Open IELTS speaking dashboard

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

Annotations provide readOnlyHint=false, openWorldHint=false, and destructiveHint=false, which give some baseline. The description adds that this opens a 'learner's private local' dashboard, conveying a personal-scope and UI-navigation behavior. However, it doesn't disclose what 'open' entails (e.g., whether it navigates the learner's browser, launches a local file, or returns a view) or any side effects, leaving behavioral clarity incomplete.

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?

One clean sentence that states the action, target, and purpose. It is front-loaded and free of filler. A minor deduction because 'with buttons' is slightly redundant detail, but the overall structure is tight and effective.

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 this is a zero-parameter, navigation-style tool with an output schema present, the description is adequately complete. It explains the purpose and scope. It could be enhanced by clarifying what happens after opening (what the output represents) and its relationship to get_dashboard_data, but the presence of an output schema reduces that burden.

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% (nothing to document). Per the rubric, 0 params earns a baseline of 4. The description doesn't need to add parameter semantics since there are none, and it correctly conveys the tool requires no inputs.

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 states a specific verb ('Open') and resource ('learner's private local dashboard') with a clear purpose ('to choose a practice route with buttons'). It distinguishes itself from siblings like get_dashboard_data, which likely returns data rather than opening a UI. Slight ambiguity about what 'open' means in an MCP context (navigate vs. launch) prevents a 5.

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 this is a navigation/action tool to reach the dashboard for choosing practice routes, contrasting with get_dashboard_data. However, it does not explicitly state when to use this versus get_dashboard_data or when not to use it. There is also no mention of prerequisites like whether the workspace must be initialized first (sibling initialize_ielts_workspace suggests this may be needed).

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