A3.5/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds only a contents list and parameter provenance; it discloses nothing further about auth requirements, rate limits, or whether the profile is a live capture vs. stored snapshot. Adequate but not rich given the annotation floor.

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, zero filler, and the payload contents are front-loaded before the key-sourcing note. Tight and well-ordered, though the field enumeration partly duplicates the output schema.

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?

An output schema exists, so return values need no explanation, and all five parameters are fully documented in the schema. The description supplies the routing-level overview an agent needs; only sibling differentiation is missing.

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% and each parameter carries detailed guidance (page is not a URL, view is not an OS, version must be pinned, environment sourcing). The description's "stored view key from list_pages" merely echoes the schema, so baseline 3 is appropriate.

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?

States a specific verb+resource ("Get one page profile") and enumerates the profile contents (URL, title, viewport, outline, layout, fonts, themes, links), which conveys it is an aggregate summary rather than a single-facet tool. However, it never names or contrasts against close siblings such as get_page_outline or get_themes, so differentiation is left to inference.

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

Usage Guidelines3/5

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

"Use a stored view key from list_pages and the selected environment" gives a prerequisite for obtaining the view argument, which is useful context. But there is no when-to-use-this-vs-alternatives guidance, no exclusions, and no statement of when the summary is preferred over the more granular page tools.

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