This tool calls the Actor "rowfeed/pagespeed-insights-api" and retrieves its output results. Actor description: Run Google PageSpeed Insights on a list of URLs: Lighthouse performance, accessibility, best-practices and SEO scores, LCP, CLS, TBT and INP, real-user Chrome data, Core Web Vitals pass/fail and the top slow-downs. Mobile and desktop.

Input Schema

Name	Required	Description	Default
`urls`	No	Web pages to test, e.g. https://example.com/ or example.com/pricing. Up to 1,000 per run. Each page is tested once per device. Example values: ["https://apify.com/"]
`device`	No	Test as a mobile phone (what Google ranks on), a desktop computer, or both (two rows per page). Example values: "mobile"	mobile
`waitSecs`	No	Max seconds (0–45, default 30) to cap the wait for the Actor run to reach terminal state. For long-running Actors the response returns at the cap with the current run status; follow `nextStep` to poll via get-actor-run. Set to 0 to fire-and-forget.

B3.2/5.0

Behavior3/5

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

Annotations already state readOnlyHint=false, openWorldHint=true and destructiveHint=true, so the agent knows this creates external state; the description does not contradict that and adds the metric set produced. However, it does not disclose that this kicks off an Actor run that may exceed the wait, that polling via nextStep/get-actor-run may be required, or that live lookups need a paid plan — those facts live only in the schema's waitSecs and top-level description fields, not here.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, with the actual capability front-loaded in the second. Efficient overall, though the first sentence is pure template boilerplate restating the tool name and could be cut without loss.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With only three optional parameters, full schema coverage and an output schema, the description need not explain return values, and it does cover what the analysis measures. The main omission is asynchronous run behavior and cost/plan requirements, which matter for an open-world Actor invocation but are covered elsewhere in the schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3; the schema already explains `urls`, `device` (with enum) and `waitSecs` including the 0–45 cap and fire-and-forget behavior. The description's mention of 'a list of URLs' and 'Mobile and desktop' lightly mirrors two parameters but adds no syntax, limits or defaults beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The second sentence names a specific analysis (Google PageSpeed Insights on a list of URLs) and enumerates the concrete outputs: Lighthouse performance, accessibility, best-practices and SEO scores, LCP, CLS, TBT, INP, real-user Chrome data and Core Web Vitals pass/fail. That is enough to distinguish it from the purely technical checker siblings. The opening sentence ('calls the Actor ... and retrieves its output results') is generic boilerplate that adds no specificity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to pick this over the many adjacent SEO siblings (rowfeed--seo-site-audit, rowfeed--google-serp-api, rowfeed--website-technology-checker), and no stated prerequisites. The only situational cue is the implicit 'list of URLs' + mobile/desktop framing, which an agent must infer.

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