Project overview

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

With no annotations, the description carries the full behavioral burden. 'Summarize' implies a non-mutating read and the enumerated scope tells the agent what it covers, but it says nothing about whether this is expensive, whether it requires the project to be configured/loaded, or how it behaves on an empty or invalid project.

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 the verb first and the enumerated contents following. Every clause carries information; there is no filler.

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?

For a zero-parameter, low-complexity read tool with no output schema, the description's enumeration of returned categories (maps, tilesets, database tables, switch/variable names, engine version) effectively serves as the return-value contract. Only the absence of any usage context keeps it from being fully 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?

The tool takes zero parameters, so there is nothing for the description to disambiguate. The baseline for a parameterless tool applies.

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 verb ('Summarize') and resource ('the configured RPG Maker MZ project') and enumerates the exact contents of the summary: maps, tilesets, database tables, switch/variable names, and engine version. This distinguishes it from narrower siblings like list_maps or read_database, though it never names those siblings explicitly.

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?

There is no explicit when-to-use guidance, no statement of prerequisites, and no routing to alternatives such as list_maps or read_database for targeted queries. The orientation use case is only implied by the word 'Summarize'.

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