getDocumentParts

Read-only

Retrieves a list of Document Parts from a Polarion document, supporting pagination, field selection, and revision history. Use it to browse or batch-collect parts instead of fetching a single part by ID.

Instructions

Returns a list of Document Parts. Cardinality: targets the full collection or a batch. For a single item by ID, use getDocumentPart 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.
spaceIdYesThe Document Space ID (a folder-like grouping of documents/pages within a project). Use `_default` (no quotes) to address the project's default space.
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.
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.
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.
documentNameYesThe Document name.
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

  7. First observedv1.0.0

TDQS

A4.3/5.0
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 useful cardinality context (full collection or batch), but it does not discuss pagination behavior, payload implications, or other operational details beyond what annotations and schema 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?

Two short sentences, with the core purpose and cardinality front-loaded and the alternative sibling named immediately afterward. There is no redundant or filler text.

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 description is complete for a list tool whose schema is fully documented and which has an output schema. It clearly states the operation, scope, and singular alternative, leaving pagination and field selection to the well-described schema.

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 schema fully documents the ten parameters, including pagination, sparse fields, includes, and response format. The description adds no parameter-level semantics, which is acceptable given the schema's richness; baseline 3 applies.

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 Document Parts.' It also explicitly distinguishes the collection/batch scope from the singular sibling `getDocumentPart`, so an agent can select it 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 Guidelines5/5

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

It gives clear usage guidance: this tool targets the full collection or a batch, while a single item by ID should use `getDocumentPart` instead. The when-to-use and when-not-to-use conditions are explicit.

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