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

Annotations already flag destructiveHint=true, but the description discloses the concrete destructive behaviors: an empty string removes the value, turbopress overwrites both fields into the start page on every preview/publish, and subpages without their own title inherit it. It also explains that apply_now recreates a version from the live site, which is exactly the kind of side effect an agent needs before acting.

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?

Purpose is front-loaded and the paragraph is dense rather than padded. It is long for a single block, and the apply_now behavior is partly restated from the schema, but each sentence still contributes operational information.

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?

With no output schema, the description compensates by describing the read behavior (returns current values) and the deploy_id returned in the apply_now path. It also covers the consent gate before deploy_publish. Minor gaps remain: no guidance on invalid domains or sites outside the plan, and no error behavior.

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 meaning the schema lacks: an empty string deletes the value, titles should stay ≤60 characters and descriptions ≤160 (while the schema only enforces 120/320), and apply_now must be paired with a preview-then-confirm flow. Only the domain parameter gets no extra explanation.

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 names a specific verb pair ("lesen oder setzen") and a specific resource ("Seitentitel und Beschreibung") and scopes it to the turbopress AI Launch plan. No sibling tool manages SEO metadata, so the agent can distinguish it immediately from tools like set_contact_form or deploy_put_file.

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 states the read-vs-write condition explicitly ("Ohne title/description liefert das Tool die aktuellen Werte") and prescribes the follow-up workflow for apply_now=true: show the preview to the user and only call deploy_publish with the returned deploy_id after explicit consent. That names the alternative tool and the condition that gates it.

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