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

With no annotations provided, the description carries full disclosure burden. It successfully states 'Read-only' (safety profile) and 'Returns JSON object' (return format). However, it lacks details on error conditions, rate limits, data retention periods, or authentication requirements beyond the parameter schema.

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?

Four well-structured sentences front-load the purpose, followed by comparisons, usage guidelines, and prerequisites. Every sentence earns its place with no filler, though slightly more verbose than the exemplar tier-A benchmark.

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?

Given no output schema exists, the description adequately compensates by referencing get_pricing_dashboard to indicate return structure. With only two simple parameters (both hex IDs) and 100% schema coverage, the description provides sufficient context for invocation decisions.

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 has 100% coverage already. The description adds valuable workflow semantics by explicitly stating runId must come 'from get_pricing_history', reinforcing the dependency chain and temporal relationship between tools that pure schema descriptions cannot convey.

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 uses specific verb 'Get' with resource 'full competitor-by-competitor Pricing Intelligence data' and scope 'for a specific historical run'. It explicitly differentiates from sibling get_pricing_dashboard by stating it returns the 'same data structure... but for a past point in time', clarifying this retrieves historical snapshots versus current 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?

Provides explicit when-to-use: 'Use this to investigate pricing changes between runs or audit a specific monitoring cycle'. States prerequisite clearly: 'Requires runId from get_pricing_history'. Implicitly guides users toward get_pricing_history first and contrasts with get_pricing_dashboard (current vs historical).

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