postTestRunAttachments

Uploads one or more new files as attachments to a Polarion Test Run in a single multipart request and returns the created attachment IDs.

Instructions

Uploads one or more new files as attachments of a Test Run in a single multipart request: requestBody.resource.data holds one metadata entry (fileName, optional title) per file, and requestBody.files holds the base64-encoded file bytes at the same array index as each metadata entry. Returns the created attachment IDs. Use this to add files; to change an existing attachment use patchTestRunAttachment, and to list what is already attached use getTestRunAttachments. Effect: creates a new resource. Repeating this call may create additional resources; it is not guaranteed idempotent. Tip: set dry_run: true first to validate the arguments and preview the exact request without sending it to Polarion. The executor returns this preview as normal text, and as structured content when the tool declares an output schema.

Input Schema

NameRequiredDescriptionDefault
dry_runNoIf true, validates the request and returns the exact request that would be sent to Polarion — with the Authorization header redacted and any binary payload summarized by byte length — without actually sending it.
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.
requestBodyYesAttachment metadata and file data.

Output Schema

TDQS

A4.7/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false, but the description adds valuable context: the multipart layout, that repeating may create additional resources, and that dry_run previews the request without sending it. Some sentences restate annotation or output-schema facts, but the additional multipart and dry-run details make the behavior clear.

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 front-loaded with the core action and multipart structure, then routing alternatives and behavioral notes. It is somewhat long, and the closing note about structured content when an output schema is declared adds little for the caller, but the content is largely purposeful.

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?

Given a four-parameter mutation tool with a 100% covered schema and an output schema, the description supplies the critical multipart body layout, return behavior, sibling routing, idempotency warning, and dry-run validation. Nothing an agent needs in order to call it correctly appears to be missing.

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

Parameters5/5

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

Schema coverage is 100%, so the schema already documents projectId, testRunId, and dry_run. The description still adds important meaning beyond the terse requestBody schema by explaining that requestBody.resource.data holds one metadata entry per file and requestBody.files holds base64 bytes at matching array indices, which is essential for correct invocation.

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: uploading one or more new files as attachments of a Test Run in a multipart request. It explicitly distinguishes this from the sibling tools patchTestRunAttachment and getTestRunAttachments, so an agent can identify the correct tool 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 gives explicit when-to-use guidance: use this to add files, use patchTestRunAttachment to change an existing attachment, and use getTestRunAttachments to list existing attachments. The dry_run tip adds a concrete safe validation step before invoking the mutating call.

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