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

readOnlyHint=true already tells the agent this is a safe read, and the description corroborates it by framing the call as a retrieval. The parenthetical '(all products, current)' usefully signals return scope (no historical entries), but nothing is said about behavior for unknown domains, empty results, or result size.

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 sentence, front-loaded with the action and resource, with the input requirement and example trailing. Every clause carries information and nothing is padded.

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?

For a one-parameter read tool with no output schema, the description covers what is fetched and how it is identified. Return shape and error behavior for an unknown domain remain unspecified, which is the only meaningful gap.

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?

With 0% schema description coverage, the description must carry the parameter alone, and it does: the single 'domain' argument is defined as the company's domain with a concrete example ('example.com'). That removes the main ambiguity (bare name vs. URL vs. full domain) without spelling out accepted formats like scheme prefixes.

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 ('Get') plus a specific resource ('a company's complete AgentDNA catalog') and an explicit scoping qualifier ('all products, current') keyed by domain. It does not differentiate itself from siblings like agentify_search or agentify_get, so an agent cannot tell from the description alone when this beats searching.

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?

Usage is implied: fetch the full catalog for a known company domain, with 'example.com' as an example input. There are no explicit exclusions and no mention of the sibling tools (agentify_get, agentify_search, agentify_stats) that might be the better choice for partial lookups.

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