deleteLinkedWorkItems

DestructiveIdempotent

Deletes direct outgoing links to other Work Items in a Polarion project, including batch or full-collection removal. Use dry_run first to validate arguments and preview the irreversible change.

Instructions

Deletes the direct outgoing links to other Work Items. (The same as the corresponding Java API method.) Does not pertain to external links or backlinks. Cardinality: targets the full collection or a batch. For a single item by ID, use deleteLinkedWorkItem 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.
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.
workItemIdYesThe Work Item's ID within its project (e.g. `WI-123`), not the combined `project/id` path used in some link payloads.
requestBodyYesThe Linked Work Item(s) body.

TDQS

A4.5/5.0
Behavior5/5

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

Annotations already declare destructive=true and idempotent=true, and the description adds meaningful context beyond that: the deletion is irreversible and cannot be recovered through the API, its scope is limited to direct outgoing links, and dry_run returns a preview without sending the request.

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 and efficient: it states what is deleted, what is excluded, the batch alternative, the irreversible effect, and the dry_run tip. The parenthetical Java API reference and the executor output note are slightly extraneous but do not obscure the main guidance.

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 destructive batch-delete tool with no output schema, the definition covers scope, irreversibility, alternative tooling, and dry_run preview behavior. It does not describe success response behavior or partial-batch failure semantics, but the schema is fully described and the description is otherwise sufficient for correct invocation.

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 already documents projectId, workItemId, requestBody, and dry_run in detail. The description adds cardinality and dry_run guidance, but does not materially explain the nested requestBody structure beyond what the schema provides.

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: deletes direct outgoing links to other Work Items. It clearly limits scope by excluding external links and backlinks, and distinguishes the batch/full-collection behavior from the single-item sibling deleteLinkedWorkItem.

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 explicitly routes single-item deletion to deleteLinkedWorkItem and states what this tool does not handle (external links and backlinks). The dry_run tip gives concrete guidance for validating before an irreversible batch deletion.

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