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

No annotations are provided, so the description carries the full behavioral burden. It hints that the deliverable is a prompt pack with examples, but does not say whether it reads or writes data, what the output format actually is, whether permissions are needed, or how it behaves on repeated calls.

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?

It is only two sentences, but much of the text is marketing filler such as 'production-ready' and 'you can run today.' The actual function is not front-loaded, and the key phrase 'copy-paste prompt pack with examples' appears late and remains vague.

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?

Even for a simple one-parameter tool, the description does not explain what 'sph review2' means, what the prompt pack contains, or why an agent should choose it over sph-review-kit. It is not complete enough for confident selection or invocation.

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?

There is a single optional 'query' parameter, and the schema already describes it at 100% coverage as an 'Optional user query to scope the analysis.' The description adds no further meaning about how query scoping works, but with full schema coverage the baseline of 3 is appropriate.

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 names a 'sph review2 kit system' and says it delivers a 'copy-paste prompt pack with examples,' but never states a concrete verb or the specific content produced. With siblings such as sph-review-kit and dozens of other sph-*-kit tools, it gives no basis to distinguish review2 from review or the other kits.

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?

It only frames the audience as 'marketing and operations leaders' and says the workflow can be run 'today.' There is no explicit when-to-use guidance, no prerequisites, and no alternative tool named, so an agent has no routing rule.

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