rest_call

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

With no annotations, the description must disclose behavioral traits. It vaguely mentions 'data retrieval or updates' but omits critical details like authentication requirements, rate limits, side effects, error handling, or response format. This leaves significant ambiguity for an agent.

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 at one sentence (13 words) and front-loaded. It earns its place by being succinct, though it sacrifices informational depth.

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 tool with 4 parameters and no output schema or annotations, the description is insufficient. It fails to explain response behavior, error handling, or security implications, leaving an agent with inadequate context to use it safely and effectively.

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 input schema already describes each parameter. The description adds no extra meaning beyond 'RESTful API call' and does not clarify parameter semantics such as expected formats for headers/body or the effect of the method parameter.

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 tool makes a RESTful API call for data retrieval or updates, specifying the verb and resource. Among many sibling tools specialized in specific domains, 'rest_call' stands out as a generic HTTP client, making its purpose distinct.

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., other data-fetching tools like 'search' or 'get_calendar_events_list'). There are no when-not-to-use conditions or prerequisites mentioned.

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