get_tricount_summary

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

No annotations are provided, so the description carries the full burden. It does disclose the returned content well (an overview with balances and settlement transfers), but it omits whether this is strictly read-only, whether authentication/connection is required, and any rate-limit or failure behavior.

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 definition is two compact sentences, front-loading the purpose before the argument detail. No filler, though the Args block is minimal for a single parameter.

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 no output schema, the description helpfully enumerates the return fields, which is a real strength. But with no annotations and no note about auth/connection requirements or why the sole parameter is optional, it is only adequate for a read tool in a connected service.

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%, so the description must compensate. It does explain the parameter accepts either a link (https://tricount.com/tXXXX) or a key, which adds real meaning beyond the bare string/null schema. However, it does not clarify that the parameter is optional (required=false, default null), which is a meaningful gap.

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 states a specific verb+resource ('Resumen de un tricount') and enumerates exactly what the summary contains (title, currency, members, total, balances, suggested transfers). This distinguishes it from sibling tools like list_expenses or get_member_detail, though it never names those siblings explicitly.

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?

There is no guidance on when to use this tool versus alternatives such as list_expenses or get_member_detail. Usage is only implied by the word 'summary', and no prerequisites or exclusions are given.

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