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

With no annotations, the description carries the full behavioral burden. It does hint that the result is "a copy-paste prompt pack with examples", which is a genuinely useful output-format clue, but it says nothing about what the tool does with the optional query, whether it mutates anything, or how large/structured the deliverables are.

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 both are sales copy rather than functional description; the front-loaded sentence contains zero actionable information about the tool's operation. Every clause would need replacing, not trimming.

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?

For a tool in a dense family of copywriting siblings with no annotations and no output schema, the description should at minimum state the format produced and how it differs from `moments-copywriter`. It gives only a vague "prompt pack with examples" and leaves the agent guessing.

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 coverage is 100% and the single `query` parameter is already documented in the schema as an optional scoping input. The description adds no further meaning about its format or effect, so 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 restates the name ("moments copy system") and pads it with marketing language ("production-ready", "repeatable workflow") rather than stating a verb and a concrete output. It never distinguishes itself from the near-identical sibling `moments-copywriter`, so an agent cannot tell the two apart from the text alone.

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 signal is an audience ("marketing and operations leaders"), which does not tell an agent when to pick this over `moments-copywriter`, `viral-copywriter`, or `xhs-viral-copywriter`. There are no preconditions, exclusions, or alternative-routing guidance.

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