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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is covered. The description adds genuinely useful context beyond that: the overallScore is a four-persona consensus explicitly not a UX score (with a legacy field-name caveat), and the content is editorial/curated rather than a live capture, with an explicit prompt-injection warning to treat text as data.

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?

Front-loaded with the core purpose, then a compact field enumeration and two caveats. It is a dense single paragraph with no filler, though the uxScore-renaming parenthetical is slightly verbose for the value it adds.

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 carries the burden of describing the return shape and does so by naming every field, plus flagging the non-obvious overallScore semantics. What is missing is only the routing context relative to its four sibling tools.

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?

There are zero parameters, so per the rubric the baseline is 4. The description correctly adds no parameter semantics and instead spends its space on return-field meaning.

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 (List) and resource (curated sample product teardowns from coExploro), and enumerates the returned fields. However, it never distinguishes itself from the sibling list_corpus_teardowns, so an agent must infer the public-vs-corpus split 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?

There is no when-to-use guidance and no mention of alternatives such as list_corpus_teardowns or the get_* siblings. The agent is left to infer that this is the browse-all entry point and that a single teardown requires a different tool.

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