get_site_details

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

Annotations already declare readOnly, idempotent, non-destructive, open-world behavior, so the safety profile is covered. The description adds value beyond that by disclosing the actual returned content (palette, tech stack, elements, awards, inline screenshot), which matters since there is no output schema.

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?

A single dense sentence with the verb and resource front-loaded and zero filler; every clause (palette, technologies, elements, awards, description, screenshot) earns its place by telling the agent what comes back.

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 one-parameter read tool with full annotation coverage, the definition is nearly complete: it states the payload and the schema supplies slug format and origin. The one gap is the absence of any usage/routing guidance relative to siblings such as search_sites.

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 coverage is 100% and the slug property already carries a pattern constraint, a concrete example ('l-i-s-a') and its origin tool. The description adds nothing further about the parameter, so the baseline 3 applies.

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 (Get) plus resource (one Awwwards site) and an explicit enumeration of the payload — color palette, technologies, design elements, awards, description, screenshot. That enumeration usefully separates it from siblings like get_site_elements or get_motion_dna, though no sibling is named outright.

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?

The description gives no when-to-use, no prerequisites, and no alternatives. The only workflow cue ('slug from search_sites') lives in the input schema, not in the description, so an agent gets no routing guidance from the text itself.

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