Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.1.0
Disambiguation5/5
Each tool targets a specific Linode resource and action (get vs list), with clear naming. Even similar tools like 'list_instances' and 'get_instance' are distinct by scope (all vs single). No overlapping purposes.
Naming Consistency5/5
All tools follow the consistent pattern 'linode_<verb>_<noun>' in snake_case. Verbs are limited to 'get', 'list', 'find', and 'estimate', making it predictable and easy to navigate.
Tool Count4/5
37 tools is high but appropriate for covering the broad Linode API surface (compute, storage, network, databases, DNS, etc.). A few utilities like 'list_database_types' and 'list_database_engines' could be merged, but overall the count is justified.
Completeness4/5
For a read-only toolset, coverage is comprehensive across major Linode resources (instances, volumes, firewalls, LKE, DNS, Object Storage). Minor gaps exist (e.g., SSH keys, StackScripts), but core infrastructure is well-covered.
Average 4/5 across 37 of 37 tools scored. Lowest: 3/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=true, and the description's 'List' verb is consistent. However, the description adds no further behavioral context (e.g., authentication, scope, or side effects).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, clear sentence that is front-loaded and efficient. However, the brevity comes at the cost of omitting parameter information, which could be added without significant length.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has one optional parameter, the description should explain its usage. The output schema exists, but the description's omission of the parameter logic leaves the definition incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has an undocumented 'detail' parameter (0% coverage) and the description fails to explain its meaning or effect. The description adds no value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists NodeBalancers and specifies the returned fields (region, hostname, IPs, transfer usage), making it distinct from sibling list tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No usage guidelines are provided. The description does not indicate when to use this tool vs. other list tools, or 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the description adds minimal behavioral insight beyond stating the output fields. No mention of pagination, authorization, or rate limits. The description doesn't contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence of 9 words, front-loaded with verb and resource. No wasted words; perfectly concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite having an output schema and annotations, the description omits the only input parameter, which is crucial for controlling output detail. This gap makes it incomplete for effective tool use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% and the description does not mention the optional 'detail' parameter at all. While it lists output fields, it fails to explain how the parameter controls detail level, leaving the agent to infer without guidance.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description explicitly states the verb (List), resource (VLANs), and output fields (region, CIDR, attached instances). It clearly distinguishes from siblings like 'linode_list_vpcs' which lists VPCs, not VLANs.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool vs alternatives. The purpose is clear from the name, but the description does not provide proactive context or exclusions. It's adequate but lacks depth.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true. The description adds that it lists events but does not specify behavior related to the 'detail' parameter (e.g., what full vs concise returns) or any other traits like pagination or rate limits. No contradictions with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence with no extraneous words. Every piece of information (verb, resource, content summary) is essential and immediately useful.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given a simple tool with one optional parameter and an output schema, the description provides the basic purpose but misses the 'detail' parameter and any mention of pagination or time ranges. It is minimally complete but has clear gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must explain parameters. However, it does not mention the 'detail' parameter or its enum values ('concise', 'full'), leaving the agent uninformed about how to control output verbosity.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('List') and resource ('recent account events (the audit log)'), clearly distinguishing it from siblings like linode_list_instances or linode_list_firewalls. The parenthetical 'audit log' adds clarity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives (e.g., other list tools or generic linode_api_get). The description does not mention prerequisites, exclusions, or context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=true, which is consistent. The description adds value by specifying that payment-method detail is redacted, a behavioral trait beyond the annotation. It also lists the fields returned.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence with no unnecessary words. It front-loads the main purpose and includes key details efficiently.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With an output schema present, the description does not need to detail return values. It covers the main fields and the redaction trait. However, it omits pagination or filtering details that might be expected for a list tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The optional parameter 'detail' is not described in the description. Schema description coverage is 0%, so the description should compensate but fails to explain its purpose or effect.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists invoices with specific fields (date, subtotal, tax, total) and mentions redaction of payment-method detail. It distinguishes this from other list tools by its focus on invoices, though no explicit differentiation from sibling tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives like linode_estimate_cost or linode_get_account. It does not specify prerequisites or context for its use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the read-only nature is known. The description adds value by specifying returned fields (region, type, status, IPs, image, specs) and the scope ('in the account'), going beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with the core action and followed by a usage directive. No redundant information. Efficient and clear.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the main purpose and returned fields, but the missing parameter explanation and lack of mention of pagination or ordering make it incomplete for a list tool with one optional parameter. Adequate but not thorough.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description does not explain the 'detail' parameter despite 0% schema description coverage. The parameter's enum values ('concise', 'full') are undocumented, leaving the agent to guess. This is a significant gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it lists Linode compute instances for the account and enumerates returned fields (region, type, status, IPs, image, specs). This distinguishes it from sibling tools like linode_get_instance (single instance) and other list tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a use case ('Use to inventory what is running') but does not explicitly state when not to use it or mention alternatives like linode_get_instance for a single instance. Usage context is implied but not fully guided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds behavioral context beyond the readOnlyHint annotation by stating that the kubeconfig is never returned, which is a critical safety note. It also clarifies the output fields, giving the agent a better understanding of the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise, consisting of two short sentences that front-load the core purpose and add one key behavioral note. Every sentence adds value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the main output but omits any mention of the 'detail' parameter. Given the simple tool with one optional parameter, the description is adequate for a basic understanding but not fully complete regarding usage of the parameter.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The only parameter 'detail' has an enum ['concise', 'full'] but the description does not explain its purpose or effect. With 0% schema description coverage, the description fails to compensate, leaving the agent without guidance on how to use the parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists LKE clusters in the account, specifying the resource (LKE clusters) and the action (list). It also details what attributes are returned (region, Kubernetes version, tier, control plane settings) and distinguishes itself from sibling tools like linode_get_lke_cluster by the operation type.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not provide explicit guidance on when to use this tool versus alternatives. It does not mention criteria for choosing between list and get operations, nor does it state any prerequisites or conditions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
ReadOnlyHint annotation already signals safety; description adds that access keys are never returned, providing extra behavioral context. However, no details on rate limits, authentication, or idempotency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, front-loaded with action and resource, followed by output fields. No unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given output schema exists and annotation covers safety, description enumerates key return fields (hostname, S3 endpoint, etc.) and notes access key omission. Slightly lacking in prerequisites or error scenarios.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%; description only hints that 'region' and 'name' (bucket) are used, but does not explain format, constraints, or provide example values, insufficiently compensating for missing schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states 'Get details for a single Object Storage bucket by region and name' and enumerates specific fields returned (hostname, S3 endpoint, etc.), distinguishing it from siblings like linode_list_object_storage_buckets.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies it is for retrieving details of a single bucket, contrasting with list tools, but provides no explicit when-to-use or when-not-to-use guidance or alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already include readOnlyHint=true, so the description adds no extra behavioral context. The description simply restates the action without disclosing side effects, return format, or other behavioral traits beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, well-formed sentence with no unnecessary words. Every word serves to explain the tool's purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has no parameters and an output schema exists, the description is complete: it states what the tool returns and its context. No additional information seems necessary for an agent to invoke it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, so the description does not need to add parameter details. According to guidelines, 0 parameters merits a baseline of 4. The description does not contradict the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'List', the resource 'database engines and versions', and the scope 'available for new Managed Database clusters'. This sufficiently distinguishes it from siblings like linode_list_database_types, which lists database types instead.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. Given the presence of similar sibling tools (e.g., linode_list_database_types), explicit differentiation or usage context would help an agent 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.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the description's addition that the 'root password is never returned' provides useful behavioral context. However, it does not elaborate on other behaviors like pagination or error conditions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences with critical information front-loaded. No superfluous words; each sentence adds value. The structure is ideal for quick comprehension.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the tool's purpose, scope, and a key behavioral note (password exclusion). The output schema likely documents return structure, but the missing parameter explanation slightly reduces completeness. Overall, adequate for a simple list operation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single parameter 'detail' is not mentioned in the description. With 0% schema description coverage, the description should explain the parameter's effect (e.g., controlling field verbosity). This omission leaves the agent unsure of how to use the parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states the verb 'List', the resource 'Managed Database clusters', the scope 'in the account (all engines)', and lists specific fields returned. This clearly distinguishes it from sibling list tools like linode_list_database_engines and linode_list_database_types.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for listing all database clusters but does not provide explicit guidance on when to use this tool versus alternatives. There is no mention of prerequisites, filtering, 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.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, indicating a safe read operation. The description adds value by detailing the returned data (type, region, reverse DNS, instance). No additional behavioral traits are disclosed beyond annotations, but the description is sufficient given the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence that is front-loaded with the main purpose and includes key details. No unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has an output schema, so return value details are covered. The description lists the main fields. However, it misses documentation of the optional 'detail' parameter, which could affect completeness for filtering the output.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, meaning the 'detail' parameter has no description in the schema. The tool description does not mention the parameter or explain its meaning or usage, leaving the agent without guidance on how to use the optional parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists IP addresses on the account and specifies the attributes included (type, region, reverse DNS, instance). It is a specific verb-resource combination and distinguishes itself from sibling tools, as no other tool lists IPs.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage when IP address details are needed but provides no explicit guidance on when to use this tool versus alternatives, nor does it mention when not to use it. Among siblings, there are many list tools, but no direct alternative for IPs.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide readOnlyHint=true, and the description adds valuable context: access keys are never returned and lists specific output fields. This exceeds the annotation's minimal disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two brief sentences front-load the key information. Every word adds value—no fluff, no repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Adequate for a list tool but missing explanation of the detail parameter. Output schema may cover return values, but parameter documentation gap reduces completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so description must compensate. It explains the region parameter ('optionally scoped to one region') but does not mention the detail parameter (concise/full). Thus only partial compensation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states 'List Object Storage buckets' with optional region scoping, specifying returned fields. Distinguishes from sibling tools like linode_get_object_storage_bucket (singular) and linode_list_object_storage_endpoints (different resource).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives. No mention of prerequisites or exclusions. The optional region parameter is noted but not contextualized against other listing tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description is consistent with the readOnlyHint annotation, adding that it returns specific attributes. However, no additional behavioral traits (e.g., pagination, sorting, rate limits) are disclosed beyond what annotations already indicate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, well-structured sentence that immediately states the action and output. No wasted words; it is appropriately concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity of the tool (list with one optional parameter and an output schema), the description adequately covers the primary functionality. Some details about pagination or the detail parameter could improve completeness, but it meets basic needs.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description does not explain the 'detail' parameter or its effect on output, despite the schema having 0% coverage. The parameter is optional, but its meaning (concise vs full) is left entirely to the schema, which is insufficient.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'List the block storage volumes in the account' with specific output fields (size, region, status, attached instance), making the purpose unambiguous and distinguishing it from sibling tools that list other resources.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for listing volumes, but does not explicitly state when to use this tool vs alternatives (e.g., filtering, singular get), nor does it provide exclusions or context. However, the sibling tool list clarifies it's a general list operation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=true. The description adds value by specifying that the listing includes region and description, and importantly states that subnets are not included, which is not obvious from annotations or schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, each earning its place: first states purpose and included fields, second clarifies what is not included. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given an output schema exists, the description adequately covers the tool's purpose and boundary. However, the missing parameter guidance prevents full completeness, especially for a tool with only one parameter.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage for the 'detail' parameter, and the description does not mention the parameter at all. The agent receives no guidance on what 'detail' does or when to use 'concise' vs 'full'.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists VPCs with their region and description, and explicitly distinguishes from get_vpc by noting that subnets are returned by get_vpc, not here.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies that for subnets one should use get_vpc, but does not explicitly state when to use this tool versus other listing tools or provide exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so no contradiction. Description adds specific fields returned, but does not disclose additional behaviors like error handling or access requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences front-loading purpose and key returned data, with zero wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With an output schema present, description needn't detail return values. It covers the core retrieval scenario, though could mention required permissions or that domain must exist.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has one integer parameter domain_id with 0% description coverage. Description merely says 'by id', adding minimal value. No guidance on valid values or how to obtain a domain ID.

It does not mention the region parameter or provide exhaustive detail, but it is sufficient for an AI agent to understand the tool's capability.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description bears the burden. It partially compensates by listing the major components (instances, volumes, NodeBalancers, LKE tier, Object Storage) but does not explain all parameters like region, extra_egress_gb, or default values. The description adds meaning beyond the schema but is incomplete for all nested parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool estimates hourly and monthly cost of a composite stack, listing specific components like instances, volumes, NodeBalancers, LKE tier, and Object Storage. It distinguishes itself from siblings like linode_get_pricing by focusing on estimation of combined resources.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states the tool's purpose: 'Summarize the account limits that apply.' It also details the specific components it composes (API rate limits, Object Storage quotas, network transfer pool), clearly distinguishing it from sibling tools like linode_get_account or linode_list_* which retrieve other types of data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implicitly suggests usage when account limits are needed, noting that Linode does not expose a single endpoint. However, it lacks explicit guidance on when to use this tool versus alternatives, such as linode_list_object_storage_quotas or linode_get_account_transfer, and provides no '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.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (get a single entity) and the presence of an output schema, the description covers all essential aspects: what is retrieved, how to identify it (engine and id), what fields are returned, a critical constraint on engine, and a notable omission (root password). The agent has enough context to invoke the tool correctly without further clarification.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage for its two parameters. The description compensates partially by specifying that 'engine' must be 'mysql' or 'postgresql' and suggests a source for it. However, it provides no details about 'database_id', leaving the agent to infer its name and type. A score of 3 reflects partial, but incomplete, parameter guidance.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Get', the resource 'one Managed Database', and the identifiers 'engine and id'. It lists the returned fields (version, region, status, host, port, maintenance window), making the tool's purpose specific and unambiguous. The name and description differentiate it from sibling list tools like linode_list_databases.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?

Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description adds minimal meaning: it states the parameter is an ID. However, since there is only one parameter, this is adequate but not rich. Baseline for low coverage is 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Get' and the resource 'one Cloud Firewall by id'. It distinguishes from sibling tools like linode_list_firewalls (which lists all) by specifying it returns a single firewall including its rules and attached resources.

Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage when you have a specific firewall ID and need detailed information. It does not explicitly exclude alternatives, but the context among sibling tools makes it clear that this is for single retrieval.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=true, so the safety profile is clear. The description adds behavioral context by specifying that the tool returns subnets and instances, which is beyond what the name implies. No contradictions with annotations.

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action 'List the Managed Database plan types' and enumerates the attributes returned (vcpus, memory, disk, supported engines, price). This distinguishes it from sibling tools like linode_list_databases (lists database instances) and linode_list_database_engines (lists engines).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for retrieving database plan type details, but it does not explicitly state when to use this tool over alternatives or provide any exclusions. The context from sibling names provides some guidance, but the description itself lacks direct usage heuristics.

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'List' and resource 'Linode instance plan types', explicitly enumerating the attributes returned (vcpus, memory, disk, etc.). This distinguishes it from sibling tools like linode_list_instances or linode_get_pricing which serve different purposes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly states 'Use to compare plans or find a type id for cost estimates', providing clear guidance on when to use the tool. It lacks explicit when-not-to-use or alternative suggestions, but the sibling list includes other related tools, making the context reasonably clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotation already declares readOnlyHint=true, so the description doesn't need to reiterate safety. It adds value by specifying the scope ('available to the account') and the returned attributes, which are beyond the annotation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that immediately states the action and details. No filler words or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given zero parameters, a complete input schema, and the existence of an output schema, the description fully conveys what the tool does. It provides enough context for an AI agent to understand its purpose without ambiguity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are zero parameters, and schema coverage is trivially 100%. Per the calibration rule, baseline is 4. The description could optionally mention that no parameters are needed, but it's not necessary.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('List') and the resource ('Object Storage endpoints'), and specifies the returned fields (region, endpoint type, S3 hostname). It distinguishes itself from sibling tools like linode_list_object_storage_buckets by focusing specifically on endpoints.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool vs alternatives is provided. However, the name and description make the purpose obvious, and no when-not scenarios are needed given zero parameters. The implied context is sufficient for a simple list operation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so description does not need to restate. It adds transparency about scope (Object Storage specific), which is useful context beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences that front-load the action and provide essential context without extraneous words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a parameterless tool with an output schema, the description fully covers what the tool does and its scope. No additional context is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameters exist and schema coverage is 100%. Description does not need to add parameter info; baseline of 3 is appropriate as it does not mislead.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states 'List Object Storage quotas for the account' with specific verb and resource. It distinguishes from siblings by noting it is the only quota API and scoped to Object Storage, not the whole account.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Description provides context that this is the only quota API and scoped to Object Storage, helping the agent understand when to use it. However, it does not explicitly contrast with sibling tools like linode_get_account_limits or state 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.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the readOnlyHint annotation, the description adds a critical behavioral trait: 'The kubeconfig is never read or returned, even if asked.' This prevents misuse and sets accurate expectations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no fluff. The main action is front-loaded, and the caveat about kubeconfig is efficiently communicated in the second sentence.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the output schema exists, the description covers all necessary behavioral aspects: what is included (node pools, endpoints, ACL) and what is excluded (kubeconfig). It is complete for a simple one-parameter get tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage, and the description only mentions 'by id' without explaining the cluster_id parameter. However, the parameter name is self-explanatory; the description adds minimal value over the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Get one LKE cluster by id' with specific components (node pools, API endpoints, control plane ACL). It distinguishes from sibling tools like linode_list_lke_clusters by specifying it retrieves a single cluster.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage when you have a cluster ID and need details, but does not explicitly state when to avoid it (e.g., if kubeconfig is needed). The context is clear but lacks explicit alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=true, so no safety concern. The description adds value by detailing the return structure (price, regions, separate listing for marketing SKUs) and optional region filtering, which goes beyond bare read-only indication.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise at two sentences, front-loading the main purpose. Every sentence adds essential information with no redundancy or filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple input (one optional parameter) and presence of an output schema, the description fully covers the tool's behavior. It mentions output content (price, regions, marketing SKUs) and optional scoping.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description must compensate. It clarifies that 'region' is optional and scopes results, which adds meaning beyond the raw schema. However, it does not specify format or allowed values.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool finds GPU and accelerated compute plans and their availability, specifying the classes (NVIDIA RTX, NETINT VPU) and what is returned (price, regions). It distinguishes from other tools by focusing on GPU and accelerated plans.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explains when to use the tool (to find GPU/accelerated plans and availability) and optional region scoping. It does not explicitly mention alternatives or when not to use it, but the purpose is clear enough for an agent to select appropriately among siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the description does not need to state safety. It adds value by listing the detailed fields returned, which helps the agent understand the output without invoking the tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but the description clarifies the parameter's role ('by id'). While it could mention how to obtain the ID (e.g., from list), the parameter name and context are self-explanatory.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool gets one Linode instance by ID and lists the returned fields (region, type, status, IPs, image, specs). This distinguishes it from the sibling tool linode_list_instances, which returns a list.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use when you have a specific instance ID, as opposed to listing all instances. It does not explicitly exclude alternative tools, but the sibling context makes the distinction clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, and the description aligns by indicating it returns availability data without mutation. It adds value by explaining the scoping behavior (with/without region) beyond the annotation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise at three sentences, front-loading the main purpose. Every sentence contributes essential information without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has one optional parameter and an output schema exists (as per context), the description fully covers the two usage modes and the purpose. It is complete for an agent to select and invoke correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single parameter 'region' lacks schema description (0% coverage), but the description compensates by explaining its effect: without it returns account-wide, with it scopes to one region, including an example value 'us-east'. This provides necessary semantic meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool shows which plans are in stock, using a specific verb 'Show' and resource 'plans'. It distinguishes from siblings by focusing on region availability rather than listing instances or other resources.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explains two scenarios: without argument (account-wide) and with a region id (scoped). It states the purpose 'to find where a plan is available', providing clear context. However, it does not explicitly list when not to use it or suggest alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds context beyond the readOnlyHint annotation by specifying the fields returned (capabilities, country, site type, status), which is sufficient for a simple read-only operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences, front-loaded with the verb and resource, and no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of parameters, read-only nature, and presence of an output schema, the description provides all necessary context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses that only GET is allowed (matching readOnlyHint annotation), refuses secret-returning endpoints, and scrubs response of secrets. Adds significant behavioral context beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Three short sentences, each adding critical information: purpose, allowed method, restrictions. No filler. Front-loaded with key details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers input, restrictions, and security. No output schema, but response scrubbing is noted. Sufficient for an agent to use as a general-purpose escape hatch, though return format is not specified.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but description explains 'path' as relative v4 path and 'params' as optional query params, with an example. Adds meaning beyond the bare schema, though missing explicit descriptions of each parameter individually.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
States it is a read-only escape hatch for GET requests against Linode API v4 paths not covered by curated tools, with examples like '/images' or '/databases/engines'. Clearly distinguishes from sibling tools.
