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

Annotations already cover read-only/closed-world/non-destructive, so the description correctly spends its budget elsewhere: it discloses that the content is curated editorial rather than a live capture and warns the agent to treat its text as data, not instructions — a genuinely useful safety note. It does not discuss pagination or result size limits.

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: the first front-loads what the tool returns, the second supplies safety framing. The long parenthetical about overallScore vs. uxScore naming is detailed but earns its place since it prevents a real misinterpretation of the returned score.

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 compensates by enumerating the fields each item carries and clarifying the ambiguous overallScore/uxScore naming, and it adds an injection warning. Complete enough for a zero-parameter list tool; pagination behavior remains unstated.

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?

Zero parameters, so the schema baseline is a 4. The description instead documents the returned item fields (slug, companyName, overallScore, personaSummary, etc.), which is output semantics rather than parameter semantics and adds no parameter information because none exists.

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 and resource ('List the curated sample product teardowns') and scopes it to coExploro's public catalog. It does not, however, distinguish itself from the sibling list_corpus_teardowns or the get_*_teardown tools, leaving the 'public' vs 'corpus' vs 'shared' split to inference.

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 conditional guidance about when to call this versus list_corpus_teardowns or get_public_teardown. The name implies a listing operation, but no alternatives, prerequisites, or exclusions are given.

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