MCP-Ambari-API
Server Quality Checklist
Latest release: v3.7.5
- Disambiguation3/5
Most tools have distinct purposes, but there is significant overlap in some areas. For example, get_service_status, get_service_details, and get_service_components all relate to service information, which could cause confusion. Additionally, get_alerts_history and get_current_alerts (deprecated) overlap, though the deprecation helps. The tools are generally scoped to different resources or actions, but the service-related tools are ambiguous.
Naming Consistency4/5The majority of tools follow a consistent verb_noun pattern (e.g., get_cluster_info, list_hosts, restart_service), which is clear and predictable. However, there are a few deviations like hdfs_dfadmin_report and list_ambari_metric_apps that use different conventions, slightly breaking consistency. Overall, the naming is mostly uniform and readable.
Tool Count3/5With 26 tools, the count is on the higher side for an Ambari API server, which might feel heavy but is reasonable given the domain's complexity. It covers monitoring, management, and metrics, but some tools could potentially be consolidated (e.g., service-related tools). The count is borderline, as it approaches the upper limit of what's typical for a well-scoped server.
Completeness4/5The tool set provides comprehensive coverage for Ambari cluster management, including monitoring (alerts, metrics, requests), service control (start/stop/restart), and information retrieval (cluster, hosts, services, users). Minor gaps exist, such as no explicit tool for creating or deleting services or users, but core operations are well-covered, and agents can likely work around these omissions.
Average 4/5 across 26 of 26 tools scored. Lowest: 2.8/5.

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 must convey behavioral traits. While 'report' implies a read operation, there is no explicit mention that it is non-destructive, no disclosure of authentication needs, rate limits, or potential side effects. The description's brevity leaves significant behavioral ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, which is concise, but it lacks structure. While it is not verbose, it does not efficiently front-load key details; it is under-specified rather than concisely informative.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of a tool that produces a report from Ambari metrics, the description is too minimal. It does not explain what the report contains beyond 'capacity and DataNode', does not describe parameter effects, and omits any usage context or prerequisites. The existence of an output schema partially compensates, but overall the description is incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage, and the description does not mention any of the two parameters (cluster_name, lookback_minutes). It fails to add any meaning or context beyond the parameter names and types, leaving the agent unable to understand how to use them.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool produces a DFSAdmin-style capacity and DataNode report using Ambari metrics. The verb 'produce' and specific resource 'DFSAdmin-style capacity and DataNode report' differentiate it from sibling tools which deal with configurations, requests, alerts, and services.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It does not mention any prerequisites, contexts, or exclusions for usage, leaving the agent without criteria to decide if this tool is appropriate.
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 exist, so the description bears full responsibility for behavioral disclosure. It only mentions the constraint 'exact metric names only' but does not address data volume limits, rate limiting, authentication requirements, or other behavioral traits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, concise but overly brief. It front-loads the action but lacks necessary detail. Given the tool's complexity, the sentence is too short to be effective.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite the presence of an output schema, the description fails to provide context for the numerous parameters or the exact nature of the returned metrics. It covers only the basic purpose, leaving many aspects unexplained.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage and 12 parameters (including optional ones like app_id, hostnames, duration), the description does not explain any parameter. The agent must infer parameter usage from names alone, which is insufficient.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states 'Fetch time-series metrics (exact metric names only) from Ambari Metrics,' which clearly identifies the verb (fetch), resource (time-series metrics), and constraint (exact metric names). It distinguishes itself from sibling tools like 'list_ambari_metrics_metadata' and 'list_ambari_metric_apps'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives, such as listing metrics first or using other query tools. The description simply states what it does without contextual usage advice.
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, and the description only states it retrieves metadata, lacking disclosure on permissions, rate limits, pagination, or response structure beyond what the output schema offers.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence with no waste, but could include more detail without sacrificing conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 6 parameters and no schema descriptions, the description is too brief; it does not explain what metric metadata is or how filters affect results.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description does not explain any of the 6 parameters, failing to add meaning beyond parameter names and types.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'retrieve', resource 'metric metadata', and source 'Ambari Metrics service', distinguishing it from sibling tools like query_ambari_metrics and list_ambari_metric_apps.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does 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; the description only mentions optional filters without providing context on preferred use cases.
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 burden. It implies a read-only operation by stating it returns data, but does not explicitly confirm it is non-destructive or disclose any behavioral traits beyond the basic output.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with only 9 words, conveying the core functionality without redundancy. However, it could be expanded slightly to improve clarity on parameters.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple tool with three parameters and an output schema, the description lacks detail on parameter behavior and usage context. It does not address when to use refresh or limit, leaving gaps for the agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description must compensate but only partially addresses one parameter: 'optionally with metric counts' hints at include_counts. The refresh and limit parameters are not explained at all.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states that the tool returns 'discovered AMS appIds' and allows including metric counts. It uses a specific verb 'Return' and identifies the resource, but does not explicitly differentiate from sibling tools like list_ambari_metrics_metadata or list_common_metrics_catalog.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives, nor any prerequisites or context. It simply describes the output without indicating appropriate use cases.
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 carries the full burden. It only states the basic function and does not disclose any behavioral traits such as how null appId is handled or safety.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is one concise sentence, but it lacks structure and does not cover the tool's complexity. It is front-loaded but under-specified.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the five parameters and output schema, the description is too brief. It fails to explain how to use parameters effectively, making the tool incomplete for an agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage and no elaboration in the description, the agent is left to infer the meaning of parameters like search, limit, min_score, and include_description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it lists supported metrics per appId with exact names only, distinguishing it from similar tools like list_ambari_metric_apps.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for retrieving supported metrics by appId but provides no explicit guidance on when to use this tool versus siblings like list_ambari_metrics_metadata.
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 implies a read-only operation ('Get detailed information') but does not explicitly state safety or side effects. With no annotations, the burden is on the description; it partially discloses the return content but omits auth requirements, rate limits, or potential 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.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, with a brief introductory sentence followed by structured sections for Args and Returns. It is front-loaded with the core purpose and uses minimal, efficient language.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema, the description does not need to detail return values, but it lists the categories of information. The tool is simple with one parameter, and the description covers its basic usage. However, it lacks any mention of error cases or prerequisites.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage, but the description's 'Args' section explains that user_name is 'The username to retrieve details for'. This adds meaningful context beyond the bare schema type, compensating for the lack of schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Get detailed information about a specific user' with a specific verb and resource. It lists the categories of information returned (profile, permissions, authentication sources). However, it does not distinguish itself from the sibling tool 'list_users', which likely retrieves multiple users.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does 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 like 'list_users'. The description only states the function and requires a user_name, but does not explain scenarios or contexts for use.
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 exist, so the description must carry the full burden. It only states it returns a formatted list, but does not mention read-only nature, authentication needs, 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.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Two brief sentences that are front-loaded with the action and scope, containing no extraneous information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a parameterless list tool with an output schema, the description adequately covers its purpose. It could mention that it is a read operation, but overall it is complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameters exist, so schema coverage is 100%. The description adds no parameter info, but none is needed. Baseline 4 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'List all users in the Ambari system,' which is a specific verb+resource. It distinguishes from sibling 'get_user' by implying listing all vs. a single user.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does 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 like 'get_user' is provided. The usage is implied but not clarified.
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 must carry the full burden. It mentions real-time retrieval and state information but does not explicitly declare the tool as read-only or discuss side effects, permissions, or error behavior beyond a generic failure message.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with sections and bullet points but is somewhat verbose, repeating concepts like 'status' and 'state'. It could be more concise without losing clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple retrieval tool with one parameter, the description covers purpose and parameter adequately. However, it does not address when to use this tool versus similar siblings (e.g., get_service_details), and the output description is vague despite an output schema being present.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The parameter service_name is clearly described with examples (e.g., 'HDFS', 'YARN', 'HBASE'), adding practical value beyond the schema which lacks a description field. Schema description coverage is 0%, so the description compensates well.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it retrieves status information for a specific service in an Ambari cluster, with a specific verb and resource. It distinguishes itself from sibling tools like get_service_details or get_cluster_services by focusing on real-time status and state.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes 'Required Usage Scenarios' such as when users ask about specific service status, troubleshooting, and monitoring. However, it does not explicitly compare to sibling tools, leaving some ambiguity about when to use this tool over others like get_service_details.
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 present, so the description carries full burden. It implies a read operation via 'retrieve', but does not disclose any additional behavioral traits such as rate limits, authentication requirements, or side effects. The deprecation note is helpful but not sufficient for full transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences long, front-loading the purpose and immediately providing deprecation context. Every sentence earns its place with no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
An output schema exists, so return values are documented. However, the description lacks parameter explanations and does not clarify what 'current alerts' means or how filtering works. Given zero annotation coverage, the description is only partially complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, meaning the input schema provides no parameter descriptions. The tool description does not explain any of the 7 parameters (e.g., cluster_name, service_name, state_filter), leaving the agent without guidance on how to use them.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Retrieve current alerts from Ambari cluster', specifying the action and resource. It also distinguishes from sibling by noting deprecation in favor of get_alerts_history.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states deprecation and provides the alternative get_alerts_history with mode='current', guiding the agent to prefer the replacement while acknowledging backward compatibility.
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 provided; description implies read-only behavior but does not explicitly state idempotence, safety, or side effects. Mentions 'formatted output for LLM automation' but no permission or rate limit context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5Is the description appropriately sized, front-loaded, and free of redundancy?
Structured with sections but contains redundancy (e.g., 'Retrieves detailed status and configuration information' repeated in opening and Core Functions). Could be tighter.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Single-parameter tool with existing output schema; description covers success and failure return types. Lacks details on output fields but is acceptable given output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% description coverage, but description adds examples ('HDFS', 'YARN', 'HBASE') and clarifies purpose beyond the bare schema type 'string'.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Retrieves detailed status and configuration information for a specific service' and differentiates from siblings like get_service_status and get_service_components by emphasizing comprehensive details.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit 'Required Usage Scenarios' (detailed info requests, troubleshooting) but lacks comparative guidance on when to use alternatives like get_service_status.
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 provided, so the description carries the full burden. It discloses that the tool returns hardware specs, state, metrics, components, and formatted output. It does not explicitly state read-only nature or authentication needs, but the behavior is well enough described for most cases.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with sections like Tool Role, Core Functions, Required Usage Scenarios. However, some redundancy exists (e.g., Core Functions repeats purpose). The description is front-loaded with the primary action.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers both modes (with and without host_name). Mentions return contents (hardware, metrics, state, components). An output schema exists so precise fields are not needed. For a single-parameter tool, this is sufficiently complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% (no description on host_name param). The description adds significant value by explaining host_name is optional with an example value, and clarifies its role in filtering. This compensates for the missing schema description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Fully stated: 'Retrieves detailed information for a specific host or all hosts in the Ambari cluster.' Uses a specific verb and resource, and distinguishes from siblings like list_hosts (which likely only lists names) by specifying scope and detail level.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides clear scenarios in 'Required Usage Scenarios' (e.g., when users request host details, auditing). Lacks explicit when-not-to-use or alternative sibling recommendations, but the context is clear enough for an agent to infer appropriate 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?
No annotations are provided, so the description bears the full burden. It explains the tool returns status, progress, timing, and is intended for automation. It does not disclose authorization needs or side effects, but for a read-only operation 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.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with sections, but somewhat verbose. It could be more concise without losing key information. Overall it is clear and logically organized.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema, the description adequately outlines return values (status, progress, timing). It lacks details on error conditions or retry logic, but is sufficient for a simple status retrieval tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description explains the 'request_id' parameter's purpose and type (int), but the input schema declares it as a string. This contradiction could mislead an agent. Since schema coverage is 0%, the description adds some meaning, but the inconsistency reduces reliability.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Retrieves the status and progress of a specific Ambari request operation', using a specific verb and resource. It distinguishes itself from siblings like 'get_active_requests' and 'get_request_tasks' by focusing on a single request by ID.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The 'Required Usage Scenarios' section lists clear conditions for use, such as when users ask for status or during monitoring. However, it does not explicitly contrast with sibling tools like 'get_request_tasks' that might be more appropriate for detailed task-level information.
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. It describes the action ('initiate Ambari request'), return types (success with request info, failure with error message), and mentions 'safe and monitored startup'. However, it does not disclose potential side effects, authentication needs, or prerequisites (e.g., service must be stopped). This is adequate but not highly transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with sections (Tool Role, Core Functions, etc.), making it easy to scan. It is somewhat lengthy but each section adds useful information. Could be slightly more concise without losing clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple single-parameter tool, the description covers the core action, return types, and usage scenarios. It does not mention output schema details (though context indicates an output schema exists), but the description already explains the return format. It lacks prerequisites or edge cases, but overall is sufficiently complete given the tool's simplicity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has one required parameter (service_name) with no description. The description adds value by providing examples ('HDFS', 'YARN', 'HBASE') and a clear purpose. With schema description coverage at 0%, this compensation is strong, though it could include format constraints or allowed values.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it 'Starts a specific service in the Ambari cluster' using a specific verb and resource. The 'Core Functions' and 'Required Usage Scenarios' further reinforce the purpose and differentiate it from sibling tools like stop_service, restart_service, and start_all_services.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
It explicitly lists required usage scenarios (e.g., when users request to start a service, recovering stopped services). It does not directly state when not to use, but the naming of sibling tools implies alternatives (e.g., start_all_services for bulk). The guidance is clear but could be slightly more explicit about 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?
With no annotations provided, the description discloses the tool's bulk stopping behavior and return value (request info or error message). However, it does not mention the destructive nature (all services stopped), whether it requires confirmation, or any prerequisites like cluster state. This leaves some behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is structured with clear sections (role, core functions, usage scenarios) and is front-loaded with purpose. Some phrases are slightly redundant (e.g., 'Dedicated tool' and 'bulk stopping'), but overall it is concise and well-organized.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given 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 (likely documented elsewhere), the description covers the core behavior, return value, and usage scenarios. It doesn't mention limitations or side effects beyond what is implied, but for a simple action tool, it is sufficiently complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, and the input schema is empty with 100% coverage. The description does not need to add parameter meaning, and it properly avoids mentioning non-existent parameters. Baseline 4 is appropriate.

However, it does not explicitly state when to use this tool over alternatives or when not to use it. Since it is the sole tool for this purpose, the guidance is adequate but lacks explicit exclusion or 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?
Describes stop-then-start process, wait for completion, and return info. No annotations provided, but description covers key behavioral aspects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Concise yet comprehensive with clear sections (Tool Role, Core Functions, Required Usage Scenarios, Args, Returns) and no unnecessary text.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers all necessary context: parameters, behavior, return values, and usage scenarios. Could be slightly more complete regarding error details, but adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% description coverage, but description provides examples and explanation for host_name and component_name, adding value beyond schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states 'Restarts a specific component on a specific host' with verb and resource, and distinguishes from siblings like restart_service, start_host_component, etc.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly lists when to use (component restart requests, recovery, config changes) and implies when not to via sibling 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?
No annotations exist, so description carries full burden. It thoroughly explains the two modes, filtering capabilities, pagination, time context, and that it provides current time for LLM calculations. It is transparent about behavior without contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with clear sections (Tool Role, Core Functions, Usage Scenarios, Args, Returns) and front-loaded key info. However, it is somewhat verbose and has minor redundancy (e.g., first line repeated in Core Functions).
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 14 parameters, no annotations, and an output schema, the description covers all aspects: modes, filtering, pagination, time context, output formats, and return value description. It is complete and leaves no critical gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but the description lists all 14 parameters with explanations, mode-specific applicability, and defaults. It adds significant meaning beyond the schema, especially for mode-dependent parameters like maintenance_state, from_timestamp, to_timestamp, page_size, and format.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it retrieves current alerts or alert history from Ambari cluster, with two distinct modes. It distinguishes itself from sibling get_current_alerts by also handling history. The verb 'retrieve' and resource 'alerts' are specific.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit required usage scenarios for both current and history modes, and lists when to use based on user queries. However, it does not include exclusions or when not to use this tool versus siblings like get_current_alerts.
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 details the behavior: listing tasks with filtering capabilities and return format. However, it does not explicitly state that the tool is read-only or mention authentication needs. Since annotations are absent, the description carries full burden but is still thorough.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with sections and front-loaded purpose. However, it is fairly long; while every sentence is useful, slight trimming could improve conciseness without losing value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (multiple filters, use cases), the description covers all necessary aspects: parameters, return format (table vs error), and usage scenarios. No output schema is needed as the description explains the output.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description fully compensates by explaining each parameter: request_id as integer string, status_filter with exact statuses and 'not:' prefix logic, host_filter as substring. This adds critical meaning beyond the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves task-level details for a specific Ambari request with a host-by-host breakdown, and it explicitly differentiates from the sibling tool 'get_request_status' which provides summary-level data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The 'Required Usage Scenarios' section explicitly lists when to use this tool, such as debugging partially-failed operations or when request progress is near 100% but incomplete. It provides clear context for use vs. alternatives.
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?
No annotations are provided, so the description fully carries the burden. It details behavioral traits including safe and monitored shutdown, return of request info for progress tracking, and clear success/error messages.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with sections like [Tool Role] and [Core Functions], but it is somewhat verbose. It front-loads the purpose effectively.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the single parameter and presence of output schema (mentioned in description), the description fully explains the return value structure and covers all necessary context for a stop operation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single parameter service_name has 0% schema description coverage. The description adds meaning by stating it is the name of the service to stop and provides examples (e.g., HDFS, YARN).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it stops a specific service in the Ambari cluster, using the verb 'stops' and the resource 'service'. It distinguishes from siblings like start_service and restart_service.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly lists required usage scenarios such as when users request to stop a service or during maintenance, providing clear guidance on when 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.
