getProjectTestParameterDefinition

Read-only

Retrieves a single Test Parameter Definition by ID within a Polarion project, returning its details for targeted test configuration lookup.

Instructions

Returns the specified Test Parameter Definition for the specified Project. Cardinality: targets a single item by ID. For the full collection or a batch, use getProjectTestParameterDefinitions 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.
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.
testParamIdYesThe Test Parameter.
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

  7. First observedv1.0.0

TDQS

A3.8/5.0
Behavior3/5

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

readOnlyHint=true and openWorldHint=true already establish the safety profile, so the description's main contribution is the cardinality statement ("targets a single item by ID"). It adds nothing about behavior on a missing ID, whether the definition is resolved within the project scope only, or the cost of the call; with annotations and an output schema carrying that weight, 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?

Three short sentences with zero padding: identity first, then cardinality, then the routing hint. Every clause carries information the agent needs.

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 a full output schema, complete annotation coverage and a fully described 5-parameter schema, the description only needs to establish identity and cardinality, which it does. The only shortfall is that it never clarifies its relationship to the test-run and work-item definition variants.

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 projectId, testParamId, fields, include and response_format are all documented in the schema itself; the description adds no further parameter guidance. Baseline 3 applies — the description neither compensates for nor undermines the 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?

States a specific verb and resource ("Returns the specified Test Parameter Definition for the specified Project") plus its cardinality, which separates it cleanly from the plural sibling. It does not distinguish itself from the other single-item definition getters (getTestRunTestParameterDefinition, getWorkItemTestParameterDefinition), leaving the agent to infer the scope difference from the name alone.

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 names the alternative `getProjectTestParameterDefinitions` and the condition that selects it ("For the full collection or a batch"). It gives no exclusion guidance against the test-run or work-item definition getters, which is a real ambiguity in this sibling set.

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