Analyze Intertie Utilization

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive. The description adds useful behavioral nuance by clarifying that the output is a proxy (gross offers vs capability) and not metered flow, which helps set expectations about what the metric means. No annotation contradiction exists.

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?

Two sentences, front-loaded with the core purpose, followed by an important caveat. There is no redundancy or filler; every sentence earns its place.

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 output schema present and annotations covering read-only safety, the description need not explain return values or idempotency. It communicates the analytical intent and distinguishes the tool from metered-flow alternatives. However, the optional interties parameter's semantics are not explicitly tied to 'path and direction', leaving a minor gap in fully instructing 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 explain start_date, end_date, or the optional interties parameter. Although the schema provides types and requiredness, the description leaves the meaning of interties and the behavior when omitted implicit, forcing the agent to infer domain knowledge rather than providing clear parameter guidance.

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 uses a specific verb ('Summarizes') and a precise resource ('gross offers relative to available intertie transfer capability by path and direction'). It also clearly distinguishes itself from metered-flow tools by stating it is an offer-to-capability proxy, not metered flow, which separates it from sibling tools like get_metered_volumes and get_interchange.

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 implies when to use the tool: when the user wants an offer-to-capability proxy rather than actual metered flow. However, it does not explicitly name alternatives or state when not to use it, so an agent must infer the usage boundary from the phrase 'not metered flow' rather than receive explicit routing guidance.

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