eventstream_update

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

Annotations indicate destructiveHint=true and readOnlyHint=false, which align with 'Update.' The description adds value by noting that 'Authentication is handled transparently using Azure Identity,' providing context beyond annotations. However, it does not detail side effects or return format.

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?

The description is concise, with a clear docstring format. It includes essential information (purpose, auth, param docs) without extraneous content. The structure is front-loaded with the main action.

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?

Given the tool has 3 simple parameters and an output schema (not described), the description covers purpose, auth, and param meanings. It lacks explanation of the output structure and potential partial updates, but is otherwise sufficient for a simple update operation.

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 0%, but the description includes a docstring explaining each parameter: workspace_id (UUID), item_id (UUID), and definition (updated eventstream definition). This adds meaning beyond the schema's types and titles. The return value is mentioned but not parameter-specific.

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?

The description explicitly states 'Update an Eventstream item by workspace and item ID,' clearly specifying the verb (update), resource (Eventstream item), and identifiers (workspace and item ID). Among sibling tools, this distinguishes it from create, delete, and get operations.

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?

The description implies usage when updating an existing eventstream item but does not provide explicit guidance on when to use versus alternatives (e.g., create, delete), nor does it state prerequisites or exclusion conditions.

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