discord_call_endpoint

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

The description adds some behavioral context beyond annotations: it indicates that the tool validates the endpoint before calling, and only 'cataloged' endpoints are allowed. However, it does not disclose the confirmation flow, potential side effects of calling, or any authentication/rate-limit considerations. The annotations already indicate non-read-only and open-world semantics, so the bar is lower, but there is room for more detail.

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, efficiently worded sentence that front-loads the action and resource. It is appropriately concise, though given the tool's complexity it might benefit from more detail, but the structure itself is clear.

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?

Despite having annotations, the description is too sparse for a tool that executes external HTTP calls. It does not explain the purpose of the confirm flag, how files or body are used, what the reason field is for, or what outputs are expected. The absence of an output schema and 0% parameter coverage makes this description insufficient for safe and correct invocation.

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 description coverage is 0%, and the description does not compensate for the 7 parameters. It only mentions 'endpoint' by name without explaining its significance or the roles of body, files, confirm, reason, pathParameters, or queryParameters. This leaves the agent to infer meanings from parameter names alone, which is inadequate.

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 ('Validate and call') and the resource ('one cataloged Discord Bot HTTP endpoint'). It distinguishes this tool from siblings by focusing on executing an endpoint rather than searching, retrieving, or refreshing schema.

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 provides no explicit guidance on when to use this tool versus alternatives. It does not mention sibling tools or any prerequisites, exclusions, or decision factors. There is no 'use when' or 'instead of' context.

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