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

No annotations provided, so description carries full burden. It only states the core action but omits critical behavioral details: whether existing fills are replaced, what happens if the variable doesn't exist, side effects, or required permissions.

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?

Description is a single, efficient sentence that conveys the core purpose without extraneous words. It is front-loaded and wastes no space.

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 params, no output schema), the description provides the essential purpose. However, missing behavioral context (e.g., fill replacement behavior, variable existence handling) limits completeness for a fully informed agent.

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 100% with descriptions for both parameters. The description adds no additional meaning beyond what the schema already provides, so baseline score of 3 applies.

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?

Description clearly states the action: bind a Figma variable to a node's fill color. The verb 'bind' and resource 'variable to fill' are specific, and it distinguishes from sibling tool bind_variable_to_stroke by specifying 'fill' vs 'stroke'.

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?

Description implies usage (when you want to set fill via variable) but provides no explicit guidance on when to use this vs alternatives like set_fill_color, nor any prerequisites or when-not-to-use.

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, and the description does not disclose behavioral traits such as whether existing bindings are replaced, what happens if the node lacks a stroke, or any side effects. This is inadequate 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 a single sentence with no fluff. It is concise and front-loaded with the key action, though it could benefit from slightly more structure or additional context.

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 lack of output schema, minimal annotations, and only two parameters, the description is too brief. It does not explain the return value, behavior when binding fails, or any constraints on the variable.

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 100%, so both parameters are already documented in the schema. The description does not add additional meaning beyond the schema, resulting in a baseline score of 3.

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 'Bind', the resource 'Figma variable', and the target 'node's stroke color'. It is specific and differentiates from the sibling tool 'bind_variable_to_fill'.

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 does not provide guidance on when to use this tool versus alternatives, nor does it mention any prerequisites or exclusions. It simply states the action without 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 provided, the description carries the full burden of behavioral disclosure. 'Clone an existing node' implies a mutating operation, but it does not clarify whether the original node is preserved, where the clone is inserted, how x and y affect positioning, or what side effects occur. This is a significant gap 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 a single concise sentence with no wasted words, and the key action is front-loaded. However, it is so brief that it sacrifices behavioral and contextual detail, making it concise but underinformative.

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 no annotations, no output schema, and a description that only states the basic action. It does not explain the resulting node's placement, relationship to the original, return value, or whether x and y are optional/required together. This is incomplete for an agent expected to invoke the tool correctly in a broader design workflow.

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 100% description coverage, so the schema already explains nodeId, x, and y. The description adds no extra parameter semantics beyond confirming the nodeId refers to an existing node. Baseline 3 is appropriate because the schema handles the burden.

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 a specific verb ('Clone') and a clear resource ('an existing node in Figma'), which makes the core purpose understandable. It does not explicitly differentiate from siblings like create_rectangle or move_node, but the verb 'clone' semantically implies duplication of an existing node, distinguishing it from creation or transformation 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 provides no guidance on when to use this tool versus alternatives, nor does it mention when not to use it. An agent must infer from the name and description that this is for duplicating an existing node, and there is no comparison with sibling operations such as create_frame or create_component_instance.

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, so description must cover behavioral traits. Does not mention side effects (original node status), permissions, idempotency, or return value.

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?

Two short sentences, no fluff, essential information only.

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?

Adequate for a simple one-param tool with constraint, but missing behavioral details expected for a mutation with no annotations or output schema.

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 covers nodeId with simple description. The tool description adds the critical constraint, providing 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?

Explicitly states conversion of frame/node to component, with a clear constraint. Distinguishes from siblings like create_component_instance.

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?

Includes a key when-not-to-use condition (node cannot already be a component or inside one). Lacks explicit alternatives or broader 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 provided, so the description carries full burden. It fails to disclose that this is a mutation operation, permission requirements, or how positioning works relative to the parent. The brief text omits important behavioral traits.

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 (one sentence) but too vague to be informative. It lacks substance despite being short, so it does not earn a higher score.

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 no output schema and no annotations, the description is insufficient. It does not explain return values, error handling, or how the instance is created in the document structure. With 5 parameters, more detail is needed.

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 descriptions cover 100% of parameters, so the tool description adds no extra meaning. Baseline 3 is appropriate; the description does not clarify relationships like mutual exclusivity of componentId and componentKey.

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 'create' and the resource 'instance of a component', and 'in Figma' specifies the domain. However, it does not differentiate from sibling tools like 'create_component_from_node' or 'clone_node', which could cause confusion.

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, such as when to use componentId vs componentKey, or prerequisites like an existing component. The description lacks context on appropriate usage scenarios.

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 full burden of behavioral disclosure. It only says connections are created with the default connector style; it does not state whether creation is additive, whether duplicates are allowed, how invalid node IDs are handled, or whether the default style can be overridden per connection. The optional text field in the schema hints at per-connection text, but runtime behavior is not disclosed.

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 tightly worded sentence that front-loads the core action and adds the relevant style qualifier. It contains no filler, restates nothing from the schema, and every word earns its place.

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 and complete input schema, the description is serviceable for basic invocation. However, with no output schema and no annotations, it omits useful behavioral context such as the dependency on set_default_connector for style, behavior on invalid node references, and what the call returns. It is minimally adequate but not fully 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?

Schema description coverage is 100%, so the schema already documents startNodeId, endNodeId, and text clearly. The description adds little beyond confirming the semantic relation of 'nodes' to the IDs. This meets the baseline for schema-covered parameters but does not enhance parameter understanding further.

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 a specific action ('Create'), a specific resource ('connections between nodes'), and a qualifier ('using the default connector style') that distinguishes it from related style-configuration tools like set_default_connector. It is unambiguous about what the tool does without restating the tool name.

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 explicit guidance is given about when to use this tool versus alternatives or when not to use it. The phrase 'default connector style' implies a relationship with set_default_connector, but that relationship is never named or explained. The agent gets no help choosing between this and related connection/style tools.

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 full burden of behavioral disclosure, but it only restates the core creation action. It does not mention where the frame is created (e.g., current page vs. parentId), whether it becomes selected, what defaults apply, or any side effects on the document tree, which are important for a mutation tool with no safety hints.

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, front-loaded sentence with no redundancy. It is appropriately concise, though it could include a bit more context without becoming verbose.

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?

Despite a detailed 20-parameter schema, the one-sentence description lacks high-level context such as where the frame is inserted, how it interacts with the current selection, and what the tool returns. With no output schema and no annotations, an agent needs more behavioral context to invoke this tool correctly, especially given the complex auto-layout parameters.

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 100%, so all 20 parameters are fully documented in the schema. The tool description itself adds no parameter-specific information, but the high schema coverage means the baseline of 3 is appropriate.

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 a clear action ('Create') and a specific resource ('a new frame in Figma'), which distinguishes it by resource from sibling creation tools like create_rectangle and create_text. It is not a tautology and conveys the object and environment, though it does not explicitly contrast with the conceptually similar create_section.

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 over alternatives like create_section or create_rectangle. No context about scenarios, prerequisites, or exclusions is given, leaving the agent to infer usage solely from the tool name.

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 must disclose behavioral traits. It only states the creation action without mentioning side effects (e.g., does it switch to the new page based on 'setCurrent'? what happens if the page name already exists?). The schema covers 'setCurrent' but the description does not clarify behavior.

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, focused sentence that effectively communicates the tool's core action. No unnecessary words, and the most critical information is front-loaded.

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 no annotations, no output schema, and two parameters with full schema coverage, the description is too minimal. It does not explain return values, error scenarios, asynchronous behavior, or required permissions, leaving the agent with an incomplete picture.

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 100%, so baseline is 3. The description does not add any information beyond the schema; it does not explain the parameters or their usage. No credit added.

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 ('Create a new page') and the resource ('in the Figma document'). It is specific and unambiguous. However, it does not distinguish from sibling tools like 'switch_page' or 'get_pages', which is acceptable but prevents a perfect score.

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 to create a new page vs. switching to an existing one). The agent is left to infer usage from the tool name alone.

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 full burden of behavioral disclosure, but it only repeats the basic action. It does not mention default parenting behavior, coordinate system, units, selection handling, or side effects beyond the creation itself.

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 sentence with no wasted words. It is front-loaded and immediately communicates the core action.

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?

For a tool with 6 parameters, no output schema, and no annotations, this description is too minimal. It omits important context such as what happens when parentId is omitted, what coordinate space x/y refer to, and what the tool returns after creation.

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 provides descriptions for all 6 parameters, so the schema fully documents semantics. The description adds no additional parameter-level meaning, making the baseline score of 3 appropriate.

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 'Create a new rectangle in Figma' states a specific verb and resource, clearly identifying the operation. It does not explicitly contrast with sibling creation tools like create_frame or create_text, but the resource type 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?

No usage guidance is provided. The description does not explain when to choose create_rectangle over alternatives such as create_frame or create_section, nor does it mention any preconditions or context in which this tool should be used.

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 full burden of behavioral disclosure. It states that a new element is created but does not mention side effects, whether the node is placed on the current page or requires a parentId, how naming works, or whether the operation is reversible.

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, front-loaded sentence with no redundant words. It is concise and easy to parse, though slightly underspecified for the number of optional parameters and the lack of added behavioral context.

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 8 parameters, a nested fontColor object, no output schema, and no annotations, the one-sentence description is not complete enough. It does not explain how parentId affects placement, what the default behavior is, what the tool returns, or how the new text node relates to the current selection or page.

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 100%, so every parameter already has a description in the schema. The tool description itself adds no parameter-level meaning, which is acceptable given the schema's coverage, but it does not go beyond the baseline.

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 ('Create') and the resource ('a new text element in Figma'). It is specific enough to distinguish from create_rectangle and create_frame, though it does not explicitly call out sibling differentiation.

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?

There is no guidance about when to use this tool versus alternatives such as set_text_content, create_rectangle, or create_frame. The description provides no context about preconditions, suitable scenarios, or when another sibling tool would be more appropriate.

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 fails to disclose behavioral traits such as potential conflicts (e.g., overwriting existing collections), required permissions, or side effects beyond the basic creation 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, well-structured sentence that conveys the essential information without any wasted 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 complexity (3 params, nested arrays) and no output schema, the description is adequate but lacks detail on return values, error handling, or conflict behavior. It covers the core purpose but not the full 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?

Schema description coverage is 100%, so baseline is 3. The description adds marginal value by mentioning 'COLOR, FLOAT, STRING, and BOOLEAN types' and giving a modes example, but this mostly repeats schema info.

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 ('Create'), the resource ('a Figma variable collection with variables'), and the supported types and modes. It distinguishes from sibling tools that apply or bind variables.

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 explicit guidance on when to use vs. alternatives is provided. The description only lists capabilities, leaving the agent to infer that this tool is for creating variable structures, not applying them.

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 full burden of behavioral disclosure. It states the operation is a deletion, which implies destructiveness, but it does not mention irreversibility, permission requirements, cascade effects on child nodes, or failure behavior when one node ID is invalid.

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, front-loaded sentence with no redundant words. It efficiently communicates the tool's core purpose without unnecessary elaboration.

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?

For a destructive batch operation with no annotations and no output schema, the description is too thin. An agent still lacks essential operational context such as whether the deletion is permanent, what happens if one node ID is invalid, and whether all deleted nodes must belong to the same document or page.

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 100%, so the parameter nodeIds is already documented as an array of node IDs to delete. The description adds only the notion of batch processing ('multiple nodes...at once'), which adds minimal semantic value 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 the verb 'Delete' and the resource 'multiple nodes from Figma', and distinguishes this tool from its sibling delete_node by emphasizing batch deletion. This gives an agent a precise understanding of the tool's scope.

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 phrase 'at once' implies this tool is for batch deletion rather than single-node deletion, but it does not explicitly state when to prefer it over delete_node or when not to use it. The usage context is implied, not spelled out.

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 bears the full burden of behavioral disclosure. It only states the basic delete action and omits critical traits such as irreversibility, whether child nodes are deleted, or any side effects. For a destructive operation, this is a significant transparency gap.

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, direct sentence with no filler words. It is front-loaded with the action and resource, but it is so minimal that it omits useful behavioral context; still, as far as structure and brevity, it is clean.

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?

For a destructive tool with no annotations and no output schema, the description is incomplete. It fails to mention the irreversible nature of the operation, whether children are affected, or how this tool differs from 'delete_multiple_nodes'. An agent is left without key information for safe invocation.

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 100% and the 'nodeId' parameter is clearly described as 'The ID of the node to delete'. The tool description does not add extra parameter semantics beyond the schema but does not need to, so the baseline 3 applies.

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 a specific verb ('Delete'), a resource ('node'), and a context ('from Figma'), making the core action clear. It does not explicitly differentiate from the sibling tool 'delete_multiple_nodes', so the specificity is slightly incomplete, but the singular phrasing and tool name carry that distinction.

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 about when to use this tool versus alternatives such as 'delete_multiple_nodes'. The description gives no context for choosing between single and batch deletion, nor any exclusions or prerequisites.

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 must disclose behavioral traits. It mentions sublayer text becomes modifiable, but does not indicate if detaching is destructive (breaks library link), reversible, or affects the original component.

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?

Two concise sentences with no redundant information. Front-loaded with the main action and outcome.

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?

For a single-parameter tool with no output schema, the description covers the basic effect but lacks details on side effects, errors, or return value, leaving some 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?

Schema coverage is 100% with a single parameter 'nodeId' described as 'The instance node ID to detach'. The description adds no extra context beyond the schema, earning the baseline score of 3.

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 verb 'detach', the resource 'library instance', and the outcome 'into an editable frame' with 'sublayer text becomes modifiable'. This distinguishes it well from sibling tools like create_component_instance or set_instance_properties.

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 the tool is for making library instances editable, but does not explicitly state when to avoid using it, prerequisites (e.g., node must be a valid instance), 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 carries the full burden of behavioral disclosure, but it only restates the tool name without adding behavioral context. It does not state whether the operation is read-only, what response format to expect, what limits exist, or how unsupported nodes are handled.

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 one short, front-loaded sentence with no wasted words. It is easy to parse, though the brevity sacrifices useful behavioral context.

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 no annotations and no output schema, so the description is the only place to communicate return behavior, side effects, and constraints. It provides none of that, leaving an agent uncertain about what happens after invocation beyond the parameter contract.

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 100%, so the schema already documents all three parameters adequately. The description adds no additional meaning to nodeId, scale, or format beyond what the schema provides, which aligns with the baseline of 3.

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 a specific verb ('Export'), resource ('a node'), and result ('as an image'), making the core purpose clear. It is distinct from sibling tools, though it does not explicitly differentiate itself from alternatives by name.

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?

There is no guidance about when to use this tool versus siblings, no prerequisites, and no mention of exclusions or alternatives. Usage is only implied by the tool's purpose, not explained.

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 full burden of behavioral disclosure. It communicates a read operation but does not clarify how 'current document' works when nodeId is required, what happens when there are no annotations, whether permissions are needed, or what the response shape looks like.

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 filler or redundant phrasing. It loses a point because 'current document or specific node' is compact but ambiguous, especially in light of the required nodeId parameter.

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?

For a tool with no output schema and no annotations, the description is not complete enough for confident invocation. The unresolved 'current document' mode versus the required nodeId is a significant gap, and the description does not state the return behavior or any special values needed for document-level retrieval.

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 100%, so the schema already documents nodeId and includeCategories. The description adds only the high-level notion of 'current document or specific node' and does not explain behave includeCategories affects the result beyond the schema's own wording.

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 ('Get') and names the resource ('annotations'), with a clear read-vs-write contrast against siblings like set_annotation and set_multiple_annotations. However, the phrase 'current document or specific node' is ambiguous because nodeId is required in the schema, making the document-level mode unclear.

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?

Usage is implied by the tool's read-only name and by the presence of set_annotation/set_multiple_annotations as siblings, so an agent can infer it is for reading annotations. But there is no explicit when-to-use guidance, no exclusions, and no mention of when to choose this over get_node_info or get_selection.

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 present, so the description must carry the burden of disclosing behavior. It only states 'get detailed information', which implies a read, but does not explain what details are returned, permissions needed, or any limitations. This is under-informative for an agent.

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?

One concise, front-loaded sentence with no unnecessary words. Every word contributes to the purpose.

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, but with no output schema or annotations, the description should clarify what 'detailed information' includes. The current text is vague and leaves the agent guessing about the response structure. It is minimally acceptable but not 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?

The tool has zero parameters, so schema coverage is trivially 100%. The description does not need to add parameter semantics, and the baseline of 4 applies.

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?

Uses a specific verb ('get') and resource ('document') with scope ('current Figma document'). Clearly distinguishes from siblings like get_node_info and get_selection.

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?

Implies usage for document-level information through the description, but does not explicitly mention when to use it versus alternatives such as get_node_info or read_my_design. No exclusions or contextual guidance provided.

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 provided; description carries full burden. It describes a read operation, but does not explicitly state read-only, no side effects, or any required permissions. Adequate but not rich.

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?

Single sentence, no redundancy, front-loaded with action and resource. Every word earns its place.

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?

For a simple get tool with one parameter and no output schema, the description is fairly complete. Lacks usage guidelines and behavioral transparency, but still functional.

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 100% with parameter description 'The instance node ID'. Description does not add additional meaning beyond schema, so baseline 3 applies.

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?

Description specifies verb 'Get', resource 'instance node', and what is retrieved ('mainComponent key and info'). Clearly distinguishes from sibling tools like get_node_info or get_instance_overrides.

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 over alternatives (e.g., get_node_info, get_instance_overrides). For a tool with many siblings, this omission reduces an agent's ability to select the correct tool.

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 behavioral burden. It communicates that this is a retrieval operation and that the overrides are reusable, but it does not explicitly state read-only behavior, side effects, or what happens when no instance is selected—though the schema covers the selection fallback.

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 two concise sentences with no filler. The primary action is front-loaded, and the second sentence provides valuable purpose context without unnecessary length.

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?

For a tool with one optional parameter and no output schema, the description plus schema provides enough information to call it correctly: what it returns, where it gets data from, and how the result can be used. It does not detail the override data structure, but the stated purpose is sufficient for this simple tool.

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 only parameter, nodeId, has 100% schema description coverage, including its optionality and fallback to the current selection. The description adds contextual meaning about how the overrides can be used, but does not need to repeat parameter-level details.

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 action, 'Get all override properties', and identifies the exact resource, 'a selected component instance'. This clearly separates it from the sibling set_instance_overrides, which performs the inverse write operation.

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 explains that the retrieved overrides can be applied to other instances, giving a clear use case for the tool. It does not explicitly name alternatives or exclusion conditions, but the intent is clear enough for an agent to choose this over set_instance_overrides.

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 fully disclose behavior. It correctly indicates a read-only operation ('list'), but doesn't mention pagination, permissions, or what happens if no collections exist. For a simple list tool, this is acceptable but not thorough.

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?

A single, front-loaded sentence that conveys the entire purpose with no unnecessary words. Every part earns its place.

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?

For a parameterless tool with no output schema, the description sufficiently explains what is listed. It could briefly mention that the result is an array of variable collections, but that is implied. No critical 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 input schema has zero parameters (100% coverage). The description adds value by clarifying the scope ('from enabled team/community libraries'), which would otherwise be ambiguous. Baseline for 0 params is 4, and this description meets it.

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 verb 'list' and resource 'library variable collections', specifying they come from enabled team/community libraries. This distinguishes it from sibling tools like get_library_components (lists components) and get_local_components.

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 the tool is for retrieving library variable collections but provides no explicit guidance on when to use it versus alternatives or when not to use it. No context about prerequisites or limitations 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?

No annotations are provided, and the description does not disclose behavioral traits such as read-only nature, pagination, error handling, or performance implications. Given that annotations are missing, the description carries the full burden but fails to inform the agent about these aspects.

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 sentence that is clear, direct, and front-loaded. It contains no unnecessary words or 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?

The tool is simple with one required parameter. The description is sufficient for listing components, but it does not explain the return format (e.g., list of component IDs or details). With no output schema, this information would be helpful for the agent to interpret results. Adequate but could be improved.

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 covers the single parameter with a description that matches the tool's description. The schema coverage is 100%, so the parameter semantics are adequately defined. The tool's description adds no extra meaning beyond restating the schema, resulting in a baseline score of 3.

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 ('List') and the resource ('components in a specific library collection'), with the identification method ('by collection key or name'). It effectively distinguishes from sibling tools like get_local_components and get_library_collections.

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 when to use the tool (when you have a library collection key or name to list its components), but it does not explicitly state when not to use it or provide alternatives. For example, it could note that get_local_components lists local components instead. This is adequate but not thorough.

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 bears full responsibility for disclosing behavior. It states the scope ('local components' and 'from the Figma document') but does not describe return format, pagination, or what constitutes 'local' versus imported components.

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 irrelevant details, making it highly efficient.

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?

For a zero-parameter getter with no output schema, the description is largely adequate, specifying the resource and scope. However, it omits any detail about the return value or whether components from all pages are included, though 'from the Figma document' implies full document scope.

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 tool has zero parameters, so the input schema is empty. The description appropriately avoids parameter explanation; per the baseline for zero-parameter tools, a score of 4 is appropriate.

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 retrieves all local components from the Figma document. The verb 'get' and specific resource 'local components' distinguish it from sibling tools like get_styles or get_document_info.

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 offers no guidance on when to use this tool versus alternatives like get_styles or create_component_instance. There is no mention of prerequisites, intended use cases, or exclusions.

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 full disclosure burden. It only says 'get detailed information'; it does not disclose what fields or depth of data are returned, whether authentication/access is required, or how invalid node IDs are handled. The verb 'get' implies read-only, but no additional behavioral detail is given.

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?

A single, front-loaded sentence with no filler. Every word contributes to stating the action and the target resource.

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?

For a one-parameter read tool, the description is minimally sufficient to make a call, but it does not specify what 'detailed information' contains and does not route the agent away from get_nodes_info. With no output schema and no annotations, that leaves a real gap in selecting and interpreting the call.

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 already documents nodeId with 100% coverage, so the baseline is 3. The description adds 'specific node' but no extra meaning about the ID format, nesting, or addressability of nodes.

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 a clear action and resource: get detailed information about a specific node in Figma. It is not as strong as it could be because it does not explicitly contrast itself with the plural sibling get_nodes_info or with get_document_info, leaving the distinction to inference.

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?

There is no guidance about when to choose this tool over get_nodes_info, get_selection, or get_document_info, and no mention of prerequisites or cases where it should not be used. The intended usage is only implicit in the verb 'get'.

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 carries the full burden of behavioral disclosure. It implies a read-only operation but does not reveal what 'detailed information' contains, whether there are limits on the number of node IDs, how errors are handled, or what the response format looks like. This is a minimal, somewhat tautological statement.

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, short sentence with no redundant filler. It is front-loaded with the core action and resource. While it could include more useful detail, it does not waste words, so conciseness is good.

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 there is no output schema, the description should clarify what information is returned for the requested nodes, but it does not. It also omits any mention of limits, error behavior, or relationship to sibling tools. For a tool with one parameter, the definition is underspecified and leaves important operational context unknown.

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 complete coverage (100%) for the single parameter, and the description adds no additional semantic detail beyond what the schema already says. The baseline of 3 applies because the schema documents the parameter adequately.

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 a clear verb ('Get') and resource ('detailed information about multiple nodes in Figma'), which distinguishes it from singular sibling get_node_info by indicating multiplicity. However, 'detailed information' is vague about what exactly is returned, and it does not explicitly reference or contrast with similar 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?

No guidance is given about when to use this tool versus siblings like get_node_info, get_selection, or get_document_info. The description does not mention any conditions, exclusions, or alternatives, leaving the agent to infer usage solely from the tool name and parameter.

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?

Description implies read-only operation but does not explicitly state behavioral traits such as idempotency, error scenarios, or response structure. With no annotations, additional clarity would help.

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?

Single, focused sentence with no extraneous wording. Front-loaded and efficient.

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?

Simple tool with no parameters and no output schema. Description adequately states purpose, but lacks details on output format or edge cases. Acceptable for its simplicity.

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?

No parameters exist and schema coverage is 100%, so baseline 4 applies. Description adds no parameter info because none are required.

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 pages' and the context 'current Figma document', distinct from siblings like create_page or switch_page.

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?

Implied usage: use to retrieve pages. No explicit when-to-use or when-not-to-use, nor mention of alternatives like create_page for creation.

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 full burden. It indicates a read operation but does not disclose return format or any potential side effects. For a simple version check, this is minimally adequate but not rich.

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 sentence of 12 words, conveying purpose and usage without redundancy. Every word earns its place.

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 zero parameters and no output schema, the description covers the essential purpose. However, it could mention the expected return value format (e.g., version string) to be fully 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 no parameters, and schema coverage is 100%. Per guidelines, baseline is 4. The description does not need to add parameter info, so this score is appropriate.

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 verb 'Get' and the resource 'Figma plugin version', with explicit purpose 'to verify it is up-to-date'. This distinguishes it from all sibling tools, none of which mention plugin version.

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 gives no guidance on when to use this tool versus alternatives, but given it is a simple version getter with no parameters, the context is adequate. No exclusions or alternatives mentioned.

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 burden. It conveys a read-only getter and adds a valuable behavioral constraint (output must be transformed before use), but it does not disclose return format, error behavior, or permissions. Some behavior is disclosed, but gaps remain.

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 two sentences, front-loaded with the core action and followed by a necessary cross-tool pipeline warning. No repeated schema content; the critical instruction earns its place despite its emphasis.

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?

For a one-parameter tool, the definition is usable: it states what to do and what to do with the result. However, with no output schema and no annotations, the absence of any description of the returned reaction data leaves an agent dependent on the named strategy prompt for interpretation.

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 100% and the single nodeIds parameter is already documented as an array of node IDs. The description's 'from multiple nodes' reinforces the parameter but adds no new format or constraint details, so baseline 3 is appropriate.

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 names a specific resource ('Figma Prototyping Reactions') and the scope ('from multiple nodes'), which clearly distinguishes it from sibling getters like get_node_info or get_selection. The verb 'Get' plus the unique resource makes the tool's function immediately identifiable.

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 CRITICAL instruction explicitly states that the output must be processed by the reaction_to_connector_strategy prompt and passed to create_connections, giving an unambiguous downstream workflow. It does not name alternative tools or exclusion criteria, but none are needed for this niche getter, so the usage context is clear.

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 must carry the full burden of behavioral disclosure. 'Get information' implies read-only, but it doesn't specify the return format, behavior with an empty selection, or any other edge cases. This is minimal for a tool with no annotation support.

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 well-structured sentence, front-loaded with the verb and subject, and contains no extraneous words. It is as concise as possible while conveying the core purpose.

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, but the lack of output schema and the vagueness of 'information' leaves significant gaps. The description does not explain what the returned data looks like, how to handle an empty selection, or any prerequisites, making it incomplete for an agent to fully rely on.

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 zero parameters, so schema coverage is effectively 100%. The description adds no parameter semantics, but with no parameters the baseline of 4 is appropriate; there is nothing to explain.

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 the specific verb 'Get' and the resource 'current selection' in Figma, clearly distinguishing it from sibling tools like set_selections (which sets selection) and get_node_info (which targets specific nodes). It is concise and 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 provides no guidance on when to use this tool versus alternatives. It doesn't mention exclusions or alternatives, leaving the agent to infer usage context from sibling names rather than explicit direction.

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 itself must convey behavior. It implies a read-only operation via 'Get', but it does not disclose what constitutes a 'style' (e.g., paint vs text styles) or any error conditions. This is minimal but not misleading.

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 sentence with no filler, front-loading the action and resource. 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.

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

While the tool is simple and the description captures the core action, it omits details about the output format or whether library styles are included. Given no output schema, a bit more context would improve completeness, but the low complexity prevents a lower score.

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 is empty, so there are no parameters to explain. The description correctly focuses on the tool's action, and with zero parameters, no further semantic detail is necessary.

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 verb 'Get' and the resource 'all styles' scoped to 'the current Figma document', which distinguishes it from sibling tools that create, apply, or rename styles. There is no ambiguity about what the tool does.

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 explicit guidance on when to choose this tool over alternatives like create_paint_style or apply_paint_style. The usage is implied by the name and semantics, but there is no mention of prerequisites or exclusions, so the agent must infer.

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 but only states the basic action. It does not disclose permissions, effects on existing instances, or other behavioral traits.

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?

Single sentence, no redundancy, efficiently conveys the tool's purpose.

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?

For a tool with 4 params and no output schema, the description is minimally complete but lacks details like parentId behavior or instance creation specifics.

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 100%, so the description adds no extra meaning beyond the schema. Baseline 3 is appropriate.

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 (import), resource (component from library), and outcome (create instance on current page). It effectively distinguishes from siblings like import_component_set_by_key, which imports a set.

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 that a key from get_library_components is needed, but does not explicitly state when to use this tool vs alternatives, nor does it provide when-not-to-use 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 carry the full burden of disclosing behavioral traits. It only states the action without explaining side effects, prerequisites (e.g., library access), error handling, or whether the import is a copy or reference. 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 a single, clear sentence with no unnecessary words. It is front-loaded and efficient.

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, but the description lacks context about post-import behavior, prerequisites, and potential errors. Given the presence of sibling import tools, more context would improve completeness. Score 3 as minimally adequate.

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 100% with the 'key' parameter described as 'The component set key'. The description adds no additional meaning beyond what the schema provides, meeting the baseline of 3.

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 verb 'Import', the resource 'component set (with variants)', and the means 'from a library by its key'. It distinguishes from sibling tools like 'import_component_by_key' and 'import_style_by_key' by specifying 'component set' rather than single component or style.

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. The description does not mention that this is for component sets with variants, while 'import_component_by_key' is for single components. No explicit when-to-use or when-not-to-use information.

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 full behavioral disclosure burden. It only states the basic import action, omitting details like error handling (e.g., key not found), side effects, permissions, or what happens if the style already exists.

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, front-loaded sentence that contains essential information without any fluff. Every word contributes to understanding.

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?

For a simple tool with one parameter and no output schema, the description includes the style types which adds context. However, it lacks information about behavior (e.g., success/failure responses, idempotency) that would make it 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?

Schema coverage is 100% (the 'key' parameter has a description). The description adds 'by its key' but does not provide additional meaning beyond what the schema already conveys. Baseline 3 is appropriate.

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 (import), the resource (a style), specifies the types (color, text, effect, grid), and the method (by its key). It effectively distinguishes itself from sibling tools like import_component_by_key.

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 importing styles by key but provides no explicit guidance on when to use this tool versus alternatives (e.g., import_component_by_key) 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.

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 explaining side effects, permissions, idempotency, or state changes. The description only says 'Join a specific channel' and gives no indication of what happens when joining, whether it is reversible, whether authentication is required, or what observable effects occur.

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 sentence with no redundant clauses, making it concise and easy to parse. The phrase 'specific' is slightly filler-like, but overall the structure is clean and front-loaded with the action.

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 one optional parameter, no output schema, no annotations, and a tool that is disjoint from the many sibling node/manipulation tools, the description is too thin for an agent to understand when or how to call it. It does not explain what channels exist, where the channel name comes from, what a successful join looks like, or what conditions cause failure.

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 100% with a parameter description ('The name of the channel to join'), so the schema already handles the basic meaning. The tool description adds no extra information about channel format, naming rules, valid values, or how to discover available channels. Baseline 3 is appropriate since the schema does the heavy lifting.

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 a concrete action ('Join a specific channel') and identifies the resource (a channel), but the purpose is vague: 'to communicate with Figma' does not explain what joining the channel accomplishes, what a channel is in this context, or how this relates to the other Figma tools. It is not a tautology, but it lacks enough specificity to be fully clear.

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, what problem it solves, or which situations warrant joining a channel. It does not mention any prerequisites, exclusions, or alternatives. An agent has no context to decide when this tool is the right choice.

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 full burden of behavioral disclosure. It only restates the move action and does not explain whether the move is absolute or relative, what coordinate system is used, whether the node must already exist, how the move interacts with parent/child relationships, or whether the operation is reversible.

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, direct sentence with no filler or redundant detail, and the core action is front-loaded. It loses one point because the text is so minimal that it fails to include contextual guidance that would make the conciseness genuinely useful.

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 and all three required parameters are fully documented in the schema, so the one-line description is minimally viable. However, with no annotations, no output schema, and sibling tools that overlap semantically, the description is not complete enough: it leaves the meaning of 'position' ambiguous and gives no usage or side-effect information.

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 100%, and the schema already defines nodeId, x, and y with clear descriptions. The tool description adds no additional parameter meaning, but it does not need to compensate because the schema already provides the essential semantics. Baseline 3 is appropriate.

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 and resource — 'Move a node to a new position in Figma' — and the x/y parameters make it clear this is a coordinate move. It is not fully a 5 because 'new position' could be confused with moving a node in the hierarchy, especially given the sibling tool set_parent.

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?

There is no guidance on when to use this tool versus alternatives such as set_parent, resize_node, or clone_node. The description does not mention exclusions, prerequisites, or any decision context, so the agent gets no help selecting between overlapping siblings.

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 carries the full burden. The name and verb 'Get' imply a read-only operation, but the description does not disclose what happens when there is no selection, whether multiple nodes are returned, or the exact structure of the returned 'node details'. It remains somewhat vague about the tool's behavior beyond the basic read action.

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, front-loaded sentence that immediately states the action and subject. It is concise with no wasted words or redundant phrasing.

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 no parameters and no output schema, so the description is the only source for return expectations. It says 'detailed information' and 'all node details' but does not enumerate the details or mention edge cases like empty selection. While the tool is simple, the description could be more precise about the returned content and error behavior.

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 is empty with zero parameters, so there are no parameter semantics to explain. The description does not need to compensate for undocumented parameters, and the baseline for 0 parameters is 4, which is appropriate here.

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 verb 'Get' and the resource 'detailed information about the current selection in Figma', and adds 'including all node details' which specifies the scope. This distinguishes it from sibling tools like 'get_selection' which likely returns only the selection IDs, and 'get_node_info' which targets specific nodes rather than the current selection.

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 when the current selection's details are needed, but it does not explicitly state when to use it versus alternatives like 'get_selection' or 'get_node_info'. There is no exclusionary guidance or mention of alternatives, so the usage context is only implied.

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 must disclose behavioral traits. It fails to mention idempotency, reversibility, authorization needs, or side effects beyond the rename operation itself.

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 clear sentence with no wasted words. However, extreme conciseness sacrifices additional context that could improve usability, earning a 4 rather than 5.

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?

Missing output schema and no description of return values. For a mutation tool, users typically need to know if the updated node is returned or just a success indicator. The description is incomplete for safe invocation.

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 100%, so the description adds no new meaning beyond what the schema already provides for the two parameters (nodeId and name). Baseline of 3 is appropriate.

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 explicitly states the action (rename) and the resource (a node in Figma), with a specific verb that clearly distinguishes it from sibling tools like clone_node or delete_node.

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 (e.g., move_node, set_text_content). There is no mention of prerequisites or context, leaving the agent to infer usage from the name alone.

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 full burden of behavioral disclosure. 'Resize a node in Figma' only implies mutation; it does not disclose whether the operation is reversible, how it interacts with auto-layout, constraints, or child nodes, or any side effects. For a mutating tool with zero annotation coverage, this is a significant gap.

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 front-loaded sentence with zero filler: 'Resize a node in Figma' conveys the purpose immediately. It earns its place, though the terseness borders on under-specification rather than deliberate brevity backed by richer content elsewhere.

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?

With no annotations and no output schema, the one-sentence description must carry all context, but it omits what the tool returns, whether changes are undoable, and how resizing affects constraints or auto-layout parents. An agent calling this tool would have to guess at side effects and expected confirmation behavior, which is inadequate even for a simple 3-parameter mutation.

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 100%, so the schema already documents all three parameters with clear descriptions ('New width', 'New height', 'The ID of the node to resize'). The description adds no additional parameter meaning beyond what the schema provides, so the baseline score of 3 applies.

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 a specific verb (resize) and resource (a node in Figma), making the core action unambiguous. It distinguishes from sibling tools because move_node, rename_node, delete_node, and clone_node each carry different verbs, so there is no overlap in what this tool does. It stops short of a 5 because it adds no scope detail (e.g., which node types are resizable) or explicit differentiation language.

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 gives no guidance on when to use this tool versus alternatives such as move_node, set_layout_sizing, or set_layout_mode. There are no conditions, exclusions, or references to siblings, leaving the agent to infer appropriateness entirely from the tool name.

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 full burden. It discloses deduplication and that it returns mainComponent keys, but lacks details on side effects, read-only nature, or performance constraints. Adequate but not comprehensive.

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 two sentences, front-loaded with the action, and contains no extraneous words. Every sentence adds value.

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 optional parameter, no output schema), the description fully covers the purpose, behavior, and use case. No additional information is needed.

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 100% for the single parameter 'nodeId', and the description does not add any semantic meaning beyond what the schema already provides. Baseline of 3 applies.

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 (scan), resource (instances under a node), and outcome (return deduplicated mainComponent keys). It distinguishes from sibling tools like get_instance_info by focusing on discovery of library component keys.

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 a clear use case ('Use to discover published library component keys') but does not explicitly mention when not to use this tool or list alternatives. The context is clear, so it earns a 4.

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 full behavioral burden. It does not disclose whether the scan is recursive or direct-child-only, what happens when no matches are found, whether node types are case-sensitive, or what the response contains. 'Scan' suggests searching, but the exact behavior is left ambiguous.

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 that communicates the core function without filler. The word 'selected' is slightly ambiguous because the actual parameter is nodeId, but the overall structure is efficient.

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?

With no annotations and no output schema, the description leaves out important operational details such as traversal depth, return format, matching behavior, and whether 'selected' refers to the current selection or the provided nodeId. An agent could call it, but may misinterpret scope or results.

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 100%; both nodeId and types already have descriptions in the schema. The tool description adds only the context of scanning child nodes and does not expand on allowed type values, format, or edge cases, so the baseline of 3 is appropriate.

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 a specific action ('Scan for child nodes'), a specific resource ('selected Figma node'), and a specific filter ('specific types'). It is clear enough to distinguish from general node-read tools like get_node_info, though it does not explicitly differentiate itself from scan_text_nodes.

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?

There is no guidance about when to use this tool versus alternatives. It does not mention scan_text_nodes or any other sibling, nor does it state conditions, trade-offs, or exclusions. The usage context is only implicit.

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 present, so the description carries the full burden of behavioral disclosure. It implies a read-only scan but does not explain whether the scan recurses through all descendants, what data is returned, or how results are formatted. 'Scan' alone is too vague for an agent to predict behavior reliably.

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 front-loaded sentence with no filler. It conveys the essential action and object efficiently, though it could include more behavioral detail without becoming bloated.

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 there is no output schema and no annotations, the description should explain what the tool returns or how the scan behaves. It does not mention return values, traversal depth, or any side effects, leaving significant ambiguity for a tool that an agent needs 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?

Schema description coverage is 100%, with nodeId described as 'ID of the node to scan.' The description adds only the phrase 'selected Figma node,' which maps loosely to the parameter but provides no extra semantic value. Baseline 3 is appropriate since the schema already documents the parameter.

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 a specific verb ('scan') and a clear resource ('all text nodes in the selected Figma node'), so an agent can understand the core function. It does not explicitly differentiate from the sibling scan_nodes_by_types, but the focus on text nodes makes the purpose reasonably distinct.

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 about when to use this tool instead of alternatives like scan_nodes_by_types or get_node_info. The context of when this tool is appropriate is left entirely to inference.

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 at all, the description carries the full burden. It discloses that the tool mutates state (create/update) but does not reveal idempotency behavior, whether annotationId is required for updates, what happens if the nodeId does not exist, or whether categoryId is mandatory. The double-action nature also leaves ambiguity about whether an update without annotationId silently creates a duplicate.

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, short sentence with no filler. It front-loads the essential verb and resource. Given the schema carries the parameter details, this level of conciseness is appropriate.

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?

No output schema, no annotations, and a mutation tool with create/update dual semantics. The description does not explain update rules (e.g., what happens when annotationId is omitted for an existing node), merge behavior, or required preconditions like node existence. For a tool with 5 params and two possible operations, this level of context is insufficient.

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 100%, so the parameters are already documented. The description does not add semantics beyond the schema, but the schema descriptions are clear enough. The phrase 'create or update' does imply annotationId is relevant for update, slightly reinforcing the schema, but no extra semantics are added. Baseline 3 is appropriate.

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 'Create or update an annotation' clearly states the verb and resource: it both creates and updates an annotation, which is a specific, common Figma-like operation. It distinguishes itself from siblings like get_annotations (read) and set_multiple_annotations (bulk variant) by explicit create/update semantics, though it does not name those siblings.

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: use when you need to create a new annotation or update an existing one, as indicated by 'Create or update'. There are no explicit exclusions, alternatives, or when-to-use versus set_multiple_annotations guidance, but the context is fairly clear given the sibling list.

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 full burden of behavioral disclosure. It clearly indicates a mutation ('Set'), but it does not mention whether the frame must already be an auto-layout frame, what happens if it is not, whether existing alignment values are overwritten, or whether there are side effects. This is a minimal description for a write 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, front-loaded sentence with no redundant words. It names the action, the object, and the target frame type in an efficient, scannable way.

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 description plus a fully self-documenting schema is enough to identify the core operation and parameters. However, there are no annotations, no output schema, and no guidance about preconditions, failure behavior, or what alignment defaults will be used when optional parameters are omitted. It is minimally viable but leaves meaningful 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?

Schema description coverage is 100%, and the parameter descriptions are already detailed, including enums and the SPACE_BETWEEN behavior note. The tool description itself adds no extra parameter meaning, so the baseline 3 applies.

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 ('Set'), a clear resource ('primary and counter axis alignment'), and specifies the target ('auto-layout frame'). It is immediately distinguishable from siblings like set_item_spacing or set_layout_mode, which address different layout properties.

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 phrase 'for an auto-layout frame' implies the tool is meant for use on frames that have auto-layout enabled, but it does not explicitly state when to choose this tool over related siblings such as set_layout_mode or set_item_spacing. No alternatives or exclusions are mentioned, so usage is inferred rather than explicitly guided.

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 full burden of disclosing behavioral expectations. 'Set the corner radius' conveys a basic mutation, but it does not mention that the change is persistent, whether unsupported node types will error, how the optional corners parameter interacts with the radius, or whether existing radius values are overwritten. For a mutation tool with no annotation coverage, this is a significant gap.

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, front-loaded sentence with no filler or redundancy. Every word contributes to identifying the tool's action and target. The under-specification of behavioral details is a completeness issue, not a conciseness issue.

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?

For a simple three-parameter tool with complete schema coverage, the core invocation details are present. However, with no annotations and no output schema, the description leaves important context unstated: how to obtain a valid nodeId, whether all nodes support corner radius, and what happens when corners is omitted. This is adequate but not robust.

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 100%, so the schema fully documents nodeId, radius, and the optional corners array. The description adds no parameter-specific meaning beyond echoing the general concept of corner radius. This is the expected baseline when the schema already handles parameter documentation.

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 a specific verb ('Set') and resource ('corner radius of a node in Figma'). This meaningfully distinguishes it from sibling tools like set_fill_color, resize_node, or set_padding. Even without a title, the purpose is immediately 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 intended use case is implied by the tool name and description: use it when you need to change a node's corner radius. However, there is no explicit guidance about when not to use it, what node types support corner radius, or how it relates to alternative tools such as resize_node or set_padding. It meets the threshold for implied usage but provides no explicit routing or exclusions.

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 full burden of behavioral disclosure. It states the operation but does not mention that this is a mutation, whether it affects the underlying design, any required permissions, side effects, or failure conditions. The word 'set' implies state change but provides no transparency beyond that.

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, front-loaded sentence with no filler or redundant details. Every word earns its place, and the key constraint ('copied') is included without bloating the 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?

For a one-parameter setter with no output schema and no annotations, this is minimally adequate: the agent knows what to do and which parameter to provide. However, it lacks behavioral context such as side effects, when the node is considered 'copied', and what being 'default' entails, leaving meaningful gaps for correct invocation and expectation-setting.

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 already provides a clear description for connectorId, and coverage is 100%, so the baseline is 3. The tool description adds the important constraint that the connectorId must refer to a copied connector node, which goes beyond the schema's generic 'connector node' description.

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 ('set'), the resource ('connector node'), and the desired outcome ('as the default connector'). It is specific enough to distinguish this tool from most siblings, though it does not explicitly contrast it with any alternative or define what 'default connector' means in this context.

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 phrase 'copied connector node' implies that the tool should be used after copying a connector node, giving some usage context. However, there is no explicit guidance about when to prefer this tool over alternatives, nor any exclusions or workflow prerequisites.

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 provided, so description must disclose behavioral traits. It does not mention whether existing effects are replaced, merged, or if there are limits on number or types of 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?

Single sentence, no redundant or filler content. Efficiently states the core purpose.

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?

As a mutation tool with no output schema, the description should cover return behavior (e.g., returns nothing or updated node). Missing details on idempotency, error conditions, or scope covering all node types.

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 100%, so all parameters are documented. The description adds 'shadow, blur' context, but does not explain behavioral nuances like effect ordering or visibility defaults.

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 ('Set visual effects') and the scope ('on a node'), with examples ('shadow, blur') that distinguish it from sibling tools like set_fill_color or set_stroke_color.

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 (e.g., set_fill_color for fills), no prerequisites, and no indication of when effects are replaced or added.

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?

Annotations are absent, so the description carries the full behavioral burden. It adds the supported node types, but does not disclose whether existing fills are replaced, what happens for unsupported node types, or how the optional alpha parameter behaves. 'Set' implies mutation, but deeper behavioral context is missing.

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 action and target, avoiding unnecessary detail. However, the grammar is slightly awkward in the trailing clause, which prevents a higher score.

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?

For a simple setter with fully documented parameters and no output schema, the description is mostly adequate. It is missing edge-case behavior details, especially around the optional alpha parameter and unsupported node types, but remains functional for basic invocation.

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 100%, with clear parameter descriptions, ranges, and required flags. The tool description adds no additional parameter-level meaning, so the baseline 3 is appropriate.

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 a concrete action ('Set') and target ('fill color of a node'), and adds supported node types (TextNode or FrameNode). This is clear enough to distinguish it from stroke-related or image-fill siblings, though it does not explicitly name alternatives.

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 when-to-use or when-not-to-use guidance is provided. It does not mention alternatives such as set_stroke_color or set_image_fill, leaving an agent to infer appropriate usage from the tool name and schema alone.

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 carries the full burden of behavioral disclosure. It explicitly mentions both side effects—selecting the node and scrolling the viewport—which is strong transparency for this type of tool. It does not discuss error cases or whether document state changes, but the main observable behavior is disclosed.

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 front-loaded sentence with no filler. It states the operation, the target, and the mechanism in an efficient and scannable way.

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?

For a simple, one-parameter tool with no output schema, the description provides sufficient context: what action is performed and what visible effects occur. It does not mention return behavior or failure handling, but for a focus/selection action this is a minor gap rather than a critical omission.

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 100%, and the nodeId parameter is already described as 'The ID of the node to focus on.' The tool description does not add additional parameter meaning, format details, or constraints, so it stays at the baseline for fully schema-documented parameters.

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 a specific action—set focus on a node—and adds concrete behavioral detail: selecting the node and scrolling the viewport to it. This distinguishes it from related selection tools, though it does not explicitly reference any sibling tool by name.

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?

There is no guidance about when to use this tool instead of alternatives such as set_selections or move_node. The description implies a use case, but it does not state prerequisites, exclusions, or conditions that would route an agent to a different tool.

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 provided. Description does not disclose whether the operation is destructive, requires permissions, or what side effects occur (e.g., overwriting existing font properties). Minimal behavioral context.

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?

Single, concise sentence with no extraneous information. All words contribute meaning.

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?

For a mutation tool with 4 parameters and no output schema or annotations, the description covers the basic action but lacks details on return values or behavioral effects. Adequate but not comprehensive.

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 100% with all parameters described. Description echoes schema terms ('family, style, size') but adds no new meaning beyond that. Baseline 3 is appropriate.

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?

Description clearly states the action ('Set') and the resource ('font family, style, and size on a text node'). It effectively distinguishes from siblings like set_text_content (content) and create_text (creation).

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 (e.g., set_text_content for text changes). Lacks any 'when to use' or 'when not to use' advice.

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?

Without annotations, the description should disclose effects. It only says 'set a gradient fill' but doesn't confirm it replaces existing fills, requires a node with a fill property, or if gradientType changes are reversible.

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?

Single sentence is concise but lacks structure. Could be expanded with key details without being verbose.

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?

Despite full schema coverage, the description fails to contextualize parameters like stops (array of objects) or angle (only for linear). No output schema, so more context needed.

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 100%, baseline 3. The description adds no additional meaning beyond the schema, e.g., explaining that stops positions must be sorted or that angle is only for linear.

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 'Set' and the resource 'gradient fill on a node'. It distinguishes from sibling tools like set_fill_color and set_image_fill by specifying gradient.

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 instead of alternatives like set_fill_color, nor prerequisites or context (e.g., node must have a fill area).

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 the full burden. It indicates a mutation but does not disclose side effects, permission needs, error behaviors, or whether the image fill replaces or appends to existing fills.

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, focused sentence with no extraneous words, making it efficient and easy to parse.

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?

For a tool with three parameters and no output schema, the description is minimal. It covers the basic action but lacks context on expected behavior, error handling, and return values, leaving gaps an agent might need.

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 100% (all three parameters have descriptions in the schema). The description adds no further parameter details beyond the schema, meeting the baseline expectation.

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 (Set) and resource (image fill on a node) with a distinguishing aspect 'from a URL' that differentiates it from sibling tools like set_fill_color or set_gradient_fill.

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 when an image fill from a URL is desired, but it does not provide explicit guidance on when to use or avoid this tool versus alternatives, nor any prerequisites or exclusions.

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 full burden of behavioral disclosure. It explicitly reveals the main mutating effect: target instances will be swapped to the source component and all copied override properties will be applied. It does not discuss reversibility, errors, or permissions, but the core behavioral transformation is clearly stated, which is strong for a tool with no annotation support.

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 two concise sentences with no filler. The main action is front-loaded in the first sentence, and the second sentence adds the essential behavioral detail. Every word contributes to the agent's understanding.

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?

For a tool with two required parameters, no annotations, and no output schema, the description covers the action, the target selection context, and the resulting transformation. It could mention prerequisites more explicitly or describe failure behavior, but the essential information needed to invoke the tool correctly is present.

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 100%, so the schema already documents both parameters. The tool description adds minimal parameter-level meaning beyond restating that target instances are involved; it does not clarify the relationship between sourceInstanceId and targetNodeIds beyond what the schema already provides. Thus 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.

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

The description opens with a specific verb and resource ('Apply previously copied overrides to selected component instances') and then states the concrete outcome: target instances are swapped to the source component and all copied overrides are applied. This clearly distinguishes it from the sibling get_instance_overrides, which reads rather than applies.

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 phrase 'previously copied overrides' and 'selected component instances' conveys the intended workflow context, making it clear the tool is used after copying overrides and on a current selection. It does not explicitly state when not to use it or name alternatives like get_instance_overrides, but the context is sufficient for an agent to infer the correct situation.

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 exist, so the description carries the full burden. It describes the action as setting properties, but does not mention side effects, permissions, or error conditions. It is not misleading but lacks depth.

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 sentence with an example, front-loading the key information. No wasted words; every part earns its place.

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?

With two parameters and no output schema, the description adequately covers purpose and usage. It lacks details about return values, but for a mutation tool this is acceptable. Given the complexity, it is sufficiently 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?

Schema coverage is 100% with descriptions for both parameters. The description adds value by providing an example property object, which clarifies the expected format beyond the schema's generic description.

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 explicitly states 'Set component properties on an instance' with a concrete example (switch Platform from Desktop to Mobile). This clearly differentiates from sibling tools like set_instance_overrides, which likely set different types of properties.

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 an example usage, but does not explicitly state when to use this tool versus alternatives like set_instance_overrides. However, the context of 'component properties' vs 'overrides' is implied.

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 full behavioral disclosure burden. It only states the basic mutation ('Set distance') and does not describe failure modes for non-auto-layout frames, side effects, or behavioral caveats like itemSpacing being ignored under certain alignment settings.

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 front-loaded sentence with no filler. Every word contributes to identifying the operation's target and scope.

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 schema covers parameter semantics well, and the description names the target context, but with no annotations and no output schema, an agent still lacks guidance on alternatives and behavior beyond the basic mutation. It is adequate but not fully 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?

Schema description coverage is 100%, and each parameter already has meaningful descriptions, including caveats for itemSpacing and counterAxisSpacing. The tool description adds no parameter-level meaning beyond the schema, so the baseline score of 3 applies.

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 ('Set') and identifies the exact resource ('distance between children in an auto-layout frame'). This clearly differentiates it from related siblings like set_padding and set_axis_align, even though no sibling is named explicitly.

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 gives a clear applicable context: it only applies to auto-layout frames, which tells an agent when the tool is relevant. However, it does not explicitly mention alternatives or exclude cases such as fixed-layout frames.

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 side effects and constraints on its own. It only says 'set', with no mention that this mutates design state, that layoutWrap may only apply when layoutMode is not NONE, or any other behavioral consequences. For a mutation tool, this is a significant transparency gap.

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 sentence with no filler or repetition. It front-loads the action and resource, making it easy to scan and understand quickly.

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 description plus the fully covered schema give an agent enough basics to invoke the tool, but there are no behavioral notes, no usage context, and no output expectations. Since it is a simple three-parameter mutation, this is minimally viable but still leaves selection ambiguity among similar sibling tools.

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 100%, so each parameter is already documented. The description adds no meaning beyond restating that layout mode and wrap behavior are affected. Baseline 3 is appropriate because the schema carries the burden, and the description neither adds nor conflicts with parameter details.

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 names a specific verb ('Set'), a resource ('a frame in Figma'), and the affected properties ('layout mode and wrap behavior'). It is clear enough to identify the tool's core function, but it does not distinguish itself from sibling layout-related tools like set_axis_align or set_layout_sizing.

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?

There is no guidance on when to use this tool versus alternatives, no prerequisites such as the frame needing to be an auto-layout frame, and no exclusions. The only usage signal is implied by the verb and resource, which is not enough for an agent to reliably choose between this and similar layout tools.

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 carries the full burden of behavioral disclosure. It states the action but does not explain side effects, requirements (e.g., node must already be an auto-layout frame), or consequences of changing sizing modes. This leaves the agent without important behavioral context for a mutation 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, clear, front-loaded sentence with no redundant words. It efficiently communicates the core purpose without unnecessary elaboration.

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?

For a simple setter with a fully documented schema, the description plus schema is mostly adequate. However, the lack of usage guidance and behavioral caveats means the agent may not know when to prefer this tool or what assumptions to make about the target node, leaving minor but notable 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?

Schema description coverage is 100%, so the schema already documents each parameter and its enum meanings. The description adds the high-level context of setting sizing modes but does not add meaning beyond the schema descriptions for the individual parameters.

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 ('Set') and resource ('horizontal and vertical sizing modes for an auto-layout frame in Figma'), making the tool's function immediately clear. It also distinguishes itself from siblings like set_layout_mode, which focuses on layout mode rather than sizing modes.

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 the tool is for auto-layout frames, giving some context for when to use it. However, it does not explicitly state when to use this tool over alternatives such as set_layout_mode or resize_node, nor does it mention any exclusions or prerequisites.

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 full burden of behavioral disclosure. 'Set' implies mutation, but the description does not state whether existing annotations are replaced, whether updates require annotationId, how partial failures are handled, or any other 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 a single short sentence with no filler words, making it easy to parse. It is concise rather than bloated, though it sacrifices useful detail for brevity.

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 involves a nested annotations array with optional categorization and update IDs, yet the description only says to set multiple annotations. There is no guidance on how updating existing annotations works, what 'in a node' means relative to the nested nodeId, or what happens after the operation. With no output schema and no annotations, this is insufficient for reliable invocation.

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 provides thorough descriptions for the top-level parameters and most nested fields, so the description adds little beyond schema. A baseline of 3 is appropriate since the schema does the heavy lifting; the description does not clarify ambiguous points like how categoryId/annotationId relate to creating versus updating.

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 a clear verb and resource: 'Set multiple annotations' in a node, which conveys a batch mutation operation. It is implicitly distinct from the singular sibling tool set_annotation, though it does not explicitly name the alternative.

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 explicit guidance is provided about when to use this tool versus set_annotation, get_annotations, or other annotation-related tools. The word 'multiple' implies batch usage, but there is no stated condition, exclusion, or alternative recommendation.

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 full burden of behavioral disclosure. It only reveals that the operation sets multiple text contents 'parallelly', but does not state whether existing text is replaced, whether the node must contain text nodes, or whether the operation is atomic.

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 sentence with no filler and the action verb is front-loaded. However, 'parallelly' is an awkward modifier and 'text contents' is imprecise, so it is concise but not maximally polished.

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?

For a mutation tool with no annotations and no output schema, the description is thin. It omits how this tool relates to set_text_content, what 'parallelly' means in terms of execution, and any side effects or prerequisites, though the schema covers the parameter mechanics.

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 100%, so the baseline is 3. The description adds little beyond the schema: 'parallelly' and 'in a node' hint at the relationship between the parent node and the array, but the schema already documents both parameters and their roles.

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 ('Set') and resource ('multiple text contents') and scopes the operation to 'a node'. The word 'multiple' differentiates it from the sibling set_text_content, though 'parallelly' is vague and 'text contents' is slightly ambiguous.

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 explicit when-to-use guidance or alternatives are stated. The term 'multiple' implies this is the batch counterpart to set_text_content, but the description never clarifies when to choose this over the singular tool or what types of nodes are valid.

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?

There are no annotations, so the description carries the full behavioral burden. It only states that padding values are set, but does not disclose whether unspecified padding values are preserved or reset, whether the frame must already have auto-layout enabled, or what happens if the node is not a valid auto-layout frame.

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 that is front-loaded with the action and resource. It has no wasted words, though it is somewhat minimal and leaves out behavioral details.

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 there are no annotations or output schema, the description should provide more behavioral context for this mutating tool. It does not explain partial-update behavior, constraints on the target frame, or error conditions, so an agent lacks important information for correct invocation.

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 covers all parameters with descriptions, giving a baseline of 3. The description adds no extra meaning beyond the schema, but it does not need to since the schema already defines nodeId and each padding side clearly.

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 ('Set'), a clear resource ('padding values'), and a precise scope ('auto-layout frame in Figma'). It is easy to distinguish from sibling tools like set_item_spacing or set_layout_mode because padding is uniquely identified.

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 the tool is for auto-layout frames, giving some context, but it does not explicitly say when to choose this tool over alternatives or when not to use it. There is no mention of related tools for spacing or layout adjustments.

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 provided, so description bears full burden. It does not disclose whether reactions are replaced or appended, if the operation is irreversible, or any side effects. 'Set' is vague about overwriting semantics.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
