deleteTestRecordAttachment

DestructiveIdempotent

Deletes a specified Test Record Attachment by ID to remove unwanted files from a Polarion Test Record. Run dry_run first to validate and preview this irreversible action.

Instructions

Deletes the specified Test Record Attachment. Cardinality: targets a single item by ID. For the full collection or a batch, use deleteTestRecordAttachments instead. Effect: irreversible — data removed or overwritten by this call cannot be recovered through the API. 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.
iterationYesThe iteration number identifying which repeated occurrence of this item is being addressed (e.g. which run of a test parameter).
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.
testCaseIdYesThe Test Case's ID being referenced.
attachmentIdYesThe attachment's ID, as returned by the corresponding list- or get-attachments call for this resource.
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.

TDQS

A4.7/5.0
Behavior5/5

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

Annotations already declare destructiveHint=true, readOnlyHint=false, idempotentHint=true, and openWorldHint=true. The description adds that deletion is irreversible and that dry_run returns a preview as text and structured content, which is meaningful context beyond the annotations.

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 front-loaded with the action and scope, and each following sentence adds useful detail: batch alternative, irreversibility, and dry-run preview. No sentence is filler.

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?

For a destructive mutation with full schema coverage and no output schema, the description supplies the missing operational context: irreversibility, the batch alternative, and dry-run preview behavior. An agent has enough information to invoke it correctly.

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% for all 7 parameters, so the schema already explains each parameter's meaning. The description reinforces single-item ID targeting and the dry_run preview, but adds little parameter semantics beyond what the schema provides, so the baseline 3 is appropriate.

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?

States a specific verb and resource: 'Deletes the specified Test Record Attachment.' It then clarifies cardinality ('targets a single item by ID') and names the batch sibling deleteTestRecordAttachments, which distinguishes it cleanly from alternatives.

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?

Explicitly routes full-collection or batch deletions to deleteTestRecordAttachments and recommends setting dry_run: true first to validate and preview the request. That gives both the alternative and the safer usage pattern for a destructive call.

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