getTestRecordTestParameters

Read-only

Retrieves all Test Parameters for a specified Test Record in a Polarion project, supporting batch retrieval; use the single-item tool when you need one parameter by ID.

Instructions

Returns a list of Test Parameters for the specified Test Record. Cardinality: targets the full collection or a batch. For a single item by ID, use getTestRecordTestParameter instead.

Input Schema

NameRequiredDescriptionDefault
fieldsNoSparse fieldset selector: an object keyed by resource type (e.g. `workitems`) whose value is a comma-separated list of attribute names to return (e.g. `id,title,status`), reducing payload size. Omit to return the default field set.
includeNoComma-separated list of related resource types to embed in the response (e.g. `author,attachments`) so they don't require a separate follow-up call. Omit to return only the primary resource.
revisionNoA specific repository revision (e.g. `1234`) to read the resource as it existed at that revision instead of the current HEAD. Omit to use the latest revision.
iterationYesThe iteration number identifying which repeated occurrence of this item is being addressed (e.g. which run of a test parameter).
max_itemsNoCollect up to this many results across pages (maximum 1000). Omit to fetch only the requested page, as before.
projectIdYesThe Polarion project ID (its URL segment, e.g. `myproject`), case-sensitive. Required to scope the request to one project. If the ID is unknown, ask the user; getProjects lists IDs only with global read access.
testRunIdYesThe Test Run's ID within its project.
page_size_NoMaximum number of items to return in this page (e.g. `100`). Use together with `page[number]` to paginate through a large result set.
testCaseIdYesThe Test Case's ID being referenced.
page_number_No1-based page number to fetch when the result set is paginated (e.g. `2` for the second page). Combine with `page[size]`; omit to fetch the first page.
response_formatNoResponse detail level. concise removes redundant HTML and JSON:API metadata and may use a small default fieldset on large lists; detailed preserves the complete response. Defaults to detailed.detailed
testCaseProjectIdYesThe project ID that owns the referenced Test Case — may differ from the project in the request path when the test case is shared from another project.

  7. First observedv1.0.0

TDQS

A4.4/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds useful behavioral context about cardinality (full collection or batch) and the existence of a singular counterpart, but it does not add details like pagination interaction or authentication requirements beyond what the schema and annotations provide.

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

Conciseness5/5

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

The description is two tightly written sentences plus a cardinality note, with the primary purpose front-loaded and the alternative routing immediately after. No sentence is wasted.

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

Completeness4/5

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

Given an output schema, complete schema descriptions, and annotations, the description needn't explain return values or safety. It adequately covers purpose and sibling routing, though it does not mention that the operation is read-only or that pagination parameters are available, minor omissions given the rich structured data.

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 all 12 parameters are already documented in the input schema. The description adds no parameter-specific syntax, format, or default information beyond the schema, which is acceptable at baseline 3 for a high-coverage 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 uses a specific verb and resource ('Returns a list of Test Parameters for the specified Test Record') and immediately distinguishes the tool from its singular sibling. An agent can identify the operation and its collection scope without opening the schema.

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?

It explicitly states when to use this tool ('targets the full collection or a batch') and names the exact alternative for the single-item case ('For a single item by ID, use `getTestRecordTestParameter` instead'). The routing condition is unambiguous.

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