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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds meaningful context that this returns the public catalog view (not drafts/internal state) and only covers Replo-managed products, but says nothing about freshness guarantees, auth scope, or 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?

A single front-loaded sentence with no filler; the qualifiers ("current", "public catalog") each carry meaning. It is well-sized for a simple getter, though it leaves no room for the disambiguation an agent would want.

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?

Wait-adjusted: for a one-parameter read-only getter with full annotation coverage and no output schema, the essential call decision (which product, read-only, idempotent) is conveyed. The remaining gap is return-shape detail, which is modest for a catalog-detail fetch.

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 0%, so the schema only gives the type (uuid) and required flag for productId. The description contributes that the ID must identify a Replo-managed product, which narrows the valid domain, but adds no format, sourcing, or error semantics.

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?

Specific verb ("Retrieve") plus a scoped resource ("current public catalog details for a specific Replo-managed product"), which clearly separates it from find_products (search) and update_product (mutation). It does not name those siblings explicitly, so an agent still infers the boundary rather than being told.

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?

No statement of when to prefer this over find_products or get_order, and no prerequisites or failure conditions (e.g., what happens with an unknown or unpublished productId). The phrase "specific ... product" weakly implies a single-record lookup by ID, but usage is left to inference.

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