projects_plan_activities_update

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

No annotations are present, so the description carries full burden. It fails to disclose behavioral traits such as whether the operation is reversible, if it triggers side effects (e.g., notifications), or any permissions required. The description is too brief 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?

The description is extremely concise, containing only two sentences with no redundant information. It front-loads the core action and follows with a specific capability (moving activities). Every word earns its place.

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 4 parameters, no output schema, and no annotations, the description is insufficiently complete. It does not mention required vs optional parameters, the behavior when only one of phase_id/group_id is specified, or what the response looks like. A mutation tool of this complexity needs more detail.

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%, providing basic descriptions for each parameter. The description adds context that phase_id and group_id are the update fields for moving activities. However, it does not clarify that id and activity_id are required, nor does it explain default behavior when only one of phase_id or group_id is provided.

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 clearly states the tool updates an activity phase or group, and explicitly mentions moving activities between phases and groups. This distinguishes it from siblings like activities_update (which likely updates other activity fields) and projects_plan_tasks_update.

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?

No explicit guidance is provided on when to use this tool versus alternatives. The description does not differentiate it from activities_update or other project plan tools, nor does it specify prerequisites or contexts where this tool is appropriate.

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