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

No annotations are supplied, so the description carries the entire behavioral burden, and it discloses nothing: not whether the tool is read-only or mutating, not whether it needs input content or credentials, not what "includes the complete prompt, usage guide, and edge-case handling" means operationally. The phrase "prompt pack" hints at a returned artifact but is left unexplained, leaving the agent unable to predict the effect of calling it.

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?

Three sentences, none of which convey operational information — "helps restaurant and brand teams produce professional results in minutes" is pure sales copy. The text is short but under-specified rather than concise, and no actionable detail is front-loaded.

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?

The tool is structurally simple (one optional parameter, no output schema, no nested objects), so the bar is low, but the description still fails it: it never says what input it consumes, what artifact it produces, or what "rewrite" means for expenses. The prompt-pack framing occupies the space where functional detail should be.

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% and there is a single optional `query` parameter already documented in the schema, so the baseline is 3. The description adds no meaning about how `query` scopes the rewrite (source text? brand context? expense category?), but the schema itself is sufficient for correct invocation.

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 tool name ("expense rewrite tool prompt pack") and wraps it in marketing copy — "Turn expertise into output" and "produce professional results in minutes" — without saying what actually gets rewritten (receipts, expense reports, policy text?) or what the tool returns. It does gesture at an audience (restaurant and brand teams) but never states a concrete verb+resource, so an agent cannot distinguish it from the many adjacent expense siblings.

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 and no mention of any alternative. The sibling list contains expense-audit-tool, expense-check-tool, expense-polish-tool, expense-write-tool, expense-summary-tool and more, and the description gives no basis for choosing this one over any of them. The only implicit signal is the target audience phrase, which is not a usage condition.

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