pause_chore_timer

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

The description does not disclose behavioral details beyond the bare action. With no annotations, the agent lacks insight into state changes, side effects, or whether the timer can be resumed. The description carries the full burden but fails to provide sufficient transparency.

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 concise with a single sentence, no redundancy. However, it could be slightly expanded to include vital usage context without losing conciseness.

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 one-parameter tool with no output schema, the description should still explain the effect of pausing (e.g., timer stops, can be resumed) and any preconditions. The current description lacks this context, leaving the agent underinformed.

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%, so the description could rely on the schema. However, the description adds no additional meaning to 'chore_id' beyond what the schema already provides. Baseline score of 3 is appropriate.

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 verb ('Pause') and resource ('time tracker for a chore'), making the tool's purpose unambiguous. It effectively distinguishes from related tools like 'start_chore_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?

No guidance is provided on when to use this tool versus alternatives or prerequisites. The agent is not informed that the timer must be running to pause, nor when to choose pause over stop or complete.

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