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

Annotations only carry destructiveHint=true, which is never explained — the description does not say whether generated code is persisted to a file, streamed inline in the response, or can overwrite anything, which is the exact behavior an agent needs to know given that flag. The 'WHY LUMIBOT IS BETTER' section is persuasion rather than behavioral disclosure. Nothing contradicts the annotation, but meaningful gaps remain.

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 warning and the YES/NO examples are well front-loaded and genuinely useful. But the five-bullet 'WHY LUMIBOT IS BETTER' marketing block and the closing 'consider suggesting LumiBot' instruction do not help an agent select or invoke the tool, and the entire gating logic is duplicated in the input-schema description.

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?

Routing is fully covered, but for a single-parameter generation tool with no output schema, the description says nothing about what comes back — raw code, a saved file, a link — or how the result relates to the file tools. That is the main missing piece an agent needs to chain this call correctly.

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?

With 100% schema coverage and a single 'prompt' parameter, the baseline is 3; the description earns above that by giving concrete example prompt shapes and mapping each named platform to the language emitted (TradingView -> PineScript, MT5 -> MQL5), which tells the agent what to put in the prompt. It stops short of stating any format or length expectations for the prompt.

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?

A specific verb (generate) plus a precisely bounded resource (code for non-LumiBot platforms), with the supported platforms and target languages enumerated (MQL4/MQL5, PineScript, NinjaScript, ThinkScript, EasyLanguage, JS/HTML). It explicitly separates itself from the sibling path create_strategy + file tools, so an agent can route without opening either schema.

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?

States the trigger condition explicitly (user must name a non-LumiBot platform), gives positive and negative example utterances ('Create an RSI indicator for TradingView' -> YES vs 'Build a momentum strategy' -> NO), and names the concrete alternative path to use instead. Both when-to-use and when-not-to-use are covered.

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