delete_time_entry

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

With no annotations provided, the description fully handles transparency. It clearly states that the operation is permanent and cannot be undone, and it describes the return value ('confirmation with the deleted entry id'). This is sufficient for a deletion 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: two sentences with no wasted words. The purpose is front-loaded, and every sentence adds necessary context (permanence, return value).

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 simplicity of the tool (delete by ID), the description covers all essential context: permanent effect, required parameter, and return value. Without an output schema, stating the return is helpful. No missing information for an agent to use the tool correctly.

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% (both parameters are described). The description adds no additional meaning beyond what the schema already provides (e.g., it mentions 'by id' but the schema clarifies the parameter name 'timer_id'). Baseline score applies.

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 ('Permanently delete') and the resource ('a time entry by id'). It uses a specific verb and resource, distinguishing it from sibling tools like get_time_entry or update_time_entry.

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 warns that deletion is permanent and cannot be undone, which advises caution. However, it does not explicitly state when to use this tool versus alternatives (e.g., other delete tools), nor does it mention any prerequisites.

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