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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is covered. The description adds genuine behavioral context by naming the content categories returned (positioning, product, pricing, funding, traffic), which helps the agent judge whether the call will answer the user's question.

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?

Two sentences, no filler; the payload enumeration leads and the usage cue follows. Nothing could be removed without losing signal.

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 an output schema present, the description need not explain return structure, and the safety profile is carried by annotations. It omits any failure mode (e.g. unknown competitor_id), a minor gap for a read tool whose id must come from list_competitors.

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 coverage is 100% and the single parameter's description ('An id from list_competitors') already explains provenance. The tool description adds no syntax, format, or validity guidance beyond that, 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?

States a specific verb (gets) and resource (the dossier for one tracked competitor), then enumerates the payload: company facts, risk/opportunity, and stored reads. The 'one tracked competitor' scope distinguishes it from list_competitors without ambiguity.

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?

'Use it when the user asks about one competitor in depth' gives a clear selection condition. It does not explicitly name list_competitors as the alternative for bulk browsing, but the depth/singular framing implies the boundary well enough.

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