Connect GTFS transit feed

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

Annotations already flag readOnly=false and destructiveHint=false, consistent with 'Create'. Description adds that it builds maps and predictions but doesn't disclose side effects like external connections, file/component modifications, or requirements for the adapter URL. It adds modest context beyond annotations.

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?

Single sentence, clear verb, front-loaded. The list of scaffold components is compact but comprehensive enough for an overview. No redundant words.

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 creation tool with 9 parameters and no output schema, the description is too sparse. It omits how feed_mode affects the scaffold, whether adapter_url must point to a live service, what public-data notes include, and how the scaffold integrates with the parent_path. Ambiguity remains about the scaffold's runtime behavior.

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 only 22%, with 7 of 9 parameters undocumented in schema. The description mentions route maps, stop maps, arrival predictions, and adapter source, which loosely correspond to route_count, stop_count, prediction_count, and adapter_url, but does not explain feed_mode, active, agency_label, or parent_path meanings. Insufficiently compensates for low schema coverage.

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?

Clearly states it creates a GTFS transit scaffold with enumerated deliverables (route maps, stop maps, arrival predictions, adapter source, public-data notes). Differentiates from generic create_* siblings by naming specific transit domain and scaffold scope.

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?

No explicit when-to-use or alternatives. The description implies usage for generating a GTFS feed scaffold, but does not specify when to choose this over other connect_* tools or any prerequisites.

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