analyze_headings

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

No annotations are provided, so the description carries the full behavioral burden. It only repeats the tool's analytical purpose and says nothing about whether it fetches the page, requires authentication, handles errors, or what it returns. Implicitly read-only, but no explicit behavioral disclosure.

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 short, front-loaded sentence with no filler. It is efficiently structured and easy to parse, though its extreme brevity is inseparable from the other gaps noted above. A 4 rather than 5 because there is no additional structural aid.

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 tool with no annotations and no output schema, the description should convey enough context to invoke and interpret it. It omits usage context, sibling differentiation, and return expectations, leaving an agent with little beyond the bare purpose. Incomplete for a simple but ambiguous member of a large analyze_* family.

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 description coverage is 0%, and the single required url parameter gets no description in the text. 'of a webpage' faintly implies the URL points to a webpage, but format, requiredness, and examples are left to the schema's minimal uri format. Adds almost nothing beyond the schema.

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 ('Analyze') and resource ('heading structure of a webpage'), so the function is clear. However, it does not differentiate itself from the many sibling analyze_* tools (e.g., analyze_content, analyze_accessibility), which also operate on a webpage. A clear 4, not 5, because sibling differentiation is absent.

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 when-to-use or when-not-to-use guidance. With 27 sibling analyze_* tools, an agent gets no help deciding between this and analyze_content or analyze_accessibility. Absence of alternatives or context earns a 2.

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