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

With no annotations, the description carries the full behavioral burden. It only says the result is a prompt pack with examples; it does not state side effects, permissions, whether the tool is read-only, how the optional query affects execution, or what the response structure is. 'Production-ready' is not behavioral disclosure.

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?

The description is short, but the first sentence spends space on 'production-ready' and an audience segment that is not clearly relevant. The second sentence front-loads the deliverable reasonably, yet the overall structure is less useful than it could be.

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 one-optional-parameter tool with no output schema, the description identifies the deliverable as a prompt pack with examples, which helps. However, it leaves the core behavior ambiguous and does not explain the effect of the query or what the returned pack contains, so it is only minimally complete.

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?

The schema itself has 100% description coverage for the single optional 'query' parameter, so the baseline is 3. The description does not add meaning about how the query scopes the analysis or what happens when it is omitted.

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 names a 'couple talk coach system' and says it delivers a 'copy-paste prompt pack with examples,' so the artifact is somewhat clear. However, it never states what the coach actually does — generate scripts, analyze a conversation, produce exercises — and the 'marketing and operations leaders' audience sits oddly with 'couple talk.' It also does not distinguish this tool from sibling talk-coach or script-generator tools.

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?

No when-to-use or when-not-to-use guidance is provided. It does not mention alternatives such as teen-talk-coach, cross-team-talk-coach, or talk-script-generator, and gives no prerequisites or scenarios; 'run today' is marketing copy, not selection guidance.

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