Egypt economic indicators

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered. The description adds the notable behavioral fact that results carry Thndr's own source descriptions and that both headline readings and series points come back together, but it says nothing about rate limits, refresh cadence, or how much data volume to expect.

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 sentence that front-loads the critical scoping constraint ('Egypt only') before the enumeration. The nested list of indicators is dense and slightly run-on, but every clause names actual return content, so little is wasted.

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 carries the burden of describing returns and does so thoroughly by enumerating the headline metrics and series. The only gap is that it never states the effect of the `points` parameter on payload size, though the schema covers that.

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% and the single `points` parameter is fully documented in the schema (default 12, min 1, max 500). The description's phrase 'the latest points of the ... series' loosely corroborates the parameter's meaning but adds no format, units, or edge-case detail beyond the schema, so the 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 resource (Egypt macroeconomic data) and enumerates the exact readings returned: inflation, CBE deposit/lending rates, T-bill yield, unemployment, GDP, plus series history. The 'Egypt only' scope and the Thndr-specific framing make it unmistakable against every sibling, none of which touch macro data.

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 'Egypt only' scoping constraint tells the agent the applicability boundary, which is real guidance. However, there is no explicit when-to-use vs when-not framing and no mention of alternatives (there are none among siblings), so usage is only implied rather than directed.

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