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

With annotations only declaring readOnlyHint=false and destructiveHint=false, the description carries the real burden and does so richly: it defines expected input (finished static HTML/CSS/JS, relative paths, index.html), forbids build steps and framework source, prescribes form markup conventions, and warns against hotlinking and base64 binary payloads.

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?

Front-loaded with purpose, then the numbered workflow, then constraints – a sensible order. It is dense and long for a single-parameter tool, with some convention detail (form fields, image import) that borders on sibling-tool territory, but nearly every sentence carries operational value.

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?

No output schema exists, yet the description states it returns the deploy_id, and it supplies prerequisites, sequencing, formatting rules and a user-facing help link. An agent has everything needed to call it and to drive the surrounding workflow 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% for the single domain parameter, so the schema already documents it. The description adds the meaningful constraint that the domain must be on the turbopress AI Launch plan, which is not in the schema and materially affects valid usage.

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 a specific verb (starts a new website deploy) and resource (domain under the turbopress AI Launch plan), and explicitly notes it returns the deploy_id. It is unmistakably distinguished from siblings deploy_put_file, deploy_preview and deploy_publish, which it names directly.

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?

Provides an explicit ordered workflow: 1) deploy_begin, 2) deploy_put_file for EVERY file, 3) deploy_preview plus showing the preview link and warnings, 4) deploy_publish only after explicit user confirmation. This tells the agent not just when to call this tool but how it sequences with alternatives.

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