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

With no annotations supplied, the description carries the full disclosure burden and fails it. It says nothing about what the tool produces, whether it mutates anything, what permissions it needs, or what the caller should expect back — only that it 'saves hours' and requires 'no setup'.

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, but both sentences are marketing copy ('Save hours every week', 'battle-tested prompt and operating playbook') that consume the entire budget without stating the operation. The most prominent position is wasted on a hook rather than on what the tool does.

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?

No annotations, no output schema, and a description that conveys no operational information. In a tool family with nine near-identical weekly-* variants, an agent cannot determine from this text what the tool consumes, produces, or when to prefer it — the definition is effectively unusable for selection.

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 one optional parameter ('query') and schema description coverage is 100%, so the schema already explains its meaning. The description adds no additional semantics such as what the query should contain or how it scopes the polish output, which is the baseline 3 for a well-covered single-param schema.

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 never states a verb or the resource being operated on. "This weekly polish tool toolkit gives you a battle-tested prompt and operating playbook" restates the name and sells a product rather than telling an agent what the call does. Only the implicit domain hint ("restaurant/brand growth") distinguishes it at all from siblings like weekly-write-tool or weekly-summary-tool, and that hint is about marketing, not function.

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?

There is no when-to-use guidance, no when-not-to-use, and no named alternative among the many weekly-* siblings (weekly-audit-tool, weekly-check-tool, weekly-rewrite-tool, etc.). "No setup, works in any LLM chatbot" is a product claim, not invocation guidance.

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