timer_timer_delete

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

The description only states deletion and the return value, but with no annotations, it fails to disclose destructive nature, irreversibility, or error behavior (e.g., what happens if timer doesn't exist). The agent is left uninformed about side effects.

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 very short and front-loaded with the essential action and return type. The length is appropriate for a simple tool, though the '[timer]' prefix seems redundant with the tool name.

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 delete operation, the description covers the basic action and result. However, it omits behavior on missing timer (e.g., error or false return) and does not mention any required permissions or prerequisites, leaving moderate gaps.

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 input schema has a required parameter 'name' with no description, and the tool description does not clarify what 'name' refers to (e.g., timer identifier, label). With 0% schema description coverage, the description adds no meaning beyond the schema.

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 'Delete a timer' with a specific verb and resource, and indicates the return type as {deleted: bool}. This differentiates it from sibling timer tools like stop, start, or reset.

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 (e.g., timer_timer_stop, timer_timer_reset). The agent receives no context for appropriate usage.

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