observe_actor

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

No annotations are provided, so the description carries the full behavioral burden. 'Bounded state' hints at a capped payload but never says what the cap is, what happens if no dedicated player is configured, whether this is a read-only polling call, or any rate/cost characteristics.

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?

A single front-loaded sentence with no filler, which is appropriate for a zero-parameter tool. It is not padded, though it is arguably too terse to front-load anything beyond the verb and resource.

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?

An output schema exists, so return values need not be explained, and there are no parameters to cover. That said, with zero annotations the description leaves key behavioral questions (bounded how, unavailable-actor behavior, read-only nature) unanswered.

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?

Zero parameters, so the schema offers nothing to document; baseline is 4. The phrase 'configured dedicated player' does add the useful notion that the target is set elsewhere rather than passed in, which is meaningful given the empty schema.

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 verb ('Return') and a resource ('state for the configured dedicated player'), which loosely separates it from observe_local. But 'bounded state' is undefined jargon — an agent cannot tell what state fields (position, health, inventory, surroundings) are returned, so the purpose stays vague rather than specific.

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?

No when-to-use guidance, no when-not-to-use, and no mention of the sibling observe_local despite the near-identical name. The reader must infer the local-vs-remote distinction themselves.

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