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

Even though annotations already flag destructiveHint=true, the description adds crucial behavioral detail: reusing a project name redeploys in-place, hardcoded list content produces a broken build, and deploying alone is not the deliverable. It also discloses that the tool returns a live URL and references upload_media URLs rather than bundling images.

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 dense and front-loaded with the most important workflow warning. Some phrasing is conversational and lengthy, but every major clause contributes actionable information rather than filler.

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 complexity and the absence of an output schema, the description is remarkably complete: it covers prerequisites, deployment constraints, post-deploy steps, destructive redeploy behavior, required file structure, and the return value. An agent has enough guidance to call this 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 coverage is 100%, so the baseline is 3, but the description adds meaningful constraints beyond the schema: files must be HTML/CSS/JS, text-only, include index.html at the root, and reference images via upload_media URLs. It also reinforces the redeploy behavior of the name parameter.

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 that the tool deploys a multi-file website from inline file contents, with a specific resource and required index.html. It is distinguishable from the sibling deploy_website by the 'multi-file' qualifier, though it does not explicitly name that sibling or contrast itself with it.

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 gives explicit workflow context: run the build order first, then deploy, then assign_to_project and configure_chatbot. It also warns against filesystem staging and hardcoded list content, but it does not explicitly state when to choose this tool over deploy_website for single-file sites.

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