deployment_pipeline_unassign_workspace

Destructive

Unassign a workspace from a deployment pipeline stage to reorganize stage assignments. Specify pipeline ID, stage ID, and workspace ID for the operation.

A3.5/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=false and destructiveHint=true. The description clarifies that the destructive action is an unassignment rather than a workspace deletion, which adds useful context, but it does not mention side effects, reversibility, or whether the action is asynchronous. Given the annotation coverage, this is adequate but not rich.

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 a single focused sentence with no filler. The verb and object are front-loaded, and every word contributes to the tool's meaning.

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

Completeness3/5

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

For a simple three-parameter mutating tool with complete schema and annotations, the description is nearly sufficient. However, it omits caveats such as whether a stage must contain the workspace before unassignment, whether unassignment can affect deployment, or how to confirm success. Since there is no output schema, a bit more operational context would improve completeness.

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?

The input schema has 100% description coverage for all three parameters, so the schema already documents their meaning. The description adds no additional parameter-level semantics, which is acceptable but not additive.

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 precise operation: 'Unassign a workspace from a deployment pipeline stage.' It includes the verb, the object being acted on, and the containing resource, and it clearly differentiates from the inverse sibling deployment_pipeline_assign_workspace.

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 is given about when to use this tool versus alternatives such as deployment_pipeline_assign_workspace or deployment_pipeline_list_stage_items. There are no prerequisites, exclusions, or conditions stated, so the agent must infer usage entirely from the tool name.

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