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

With no annotations, the description fully carries the burden. It explicitly states this tool does not perform the requested action, is a stub, and returns a coming_soon response. It also provides safety advice (no secrets). This is high transparency, though the exact response structure is not detailed.

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?

The description is two sentences, efficiently front-loading the key message ('Coming soon') and then disclosing behavioral traits and safety. No unnecessary 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?

Given the tool is a stub with 4 optional parameters and no output schema, the description is complete. It explains what the tool does (records demand), what it doesn't do (perform action), and includes a critical safety warning. No gaps for its limited functionality.

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%, so baseline is 3. The description adds no additional parameter-level details beyond what the schema provides. It offers a general warning but no parameter-specific semantics.

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?

Description clearly states it is a 'Coming soon' stub that records demand and returns a coming_soon response. It differentiates itself from siblings by explicitly saying it does not perform the action yet, making its purpose unmistakable.

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?

Description gives context that this is a PMF stub and warns not to send secrets, but does not explicitly state when to use it versus other tools like hostodo_list_payment_methods. Usage is implied but not formally guided.

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