Deploy Static HTML Site

deploy-static-html-site

Deploy static HTML by creating a Google Compute Engine VM that runs nginx and serves your content.

Instructions

Create a VM with a startup script that installs nginx and writes provided HTML to /var/www/html/index.html

B3.3/5.0

Behavior3/5

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

With no annotations provided, the description carries the full burden. It does disclose key behavioral side effects: it creates a VM, installs nginx, and writes the HTML file to a specific path. However, it omits operational implications such as cost, startup delay, whether a public IP is created, or how the deployment can be verified.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that efficiently captures the core mechanism: VM creation, nginx installation, and HTML file placement. There is no filler or redundant restatement of the tool name.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The core deployment behavior is adequately described, but there is no output schema and no annotations, so the agent is left without guidance on return values, post-deployment access, or failure modes. For a resource-creating operation, this leaves meaningful gaps in what an agent needs to fully use the result.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the input schema already documents all four parameters. The description adds only a mild restatement of the htmlContent role and does not provide extra meaning beyond the schema. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific action—creating a VM with a startup script that installs nginx and writes HTML content—so the agent knows exactly what this tool does. It implicitly differentiates from bucket-based static-site siblings by specifying the VM/nginx approach, but it does not explicitly contrast itself with near-sibling deploy-static-site-from-html.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to prefer this tool over alternatives such as deploy-static-site-from-html, create-static-site-bucket, or gcp-compute-create-instance. The description implies a VM-based deployment scenario but provides no explicit when-to-use or when-not-to-use conditions.

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