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

Annotations already declare readOnlyHint and openWorldHint, so safety/network posture is covered. The description adds real value only by characterizing the output as a "prioritized, ready-to-act report" and by scoping the audit to four categories; it says nothing about crawl depth, page counts, runtime, or whether a URL must be publicly reachable. No contradiction with annotations.

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?

The description is one sentence duplicated almost verbatim (with an orphaned ellipsis mid-text), which is wasted space rather than conciseness. Only the trailing "prioritized, ready-to-act report" clause and the dimension list carry information; the rest is repetition.

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 an open-world, nested-object tool with no output schema, the description should at minimum explain the input payload shape and what the report contains. It provides neither, so the agent has a stated purpose but no actionable call semantics.

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 nominal 100% schema coverage is misleading: the single `input` property is a free-form nested object whose only description is "Input for ... See https://apify.com/noniner/ai-website-audit." — no field names, no shape, no required keys. The description does not compensate by explaining what the input object should contain, leaving the agent unable to construct a call from the definition alone.

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 concrete verb and resource ("audit any website") and enumerates the four audit dimensions (SEO, performance, accessibility, conversion), so the agent knows exactly what the tool produces. It fails to differentiate from the near-duplicate sibling ai_seo_site_auditor, which an agent selecting between them would need.

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 when-to-use guidance, no prerequisites, and no mention of alternatives — notably ai_seo_site_auditor and website_to_markdown, which overlap heavily. The agent must infer selection from the name alone.

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