Create Capacities URL object from Markdown

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

Annotations already indicate this is not read-only, but the description adds useful behavioral context: conversion is lossy for exact underline styling, toggle details, Grid layout, and HTML background colors, and lossReport should be inspected. This goes beyond the structured annotation data.

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?

Two sentences, front-loaded with the core purpose, immediately followed by the alternative and a critical caveat. No wasted words or redundancy.

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?

An output schema exists, so return values are covered structurally. The description covers purpose, distinguishes from the preferred alternative, and warns about lossy conversion. It could have explicitly stated when this tool is the best choice, but it is sufficiently complete for an agent.

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 input schema has 100% description coverage with detailed parameter docs. The tool description only reiterates 'URL and Markdown' without adding new semantics beyond the schema, so baseline 3 is appropriate.

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 clearly states the tool creates a Capacities web-resource object from a URL and Markdown notes, using the specific verb 'create' and naming the resource. It also distinguishes itself from the sibling create_object_from_url by calling that the 'preferred structural-block workflow', making its own purpose clear.

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 explicitly mentions an alternative (create_object_from_url) and characterizes this tool differently ('explicit Markdown' vs structural-block). It also warns that conversion is lossy and advises inspecting lossReport, which helps the agent decide whether to use this approach.

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