bill_types

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

No annotations are provided, so the description carries the full load. It notes that all bill types are returned with descriptions, implying this is a complete, safe, reference-style read. But it does not state that the tool takes no parameters or that results are static, which would fully close the behavioral picture.

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 purpose followed by a usage cue and a Returns block. Slightly more verbose than necessary for a zero-parameter reference tool, but no waste.

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 an output schema present, the description does not need to spell out return fields, and the Returns line covers the shape at a high level. For a simple zero-param reference tool this is close to complete, though it omits any note about the enumeration being fixed/static.

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?

Parameter count is 0, so the baseline is 4. Schema coverage is 100% and there is nothing for the description to disambiguate; no evidentiary basis to deduct.

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 ('Get') and resource ('types of bills'), with concrete examples (Government Bill, Private Member's Bill) so the agent knows exactly what is returned. Distinguishes itself from siblings like get_bill_by_id or search_bills by being a reference/enumeration lookup.

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?

Explicit usage context: 'Use when you need to understand different categories of legislation.' This tells the agent when to reach for it, though it doesn't name an alternative or note when not to use it.

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