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

With no annotations, the description must carry the behavioral burden. It does disclose that it is an inspection of search-engine state plus setup-steps retrieval, and importantly notes the owner signs up externally and Plinth shares no data — useful privacy/ownership context. However it omits whether the call mutates anything, auth requirements, or rate/scope 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?

Purpose is front-loaded, which is good, but the single long sentence packs in OpenSEO marketing ('keyword research, rank tracking, backlinks, site audits') that is not needed to invoke the tool correctly. The parenthetical artifact list is justified; the product pitch is filler.

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 and no annotations, the description compensates reasonably by naming what the check returns (the audited artifacts) and what the setup step yields. It is nearly complete for a two-param, read-oriented tool, though it could clarify the shape of the 'steps' and whether anything on the environment changes.

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 100%, so both params are already documented in the schema; baseline 3 applies. The description only loosely references 'an environment', adding no syntax or constraint detail beyond what 'env' already provides in the schema.

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-plus-resource: 'Check how search engines see an environment' with concrete artifacts enumerated (title, description, robots.txt, sitemap, noindex), plus a clear second function (get steps to connect OpenSEO). It is distinct from every sibling since no other SEO tool exists. The dual audit/setup framing is slightly sprawling but still specific.

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 explicit when-to-use guidance or prerequisites ('run before launch', 'run per environment'). There are no sibling alternatives to disambiguate against, but the description never says under what condition an agent should invoke this versus simply reading env.status or logs.query. Usage is only weakly implied.

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