render_page

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

With no annotations provided, the description must bear the full burden of behavioral disclosure. It fails to state that the tool writes a file to output_path, whether it overwrites existing files, requires an existing template, or has any other side effects. The term 'assemble' is too abstract to convey the concrete behavior.

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 a single sentence, but its brevity is the result of under-specification rather than effective conciseness. It omits critical information about the tool's inputs, outputs, and behavior, making it more a placeholder than a useful definition.

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 6 parameters, nested objects, no output schema, and no annotations, this description is severely incomplete. It does not explain the assembly workflow, return value, prerequisites, or how the parameters interact. The schema provides some parameter documentation, but the description adds no contextual guidance to make the tool usable.

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 description adds no parameter-specific meaning beyond the schema's existing descriptions. Schema coverage is 67% (template, sections, output_path, entity_annotations have descriptions), but budget and options remain undocumented in both the schema and description. The phrase 'structured components' only vaguely hints at the sections parameter without clarifying its structure or required fields.

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 'Assemble page from structured components' provides a verb ('assemble') and a resource ('page'), but is vague about what 'assemble' produces (an HTML file) and how it relates to the structured components. It does not distinguish this tool from siblings like write_html_file or patch_html, which also deal with building or editing HTML pages.

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 information is given about when to use render_page versus alternative tools. The sibling list includes many related tools (write_html_file, patch_html, insert_section, etc.), but the description offers no context, exclusions, or selection criteria, leaving the agent without usage guidance.

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