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 distinct operation within a well-defined module (associations, CRM objects, properties, workflows, enrollments, quotes, automation callbacks). Overlaps are only between individual and batch variants, which are clearly differentiated by name and description.
Naming Consistency5/5
All tools follow the consistent pattern 'hubspot_<module>_<action>', with actions using clear verbs (create, get, list, update, delete, archive, etc.). Batch variants and legacy versions are indicated by predictable prefixes ('batch_', 'v3_').
Tool Count2/5
With 37 tools, the server exceeds the recommended range of 3-15 for a well-scoped set. While the domain (HubSpot CRM + Automation) is broad and each tool has a clear purpose, the sheer number makes it harder for an agent to navigate without advanced context.
Completeness5/5
The tool surface provides comprehensive coverage for CRM object CRUD (including batch operations and search), associations (with label discovery), property management, workflow management (v3 and v4), enrollment lifecycle, and automation callback handling. No obvious gaps for typical HubSpot automation tasks.
Average 4.1/5 across 37 of 37 tools scored. Lowest: 2.9/5.

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

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden of behavioral disclosure. It states 'Create or update' suggesting idempotency, but does not confirm if update means overwriting existing associations or adding new ones. It also does not mention permissions (e.g., required scopes), error handling (e.g., what happens on conflict), or rate limiting. These gaps reduce transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is front-loaded with purpose, then provides a helpful reference table for default typeIds. However, the table is somewhat lengthy and could be streamlined or moved to a usage note. The description is concise enough but not optimally structured; it mixes general usage with specific examples.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 5 required parameters, no output schema, and sibling tools, the description covers key usage examples but lacks return value explanation (e.g., the created association ID or confirmation). It also does not mention that associations can be one-to-many or that the 'associationCategory' field limits the category. For a creation tool, information about the response (e.g., status, association URI) is important for the agent to know what to expect.
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?
Input schema has 100% coverage with descriptions for each parameter, so baseline is 3. The description adds limited value beyond schema: it provides a table of default HUBSPOT_DEFINED typeIds for common object pairings, which aids quick use but not essential. No parameters are explained in more depth than the schema.
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 creates or updates an association between two HubSpot CRM objects using the v4 API, and lists example link combinations (call to contact, etc.). It is specific about the resource and action. However, it does not explicitly differentiate from sibling tools like hubspot_associations_batch_create, though the singular 'create' implies single pair. Purpose is clear but could be stronger by contrasting with batch operation.
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 explicit guidance on when to use this tool versus alternatives (e.g., batch_create for multiple associations, archive to remove). The description implies direct use for single associations but does not state prerequisites, when not to use (e.g., if object types are invalid), or that associationTypes must be discovered via labels_list. Usage context is implied but not systematically addressed.
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?
No annotations are provided, so the description carries full burden. It discloses the paginated response shape and the behavior that only default properties are returned unless specified. It does not mention rate limits, authentication needs, or any side effects, but for a read-only list operation, the disclosed info is adequate.
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: two sentences and an important note. Everything is front-loaded with purpose and key behavior. Every sentence adds value without redundancy.
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 no output schema, the description explains the return shape and pagination mechanism. It covers all key aspects: supported object types, properties default, archived flag. It does not mention error responses or edge cases, but for a list tool, this is sufficient. The complexity (6 params, 1 required) is well-addressed.
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 100%, so baseline is 3. The description adds significant value by explaining how to use the `properties` parameter (e.g., 'dealname,amount,closedate') and how pagination works with `pagination.nextCursor`. This context helps the agent correctly construct requests beyond what the schema provides.
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 HubSpot CRM records for multiple object types, with specific verb 'list' and resource 'CRM records'. It lists all supported object types and mentions pagination shape. However, it does not explicitly differentiate from sibling tools like hubspot_crm_search, which might be used for filtered listing.
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 includes important usage notes about default properties and pagination, which guide correct invocation. However, it lacks explicit guidance on when to use this tool versus alternatives (e.g., search for filtering, get for single record) and does not 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full behavioral burden. It only states it returns a flat list of workflow definitions, but does not disclose that it's read-only, safe to call, or details about pagination, authentication needs, or any side effects. The lack of behavioral context is a significant gap for a tool with zero annotation coverage.
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 with two sentences that efficiently convey the tool's purpose, legacy status, and return format. Every sentence adds value without any fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a list tool with two parameters and no output schema, the description provides the basic purpose and return format ('flat list of workflow definitions'). However, it omits details about pagination behavior, ordering, and what the definitions contain. The information is adequate but not fully complete for an agent to understand all aspects of the tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents both parameters (limit and offset) with descriptions. The tool description does not add any additional meaning or context beyond what the schema provides, meeting the baseline expectation.
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 all workflows using the HubSpot Automation v3 API, with a specific verb ('List') and resource ('Workflows'). The '[LEGACY]' prefix distinguishes it from potential v4 alternatives, and it explicitly notes it's the legacy API, helping the agent differentiate it 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 Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description advises to prefer Automation v4 flows for new integrations, providing explicit when-to-use and when-not-to-use guidance. While it doesn't name the exact alternative tool, it gives clear context to avoid using this v3 API for new work.
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?
Provides max pairs and default type IDs but lacks details on error handling, idempotency, partial failures, or auth requirements. No annotations to supplement.
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?
Two paragraphs, front-loaded with key info. Could be slightly tighter but overall efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers input structure, defaults, and examples but misses return value description and error handling. For a batch tool with no output schema, these omissions are notable.
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 coverage is 100%, so schema already describes parameters. Description adds default type IDs mapping, which is helpful but not essential. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states it batch-creates associations between HubSpot object pairs, distinguishes from individual creates via 'more efficient than individual creates', and provides specific use case examples.
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?
Explicitly says when to use (e.g., after bulk import, linking multiple deals) and notes maximum 100 pairs, but does not explicitly say when not to use (e.g., single associations should use individual create).
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?
No annotations are provided, so the description must carry the full burden. It states the tool returns a list of workflows the contact is currently enrolled in, but does not disclose any behavioral traits such as side effects, rate limits, or permission requirements. For a read operation, this is minimal but acceptable.
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 two sentences long, front-loads the action and resource, and contains no redundant information. Every word adds value.
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 simple structure (single required parameter, no output schema), the description adequately explains what the tool does and returns. It could mention that results are limited to active enrollments, but it already says 'active'. Minor improvement possible but overall complete for its complexity.
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?
There is one parameter (vid) with 100% schema description coverage. The tool description adds 'HubSpot VID (contact record ID)' which matches the schema's description. Since the schema already documents the parameter, the description adds no extra value beyond confirming the context.
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 ('Get') and resource ('active workflow enrollments for a contact by HubSpot VID'), clearly distinguishing it from siblings like hubspot_enrollment_enroll (enroll) and hubspot_workflows_list (list all workflows). It precisely states the action and the scope.
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 clearly indicates when to use the tool (to retrieve enrollments for a specific contact). It does not provide explicit when-not-to-use or alternatives, but the context is clear enough given the sibling tools that perform different enrollment actions.
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?
No annotations are provided, so the description must fully disclose behavioral traits. It mentions BETA status and OAuth scope but fails to state that the operation is read-only, any rate limits, or potential 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences: first states the purpose and return value, second states the required scope. No unnecessary words, well front-loaded.
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?
For a simple tool with one parameter and no output schema, the description covers essential context: beta status, scope requirement, and key metrics returned. Minor gap: doesn't confirm it's a read operation.
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 only parameter, flowId, is fully described in the schema with coverage at 100%. The description text adds no additional meaning beyond the schema, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool retrieves performance metrics for an automation workflow, with specific examples like enrollment counts and action completion rates. This distinguishes it from sibling tools that list or get workflow details.
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?
Specifies the required 'automation' OAuth scope, which is a key prerequisite. However, it does not explicitly describe when to use this tool over alternatives or exclusion criteria.
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?
With no annotations provided, the description must fully disclose behavior. It effectively explains the effects of each hs_execution_state value (continue, continue despite failure, stop enrollment). It does not cover authentication, rate limits, or idempotency, but for a simple callback completion this is adequate.
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, well-front-loaded sentences: purpose, timing, and execution state options. Every sentence earns its place with no redundancy or fluff.
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 two parameters (one nested) and no output schema, the description covers the essential purpose and behavior. It could mention that no output is returned or that the workflow continues based on the state, but it is sufficiently complete for this tool's complexity.
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 schema already describes both parameters. The description adds value by explaining the practical meaning of the hs_execution_state enum values (SUCCESS continues, FAIL_CONTINUE continues despite failure, BLOCK stops enrollment). This goes beyond the schema's brief description.
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 identifies the verb 'complete' and resource 'async custom-action callback' within HubSpot Workflows. It specifies the version (v4 automation runtime). However, it does not explicitly differentiate this single-callback tool from its batch counterpart among siblings, reducing clarity of scope.
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 states when to call ('after your external action finishes') and explains the three possible states. However, it provides no guidance on when not to use this tool, no mention of prerequisites (e.g., having a valid callbackId), and no comparison with the sibling batch tool for multiple callbacks.
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?
Without annotations, description carries full burden. Mentions completion of callbacks but does not disclose side effects, idempotency, error handling, or permissions. Moderate transparency.
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 main action, no extraneous words. Efficient structure.
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?
Lacks output schema; description does not specify return value or success/failure behavior. Adequate for a batch completion tool but incomplete regarding results.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%; description restates schema constraints (each item needs callbackId and hs_execution_state) without adding new meaning beyond the schema. Baseline score.
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?
Clearly states the verb 'complete', resource 'async custom-action callbacks', and specifies 'in bulk'. Distinguishes from singleton sibling 'hubspot_automation_callback_complete'.
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?
Provides explicit use case ('when your external system processed several workflow enrollments concurrently') and notes input structure requirements. Lacks explicit exclusions but context is clear.
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?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It notes the BETA status, required OAuth scope, and that complex fields require external documentation. However, it does not describe what the tool returns after creation, whether it is idempotent, or what errors might occur. This is a moderate 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with four sentences. The first sentence states the core purpose, the second clarifies required vs optional fields, the third warns about complex schema, and the fourth notes OAuth scope. No superfluous content, and it is front-loaded.
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 7 parameters with 100% schema coverage and no output schema, the description covers creation intent, required fields, optional field deferral, external references for complex schemas, and auth. It lacks explicit mention of return value or error behavior, but overall it is fairly complete for a create tool.
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 100%, so baselines at 3. The description adds value by emphasizing required fields, providing a practical usage hint for the 'type' enum (e.g., CONTACT_FLOW is most common), and warning about complex recursion in enrollmentCriteria. This extra context raises the score above baseline.
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 it creates an automation workflow in HubSpot Automation v4 API, using the verb 'Create' and specifying the resource. It mentions the BETA status and references the update sibling tool for post-creation configuration, but does not explicitly distinguish from other sibling tools like list or get.
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 identifies when to use this tool (to create a workflow), notes the required fields, and points to hubspot_workflows_update for subsequent configuration. It also mentions the required OAuth scope. However, it does not provide explicit 'when not to use' guidance or compare to other create tools for different objects.
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?
With no annotations, the description carries full burden. It correctly indicates a read operation and mentions runtime variability of typeIds, but does not describe the output format, pagination, or any prerequisites beyond parameters.
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 paragraphs: one for purpose, one for usage and example. Every sentence adds value with no redundancy or unnecessary detail.
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?
For a simple list tool with two parameters and no output schema, the description covers the key aspects: purpose, usage context, an example, and a runtime warning. It could mention the return structure explicitly, but overall it is complete enough.
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 coverage is 100% with adequate parameter descriptions. The description adds value through an example mapping parameters to actual values, but does not provide significant additional semantic detail 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 action ('List'), the resource ('all available association label types'), and the scope ('between two HubSpot object types'), with an example that distinguishes it from sibling tools like hubspot_associations_create or hubspot_associations_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?
Explicitly advises using this tool 'BEFORE creating associations' and warns against hardcoding typeIds due to portal differences. While it doesn't explicitly list when not to use it, the guidance is strong and contextually relevant.
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 are absent, so the description must carry full burden. It mentions creation, return of the created record with id, and required properties per type. However, it omits error scenarios, permissions, or side effects like 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?
The description is three sentences, front-loaded with the core action, and efficiently covers required property variations and the associations option without redundancy.
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 no output schema and no annotations, the description adequately covers the tool's purpose, parameter requirements, and return value. It could be improved by mentioning error handling or limitations, but it is sufficient for basic use.
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 input schema already covers all parameters (100% coverage). The description adds value by highlighting the benefit of the `associations` parameter to avoid extra API calls, though it does not introduce new semantic details 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 it creates a new HubSpot CRM record and lists all supported object types. It distinguishes itself from sibling CRUD tools (e.g., batch create, update, get) by focusing on single-record creation and inline associations.
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 context on when to use the `associations` parameter to avoid separate API calls, but does not explicitly contrast with batch creation or other alternatives. It implies single-record creation but lacks clear '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.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description fully carries the behavioral burden. It details the irreversible nature, association movement, property precedence (primary wins), and required OAuth scopes. This exceeds basic disclosure, though rate limits or error states are not mentioned.
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 five sentences, front-loaded with the core purpose. Every sentence adds value (behavior, scopes, irreversibility). No redundant content, though minor tightening could improve conciseness.
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's complexity (merge with 2 params, no output schema, no nested objects), the description covers all necessary context: what happens to associations, property conflict resolution, archival, irreversibility, and required scopes. An agent has sufficient information to use it correctly.
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 coverage is 100% with clear parameter descriptions. The description adds emphasis on 'SURVIVING' and 'ABSORB' roles, reinforcing the schema but providing marginal extra value beyond it. Baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool merges two deal records, specifying the primary and secondary roles and exactly what happens (associations moved, properties merged, secondary archived). It distinctively identifies this as a merge operation among sibling tools like hubspot_crm_archive or hubspot_crm_update.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies when to use (when merging deals) but does not explicitly state when not to use or compare with alternatives like updating individually. It provides context on irreversibility and required scopes, but lacks explicit exclusions or sibling differentiation.
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?
With no annotations provided, the description carries the full burden. It discloses the basic behavior (enrollment) and a prerequisite, but does not mention side effects, idempotency, error cases, or return values. It is adequate but not detailed.
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 two sentences (26 words), front-loaded with the main action, and contains no unnecessary words. Every sentence adds value.
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?
For a simple mutation tool with fully described parameters, the description covers the primary action, prerequisites, and input hints. It does not describe output, but given no output schema, this is acceptable. The tool fits well among siblings.
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 coverage is 100%, so baseline is 3. The description restates the required parameters ('workflow's numeric ID and contact's email') but adds no new constraints or formatting beyond the schema, thus meeting but not exceeding the baseline.
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 'Enroll' and the resource 'a contact into a HubSpot Workflow (Automation v2)'. It distinguishes from siblings like hubspot_enrollment_unenroll by specifying the action direction, and includes prerequisites and input hints.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage context by stating the prerequisite 'The contact must exist in HubSpot'. It does not explicitly mention when not to use or compare to alternatives like hubspot_enrollment_unenroll, but the context is clear enough for a simple action tool.
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?
With no annotations, the description carries full burden. It explains the effect ('stops contact from progressing') but does not clarify if the contact is completely removed from the workflow or if the action is reversible. Nonetheless, it gives a clear behavioral summary.
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 primary action. No extraneous information; every word serves a purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Explicitly states it removes all associations between two HubSpot CRM objects using v4 API and clarifies it does not delete the objects themselves. Distinguishes from sibling by mentioning the batch archive endpoint for removing specific labeled associations.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit guidance on when to use this tool (remove all associations) and when not (for specific labeled associations, use batch archive). Clearly directs to alternative endpoint.
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?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It reveals the 100-record limit, per-record error returns, optional associations, and the hs_timestamp requirement for engagements. However, it does not specify whether the batch operation is fully atomic or handles partial failures, which would be useful for a mutation tool. This gap prevents a 5.
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 four sentences, each earning its place: 1) core purpose and batch size, 2) applicability and input structure, 3) special requirement for engagements, 4) return behavior. No fluff, well-front-loaded.
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 tool's complexity (batch creation with optional associations), no output schema, and no annotations, the description covers the key aspects: limit, input format, special requirement, and return type. It could be more explicit about output structure (e.g., whether IDs are returned) but is still quite complete for a batch creation tool.
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 100%, so the baseline is 3. The description adds value beyond the schema by highlighting the batch limit, the engagement timestamp requirement, and the atomic creation of associations. This additional context justifies a 4.
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 creates up to 100 HubSpot CRM records in a single request, applicable to all object types. It distinguishes from siblings like hubspot_crm_create (single record) and other batch operations (read, update, upsert, archive) by specifying batch creation and the 100-record limit.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides usage context: it's for creating records in bulk, applies to all object types, and notes a special requirement for engagements (hs_timestamp). While it doesn't explicitly contrast with alternatives, the sibling tools list and the description's focus on batch creation make the usage clear. A score of 4 is appropriate due to lack of explicit 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.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, description reveals key behaviors: returns 404 if missing or archived, properties parameter required for custom fields, archived parameter toggles record type. Good coverage but does not explicitly state read-only nature.
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 plus an emphasized note. Front-loaded with purpose, then key usage tips. No extraneous information. Efficient and clear.
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 purpose, all object types, required parameters, important optional parameter, error handling. Lacks response format description and usage of `associations` but overall adequate for a simple get tool with no output schema.
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 100%, baseline 3. Description adds value by emphasizing `properties` with example and explaining default behavior. Also clarifies `archived` and 404 implications. Does not add much for `associations` but overall enhances understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Explicitly states 'Retrieve a single HubSpot CRM record by its ID' and 'Works with all object types'. Clearly distinguishes from sibling tools like list, search, and batch read by specifying single record retrieval.
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?
Provides important guidance: always specify `properties` for non-default values and use `archived=true` for archived records. Mentions 404 error behavior. Does not explicitly compare to alternatives but context is 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?
No annotations are provided, so the description carries the full burden. It discloses rate limits, indexing latency, max results, and property requirements. However, it does not mention error behavior or response format, which would be helpful for a complete behavioral picture.
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 and well-structured: a clear lead sentence followed by bullet-pointed important notes. Every sentence adds value, 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.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (search with filtering, sorting, paging) and no output schema, the description covers essential behaviors like rate limits, latency, max results, and property specification. It could be improved by explicitly stating the response format (list of records), but overall it is complete enough for an AI agent to use correctly.
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?
All 7 parameters have schema descriptions (100% coverage), so baseline is 3. The tool description adds context about filter group structure and usage (e.g., OR-ed groups, AND-ed filters, max counts) but does not add significant new semantics per parameter beyond what the schema already provides.
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 searches HubSpot CRM records with filters, sorts, and full-text query, and applies to all object types. It distinguishes itself from sibling tools like hubspot_crm_get by explicitly recommending that tool for read-after-write.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit usage guidelines including rate limits (~5 req/s), indexing latency (do not use after create/update), max results (10,000), and the need to specify properties. It also recommends an alternative tool (hubspot_crm_get) for read-after-write scenarios.
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?
No annotations provided. The description discloses important behaviors: naming constraints (lowercase underscores) and that name is immutable after creation. It lists common type/fieldType combinations.
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 with a main sentence, a helpful table of common combinations, and a key note, all front-loaded with 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 12 parameters (6 required) and no output schema, the description covers the creation intent, parameter combinations, and naming rules. However, it could mention return value or error conditions.
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 100% with descriptions for all 12 parameters. The description adds value beyond the schema by explaining common type+fieldType combinations and naming convention.

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 says 'Use this to extend deal, contact, company, or other object records' which indicates when to use, but doesn't explicitly state when not to use 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?
With no annotations provided, the description carries the full burden. It discloses that this is a PUT operation that replaces the entire workflow, resets omitted fields to defaults, and requires the 'automation' OAuth scope. This sufficiently communicates the tool's mutation 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 three sentences long, front-loading the core purpose ('Fully replace'), then providing behavioral and prerequisite guidance. 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 essential operation, prerequisites, and behavioral traits. However, it does not describe the return value or response format, which is notable given the lack of an output schema. Still, the description is adequate for a mutation tool with clear documentation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, but the description adds critical meaning: 'Fields not included in the request body will be reset to their defaults.' This clarifies parameter behavior beyond the schema, explaining the effect of omission. The suggestion to use get first also adds value.
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 states 'Fully replace an existing automation workflow' via a PUT operation, clearly specifying the verb and resource. It differentiates from sibling tools like hubspot_workflows_get by advising to fetch current state before updating.

Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly says to use hubspot_workflows_get first to fetch current state, providing clear context. It explains the full replacement behavior but does not explicitly state when not to use this tool.
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?
The description fully discloses behavioral traits: it's a soft-delete (not permanent), records can be retrieved with archived=true, returns HTTP 204 on success, and provides alternative for permanent deletion. Since no annotations are provided, the description carries the full burden and excels.
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 sentences: first defines action, second explains behavior and retrieval, third gives response and alternative. Front-loaded with purpose, 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?
For a simple 2-parameter tool with no output schema, the description covers all essential aspects: action, behavior (soft-delete vs permanent), retrieval method, response format, and alternative. Complete for agent decision-making.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the baseline is 3. The description adds that it applies to 'all object types,' which is already implied by the enum in the schema. No significant additional semantic value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5

Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It discloses that the tool is a helper that performs a single operation with inline associations, default association type IDs, and overrides. It does not explicitly mention idempotency, error behavior, or return value, but covers essential behavioral aspects well.
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?
Approximately 4-5 sentences, front-loaded with main purpose, then prerequisites, then details. No redundant information. Every sentence contributes to clarity and is well-structured.
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 complexity (17 parameters, 3 required, nested objects, no output schema), the description covers prerequisites, association details, and scopes. It lacks explicit mention of return values or behavior on failure, which would improve completeness, but overall it is reasonably comprehensive.
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 100%, so baseline is 3. The description adds value by explaining the purpose of additionalProperties and the override parameters for association type IDs, which are not fully detailed in the schema. This enhances understanding beyond the built-in descriptions.
