analyze_link_for_frontend

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

With no annotations, the description carries the full burden, and it does disclose the output shape ('a screenshot and a frontend-focused markdown analysis'), which is genuinely useful since there is no output schema. However, it says nothing about crawl behavior, runtime/cost, timeouts, or what happens with non-public or unsupported links.

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?

Two tight sentences with zero filler, and the purpose is front-loaded ahead of the return-value note. It is efficient, though its brevity leaves gaps that belong to other dimensions rather than being a structural flaw.

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 six-parameter tool with no annotations, no output schema, and near-zero schema coverage, the description is too thin. An agent knows roughly what it gets back but has no basis for setting crawl, page, text, image, or timeout options.

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?

Six parameters with only 17% schema description coverage, and the description adds almost nothing: it echoes that the url must be a public link but never explains maxPages, maxTexts, maxImages, timeoutMs, or crawlPages. It fails to compensate for the documentation gap, though the 'public link' phrasing does add a small constraint on the url.

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 specific verb and resource ('Analyze a public link ... for frontend development') and even gives a concrete example domain (Axure). It does not explicitly distinguish itself from the sibling link_health, but the frontend-analysis framing is distinct enough that an agent can infer the difference.

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 the sibling link_health as the alternative. The only implicit constraint is 'public link', which is not framed as a selection condition.

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