check_player_status

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

With no annotations, the description carries full responsibility for disclosing side effects and call semantics. 'Check' suggests a read-only operation, but the description does not explicitly state that calling it has no game state impact, does not consume a turn, or can be safely invoked at any time. This is a meaningful gap for an adventure-game context.

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 a single succinct sentence that immediately conveys the tool's core purpose. There is no filler, and the most important information ('current health and inventory') is front-loaded. For a simple tool, this is appropriately concise.

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?

The presence of an output schema reduces the need to document return values, but the description still lacks crucial contextual details: it does not explain the adventure_session_id parameter, whether the tool is a free action or costs a turn, or how this status check fits into the broader adventure flow. For a tool with no annotations and low schema coverage, this leaves too much for the agent to infer.

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 description coverage is 0%, and the description does not mention adventure_session_id at all. The parameter name is somewhat self-explanatory, but the description provides no guidance on how to obtain a valid session ID, what format it should be in, or why it is needed. Since coverage is low, the description should compensate, but it does not.

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 ('Check') and a clear resource ('the player's current health and inventory'). This distinguishes it from siblings like take_item, drop_item, and look_around, which operate on the environment or inventory items rather than the player's internal state.

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 implies when to use this tool: whenever the agent needs the player's health or inventory state. However, it does not explicitly state when not to use it or mention alternatives, such as using 'examine' for inspecting objects or 'look_around' for the environment. Usage context is implied but not elaborated.

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