op_list_activities

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

The annotations already cover safety semantics with readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds that the result is a list of comments and activities for a work package, but omits details like pagination, ordering, or permission requirements; it is consistent and adequate, though 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.

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

The description is one front-loaded sentence with no filler. Every word contributes to identifying the operation and target resource.

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 one-parameter, read-only tool with comprehensive annotations, the description plus schema is largely sufficient. However, the lack of an output schema and absence of any usage/alternative guidance leave minor gaps about the exact return shape and when to choose this tool over related activities/list tools.

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 coverage is 100%, and the schema already documents 'id' as 'Work package id.' The description references 'a work package,' aligning with the parameter, but does not add further semantics such as required-ness or any additional constraints, which is acceptable for a single parameter.

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 uses a clear verb ('List') and a specific resource ('comments and activities on a work package'), so an agent can identify the operation. It does not explicitly contrast with sibling tools such as op_list_time_entry_activities or op_list_work_packages, so it stops short of the highest sibling-differentiation standard.

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 tool versus alternatives such as op_get_work_package, op_comment_work_package, or op_list_time_entry_activities. No conditions, exclusions, or prerequisites are stated, so the agent must infer usage from the name and resource.

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