magento_trace_flow

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

No annotations provided, so the description carries full burden. It discloses chaining multiple searches to map controller to plugins to observers to templates, and mentions depth and entryType controls. Good disclosure of behavior, though no mention of side effects or limitations.

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 with no wasted words. First sentence immediately states purpose and examples. Second sentence explains what it does (chains searches) and use case. Front-loaded and efficient.

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?

Given the tool's complexity and lack of output schema, the description adequately explains what it traces and how. It covers entry types and depth. Could mention return format (a trace map) but not critical. Good overall.

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% with clear parameter descriptions. The description adds marginal value beyond schema (e.g., 'faster' vs 'more complete' for depth), but this is baseline 3 as schema already documents parameters well.

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 uses a specific verb 'trace' and resource 'Magento execution flow', listing multiple entry point types (route, API, GraphQL, event, cron). This clearly distinguishes it from sibling tools like magento_search or magento_find_class.

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?

It explicitly states 'Use this to understand how a request is processed end-to-end.' While it doesn't list when-not-to-use or alternatives, the sibling context implies specialized tools exist for sub-steps, making usage clear.

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