add_nav_button

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

With no annotations, the description adds some context like 'Structure matched to Power BI ground truth' and clarifies targetPage semantics. However, it does not disclose validation behavior, side effects, or how the button is integrated into the page, leaving key behavioral aspects unexplained.

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?

Four concise sentences with no filler; each adds value—purpose, ground truth fidelity, composition guidance, and targetPage clarification. Well front-loaded.

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 10-parameter tool with no annotations and no output schema, this description is too thin. The crucial distinction between pageName (placement page) and targetPage (destination) is not explicitly explained, and positional/color parameters remain ambiguous, making it hard for an AI agent to invoke correctly.

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 covers only 40% of parameters, leaving six undocumented. The description only restates targetPage's meaning already in the schema and offers no explanation for pageName, reportSessionId, x/y, width/height, or color parameters, failing to compensate for the low coverage.

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?

Clearly states 'Add a navigation button that jumps to another page (multi-page navigation)' with a specific verb and resource. Distinguishes from siblings like add_button by emphasizing the navigation purpose and mentioning 'Compose several into a nav bar/sidebar'.

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?

Provides clear usage context by noting 'Compose several into a nav bar/sidebar', indicating typical scenarios. However, it does not explicitly name alternatives or exclusions, so it falls short of a 5.

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