redmine_list_time_entry_activities

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

The description only states the operation and does not disclose behavioral traits such as read-only nature, return format, pagination, or any prerequisites. Since no annotations are provided, the description carries the full burden but provides minimal context beyond the basic action.

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 a single, front-loaded sentence with no filler or redundancy. It is appropriately sized for a simple parameterless tool.

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?

The description tells what the tool does but lacks any elaboration on output structure, usage context, or relationship to siblings. For a simple parameterless list operation it is minimally viable, but the absence of annotations or output schema means more context would help.

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?

The tool has zero parameters and the schema coverage is 100% (empty). Per the baseline rule for 0 params, the description does not need to add parameter meaning. It correctly avoids inventing parameters.

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 'List available time entry activities' uses a specific verb (list) and resource (time entry activities), clearly distinguishing it from sibling tools like 'redmine_list_time_entries' which lists actual time entries rather than activity types.

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 guidance is provided on when to use this tool versus alternatives. The sibling list contains similar list operations (e.g., list_time_entries, list_statuses), but the description does not clarify the specific use case or relationship between them.

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