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

Annotations declare readOnlyHint=false and destructiveHint=false, so the safety profile is partly covered. The description adds that calls are forwarded to an external gateway, but does not disclose that downstream external tools may have side effects, auth requirements, or error propagation behavior. It adds some context without contradicting the 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?

Three sentences, front-loaded with the core action and scoping, followed by use-case examples and a reference link. No wasted text, though the API URL is the least essential element.

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 gateway/proxy tool with a rich 4-param schema (including a method enum and timeout) and no output schema, the description covers purpose and routing adequately. It stops short of describing response shape or failure modes, which an agent invoking arbitrary external tools would benefit from knowing.

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% and each parameter (method enum, arguments, tool_name, timeout_seconds with default) is documented in the schema. The description adds no parameter-level meaning beyond the schema, so the baseline of 3 applies.

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 and resource ('Forward a tool call to the organization's configured executor.sh MCP gateway') and clarifies the class of action via examples (GitHub, Slack, sandbox functions). No sibling in the list does proxy/gateway calls, so it is easy to distinguish from task/project management tools.

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?

Explicitly says when to use it: to reach tools hosted outside Tango. It gives concrete example targets, but offers no when-not guidance (e.g., what to do if the tool is already integrated natively via list_integrations/read_integration).

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