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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds the endpoint (GET /transactions) and the returned field set, but says nothing about paging behavior or result ordering beyond what the schema already documents.

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?

A single compact line that leads with the operation and resource, then lists the fields, then the endpoint. No filler and nothing buried.

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, enumerating the returned fields (type, amount, date, vendor, category, links, description) is genuinely useful and covers the return shape. Pagination and filtering details live in the schema, so nothing critical is missing, though the absence of any note about paging through results is a minor 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?

Schema description coverage is 100%, including a detailed explanation of the nested filters object and its silent-ignore behavior, so the schema carries the parameter burden. The description adds no parameter-level meaning (e.g. which field names are valid in filters, useful sort_by values), so baseline 3 applies.

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?

Names a specific verb (List) and resource (income/expense transactions), and enumerates the fields returned so the agent knows the payload shape. It is distinguishable from farmbrite_get_transaction and farmbrite_create_transaction by the plural 'List', though neither sibling is named 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 versus farmbrite_get_transaction (single record) or farmbrite_list_activities, and no stated preconditions. Usage is only inferable from the tool name and the word 'List'.

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