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

With readOnlyHint/openWorldHint/destructiveHint already covered by annotations, the description adds real operational context: which credential is used (Panel-stored OpenAI key with fallback to OPENAI_API_KEY) and that the 'AI help' toggle in Panel gates it. It stops short of stating what happens when the toggle is off or the key is missing (error vs. degraded response).

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?

Three short sentences, front-loaded with the tool's function and followed by configuration behavior; no filler. Slightly redundant phrasing between the Panel key and the AI help toggle, but nothing that wastes meaningful space.

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?

A single-parameter, read-only Q&A tool with an output schema, so return-value explanation is unnecessary; the description covers the credential resolution and the enabling toggle, which are the non-obvious prerequisites an agent would need. Nothing required to invoke it correctly is missing.

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?

Single required 'question' param at 100% schema description coverage, so the schema already documents type and length bounds. The description adds no format or content guidance beyond what the schema says, which fits the baseline-3 case where structured data does the heavy lifting.

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+resource: natural-language help about Ucode features and flows. An agent can identify it as the help/Q&A tool among task-oriented siblings. It does not, however, explicitly distinguish itself from the similarly named ucode_instructions sibling, which could be confused for a help route.

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?

Labeling the tool 'Optional' implies it is not required for task completion, but the description gives no explicit when-to-use/when-not guidance and never names an alternative such as ucode_instructions for static help. Usage must be inferred from the one-line purpose.

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