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 and largely fails it. It never says whether the tool computes a diagnosis, what inputs it consumes, or what the caller receives. The claim that it is "delivered as a copy-paste prompt pack with examples" is ambiguous and arguably misleading for a parameterized tool, since it implies a static deliverable rather than an executed diagnostic.

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?

Only two sentences, but a large share of the text is filler: "production-ready", "you can run today", "copy-paste prompt pack with examples". The front-loaded sentence repeats the tool name instead of stating the action, so the structure spends its opening on noise rather than purpose.

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?

With no annotations and no output schema, the description is the only source of behavioral information, and it omits what the diagnostic evaluates, what it returns, and how it differs from the four sibling cvr tools. For a tool whose whole value is a repeatable diagnostic workflow, this leaves the agent unable to call it confidently.

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 parameter and schema description coverage is 100%, so the schema already explains the query as scoping the analysis. The description adds nothing about the parameter, but the baseline of 3 applies when the schema does the documentation work.

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 restates the name ("cvr diag tool system") rather than explaining what a diagnostic is or what it produces. It never distinguishes this tool from the numerous siblings cvr-analyze-tool, cvr-board-tool, cvr-formula-tool, and cvr-tpl-tool, so an agent cannot infer the difference. The remaining sentences are marketing positioning, not purpose.

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?

The only targeting is an audience statement ("for marketing and operations leaders") and a vague "run today" claim. There is no when-to-use condition, no when-not-to-use, and no mention of the sibling tools that cover adjacent cvr tasks. An agent has no basis for choosing this tool over cvr-analyze-tool.

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