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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=false. The description adds that the tool 'save's and produces a shareable URL, which confirms a write operation with a side effect (persisting the deck). However, it does not disclose whether the tool overwrites existing decks, requires authentication, or how the URL is scoped (e.g., public vs. private). With annotations already hinting at non-destructive but non-idempotent behavior, the description adds modest clarity about the result but lacks deeper behavioral context.

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?

The description is a single sentence that efficiently states the action and the outcome. Every word adds value; there is no fluff. It could be slightly more structured (e.g., front-loading the action more clearly), but it is appropriately sized for a two-parameter tool with no output schema.

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?

Given the tool's moderate complexity (2 required params, no output schema, no nested objects), the description is somewhat incomplete. It does not explain return format (e.g., the structure of the URL), error conditions (e.g., invalid HTML), or whether the deck is publicly accessible. With annotations providing limited behavioral hints, the description leaves gaps for an AI agent to infer correctly.

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% (both 'html' and 'title' are described with basic descriptions). The description does not add new meaning beyond 'HTML content to host' and 'Title for the document.' It does not clarify edge cases like required format for HTML, allowed characters in title, or size limits. Since schema already covers what the parameters are, a baseline of 3 is appropriate.

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?

The description clearly states a specific action ('save a presentation deck') and the main outcome ('get a shareable URL'). It distinguishes itself from siblings like 'create_template' (which creates a reusable template, not a deck) and 'download_pdf' (which downloads, not saves). However, it could be slightly more precise about what 'save' entails versus just hosting the HTML as an intermediary step.

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 implies usage for saving/publishing a deck and getting a URL, but it does not explicitly state when to use this versus alternatives like 'fill_template' (which uses a template to generate HTML) or 'create_template' (which creates a reusable template). There is no guidance on prerequisites (e.g., HTML already generated from a template) or when NOT to use it.

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