look-around

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It transparently lists all data returned and implies a read-only operation via 'Get' and 'snapshot'. It does not explicitly state side effects or limitations, but for a zero-parameter situational lookup this is sufficient.

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 two sentences long. The first sentence front-loads the core function and enumerates the data returned; the second sentence gives usage guidance. Every word earns its place, with no unnecessary padding.

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?

Although there is no output schema, the description clearly enumerates all major data categories (position, health/food, held item, inventory summary, time, nearby entities, adjacent blocks), making the return value understandable. It does not specify exact formats or ranges, but this is sufficient for the tool's purpose.

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?

The tool has zero parameters, and the input schema is empty. The description adds no parameter details because none are needed; per the rubric, 0 params receives a baseline of 4.

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 uses a specific verb ('Get') and resource ('full situational snapshot') and enumerates all included data: position, health/food, held item, inventory summary, time of day, nearby entities, and adjacent blocks. This clearly distinguishes it from targeted sibling tools such as get-position, look-at, and list-inventory.

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 explicitly states when to use the tool ('Good first call after spawning or when unsure what's going on'), providing clear context. However, it does not name alternatives or explicitly say when not to use it, so it stops short of a 5.

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