Analysis — Target funding gaps

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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=false, so the '[READ]' prefix largely restates structured data. The description does add useful context that the result measures the shortfall against each goal target, but says nothing about scope limits, permissions, or result size.

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?

Three tight sentences, front-loaded with the read tag and the core resource, then the output meaning, then the parameter detail. No filler.

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?

An output schema exists, so return values need not be explained, and the month semantics are covered. However, with two parameters and zero schema coverage, leaving plan_id entirely unexplained is a real gap for a tool whose results are presumably plan-scoped.

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 documents 'month' well (ISO first-of-month format, example, current-month default), which genuinely exceeds the schema, but 'plan_id' is completely undocumented in both schema and description.

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 names a specific resource (categories with unmet funding goals) scoped to a given month, plus what the output means (how much more must be budgeted). It separates itself from sibling analyses only implicitly, though — no sibling such as analysis_credit_funding is named as an alternative.

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 '[READ]' tag and 'for a given month' framing imply this is a read-only inspection of goal shortfalls, but there is no explicit when-to-use vs. when-not, and no routing to related analyses like analysis_credit_funding or analysis_overspent_categories.

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