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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds that it returns a classification (supportive/neutral/headwind), but says nothing about freshness, caching, or failure modes; with an output schema present, partial return detail is expected, so a 3 is appropriate.

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?

One dense sentence that front-loads the resource identity before listing contents and the return classification. Every clause carries content, though the long comma-separated series list makes it slightly harder to scan than a shorter statement would be.

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 parameters and an output schema present, the description only needs to convey scope and framing, which it does by naming the indicator families and the dashboard location it complements. Minor gaps remain — no cadence/freshness note and no explicit statement that no filtering is possible — but nothing an agent needs to invoke it is missing.

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?

There are zero parameters, so the baseline of 4 applies — there is no parameter semantics to explain or omit. The description correctly spends no effort on arguments and instead characterizes the payload.

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 resource (inflation pillar indicators) and enumerates the exact series covered — headline/core CPI, headline/core PCE (YoY/MoM), 5Y/10Y breakevens, wage growth. It also anchors itself against siblings by identifying it as the detail behind the Prices row of get_dashboard, so an agent can distinguish it from get_growth_indicators and get_prices.

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 phrase 'the detail behind the Prices row of the Business cycle card of get_dashboard' tells the agent exactly when this tool is the right drill-down rather than a sibling. There is no explicit when-not or mention of an alternative drill-down tool, so it stops short of a 5.

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