twilio_list_errors

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

With no annotations at all, the description carries the full burden. It usefully discloses the sort order ('newest first'), the account scoping, and the Beta status, but it says nothing about pagination, result caps, or what happens with warnings vs errors. The truncated tail suggests behavioral detail may have been lost.

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 productive information is front-loaded and waste-free, but the text is visibly truncated mid-word ('...err'), so the definition is fragmentary rather than deliberately concise. A dangling fragment is a structural defect, not efficiency.

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?

With no parameters and no output schema, the description is the only place an agent can learn what a returned error record contains and how many come back. Neither is covered, and the text is cut off, leaving the definition materially incomplete for a list tool.

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 takes zero parameters, which is the baseline-4 case. The description confirms the operation is implicitly scoped to 'a connected account' and needs no arguments, though it does not explain how the connected account is resolved.

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?

States a specific verb and resource: 'List the errors and warnings Twilio logged for a connected account (its debugger), newest first.' This is clearly distinct from siblings like twilio_list_calls or twilio_list_messages. The cut-off trailing text ('...err') keeps it from being a fully realized statement, but the intent is unambiguous.

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 when-to-use guidance is given; 'its debugger' only implies a debugging context. It does not say when to prefer this over twilio_get_usage or twilio_api_request, nor does it mention any prerequisites or exclusions.

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