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

With no annotations provided, the description carries the full burden, and it does well: it prominently discloses the educational-only nature, states that it screens for urgent red-flag signs, and explains that redFlags=true forces urgent-care routing. It does not delve into every behavioral consequence, but the key safety-related behavior is transparently communicated.

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 three tightly written sentences with no wasted words: a safety disclaimer, a clear summary of what the tool does, and a targeted instruction for the most important parameter. It is front-loaded and every sentence earns its place.

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 7-parameter optional-input tool with no output schema and no annotations, the description covers the essential context: purpose, scope, safety caveat, red-flag behavior, and output type. It could be slightly more complete by describing what the generated 'information brief' contains or how non-red-flag cases are routed, but overall it is sufficient for correct invocation.

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 100%, so the schema already documents all seven parameters in detail. The description adds useful emphasis on redFlags behavior, but that meaning largely duplicates the schema's own description of redFlags. No significant additional parameter semantics are provided 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?

The description clearly states the tool's specific function: it organizes lower-back and leg symptoms, screens for red-flag warning signs, and returns a plain-language next-step information brief for an Oklahoma City patient. It is more specific than a tautology and clearly distinct from generic education-article tools, though it does not explicitly name or differentiate itself from siblings like assess_next_step.

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 gives clear context for use: it is for reported lower-back and leg symptoms and for an Oklahoma City patient. It also provides an explicit conditional usage instruction for redFlags=true to force urgent-care routing. It does not explicitly state when not to use the tool or name alternative sibling tools, but the intended trigger context is reasonably clear.

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