getTestRunTestParameters

Read-only

Retrieve all Test Parameters for a specified Polarion Test Run to inspect or process its parameter collection. Use it when you need the full list rather than a single parameter by ID.

Instructions

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

Input Schema

Name	Required	Description	Default
`fields`	No	Sparse 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.
`include`	No	Comma-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.
`revision`	No	A 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.
`max_items`	No	Collect up to this many results across pages (maximum 1000). Omit to fetch only the requested page, as before.
`projectId`	Yes	The 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.
`testRunId`	Yes	The Test Run's ID within its project.
`page_size_`	No	Maximum number of items to return in this page (e.g. `100`). Use together with `page[number]` to paginate through a large result set.
`page_number_`	No	1-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_format`	No	Response 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

Output Schema

Name	Required	Description
`data`	No
`meta`	No
`links`	No
`included`	No	Related entities might be returned, see <a href="https://docs.sw.siemens.com/en-US/doc/230235217/PL20250606201928474.polarion_help_sc.xid2134849/xid2134871" target="_blank">REST API User Guide</a>.

TDQS

A3.9/5.0

Behavior3/5

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 a cardinality note, but 'targets the full collection or a batch' is vague and 'batch' is undefined; it says nothing about how this tool paginates even though it exposes page_size_, page_number_ and max_items.

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, zero padding, with the purpose front-loaded ahead of the sibling redirect. The only soft spot is the jargon phrase 'Cardinality: targets the full collection or a batch', which is compact but under-explained.

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 list endpoint with nine parameters, an output schema and full schema coverage, the description supplies what structured fields cannot: scope and sibling routing. Behaviour-specific details like pagination semantics are left to the schema, which is reasonable given the 100% coverage.

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 nine parameters (fields, include, revision, max_items, response_format, pagination) are already documented in the schema, making 3 the baseline. The description adds no meaning beyond that — for example, it does not explain how max_items interacts with page_size_.

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 a specific verb and resource — 'Returns a list of Test Parameters for the specified Test Run' — and explicitly distinguishes itself from the singular sibling getTestRunTestParameter. An agent can select this over that sibling without opening either schema.

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?

It names the alternative (`getTestRunTestParameter`) and the condition that selects it (a single item by ID), which is the key routing decision here. It gives no guidance on the other alternatives the 9 parameters imply, such as when to page versus use max_items, but the core this-vs-sibling choice is resolved.

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