一般的なエラーのシナリオは次のとおりです。

無効なリソース ID (例: user_id、team_id、service_id)
必要なパラメータが不足しています
無効なパラメータ値
APIリクエストの失敗
応答処理エラー

パラメータ検証

すべてのIDパラメータは有効なPagerDutyリソースIDである必要があります
日付パラメータは有効なISO8601タイムスタンプである必要があります
リストパラメータ（例： statuses 、 team_ids ）には有効な値が含まれている必要があります
リストパラメータ内の無効な値は無視されます
必須パラメータはNoneまたは空の文字列にすることはできません
list_incidentsのstatusesの場合、有効な値はtriggered 、 acknowledged 、 resolvedのみです。
インシデントのurgencyについては、 highとlowのみが有効値です
limitパラメータはリスト操作によって返される結果の数を制限するために使用できます。

レート制限とページネーション

サーバーはPagerDutyのレート制限を尊重します
サーバーが自動的にページ区切りを処理します
limitパラメータはリスト操作によって返される結果の数を制御するために使用できます。
制限が指定されていない場合、サーバーはデフォルトで最大{pagerduty_mcp_server.utils.RESPONSE_LIMIT}件の結果を返します。

使用例

from pagerduty_mcp_server import incidents
from pagerduty_mcp_server.utils import RESPONSE_LIMIT

# List all incidents (including resolved) for the current user's teams
incidents_list = incidents.list_incidents()

# List only active incidents
active_incidents = incidents.list_incidents(statuses=['triggered', 'acknowledged'])

# List incidents for specific services
service_incidents = incidents.list_incidents(service_ids=['SERVICE-1', 'SERVICE-2'])

# List incidents for specific teams
team_incidents = incidents.list_incidents(team_ids=['TEAM-1', 'TEAM-2'])

# List incidents within a date range
date_range_incidents = incidents.list_incidents(
    since='2024-03-01T00:00:00Z',
    until='2024-03-14T23:59:59Z'
)

# List incidents with a limit on the number of results
limited_incidents = incidents.list_incidents(limit=10)

# List incidents with the default limit
default_limit_incidents = incidents.list_incidents(limit=RESPONSE_LIMIT)

ユーザーコンテキスト

多くの関数はcurrent_user_contextパラメータ（デフォルトはTrue ）を受け付けます。このパラメータは、このコンテキストに基づいて結果を自動的にフィルタリングします。current_user_context がTrueの場合、自動フィルタリングと競合するため、特定のフィルタパラメータは使用current_user_contextません。

すべてのリソースタイプの場合:
- user_ids``current_user_context=Trueでは使用できません
インシデントの場合:
- team_idsとservice_ids``current_user_context=Trueでは使用できません
サービスの場合:
- team_ids``current_user_context=Trueでは使用できません
エスカレーションポリシーの場合:
- team_ids``current_user_context=Trueでは使用できません
オンコールの場合:
- user_ids``current_user_context=Trueでは使用できません
- schedule_ids特定のスケジュールでフィルタリングするために引き続き使用できます。
- クエリは、現在のユーザーのチームに関連付けられているすべてのエスカレーションポリシーのオンコールを表示します。
- これは、「現在私のチームでオンコールになっているのは誰ですか?」などの質問に答えるのに役立ちます。
- 現在のユーザーのIDはフィルターとして使用されないため、オンコール中のチームメンバー全員が表示されます。

ParametersJSON Schema

Name	Required	Description
No output parameters

TDQS

B3.3/5.0

Behavior2/5

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

With no annotations, the description must disclose behavioral traits. It mentions 'signals that someone is actively working' but omits details like status changes, permissions, or reversibility.

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

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no wasted words. Front-loaded with the action and immediate context.

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 and simple parameters, the description lacks context on usage nuance versus siblings, e.g., when to acknowledge vs resolve.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema sufficiently describes parameters. The description adds no extra parameter meaning, resulting in baseline score.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

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

The description uses a specific verb 'acknowledge' and resource 'incident', clearly distinguishing it from sibling tools like 'resolve_incident' or 'add_incident_note'.

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, nor any preconditions or exclusions. It only states the basic action.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

add_incident_noteA

Add a note to a PagerDuty incident. Notes are used to record additional context, investigation progress, or resolution details.

ParametersJSON Schema

Name	Required	Description	Default
`incident_id`	Yes	The ID of the incident to add a note to (required).
`content`	Yes	The text content of the note (required).

Output Schema

ParametersJSON Schema

Name	Required	Description
No output parameters

TDQS

A3.6/5.0

Behavior2/5

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

No annotations are provided, so the description must convey behavioral traits. It only describes the action as adding a note, without disclosing limits, append-only behavior, or whether notes can be edited/deleted.

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

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loading the main action and providing context in the second sentence with no redundant 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 that an output schema exists and the tool has low complexity (2 required params), the description adequately covers the purpose and parameter usage, though it lacks behavioral details. A score of 4 reflects it is mostly complete for an agent to use correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description does not add any additional context beyond what the schema provides for the parameters 'incident_id' and 'content'.

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 adds a note to an incident and explains the purpose of notes, distinguishing it from sibling tools like acknowledge or resolve.

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 adding context or progress, but does not explicitly state when to use this tool versus alternatives or mention prerequisites like incident ID validity.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

build_user_contextA

Validate and build the current user's context into a dictionary with the following format: { "user_id": str, "team_ids": List[str], "service_ids": List[str], "escalation_policy_ids": List[str] } The MCP server tools use this user context to filter the following resources: - Escalation policies - Incidents - Oncalls - Services - Users

A3.9/5.0

Behavior3/5

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

No annotations provided, description fully responsible. Discloses output format and filtered resources, but lacks info on side effects, authentication needs, or error cases.

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

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single paragraph with key information front-loaded. Could be streamlined slightly but no wasted sentences.

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?

No parameters, output schema exists. Description explains output format and usage context adequately, though missing prerequisites like authentication state.

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 in schema, baseline 4. Description adds meaning by explaining output structure and purpose of the context.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

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

Description clearly states the tool validates and builds user context dictionary with explicit format. Distinguishes from siblings which are resource-specific 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?

Implied usage for filtering resources before other tool calls, but no explicit when-to-use or alternatives mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_escalation_policiesA

Get PagerDuty escalation policies by filters or get details for a specific policy ID.

ParametersJSON Schema

Name	Required	Description
`policy_id`	No	The escalation policy ID to retrieve (optional, cannot be used with any other filters).
`current_user_context`	No	Use current user's ID/team IDs context (default: True). Not used if `policy_id` is provided.
`query`	No	Policies whose names contain the search query (optional). Not used if `policy_id` is provided.
`user_ids`	No	Policies that include these user IDs (optional, excludes current_user_context). Not used if `policy_id` is provided.
`team_ids`	No	Policies assigned to these team IDs (optional, excludes current_user_context). Not used if `policy_id` is provided.
`limit`	No	Limit the number of results (optional). Not used if `policy_id` is provided.
`include`	No	List of fields to include in the response. If specified, only these fields will be returned for each escalation policy

Output Schema

ParametersJSON Schema

Name	Required	Description
No output parameters

TDQS

A4/5.0

Behavior3/5

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

No annotations are provided, so the description must disclose behaviors. It only states the basic retrieval operation without mentioning rate limits, pagination, or auth requirements. The read-only nature is implied but not explicit.

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

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence that front-loads the action. No unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

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

Given the tool's moderate complexity (7 parameters with interdependencies), the description is minimal but sufficient combined with schema descriptions and output schema. It could mention pagination, but the limit parameter covers that.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All seven parameters have full schema descriptions (100% coverage), so the description adds no new parameter semantics. It summarizes the two modes but does not elaborate on parameters beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

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

The description clearly states the tool retrieves PagerDuty escalation policies with two modes: listing by filters or fetching details by ID. This distinguishes it from sibling tools focused on incidents, oncalls, etc.

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?

While the description implies usage for retrieving escalation policies, it does not explicitly state when to prefer this over other tools or provide exclusion criteria. However, the sibling tools are on different resources, so context is clear.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_incidentsB

Get PagerDuty incidents by filters or get details for a specific incident ID or number.

ParametersJSON Schema

Name	Required	Description
`incident_id`	No	The incident ID or number to retrieve (optional, cannot be used with any other filters).
`current_user_context`	No	Filter by current user's context (default: True). Not used if `incident_id` is provided.
`service_ids`	No	Filter by services (optional, excludes current_user_context). Not used if `incident_id` is provided.
`team_ids`	No	Filter by teams (optional, excludes current_user_context). Not used if `incident_id` is provided.
`statuses`	No	Filter by status (optional). Not used if `incident_id` is provided. Must be input as a list of strings, valid values are `["triggered", "acknowledged", "resolved"]`. Defaults to all statuses.
`urgencies`	No	Filter by urgency (optional). Not used if `incident_id` is provided. Must be input as a list of strings, valid values are `["high", "low"]`. Defaults to all urgencies. Account must have the urgencies ability to do this.
`since`	No	Start of query range in ISO8601 format (default range: 1 month, max range: 6 months). Not used if `incident_id` is provided.
`until`	No	End of query range in ISO8601 format (default range: 1 month, max range: 6 months). Not used if `incident_id` is provided.
`limit`	No	Max results (optional). Not used if `incident_id` is provided.
`include_past_incidents`	No	If True and `incident_id` is provided, includes similar past incidents in the response. Defaults to False. Cannot be used without `incident_id`.
`include_related_incidents`	No	If True and `incident_id` is provided, includes related incidents impacting other services/responders in the response. Defaults to False. Cannot be used without `incident_id`.

B3.1/5.0

Behavior2/5

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

With no annotations, the description must disclose behavioral traits, but it only states the function. It does not mention pagination, error handling, rate limits, or authentication requirements. Some behavior is implied by the input schema (e.g., mutual exclusivity of incident_id and filters), but the description itself is silent.

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

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence of 18 words, appropriately front-loaded with the verb and resource. It is concise, though it could benefit from slightly more detail to improve clarity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

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

Despite an output schema being present, the description fails to explain the tool's two usage modes (list vs. specific ID) clearly. With 13 parameters, more context about how parameters interact (e.g., mutual exclusivity) would be helpful. The description is too vague for a complex tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. The description adds little beyond saying 'filters' which the schema already details. It does not provide additional meaning or context for parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

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

The description clearly states the tool retrieves PagerDuty incidents, with two distinct modes: filtering by attributes or retrieving a specific incident by ID/number. This distinguishes it from sibling tools that perform actions on incidents (e.g., acknowledge_incident, resolve_incident).

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 to avoid using it or reference sibling tools, leaving the agent to infer usage from the name alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_oncallsA

List on-call entries for schedules, policies, or time ranges.

Behavior varies by time parameters:

Without since/until: Returns current on-calls Example: get_oncalls(schedule_ids=["SCHEDULE_123"])
With since/until: Returns all on-calls in range Example: get_oncalls(schedule_ids=["SCHEDULE_123"], since="2024-03-20T00:00:00Z", until="2024-03-27T00:00:00Z")

ParametersJSON Schema

Name	Required	Description
`current_user_context`	No	Use current user's team policies (default: True)
`schedule_ids`	No	Filter by schedules (optional)
`user_ids`	No	Filter by users (optional, excludes current_user_context)
`escalation_policy_ids`	No	Filter by policies (optional)
`since`	No	Start of query range in ISO8601 format (default: current datetime)
`until`	No	End of query range in ISO8601 format (default: current datetime, max range: 90 days in the future). Cannot be before `since`.
`limit`	No	Max results (optional)
`earliest`	No	Only earliest on-call per policy/level/user combo (optional)
`include`	No	List of fields to include in the response. If specified, only these fields will be returned for each on-call entry

Output Schema

ParametersJSON Schema

Name	Required	Description
No output parameters

TDQS

A4.3/5.0

Behavior4/5

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

Explains behavior variation with time parameters, includes examples, and mentions constraints like the 90-day max range for 'until'. No annotations provided, so description carries full burden and does so well, though permission requirements are absent.

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

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two paragraphs with clear first sentence and bulleted examples. Efficient but could be slightly more concise; still earns its sentences.

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?

Complex tool with 9 parameters. Covers main behavior variation well. The 'include' parameter is only briefly mentioned, and return values are not described (though output schema exists). Overall fairly complete for a read tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with detailed descriptions. The description adds value by explaining the behavioral difference of 'since' and 'until' and providing usage examples, which clarifies parameter semantics 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 'List on-call entries for schedules, policies, or time ranges' and distinguishes two modes based on time parameters. This specificity helps differentiate it from sibling tools like list_users_oncall.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit guidance on when to use without vs. with time parameters, including examples. However, it does not explicitly contrast with sibling tools or state when not to use this tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_schedulesB

Get PagerDuty schedules by filters or get details for a specific schedule ID.

ParametersJSON Schema

Name	Required	Description
`schedule_id`	No	The schedule ID to retrieve details for (optional, cannot be used with query or limit).
`query`	No	Filter schedules whose names contain the search query (optional). Not used if `schedule_id` is provided.
`limit`	No	Limit the number of results returned (optional). Not used if `schedule_id` is provided.
`since`	No	Start time for overrides/final schedule details (ISO8601, optional). Only used if `schedule_id` is provided. Defaults to 2 weeks before 'until' if 'until' is given.
`until`	No	End time for overrides/final schedule details (ISO8601, optional). Only used if `schedule_id` is provided. Defaults to 2 weeks after 'since' if 'since' is given.
`include`	No	List of fields to include in the response. If specified, only these fields will be returned for each schedule

B3.3/5.0

Behavior2/5

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

With no annotations, the description carries the full burden. It discloses no behavioral traits (e.g., pagination, rate limits, authentication). Only states basic functionality.

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

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, front-loaded with purpose, no wasted words. Efficiently communicates the core functionality.

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 6 parameters, 0 required, and an output schema, the description is adequate but lacks elaboration on use cases for optional parameters or response details. Not misleading but could be improved.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the description adds minimal new meaning. It restates the filter vs. ID distinction which is already captured in parameter descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

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

Description clearly states the action (get), resource (schedules), and two distinct modes (filter vs. specific ID). It distinguishes from sibling tools, none of which target schedules.

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 filters vs. schedule ID, or when to prefer this tool over alternatives. The description implies two use cases but does not provide decision criteria.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_servicesA

A3.5/5.0

Behavior2/5

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

The description only indicates a 'get' operation (read) but does not disclose any behavioral traits such as pagination behavior, default limits, rate limits, or effects on data. No annotations are provided, so the description carries the full burden. The presence of a 'limit' parameter implies pagination, but this is not mentioned in the description.

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

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence that covers both usage modes. It is front-loaded with the main action and resource, and every word serves a purpose. No redundancy or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

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

Given the tool has an output schema (not shown but present) and 100% schema parameter coverage, the description is minimally adequate. However, it lacks guidance on typical use cases, response format hints, or behavior when no filters are applied. For a simple read tool, it is acceptable but could be more informative.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the input schema already documents all parameters thoroughly. The description adds no additional meaning beyond the schema (e.g., it does not explain filter interactions or provide examples). Baseline 3 is appropriate as the schema does the heavy lifting.

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 that the tool retrieves PagerDuty services either by filters or by a specific service ID. The verb 'Get' and resource 'services' are explicit, and the two modes are distinct. Sibling tools like get_incidents or get_teams target different resources, so purpose differentiation is natural.

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. However, the resource name itself implies usage for services, and siblings are for other resources. No when-not-to-use or exclusion criteria are stated, which is a gap for a tool with multiple filter modes.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.8/5.0

Behavior3/5

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

No annotations are provided, so the description must convey behavioral traits. It implies a read-only operation but does not explicitly confirm safety, rate limits, or pagination. The presence of an output schema partially covers return format, but the description adds minimal behavioral context beyond the obvious.

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

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that conveys the essential purpose. It is concise and front-loaded, though it could be slightly more informative 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?

Given the schema covers all parameters and an output schema exists, the description is adequate for a simple read tool. However, it lacks explicit mention of its safe read-only nature and default behavior when no parameters are provided, leaving some contextual gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, with each parameter having a clear description. The tool description adds no further meaning beyond the schema, meeting the baseline expectation for parameter 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 tool retrieves PagerDuty teams, either by filters or by specific team ID. The verb 'Get' and resource 'teams' are specific, and the two usage modes are explicitly mentioned, distinguishing it from sibling tools focusing on other resources.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description indicates when to use filters versus a specific team ID, providing clear context for usage. However, it does not explicitly state when not to use the tool or mention alternatives, which would improve the score.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_usersB

Get PagerDuty users by filters or get details for a specific user ID.

ParametersJSON Schema

`user_id`	No	The user ID to retrieve (optional, cannot be used with any other filters).
`current_user_context`	No	Use current user's team IDs to filter (default: True). Not used if `user_id` is provided.
`team_ids`	No	Filter results to only users assigned to teams with the given IDs (optional, cannot be used with current_user_context). Not used if `user_id` is provided.
`query`	No	Filter users whose names contain the search query (optional). Not used if `user_id` is provided.
`limit`	No	Limit the number of results (optional). Not used if `user_id` is provided.
`include`	No	List of fields to include in the response. If specified, only these fields will be returned for each user

B3.2/5.0

Behavior2/5

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

With no annotations, the description must disclose behavioral traits, but it only states the basic operation. It does not mention rate limits, pagination, authentication, or default behavior (e.g., what happens without filters).

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

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is front-loaded and efficiently summarizes the tool's purpose with no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

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

Despite rich schema and output schema, the description is minimal. It does not explain default behavior (e.g., returning all users when no filters), pagination, or response details, leaving gaps for a new user.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. The description adds no additional meaning beyond the schema's parameter descriptions; it just says 'by filters'.

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 PagerDuty users either by filters or by a specific user ID, using a specific verb and resource. It distinguishes between two modes, which helps differentiate from siblings like list_users_oncall.

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_users_oncall). It lacks explicit context for selection among sibling tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_users_oncallC

List the users on call for a schedule during the specified time range.

ParametersJSON Schema

Name	Required	Description
`schedule_id`	Yes	The ID of the schedule to query
`since`	No	Start of query range in ISO8601 format
`until`	No	End of query range in ISO8601 format
`include`	No	List of fields to include in the response. If specified, only these fields will be returned for each user on call

C2.9/5.0

Behavior2/5

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

With no annotations provided, the description carries full burden for behavioral disclosure. It only states the action but omits details about side effects, safety (e.g., read-only nature), or behaviors when parameters are omitted (e.g., default range when since/until are null).

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

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence, front-loading the main action and resource. It is concise without being terse, though it could optionally add more context without becoming 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 the output schema exists, the description does not clarify behavior for missing time range parameters or mention pagination/limits. The tool seems simple, but important contextual details are absent for an agent to confidently invoke it.

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 covers all four parameters with descriptions (100% coverage). The description adds no additional meaning beyond the schema, so it meets the baseline expectation for parameter 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?

The description clearly states the verb 'list' and the resource 'users on call for a schedule during time range'. It is specific and unambiguous. However, it does not differentiate from the sibling tool 'get_oncalls', which may have overlapping functionality.

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 like 'get_oncalls'. There is no mention of prerequisites, limitations, or cases where this tool is inappropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

resolve_incidentA

ParametersJSON Schema

Name	Required	Description	Default
`incident_id`	Yes	The ID of the incident to resolve (required).
`include`	No	List of fields to include in the response. If specified, only these fields will be returned for the incident.

Output Schema

ParametersJSON Schema

Name	Required	Description
No output parameters

TDQS

A3.5/5.0

Behavior2/5

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

No annotations provided. The description only mentions marking as resolved and stopping escalations, but lacks detail on idempotency, reversibility, or permission requirements.

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

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with two clauses, no redundant information, and directly conveys the function.

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 action and effect, but lacks behavioral transparency and usage guidance. Given the simple nature and presence of output schema, it is minimally 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 coverage is 100% with clear parameter descriptions. The tool description adds no extra meaning beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

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

The description clearly states it resolves a PagerDuty incident and explains the effect (stops escalations). This differentiates it from siblings like acknowledge_incident.

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 resolving incidents but does not explicitly state when to use versus alternatives, nor does it mention prerequisites or context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS

A3.7/5.0

Scored 2026-06-04 03:00 across 12 tools

Disambiguation4/5

Most tools target distinct resources with clear actions. Slight overlap between get_oncalls and list_users_oncall, but descriptions clarify different use cases. Overall well-disambiguated.

Naming Consistency5/5

All tools use consistent snake_case with a verb_noun pattern (e.g., acknowledge_incident, get_services). No mixing of styles, making it predictable for an agent.

Tool Count5/5

12 tools covering incident actions, resource retrieval, and user context building is well-scoped for a PagerDuty incident response server. Neither too sparse nor unnecessarily large.

Completeness4/5

Incident lifecycle includes acknowledge, note, get, resolve, but missing create_incident or update_incident. Resource operations are read-only. For incident response context, surface is reasonably complete.
