patchWorkItemApprovals

Idempotent

Updates multiple approval entries on one Polarion Work Item from a supplied approval list. Use dry_run first to validate the request and preview changes before applying decisions.

Instructions

Updates multiple approval entries on one Work Item using the supplied approval list. Requires permission for each requested decision. Use getWorkItemApprovals to inspect current entries and patchWorkItemApproval for one approver. Cardinality: targets the full collection or a batch. For a single item by ID, use patchWorkItemApproval instead. Effect: idempotent — calling it again with the same input leaves the resource in the same end state, with no additional side effects. 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 Test Run(s) body.

TDQS

A4.6/5.0
Behavior5/5

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

Beyond the annotations, the description adds that permission is required for each requested decision, explains the batch/full-collection cardinality, and clarifies the idempotent effect with no additional side effects. The `dry_run` tip further discloses a safe preview behavior that is not captured by the idempotent or destructive hints alone.

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 operation and then layered with routing, permission, cardinality, idempotency, and dry-run guidance. It is somewhat long but nearly every sentence serves a routing or safety purpose; minor trimming could improve density.

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 batch mutation with full schema coverage and annotations covering safety hints, the description supplies the missing operational context: sibling alternatives, permission requirements, cardinality, idempotency, and dry-run validation. No output schema exists, so no return-value explanation is needed.

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 parameters are already well documented in the schema itself. The description reinforces that the request body is an approval list and explains `dry_run`, but it does not add substantial parameter-level semantics 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: it updates multiple approval entries on one Work Item using a supplied approval list. It explicitly distinguishes this batch operation from `getWorkItemApprovals` and the single-approver `patchWorkItemApproval`, so an agent can identify its role 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 alternatives: use `getWorkItemApprovals` to inspect current entries, use `patchWorkItemApproval` for one approver, and use `patchWorkItemApproval` instead when targeting a single item by ID. It also recommends setting `dry_run: true` first to validate arguments and preview the request.

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