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

Annotations already carry the safety profile (readOnlyHint=true, idempotentHint=true, destructiveHint=false); the description adds value beyond that by explaining what the tool produces (evidence, flags, next actions), its role as a first-call diagnostic, and the ordered journey it evaluates. 'It reads only' slightly restates the annotation but is harmless reinforcement. Without an output schema, the description does real work in setting expectations.

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 earn their place: the first packs the purpose, output contents, and the journey stages; the second delivers usage directives. The arrow-chain construction is ornate and slightly dense, but nothing is wasted and the core purpose is front-loaded before the usage guidance.

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, read-only orchestrator with no output schema, the description covers the essentials: what it evaluates, what the output contains, and how to act on it. The return shape is described conceptually rather than precisely (no JSON structure), but 'next actions each named by the tool that does it' is enough for an agent to consume the result and route to siblings.

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?

The tool has zero parameters and the schema is trivially complete at 100% coverage, so there is nothing the description must document. The baseline of 4 for zero-param tools applies; the description appropriately devotes no space to parameters.

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+resource ('Read the creator's account and place it on the path...') with a concrete deliverable: evidence, flags, and next actions each named by the tool that does it. The stage chain (profile → page → brands → collections → grow) makes the tool's scope unmistakable and distinguishes it from the many CRUD siblings by framing it as the orchestrator that points to them.

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?

Gives explicit triggers: 'Call this FIRST on a new or quiet account, and whenever the creator asks what to do next; act on its output rather than guessing.' This is strong when-to-use guidance that also prescribes follow-through behavior. It stops short of a 5 because it never names an alternative tool or states when NOT to use it (e.g., a targeted question like link performance would bypass this tool).

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