bulk_update_activity_status

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

With no annotations, the description still discloses important behavioral traits: the 100-ID chunk limit, the failed-array inspection requirement, safe retry semantics for failed chunks, and the activity-status versus task-status distinction. It does not explicitly discuss permissions, whether the update is reversible, or the full response shape, so it falls short of fully carrying the behavioral burden for a mutation tool.

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?

Three tightly packed sentences front-load the operation, then give prerequisites, limits, and failure handling. Every sentence contributes actionable guidance with no repetition or filler.

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 bulk mutation with no annotations and no output schema, the description covers the essential workflow, the 100-item limit, status resolution, and failed-array handling. It stops short of describing the full return payload or permission requirements, but it provides enough to call the tool correctly and safely retry failed chunks.

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%, so the schema already documents all five parameters and the statusId/statusName alternative. The description adds meaningful context beyond the schema by naming the reference-data entity for activity statuses and distinguishing them from task statuses, though it does not elaborate on projectMethodTypeId or serviceId semantics beyond what the schema provides.

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 opens with a specific verb and resource: "Apply one status to many activities of a service in a single call." It clearly distinguishes a bulk activity-status mutation from singular update_activity and from task-status operations elsewhere. An agent can identify the operation 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.

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

It explicitly prescribes the workflow: collect activity IDs via list_service_activities, chunk into calls of at most 100 IDs, and resolve status IDs via get_reference_data with entity "activitystatuses" or pass statusName. It also warns that activity statuses differ from task statuses and directs the agent to check the failed array, including that retrying a failed chunk is safe.

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