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

Annotations already declare readOnlyHint and openWorldHint=false, so safety is covered; the description adds real context by disclosing that only 'well-sourced' reports are returned and enumerating the return fields and the full set of seven status values. It omits pagination/ordering behavior, so not a 5.

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, front-loaded with the resource and scope, and the status enumeration earns its length by telling the agent exactly what statuses to expect. Slightly heavy on commas but no filler sentences.

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 correctly carries the burden of describing the return shape (status, outlet count, first reporter, evidence link), which is the right thing to include. It could still say whether the result set is paginated or ordered, but it is largely complete for a read-only lookup.

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% with only two parameters, so the schema already documents product_slug and the category filter. The description adds no syntax, format, or example detail beyond what the schema provides, so 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+resource ('Every well-sourced pre-release report for one product') with clear scope. However, it never differentiates itself from siblings like search_reports, get_reviews, or get_release_history, so an agent must infer the boundary from the name alone.

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 'Every ... for one product' implies this is the exhaustive per-product retrieval, which hints at usage, but there is no explicit when-to-use statement and no mention of the closely related search_reports alternative for filtered lookups.

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