safari_ready

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

With no annotations, the description carries the full behavioral burden. It usefully discloses the mechanism and side effect (SpringBoard opens the URL, which starts Safari) and the default URL, but omits timeout behavior, failure modes, permission needs, and what happens if Safari is already running.

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?

Two sentences, front-loaded with the purpose and mechanism, with little wasted text. The phrase 'a page the inspector lists' is slightly ambiguous, but the description remains efficiently structured.

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 no annotations, no output schema, and 0% schema description coverage, the description provides enough context to attempt the launch after boot/restore. It still leaves `timeout` undocumented and does not describe failure or return behavior, so it is only adequate rather than complete.

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 0%, so the description must explain both parameters. It explains `url` and its about:blank default, but never mentions `timeout`, leaving the agent without units or behavioral meaning for that 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?

States a specific action: launch Safari at a given URL through SpringBoard, with about:blank as the default. It distinguishes itself from tap/typing flows and mentions inspector-listed pages, but does not explicitly contrast with siblings such as open_url or navigate.

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?

Gives a clear timing condition: call after the VM has booted or a snapshot is restored. However, it does not state when not to use it or how it differs from open_url, navigate, or reload, leaving alternatives to inference.

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