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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is fully covered elsewhere. The description adds nothing beyond that - no note on error behavior for a missing ID, no mention of what a 'definition' contains, and no return-shape context despite there being no output schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

One short sentence with zero padding and the key scope word ('one') up front. It is efficient, though the terseness edges toward under-specification rather than true conciseness.

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

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

For a simple single-record read with full annotation coverage and a fully described parameter, the description is minimally adequate. It leaves 'workspace event definition' undefined and gives no distinction from get-event, which is the main gap for this sibling-dense toolset.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the single 'id' parameter is documented in the schema as accepting a definition ID (etp_xxx), a name, or w:name. The description adds no further meaning, which is acceptable given the schema carries the load.

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

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

States a clear verb and resource ('Retrieve one workspace event definition'), and the word 'one' signals single-item retrieval versus list-workspace-events. However, it does not differentiate itself from the sibling get-event, and 'definition' is unexplained, so an agent must guess at the boundary between the two getters.

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

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

There is no guidance on when to use this versus list-workspace-events, get-event, or create/update-workspace-event. The agent must infer usage purely from the name and the single required 'id' parameter.

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