

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 'Get an object from a document' with a specific verb and resource. It explains the purpose ('to see what you can check or edit') and distinguishes it from siblings like get_objects (plural) and create/delete/edit tools.

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 for inspection ('to see what you can check or edit'), but does not explicitly state when not to use it or name alternatives. Context signals and sibling list provide context, but the description lacks explicit guidance.

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

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

No annotations are provided, so the description must disclose behaviors. It correctly states the return values (list of objects and a screenshot), implying a read-only operation. However, it does not explicitly confirm no side effects or mention any permissions needed.

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 extremely concise: two sentences plus an Args/Returns section. Every sentence adds value, and the main purpose is front-loaded. No redundant 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 (one required parameter) and the presence of an output schema, the description is adequate. It covers the purpose, parameter, and returns. However, it could define what 'objects' means or mention that the screenshot is included for 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 input schema has 0% description coverage for the 'doc_name' parameter. The description adds a clear explanation: 'The name of the document to get the objects from.' This compensates for the schema gap and adds meaning.

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 action ('Get all objects') and the resource ('in a document'). It distinguishes from sibling tools like 'get_object' (singular) and other CRUD operations, making the purpose unambiguous.

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?

It provides a context for use ('to see what you can check or edit') and explicitly mentions the doc_name parameter. However, it does not compare with alternatives like 'get_view' or discuss when not to use it, leaving room for improvement.

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

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It simply states 'Get the list' without mentioning side effects, but since it has no parameters and likely returns a list, it is reasonable. However, it could explicitly state that it is a read-only operation.

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 a single, concise sentence with no redundant words. It is front-loaded and to the point.

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?

An output schema exists, so return values need not be detailed. However, the description could be slightly more informative about the scope of the parts library (e.g., which addon). But given the simplicity, it is mostly complete.

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?

There are zero parameters, and schema description coverage is 100%. According to guidelines, 0 params gives a baseline of 4. The description does not need to add parameter information, and it does not.

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 action 'Get' and the resource 'list of parts in the parts library addon'. It is specific and distinguishes from sibling tools like 'insert_part_from_library' which inserts rather than reads.

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?

No guidance is provided on when to use this tool versus alternatives. It does not mention that it is a read-only operation or that it retrieves the entire list without filtering. The implied usage is that it lists parts, but there are no exclusions or context.

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

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

With no annotations, the description carries the behavioral disclosure burden. It only states 'Get a screenshot' but does not explain how the screenshot is returned (image data, file path, base64), whether the view can be changed, or if the operation is idempotent. The return value is vague.

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 short and front-loaded with the purpose. The args and returns sections are structured. However, listing all enum values is somewhat redundant with the schema, but not excessive.

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?

The tool has a simple parameter and an output schema (likely defining the screenshot format), but the description omits details about the output format and any prerequisites. It is insufficient for an agent to fully understand the tool's usage without additional 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 description repeats the enum list from the schema without adding meaning (e.g., explaining what each view orientation is, like 'Isometric' vs 'Front'). Since schema description coverage is 0%, the description could have compensated by describing the views, but it did not.

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 gets a screenshot of the active view and lists the available views. It distinguishes itself from sibling tools like get_object or get_objects by specifying it captures a visual screenshot rather than data objects.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., when a screenshot is needed vs. getting object data). It does not mention prerequisites like whether a view must be active or what constitutes the 'active view.'

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

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

With no annotations, the description carries full responsibility for disclosing behavioral traits. It only states that it returns a success/failure message and a screenshot. It does not mention whether it modifies the current document, requires an active document, or has any side effects. This is insufficient for a mutation tool.

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 extremely concise and well-structured. It opens with a one-sentence purpose, then uses clear 'Args' and 'Returns' sections. Every sentence serves a purpose, and there is no wasted text.

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 low complexity (one parameter) and the presence of an output schema, the description is somewhat adequate. However, it lacks usage context and any safety or side-effect information, especially since annotations are absent. For a simple insert operation, it covers the basics but leaves gaps.

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 schema description coverage is 0%, so the description must compensate. It provides one line: 'relative_path: The relative path of the part to insert.' This adds basic meaning over the schema's bare title 'Relative Path', but it is still minimal and does not explain the path's base directory or format.

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 action with a specific verb ('Insert') and resource ('a part from the parts library addon'). This distinguishes it from siblings like 'get_parts_list' (which lists parts) and 'create_object' (which creates from scratch).

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?

No guidance is given on when to use this tool versus alternatives. It does not mention any prerequisites, contexts, or specific scenarios where this tool should be preferred. The sibling list includes related tools like 'instantiate_family' and 'get_parts_list', but the description offers no differentiation.

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