open_study_app

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

With no annotations provided, the description must disclose behavioral traits. It only states 'Local study app tool', offering no information about side effects, prerequisites, or whether the tool is destructive or read-only.

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 extremely short but lacks substantive content. It is under-specified rather than concise, failing to provide necessary information for an agent to use the tool correctly.

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?

Given the presence of several sibling tools (e.g., 'start_study_app', 'get_study_app_status'), the description is grossly incomplete. It does not explain how this tool relates to others or what the 'open' action entails.

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 schema coverage is 100%. While the description adds no meaning beyond the empty schema, the lack of parameters makes this dimension less critical. A score of 3 reflects minimal adequacy.

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 'Local study app tool' is vague and does not specify what action the tool performs. It fails to state whether it opens, launches, or initializes the app, and does not distinguish it from sibling tools like 'start_study_app'.

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 guidance is provided on when to use this tool versus alternatives such as 'start_study_app', 'stop_study_app', or 'get_study_app_status'. The description gives no context for appropriate usage.

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