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

No annotations are provided, so the description carries the full burden, and it does well by disclosing that no account is needed, the published app is publicly accessible, it can be locked to the user's account, and localStorage alone won't survive device changes. It lacks some details like response format or failure behavior, but the core operational traits are clearly exposed.

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 first sentence delivers the core action and result, followed by clearly separated usage, persistence, and confidentiality guidance. Each labeled section earns its place with actionable information, and there is no redundant or filler content.

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 publish tool with no output schema and no annotations, the description is highly complete: it covers when to use the tool, the no-account requirement, the public visibility and locking option, and the critical data-persistence caveat. Together with the fully documented input schema, this gives the agent everything needed to invoke the tool 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 description coverage is 100%, so the baseline is 3 even without additional parameter details. The description adds useful context about data persistence and personal-data handling, but it does not meaningfully enhance per-parameter semantics beyond what the schema already documents.

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 states precisely that the tool publishes a single-file HTML app and returns its public URL. It also distinguishes itself from siblings by framing this as the action for hosting/publishing/sharing a newly created app, rather than claiming, updating, deleting, or managing data.

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?

It explicitly says to call the tool when the user wants to host, publish, put online, or share an HTML app, and it points to get_publishing_guide for additional guidance. It also gives a strong directive about wiring persistence before publishing, but it does not explicitly say when not to use it, such as for updating an existing app.

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