get_active_chart_recommendation

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

Annotations already declare readOnly=true, openWorld=true, and destructive=false, so safety is covered. The description adds valuable behavioral context beyond annotations: it queries Chrome/Edge remote debugging on port 9222 and reads the active symbol, exchange, and timeframe. It does not cover failure modes or permissions, but the operational prerequisite is useful.

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 two tight sentences: the first front-loads the purpose, and the second explains the mechanism. Every sentence adds useful information without repetition or filler.

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 zero-parameter tool with no output schema and complex browser integration, the description is nearly complete. It names the dependency on port 9222 and describes what happens internally, though it could say more about the recommendation output format.

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?

There are zero parameters, so the baseline is 4 per the rubric. The description does not need to document parameter syntax, and it correctly avoids inventing or implying inputs.

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 states a specific verb and resource: detecting the active TradingView chart in a browser and returning a live trade recommendation. It clearly distinguishes itself from generic analysis siblings through the browser-chart context, but it does not explicitly name or contrast with any sibling tool.

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?

Usage is implied by the browser-chart context: use this when an active TradingView chart is open and a recommendation is wanted. However, there is no explicit when-to-use statement, no when-not guidance, and no named alternatives among the many analysis and backtest siblings.

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