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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuine value beyond that by disclosing the scope (complete, unfiltered enumeration) and the shape of each returned record, which annotations do not convey.

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 sentence that front-loads the verb and scope, then delivers the return fields. The eight-name parenthetical is lengthy but earns its place by letting an agent match product names without an extra call.

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 compensates by naming the fields each product carries. For a zero-parameter list tool this is nearly complete; only ordering or result-size expectations are unstated, which is minor here.

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 the baseline is 4; there is nothing for the description to disambiguate. The statement that all products are returned reinforces that no filtering argument exists, which is a small but real clarification.

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 ("List") plus a precisely scoped resource (every PRIVAKU app and SDK), with the concrete members enumerated so an agent knows exactly what comes back. It also names the returned fields (slug, status, platforms, page URL), which distinguishes it from the singular sibling get_product 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?

"List every" implies this is the unfiltered catalog call, so the when-to-use case is inferable. However, no alternative is named: it never says to use get_product for a single product or fetch/get_download_links for deeper detail, leaving the routing decision to inference.

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