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 usefully adds that this is a daily snapshot mirroring a specific web page and defines the Pressure Index sign convention ('high = broad, long-end-led sovereign sell-off'), but says nothing about freshness guarantees beyond 'Daily' or the response shape.

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?

Everything sits in one dense sentence that front-loads the board name before listing metrics; every clause specifies concrete return content rather than filler. It is a bit run-on, but no sentence 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 conveying return content, and it lists the metric families (aggregated yields, slopes, per-country changes, Pressure Index) thoroughly enough for an agent to decide on and interpret the call. Missing only details like field labels or the geographic breakdown order, which are minor.

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?

The tool takes zero parameters, so there is nothing for the description to explain and the baseline of 4 applies. No parameter-level ambiguity exists.

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 artifact (Closelooknet's Sovereign Pressure board) and enumerates its contents — G7 10Y/30Y yields, 10s30s and 2s10s slopes, per-country 2Y/10Y/30Y levels/changes, and a z-scored Pressure Index — so the agent knows exactly what data this returns. It doesn't explicitly contrast itself with neighbors like get_credit_stress or get_macro_regime, but the subject matter is unambiguous.

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?

Usage is only implied: an agent can infer it should call this when sovereign-debt pressure is relevant, and the closing 'Daily.' signals the update cadence. There is no explicit when-to-use/when-not guidance and no alternative sibling (e.g. get_credit_stress) is referenced, leaving routing to inference.

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