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

No annotations exist, so the description carries the full burden, and it delivers meaningful traits: it declares the operation read-only and — importantly — that website widget settings load from the server while button styling is not stored server-side (so the returned HTML is static for buttons). It omits return shape and permission needs, keeping it from a 5.

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 led by the core output (HTML to paste on a site for a channel), with the variants following. Dense and mostly waste-free, though the telegraphic style and parentheticals make it slightly harder to parse than a cleaner sentence would.

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?

With 8 parameters, no annotations, and no output schema, the description does cover the three variants and the read-only nature, but it never says what the return value looks like (raw HTML string, object, per-variant fields) or auth requirements. Adequate for a get tool, but with clear gaps left to inference.

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%, so the schema already documents all eight parameters, establishing the baseline of 3. The description only echoes the grouping (text, colours, radius, size belong to the button; Slide Presenter adds a direct link) without adding format or default detail beyond the schema.

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 the resource precisely: returns HTML embed code to paste on a site for a channel, and enumerates the three variants (website widget, website button, Slide Presenter). An agent can tell what it produces. It stops short of explicitly distinguishing itself from the sibling get_presentation_embed_code, so it isn't a 5.

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?

Use is implied — you call it when you need embed HTML for a channel — but there is no explicit when-to-use/when-not or naming of alternatives such as get_presentation_embed_code or create_widget_test_page. The variant breakdown hints at selection but doesn't route the agent.

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