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

With no annotations, the description carries the burden and does disclose the key traits: a paid operation ($7.00 / 70 credits from agent balance), an external Google Autocomplete dependency, and the exact output artifacts produced. It stops short of stating whether anything is published externally or what happens on failure for an unreachable page_url.

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 front-loaded sentence that packs purpose, method, deliverables, and price with no filler. The cost parenthetical is essential decision information, not padding.

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 no-annotation, no-output-schema tool this covers the essentials: inputs implied, outputs enumerated, and the billing consequence surfaced. Only edge-case behavior (invalid page_url, what the WordPress XML is for) is absent.

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 baseline is 3. The description ties the fixed '20 FAQs' to the max_questions default and hints at the output-family for the format param, but adds no format syntax or constraints beyond what the schema already documents.

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-plus-resource: 'Discovers customer search questions via Google Autocomplete and generates ... FAQs' with the exact deliverables (JSON-LD, HTML, WordPress XML) listed. No sibling tool does anything comparable, so the agent can immediately tell this is the content-generation tool rather than an audit/check tool.

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 only implied by the required page_url and the 'target product or service page' framing; there is no statement of when to choose this over siblings like run_full_seo_audit or run_keyword_report. Nothing is misleading, but the agent must infer the scenario.

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