Server Quality Checklist

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

Latest release: v1.1.0
Disambiguation5/5
Every tool targets a distinct entity or specific sub-aspect of an entity (e.g., get_incident vs. get_outlier_incident, list_schedule_v3_rotations vs. list_schedule_v3_rotation_events). No two tools have overlapping purposes.
Naming Consistency5/5
All tools follow a consistent verb_noun pattern using 'get_' for single resources and 'list_' for collections. There is no mixing of camelCase or other conventions.
Tool Count2/5
63 tools is far above the typical well-scoped range (3-15). While the tool count covers many PagerDuty entities, the sheer number makes the surface difficult to navigate and suggests insufficient consolidation.
Completeness1/5
The server is entirely read-only with no create, update, delete, or action tools (e.g., acknowledge_incident, create_service). For an incident management platform, this is a severe gap that prevents agents from performing any operational actions.
Average 3.9/5 across 63 of 63 tools scored. Lowest: 2.6/5.

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?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds no additional behavioral context such as authentication requirements, rate limits, or side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very brief and to the point. However, it could include more detail without becoming verbose. The structure is front-loaded with purpose, then Args and Returns sections.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 2 required parameters and an output schema, the description lacks completeness. It doesn't describe the return object structure, potential error conditions, or the relationship to other schedule entities.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% with no descriptions on parameters. The description merely repeats the parameter names ('schedule_id', 'custom_shift_id') without adding format, validation, or source information.
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 'Get a specific custom shift within a v3 schedule.' This provides a specific verb ('Get') and resource ('custom shift'), and implicitly distinguishes it from the sibling list tool 'list_schedule_v3_custom_shifts' which retrieves multiple shifts.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like 'get_schedule_v3_rotation' or 'get_schedule'. The description lacks context about prerequisites or typical workflows.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the agent knows this is a safe read operation. The description adds no behavioral information beyond what the annotations provide, such as rate limits, authentication needs, or return value structure. Minimal value added.
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 concise: one sentence for the purpose, followed by a clear args/returns structure. Every sentence serves a purpose without unnecessary fluff. However, it could be slightly more structured by separating narrative from docstring.
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's simplicity (single required parameter, output schema exists), the description covers the basics: get by ID and return details. It does not mention related tools for obtaining IDs or any side effects. With annotations covering safety, it is minimally adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description must compensate, but it only restates the parameter as 'The ID of the escalation policy to retrieve,' which adds little beyond the schema's title 'Policy Id.' No additional constraints or format details are provided.
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 'Get a specific escalation policy,' specifying the verb 'Get' and the resource 'escalation policy.' This distinguishes it from sibling tools like list_escalation_policies, which performs a different operation. However, it lacks additional context about what an escalation policy is.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., needing a policy ID from list_escalation_policies) or when not to use it. The only implied usage is that it requires a policy_id, but no explicit usage context is given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint, idempotentHint, and destructiveHint. The description adds no extra behavioral context such as permissions, rate limits, or response handling.
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 appropriately short but uses a docstring format with 'Args' and 'Returns' sections that add minimal value. It could be more concise.
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 low complexity (1 parameter, output schema exists), the description is just adequate. It does not explain return values or error cases, but the output schema covers that.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description merely restates 'The ID of the incident workflow to retrieve,' adding no deeper meaning or constraints beyond the schema property name.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Get a specific incident workflow,' using a specific verb and resource. It distinguishes from sibling tools like 'list_incident_workflows' and 'get_incident' by specifying a single workflow.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. It does not mention prerequisites, exclusions, or comparisons to other incident-related tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true, so the description adds no additional behavioral insight (e.g., no mention of side effects, permissions, or response details beyond using the parameter names).
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 succinct and front-loaded with the core purpose. However, it could include a brief sentence about when to use it without being verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While an output schema exists and the tool is simple, the description fails to link to necessary IDs (e.g., from list endpoints) or explain the hierarchical relationship among schedule, rotation, and event, reducing completeness for new users.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but the description merely repeats parameter names with generic phrases like 'The ID of the v3 schedule' without adding formats, origins, or examples. This provides minimal semantic help over the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Get a specific event within a v3 schedule rotation,' specifying the verb (get), resource (event), and context (v3 schedule rotation). It effectively distinguishes from sibling tools like list_schedule_v3_rotation_events and other get_ tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., listing events or getting a rotation). The description does not provide any when-to-use, when-not-to-use, or prerequisite instructions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true, indicating safe read behavior. The description's 'Get details' aligns with this, but it adds no extra behavioral context (e.g., error handling, rate limits). Since annotations carry the transparency burden, a 3 is appropriate for not contradicting and providing basic alignment.
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 a clear structure: one sentence for purpose, followed by Args and Returns sections. Every sentence is necessary, and there is no wasted text.
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's simplicity (1 parameter, output schema present), the description is minimally adequate. However, the context includes many sibling tools for orchestration retrieval, and this description does not clarify when to use this specific variant, reducing completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The only parameter, orchestration_id, has 0% schema description coverage. The description's 'The ID of the event orchestration to retrieve' merely restates the parameter name without adding format, source, or validation rules. With no compensation for low coverage, the parameter semantics are minimal.
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 explicitly states 'Get details for a specific event orchestration,' conveying verb (Get) and resource (event orchestration) clearly. However, it fails to differentiate from sibling tools like get_event_orchestration_global or get_event_orchestration_router, which retrieve similar but distinct orchestration types.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage when you have an orchestration_id, but it provides no guidance on when not to use this tool or when to use alternative orchestration retrieval tools. Sibling tools cover different orchestration scopes, yet no exclusions or recommendations are given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint, idempotentHint, and destructiveHint, which already convey safety. The description adds only the return format (JSON string), providing minimal extra behavioral context beyond what annotations offer.
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 sentences, but the second sentence is somewhat redundant. Nevertheless, the description is short and front-loaded with the main purpose.
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 parameterless list tool with an output schema, the description is adequate in covering the basic function and return type. Lacks details about what constitutes a business service, but not critical given the simplicity.
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?
No parameters, so schema coverage is trivially 100%. Description mentions the return format (JSON string), adding value beyond the empty 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?
Description states 'List all business services' which clearly indicates the action and resource. However, it does not explicitly differentiate from sibling tools like 'list_services', relying on the name for distinction.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives or any context about prerequisites. Missing information on typical use cases or limitations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint=true, idempotentHint=true, destructiveHint=false, which fully convey the behavioral profile. The description adds no additional behavioral context beyond restating 'Get details'.
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 short and front-loaded, but includes an 'Args' and 'Returns' section that largely duplicates schema and is not needed. It could be more concise by omitting these structural elements.
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 simple tool with one parameter and an existing output schema, the description is minimally adequate but lacks parameter semantics and does not leverage the output schema (though not required). It fails to provide distinct guidance from its sibling tools.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It merely lists 'setting_id' without any additional meaning, such as format, source, or constraints. This is insufficient for a parameter that is not self-explanatory.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Get details for a specific alert grouping setting,' which is a specific verb+resource. It distinguishes from sibling tool 'list_alert_grouping_settings' which lists all settings, and other get tools target different resources.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage when needing details for a specific setting by ID, but it does not explicitly mention when to use this vs alternatives like 'list_alert_grouping_settings' or provide excluding conditions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds the return of LogEntry details, but this is also covered by the output schema. No additional behavioral context is provided.
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 short and front-loaded with the main sentence. It includes structured Args and Returns sections, but could be slightly more streamlined.
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 simple one-parameter tool with an output schema, the description is mostly adequate. However, it lacks details on error handling (e.g., if ID not found) or prerequisites, leaving some gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. The description mentions log_entry_id in Args but only as 'The ID of the log entry,' which adds minimal meaning beyond the property title 'Log Entry Id'.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Get a specific log entry by ID,' which is a specific verb+resource combination. It distinguishes from sibling tools like list_log_entries that retrieve multiple entries.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives (e.g., list_log_entries). It only states the action without context for selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false. Description adds no significant behavioral context beyond 'Get', which is consistent. No contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Short, structured with Args/Returns. No fluff, but could be slightly more concise with a single line.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Adequate for a simple get tool with an output schema. Missing explanation of query_model options and when to use include. Satisfies minimum requirements.
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?
Incident_id is described clearly but query_model only says 'Optional query parameters'. The input schema already contains detailed descriptions for the nested include field. Description adds minimal value over 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?
Description explicitly states 'Get a specific incident', clearly identifying the action and resource. This distinguishes it from siblings like list_incidents which retrieve multiple incidents.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., list_incidents for multiple, or other get_* tools). Usage must be inferred from context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is clear. The description adds only a trivial 'Returns: The override' which is redundant given the output schema. No additional behavioral traits (e.g., error cases, rate limits) are disclosed. With annotations covering the basics, the description adds minimal value beyond a score of 3.
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 reasonably concise at 8 lines, with clear sections (Args, Returns). However, the 'Returns: The override' line could be omitted since it repeats the obvious. No fluff, but slightly verbose for the minimal content.
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 presence of annotations and an output schema, the description is minimally complete for a simple get-by-ID operation. However, it fails to distinguish from related sibling tools (e.g., get_schedule_v3_rotation) or provide context on when this tool is appropriate versus similar tools. The description is adequate but not thorough.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage, so the description must compensate. It does add a bit: it states 'schedule_id: The ID of the v3 schedule' and 'override_id: The ID of the override', which clarifies the context slightly beyond the schema titles. However, this is still minimal and doesn't provide format or syntax details. Baseline for 0% coverage is low, and the description barely meets it.
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 ('Get'), the resource ('a specific override'), and the context ('within a v3 schedule'). This distinguishes it from sibling tools like list_schedule_v3_overrides (list) and get_schedule_v3_rotation (different resource).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. For example, it doesn't mention that this tool is for retrieving a single override by ID, while list_schedule_v3_overrides should be used to browse overrides. The description lacks any when-to-use or when-not-to-use context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the description adds value by specifying the return format ('JSON string with relationships list'). No other behavioral traits disclosed, which is acceptable given the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Very concise: a single sentence for purpose, then structured Args and Returns. No wasted words, front-loaded with purpose. Excellent structure.
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 getter tool with one parameter and an output schema (not shown), the description is fairly complete. It explains the return type and parameter. Could elaborate on what 'relationships' represent, but overall sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It explains 'service_id: The ID of the technical service', which adds meaning beyond the schema title but is basic and does not detail format or source. Adequate for a single required parameter.
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 verb 'Get' and resource 'dependencies for a technical service'. It is specific, but does not explicitly differentiate from the sibling tool 'get_business_service_dependencies', relying on the name for distinction.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. The sibling list includes 'get_business_service_dependencies' as a clear alternative, but the description does not mention it or provide any usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint. The description adds no additional behavioral context such as authentication requirements, rate limits, or side effects. It is adequate but does not enhance transparency beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise: two sentences for purpose and one line for the argument. It is front-loaded with the main action, no wasted words.
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?
With one parameter and an output schema, the description is minimally complete. It states what it returns ('The service orchestration configuration') but does not elaborate on the structure or give usage examples. The output schema can fill the gap, so a score of 3 is appropriate.
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 0% (no parameters documented in schema), so the description must compensate. It explains the sole parameter 'service_id' as 'The ID of the service to retrieve the orchestration configuration for', which adds minimal meaning beyond the schema title 'Service Id'. This is a basic paraphrase, not rich semantics.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Get', the resource 'Service Orchestration configuration', and the scope 'for a specific service'. This distinguishes it from sibling tools like get_event_orchestration (general) and get_event_orchestration_global (global).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It does not mention when not to use it, prerequisites, or compare to other orchestration tools in the sibling list.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, indicating a safe read. The description merely restates the return type (StatusPagePost details) without adding behavioral traits like authentication needs, rate limits, or response format details beyond what the output schema provides.
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 concise and well-structured with an Args block. However, it could be slightly more streamlined by removing the boilerplate 'Returns' line since the output schema exists. Still, every sentence provides value.
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 presence of an output schema and clear parameter descriptions, the tool is functionally complete. However, with over 30 sibling tools, additional context about when to use this retrieval versus other get functions would enhance completeness.
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?
The description adds comprehensive parameter explanations for all three parameters, despite the schema having 0% coverage. It clarifies the meaning of status_page_id, post_id, and query_model, including example usage for query_model ('e.g., include related resources'). This fully compensates for the missing schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states 'Get a Post for a Status Page by Status Page ID and Post ID,' using a specific verb and resource. It distinguishes itself from sibling tools like list_status_page_post_updates and list_status_page_impacts by focusing on a single post retrieval.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. The description does not provide context for when to choose get_status_page_post over other get tools (e.g., get_incident, get_service) or list tools. No exclusions or prerequisites are mentioned.
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 adds that the operation supports optional filtering and returns a list, which aligns with the annotations (readOnlyHint, idempotentHint, destructiveHint). It does not contradict annotations, but it also does not add significant behavioral context beyond what annotations already imply.
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 short and front-loaded with the purpose. It avoids unnecessary words, but could include more detail (e.g., default limit, filter options) without becoming verbose.
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 basic operation and return type, but does not mention pagination, default values, or the specific filtering options available. Given the presence of an output schema and annotations, the description is adequate but not comprehensive.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description mentions 'query_model: Optional filtering parameters' without elaborating on its structure or the available filters (limit, status_page_type). The schema provides descriptions for the sub-parameters, so the description adds minimal value. The 0% schema description coverage context suggests the tool description itself does not detail parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'List' and the resource 'Status Pages', which is a specific and accurate purpose. It distinguishes from sibling tools that list other resources or perform other actions.
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 does not provide explicit guidance on when to use this tool versus alternatives. While the purpose is clear, there is no mention of use cases, exclusions, or comparisons with sibling 'list_' tools for related entities like impacts or severities.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true, so the description's contribution is minimal. It adds that the tool returns a list, but no further behavioral details (e.g., pagination, ordering). No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise, using a clean Args/Returns structure. Every sentence adds value, with no redundancy or filler.
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 tool (2 optional parameters, output schema exists), the description covers the essentials. It lacks explicit mention of default behavior when no filter is provided (likely lists all), but this is implied. The return format is not detailed, but the output schema handles that.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but the description provides meaningful parameter details: 'filter_type' options are enumerated ('account_reference', 'service_reference', 'team_reference') and 'limit' is explained as 'Max results to return'. This adds significant context beyond the schema types.
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 states 'List webhook subscriptions' which clearly indicates the action and resource. It is specific enough to distinguish from sibling tools like 'list_services' or 'list_teams', but does not explicitly differentiate from 'get_webhook_subscription' (a single-resource fetch vs list).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives (e.g., 'get_webhook_subscription' for a single subscription). The description does not mention scope, prerequisites, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the description's additional mention of package requirements adds marginal context. No contradiction; description aligns with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Description is somewhat lengthy with an Args section that largely repeats schema. Front-loaded with main action, but includes redundant information. Could be more concise.
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?
Output schema exists, so return value explanation is not required. Covers basic purpose and feature availability but does not fully detail the query_model structure or its properties beyond schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Description minimally explains parameters: incident_id is restated, query_model vaguely described as 'including date range and additional details'. Schema provides description for 'since' but incident_id lacks schema description. With 0% schema coverage in description, it fails to significantly compensate.
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 'Get Outlier Incident information for a given Incident on its Service', providing specific verb, resource, and context. Distinguishes from sibling tools which are largely other get/list tools for different entities.
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?
Explains that outlier incidents deviate from expected patterns for the same Service and notes feature availability (Event Intelligence package or Digital Operations plan). Provides context for when to use but lacks explicit when-not-to-use or alternative tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readonly and idempotent, so the bar is lower. The description adds behavioral context beyond annotations, such as the resolution of service_ids to escalation policies and the default behavior of 'earliest' being True.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a structured docstring with Args and Returns sections, concise but covering all parameters. It could be slightly tighter, but it's well-organized.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With 9 parameters, an output schema, and annotations, the description covers the essential context. It explains parameter behavior and return type, though pagination or limit behavior could be more explicit.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It lists all parameters with brief explanations, adding meaning beyond the schema schema itself, especially for service_ids which includes resolution logic.
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 lists on-call schedules with optional filtering, using a specific verb and resource. However, it does not explicitly distinguish from sibling tools like list_escalation_policies or list_schedules, missing some differentiation.
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 like list_escalation_policies or list_schedules. The description only says 'with optional filtering,' which implies usage but does not state exclusions or conditions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds no further behavioral context beyond the basic operation, so it meets a baseline but does not exceed.
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 reasonably concise but includes a redundant Args/Returns format that echoes the schema. Each sentence is functional, but could be tightened without loss of clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has an output schema (StatusPageImpact objects), and the description mentions the return type. Given the low complexity and no additional context needed, it is adequate, though a brief explanation of what an impact is would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% for top-level parameters. The description adds definitions for status_page_id (ID of the Status Page) and query_model (optional filtering parameters), which compensates for the schema gap. However, query_model remains vague.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists impacts for a status page by ID. The verb 'list' and resource 'Impacts' are specific, and it distinguishes from sibling list tools like list_status_pages.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives like list_status_page_post_updates. No when-not-to-use or alternative recommendations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, fully covering the safety profile. The description adds minimal behavioral context beyond stating it returns a list, which is already implied.
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: one sentence for purpose, followed by a clear Args/Returns block. Every sentence adds value with no 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?
Given the presence of an output schema and thorough annotations, the description covers the essentials. However, it omits details about the query_model parameter, which is crucial for filtering. This leaves a gap in completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. The description mentions the two required IDs with brief context ('The ID of the Status Page' etc.), but fails to describe the 'query_model' parameter beyond calling it 'Optional filtering parameters'. This is insufficient for an agent to construct correct inputs.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'List' and the resource 'Post Updates' for a Status Page, explicitly specifying the required identifiers (status_page_id and post_id). This distinctively separates it from sibling tools like 'get_status_page_post' and other list tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives. The description implies usage via required parameters but does not mention contraindications or comparisons with sibling tools. It is adequate but not helpful for discriminating between similar list tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so safety is clear. The description adds that it returns a list, which is expected. No additional behavioral traits disclosed, but with annotations present, 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?
Well-structured with Args and Returns sections. Short, front-loaded purpose, every sentence adds value. No unnecessary verbiage.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Description explains status_page_id as 'The ID of the Status Page' and query_model as 'Optional filtering parameters'. Schema coverage is 0% for top-level parameters, but subfields have descriptions. The description adds basic meaning but does not fully compensate for the lack of schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clear verb 'List' and specific resource 'Severities for a Status Page' by ID. Distinguishes from sibling tools like list_status_page_statuses and list_status_pages, as it targets a different sub-resource.
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?
States when to use (list severities for a given status page) but lacks explicit guidance on when not to use or alternatives. No comparison to similar list functions, though the name and description imply the correct context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, which cover the key behavioral traits. The description adds little beyond stating the action, so no contradiction and adequate but not enhanced transparency.

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint, idempotentHint, and destructiveHint. The description adds no behavioral context beyond 'Returns: List of users', which is obvious from the tool name. No contradiction.
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?
Extremely concise with clear sections for Args and Returns. Every sentence earns its place, and the description is front-loaded with the core purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity (one required parameter, read-only operation) and presence of an output schema, the description is mostly complete. Minor omission: no mention of pagination or ordering of results, but acceptable for a straightforward list 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?
The single parameter 'schedule_id' lacks description in the schema (0% coverage). The tool description adds 'The ID of the schedule', providing necessary context that the schema title 'Schedule Id' does not fully convey.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'List users in a schedule' with a specific verb ('List') and resource ('users in a schedule'). It distinguishes from sibling tools like 'list_users' (all users) and 'list_oncalls' (who is on call).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives such as 'list_oncalls' or 'list_users'. The description only restates the function without context or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the description adds no new behavioral context. It does not mention pagination or rate limits, but given annotations, a 3 is appropriate.
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—6 lines total—with purpose first, then parameters, then return. Every sentence provides value; 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 the annotations cover safety, and an output schema exists, the description adequately covers what the tool does. It could mention the return structure explicitly, but the output schema compensates. Overall sufficient for a list operation.
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?
Despite 0% schema description coverage, the description explains all three parameters: schedule_id as 'The ID of the v3 schedule', since/until as ISO 8601 time range with required. This adds meaningful context beyond schema, though examples would improve it further.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists overrides for a v3 schedule within a time range, specifying the resource and action. It distinguishes from siblings like get_schedule_v3_override (single override) by including 'list' and time range.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives (e.g., get_schedule_v3_override for a single override). Lacks when-not or comparative context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds no extra behavioral context beyond that, but does not contradict the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?

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 retrieval tool with one parameter and an output schema, the description is complete. It covers the action, required parameter, and what is returned. Annotations handle safety. The sibling context reinforces that this is a standard pattern.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It explains team_id as 'The ID or name of the team to retrieve', adding semantic value by specifying it can be either ID or name. This clearly defines the parameter's meaning and usage.

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., get_extension_schema). The context is implied but not stated, leaving the agent without clear decision 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?
Annotations already indicate readOnlyHint=true and idempotentHint=true, so the description need not cover safety. It adds that the tool returns a list of StatusPageStatus objects and mentions optional filtering via query_model. However, it does not disclose pagination behavior or error handling, which are moderate omissions.
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 concise with clear sections (Args, Returns) and front-loads the main purpose. It avoids unnecessary words but could be slightly more efficient by integrating parameter details inline.
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 simplicity (list with optional filter), annotations provide safety, and an output schema likely describes return objects. The description covers the essential inputs and output shape. It lacks pagination details, but for a straightforward list tool, it is sufficiently complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% at the top level, but the nested $defs provide descriptions for limit and post_type. The tool description adds minimal value: 'The ID of the Status Page' for status_page_id and 'Optional filtering parameters' for query_model.

The description does not contradict the annotations (readOnlyHint, idempotentHint, destructiveHint) and adds parameter details. However, it does not disclose additional behavioral traits beyond what annotations already imply, such as potential pagination or rate limits.
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 highly concise: one sentence for the purpose, a bulleted arg list, and a returns line. No unnecessary words, and the main action 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 presence of an output schema (not shown but mentioned), the description adequately covers the tool's operation. It explains the return as a list of services, which is sufficient for a simple query 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?
The description adds clear meaning to all three parameters: 'query' filters by name, 'teams_ids' filters by team IDs, and 'limit' caps results. This compensates for the 0% schema description coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'List all services' with optional filtering parameters, making the tool's purpose explicit. The name 'list_services' directly reflects the action, and it is distinguished from sibling tools like 'list_business_services' or 'list_teams'.
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 explains what the tool does and lists parameters, but provides no guidance on when to use this tool over alternatives like 'get_service' for a single service or other list tools. It lacks explicit usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false. Description adds pagination default and return type, but no additional behavioral traits beyond what annotations already provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Concise, front-loaded with purpose, then args, then returns. Every sentence is necessary and well-structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple nature of the tool (list with filters), annotations covering safety, and an output schema present, the description is complete with no missing aspects.
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 description coverage is 0%, so description fully compensates by explaining each parameter (query filters by name, teams_ids filters by team, limit for pagination) with clear semantics.
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?
Clearly states verb 'List' and resource 'users', with optional filtering options. However, it does not explicitly differentiate from sibling list tools like list_team_members, which might also list users filtered by team.
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?
Implies usage (list users with optional filters) but lacks explicit when-to-use or when-not-to-use guidance, nor mentions alternatives among sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint. The description adds 'Get' and return value indication but does not provide additional behavioral context such as authentication needs or rate limits. Minimal extra value beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise, with the primary action stated in the first line. Every sentence serves a purpose: the action, parameter explanation, and return indication. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (1 parameter, no nested objects, output schema present), the description is complete. It covers what the tool does, what input it expects, and what it returns. The output schema handles return details.
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 only parameter 'schema_id' has a clear description: 'The ID of the extension schema to retrieve.' This adds meaning beyond the schema's title 'Schema Id', compensating for the 0% schema description coverage. For a simple ID parameter, this is sufficient.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states 'Get a specific extension schema by ID' with a specific verb and resource. This distinguishes it from sibling tool 'list_extension_schemas' which lists all schemas.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool vs alternatives. The name and description imply it's for a single schema by ID, but there's no mention of when not to use it or comparisons with related tools like list_extension_schemas.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true, so the description adds limited behavioral context. It mentions 'oncall hours are computed authoritatively, accounting for schedule overlaps,' which provides extra confidence but does not disclose any new behavioral traits beyond what annotations convey.
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 well-structured with a clear purpose statement, a brief paragraph on functionality, and a bullet-point Args list. It is appropriately sized given the parameter count, though the 'Returns' line is slightly redundant with the output schema present. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 8 parameters (2 required), 0% schema description coverage, and presence of output schema, the description covers all parameters with types and acceptable values, explains the return type, and provides operational context (authoritative computation). This is complete for effective agent use.
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?
The input schema has 0% description coverage, but the description provides a detailed Args section explaining each parameter, including value formats (ISO8601, 'asc'/'desc'). This fully compensates for the missing schema descriptions and adds meaningful guidance for correct invocation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool gets responder metrics aggregated by team from PagerDuty Analytics, listing specific metrics (oncall seconds, interruption counts, engaged time, incident counts). This distinguishes it from sibling tools like get_responder_load_metrics and get_incident_metrics_* by focusing on responder-level analytics.
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 defines the tool's purpose and parameters but does not explicitly state when to use it versus alternatives. It implies usage for responder metrics but lacks guidance on exclusions or when other analytics tools are more appropriate. The context of date range and filters is clear, but no alternatives are mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds no behavioral traits beyond stating it returns a list. It does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is succinct, front-loads the main purpose, and uses a clean Args/Returns structure. Every sentence adds value with no 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?
Despite having an output schema, the description lacks details on pagination behavior, default limit, or query matching rules. For a list tool with 5 optional parameters, more context on edge cases would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It explains each parameter (e.g., 'query: Filter by name', 'limit: Max results to return'). However, 'include' is described vaguely as 'e.g. services, teams' without specifying exact allowable values.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states 'List escalation policies with optional filtering', which clearly identifies the verb (list) and resource (escalation policies). It distinguishes from the sibling 'get_escalation_policy' by implying a multi-result operation.
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 mentions optional filtering parameters, indicating when to use it (when multiple policies are needed). However, it does not explicitly state when not to use it or name alternatives like 'get_escalation_policy' for a single policy.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5

Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, covering safety. The description adds context about the nature of custom shifts and the required time range. No contradictions.
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 clear definition followed by parameter list. Every sentence adds value, no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given an output schema exists, the description explains it returns a 'List of custom shifts in the specified time range.' All necessary information is present for a list operation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description explains all three required parameters: schedule_id (ID of v3 schedule), since and until (ISO 8601, required). This adds meaning beyond the schema which only provides type string and title.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'List custom shifts for a v3 schedule within a time range' and defines custom shifts as 'ad-hoc one-off shifts outside of rotation events.' This distinguishes it from sibling tools like 'get_schedule_v3_custom_shift' (singular) and 'list_schedule_v3_overrides' (overrides vs custom shifts).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for listing custom shifts but does not explicitly state when to use this tool vs alternatives like 'list_schedule_v3_overrides' or 'list_schedule_v3_rotation_events.' No exclusions or when-not-to-use guidance is provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds the return type ('List of events defining the on-call coverage windows and member assignments'), which provides useful context beyond the annotations. However, no additional behavioral traits are disclosed.
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 brief and well-structured, with a one-line purpose, followed by Args and Returns sections. No extraneous information; every sentence is necessary and front-loaded.
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?
The tool has two simple required parameters, a clear purpose, and an output schema (implied). The description explains the return value adequately: 'List of events defining the on-call coverage windows and member assignments'. All necessary context is provided.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description elaborates on both parameters: 'schedule_id: The ID of the v3 schedule' and 'rotation_id: The ID of the rotation'. This adds meaning beyond the schema titles, which are just 'Rotation Id' and 'Schedule Id'.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states 'List all events for a rotation in a v3 schedule', using a specific verb and resource. It clearly distinguishes from sibling tools like 'list_schedule_v3_rotations' and 'get_schedule_v3_rotation_event'.
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 list events for a rotation). While it does not explicitly state when not to use it, the purpose is unambiguous and sibling names provide differentiation, making usage context 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?
Annotations already signal read-only, idempotent, non-destructive behavior. The description adds context about aggregation via PagerDuty Analytics, but doesn't reveal additional behavioral traits beyond what annotations provide. It is consistent and adds marginal value.
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 key information front-loaded. It uses a clear structure: purpose, metrics, usage guidance, then parameter and return details. No redundant sentences.
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?
All 8 parameters are described, required parameters highlighted, output model referenced (with output schema present), and alternative tools mentioned. No gaps for an 8-parameter tool with output schema.
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?
The input schema has 0% description coverage, but the text fully describes each parameter with examples and semantics (e.g., 'created_at_start: ISO8601 DateTime. Incidents created before this are omitted'). This adds substantial meaning beyond the schema alone.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb ('Get'), the resource ('incident metrics per service'), and the specific metrics (MTTA, MTTR, etc.). It also distinguishes this tool from list_incidents by highlighting pre-aggregation, making its purpose unambiguous.
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?
Explicit guidance is given: 'Use this instead of list_incidents when you need service health metrics — data is pre-aggregated.' This clarifies the appropriate context. A minor improvement would be to explicitly state when not to use it (e.g., for raw incident data), but the guidance is already effective.
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?
Annotations already indicate read-only, idempotent, and non-destructive behavior. The description adds behavioral context beyond annotations by detailing pagination (after, before, limit) and the option to include total count, which are important for understanding how the tool behaves.
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 clear structure: a one-sentence purpose followed by an Args list and a Returns line. It is front-loaded and avoids unnecessary words, effectively communicating all necessary information.
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 that there are 5 parameters, no enums, an output schema exists, and annotations cover safety, the description provides complete guidance. It explains filtering and pagination, which are the main complexities, and the output schema handles return value details.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must add meaning. It provides clear explanations for all 5 parameters (service_ids, limit, after, before, total), including their purpose and defaults. This goes well beyond the bare schema, though it could be more precise about cursor formats.
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 starts with 'List all alert grouping settings with optional filtering,' clearly stating the verb (list) and resource (alert grouping settings). It distinguishes itself from sibling tools like 'get_alert_from_incident' or 'list_incidents' by specifying the exact resource being listed.
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 explains parameters like service_ids for filtering, which gives context on when to use the tool (e.g., to list settings for specific services). However, it does not explicitly state when not to use this tool or provide alternatives, leaving this dimension minimally adequate.
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?
Annotations already declare readOnly and idempotent. Description adds critical behavior: merge logic, per-source status on failure, enrich behavior, and an instruction to never claim a schedule type unsupported. No contradiction.
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?
Well-structured with overview, args, and returns sections. Slightly verbose but still clear and informative. Could be trimmed but earns its place.
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?
Completely covers the tool's behavior: merge of two systems, failure handling, enrich option details, and return structure (degraded flag). Suitable 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.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has descriptions for all sub-parameters (high coverage), so baseline 3. Description adds extra: query_model filters differently per schedule type, enrich fills names for v3 only and is bounded. This adds meaningful context beyond 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?
Description clearly states it lists all schedules across both v2 and v3 systems, with no other list tool available. It distinguishes from siblings like get_schedule (single) and list_schedule_* (specific aspects).
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 it's the complete authoritative list with no alternative, but does not explicitly contrast with get_schedule for single schedule retrieval. Provides usage caution about error handling and enrich option.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds behavioral details such as the requirement that both IDs must be 'known, non-empty PagerDuty IDs', which is not captured by annotations. This provides additional context beyond the structured data.
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: a one-line purpose, a note on ID requirements, usage guidance with a sibling reference, and an Args section. Every sentence adds value, and the critical information is front-loaded. No redundancy or waste.
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 retrieval tool with two required string parameters, no nested objects, and an existing output schema, the description is fully complete. It covers purpose, ID format, usage alternatives, and return value ('Alert details'). The output schema handles detailed return structure, so no further explanation needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% (no parameter descriptions in the schema), so the description must compensate. It includes an 'Args' section explaining incident_id and alert_id as 'The ID of the incident' and 'The ID of the alert', plus the note that IDs must be non-empty PagerDuty IDs. This adds meaningful semantic context beyond the bare property names, though deeper format details could improve it.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Get a specific alert from an incident' using a specific verb and resource. It distinguishes itself from the sibling tool 'list_alerts_from_incident' by noting that this tool retrieves a single alert given both IDs, while the list tool is for discovery.
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 explicitly tells when to use this tool (when both IDs are known) and when not to (if alert ID is unknown, use list_alerts_from_incident). It warns against using empty or placeholder alert_id, providing clear usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true, so the safety profile is clear. The description adds useful behavioral context about the aggregated nature and percentile fields, but does not cover rate limits or auth details.
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 well-structured with sections but slightly verbose. The parameter list is helpful, though it could be more concise. Overall, every part earns its place.
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 complexity (8 params, 2 required), the description covers purpose, usage guidelines, parameter semantics, return type, and differentiation. Output schema exists, so return value details are not needed. Complete.
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 description coverage is 0%, but the description provides detailed explanations for all 8 parameters, including meaning and expected formats, fully 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.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool gets full-period aggregated metrics, with specific verb and resource. It differentiates from sibling tools by highlighting the availability of percentile distributions only from this endpoint.
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?
Explicitly states when to use this tool vs alternatives: 'These percentile fields are ONLY available from this endpoint — not from the per-team or per-service grouped endpoints.'
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 elaborates on behavior beyond annotations: it works for both schedule types, resolves automatically, and the kind hint can be wrong or omitted without error. This aligns with readOnlyHint and idempotentHint annotations, adding valuable context.
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, well-structured, and front-loads the core purpose. Every sentence adds value, with no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema, the description sufficiently covers the tool's input, behavior, and return type. It is complete for a get-single-entity operation with two parameters.
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?
With 0% schema description coverage, the description fully documents both parameters: schedule_id is clearly the ID to retrieve, and kind is an optional hint that resolves correctly even if wrong. This adds significant meaning over the bare 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 ('Get a single schedule by ID') and the resource ('schedule'). It explicitly mentions compatibility with both layer-based and shift-based schedules, distinguishing it from sibling tools like list_schedules or get_schedule_v3_custom_shift.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explains that normally no kind specification is needed, and that the kind parameter is an optional hint. It provides clear guidance on usage but does not explicitly mention when not to use this tool or alternatives like list_schedules.
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?
Annotations already indicate readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds details about return type and parameter behavior without contradiction.
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?
