read_game_state

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

With no annotations, the description carries the burden: it discloses the data source (game RAM) and that output is a compact text report, which implies a safe read. It does not state that the operation is non-mutating, whether the game must be running, or what happens if RAM is unavailable.

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 a dense field list; nothing is padded and the source qualifier ('straight from game RAM') comes before the payload enumeration.

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 the field list is a useful preview rather than a substitute. The only gap is the lack of any precondition (e.g. a game must be running), which matters for a RAM-reading tool.

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 there is nothing to document and the baseline of 4 applies. The description correctly spends its words on output content instead.

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 resource (game state) and enumerates exactly what it returns: location, party, HP, money, badges, bag, battle status. 'Straight from game RAM' implicitly separates it from the visual get_screenshot and the raw read_memory, though neither sibling is named.

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 phrase 'compact text report straight from game RAM' implies the use case (cheap textual snapshot rather than a screenshot or raw memory dump), but there is no explicit when-to-use or when-not-to-use statement and no sibling is referenced.

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