get_basin

Get the drainage area upstream of a hydrologic site. Compute it from the delineated boundary, or use the surveyed area when published for the site.

Instructions

The area draining to a point. The area is computed from the delineated boundary rather than published; where a site record also states a drainage area, that figure is surveyed and is the one to quote.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Behavior3/5

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

With no annotations provided, the description bears full responsibility for behavioral disclosure. It does reveal that the area is computed from a delineated boundary rather than published, and that in cases where a surveyed figure exists, that is the one to quote. This is useful nuance that helps the agent interpret results but does not cover other behaviors like output format or error cases.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is only two sentences and 36 words, which is appropriately brief. However, the first sentence is more of a definition than a functional explanation, and the second sentence could be clearer. Still, no filler words are present.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite having a single parameter and no output schema, the description is insufficient. It does not explain what 'identifier' refers to, what the returned data looks like, or how this ties into the hydrological domain. Sibling tools suggest a complex system, but this tool's description leaves out critical details an agent would need to invoke it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has one parameter 'identifier' with no description, and schema description coverage is 0%. The description does not mention the parameter at all, leaving the agent without any clue about what value to supply (e.g., a station ID? coordinates?). This is a critical gap that the description needed to address.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'The area draining to a point' defines a watershed but does not clearly state the tool's action (e.g., 'get' or 'retrieve'). It fails to specify that the tool returns the basin for a given identifier, leaving the purpose ambiguous. The second sentence adds detail about computation but not what the tool does.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given on when to use this tool versus siblings like get_latest or get_series. The description does not mention prerequisites, typical use cases, or alternatives. The only context is a note about 'where a site record also states a drainage area,' but it stops short of explaining when to call this tool.

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