Oracle General Info

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

Annotations already convey readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, giving the agent a strong safety profile. The description adds some context by naming the content areas covered, but it does not disclose any non-obvious behavior beyond what the annotations and output schema already imply, so the added value is modest.

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, front-loaded sentence with no filler. It conveys the domain, the specific content areas, and the intended usage ('starting point') in a compact and readable way.

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 that there are no parameters, an output schema is present, and annotations cover read-only and non-destructive behavior, the description is complete enough for an agent to invoke it appropriately. It specifies the categories of information returned and positions the tool correctly within the workflow, leaving no obvious gap.

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 has zero parameters, so there are no parameter semantics for the description to clarify. Per the rubric, a no-parameter tool receives a baseline of 4; the description appropriately focuses on what the returned information contains rather than on arguments.

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 names the resource ('PJM vs MISO Energy Arbitrage Oracle') and the type of information returned ('contract, network, TEE, pricing tiers'), giving a clear sense of purpose. It stops short of using a concrete verb like 'retrieve' and does not explicitly distinguish itself from siblings such as get_oracle_status or get_connection_info, but 'general info' and 'starting point' establish the intended role.

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 phrase 'Starting point for any agent' provides explicit guidance on when to invoke this tool: at the beginning of an agentic workflow. It does not list exclusions or direct the agent to related tools, though the sibling list implies that get_oracle_status, check_subscription, and others serve different, more specific purposes.

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