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 return is a 'copy-paste prompt pack with examples', but never states whether the tool generates content, returns static template text, or is read-only, nor how the optional query changes the output. Marketing adjectives like 'production-ready' and 'repeatable' convey no operational behavior.

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 short and front-loaded, but the two sentences are promotional filler ('production-ready', 'pro system', 'run today') rather than functional detail. Almost nothing would be lost by cutting the adjectives, but almost nothing useful is gained by keeping them.

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 must explain behavior and routing on its own, and it does not. For a tool sitting among dozens of brand/annual-planning siblings, an agent cannot tell what it produces or when to invoke it, so the definition is incomplete for its context.

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% for the single optional 'query' parameter, so the schema already explains it. The description adds no meaning about how a query scopes the plan, but with one well-documented optional parameter the baseline of 3 applies.

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 says it is a 'brand year plan pro system' and that the deliverable is a 'copy-paste prompt pack with examples', which loosely indicates the resource and output form. However, the verb is a soft marketing 'Get' rather than a specific action, and the phrase largely echoes the tool name. It never distinguishes itself from near-identical siblings such as annual-brand-marketing-pro, year-plan-generator, or brand-strategy-planner.

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 scoping is an audience statement ('for marketing and operations leaders'), which is not a use condition. There is no statement of when to choose this over the many sibling planning tools, no prerequisites, and no exclusions. An agent would have to guess based on the name alone.

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