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

Beyond the annotations (readOnly, idempotent, non-destructive), the description discloses that the call is free, that results are tool ids with short descriptions, and that prices come back as {usd, idr} billed against a prepaid balance. That cost and return-shape context is exactly what annotations cannot express and what an agent needs before chaining to run_tool.

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?

Front-loaded with the action and a strong "Start here" directive, followed by return shape and the flow. The long parenthetical catalog enumeration is the only padding, though it does serve retrieval matching, so it mostly earns its place.

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?

There is no output schema, so the description takes on the return-value burden and does so concretely (ids, short descriptions, {usd, idr} price, prepaid billing). Combined with the explicit three-step flow, an agent has everything needed to call this correctly and know what comes next.

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 coverage is 100%, and the schema's own query description already carries the worked examples, so the description's "describe the job in plain words" adds only framing rather than new meaning. The limit parameter and its 1-20 bound are left entirely to the schema.

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 (search) and resource (the 1ToolRing third-party tool catalog), then enumerates the domains covered so an agent can match a user job to it. It is clearly distinguished from siblings inspect_tool and run_tool, which are named later in the flow.

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?

"Start here for any job" is an explicit entry-point directive, and the stated flow (discover_tools -> inspect_tool -> run_tool) tells the agent exactly when to hand off to each sibling. No alternative interpretation is left open.

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