patchLinkedWorkItem

Update direct outgoing links from a work item to linked work items in Polarion, specifying role, target project, and linked work item.

Instructions

Behavior2/5

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

No annotations provided. Description does not disclose whether the update is partial or full replacement, the effect on revision/suspect fields, or any side effects. The 'same as Java API method' reference is not self-contained.

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?

Concise, with two sentences. Could be more front-loaded but generally efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 6 required parameters, a nested requestBody, and no output schema, the description lacks explanation of how the parameters interact (e.g., roleId vs targetProjectId vs linkedWorkItemId). The update semantics are unclear.

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 coverage is 100%, so the schema already documents all parameters. Description adds no additional parameter meaning beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it updates direct outgoing links to other Work Items, distinguishing from external links and backlinks. However, among siblings, it could clarify that this is for updating an existing link versus creating (post) or deleting.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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

No guidance on when to use this tool vs alternatives like postLinkedWorkItems (create) or deleteLinkedWorkItem. Only mentions exclusion of external/backlinks.

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