get_running_time_entry

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

With no annotations, the description must disclose behavioral traits. It only states the basic function but does not explain what happens if no timer is running (e.g., returns null), authentication requirements, or rate limits. This is insufficient for a read operation.

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, efficient sentence that conveys the core purpose without unnecessary words. It is well-suited for quick comprehension.

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 absence of an output schema and the tool's simplicity, the description should provide hints about the return format (e.g., a single time entry object) and edge cases. It fails to do so, leaving agents with incomplete context.

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 50% because the 'assignee' parameter lacks a description. The tool description does not clarify what 'assignee' should be (e.g., user ID) or how it relates to the token owner fallback, leaving ambiguity.

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 action ('Get'), the resource ('currently running timer'), and the scope ('for a user or the token owner'). This distinguishes it from sibling tools like 'get_time_entries' (which lists all entries) and 'start_time_entry' (which creates a timer).

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 that omitting the user returns the token owner's timer, but it does not explicitly state when to use this versus alternatives like 'get_time_entries' or 'get_time_entry'. No 'when not to use' or alternative guidance is provided.

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