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

Annotations already declare readOnly=false, destructive=false, openWorld=false, so the mutation profile is covered. The description adds value beyond that by disclosing the return values (id + editor link), the optional template parameter's behavioral effect, and the free-cost trait. It does not restate or contradict any annotation.

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?

Two tightly-packed sentences with no filler: the core action and return value come first, followed by the usage context and next-step tool. Every clause carries information the agent needs.

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 simple zero-required-parameter creation tool with no output schema, the description covers the action, return values, cost, and the follow-up save step, which is sufficient to invoke it correctly. The only gap is the lack of explicit routing against the sibling creation tools.

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%, so both locale and templateId are already documented with examples, establishing the baseline of 3. The description only hints at the template option ('optionally with a template') without adding syntax or default behavior beyond what the schema says.

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?

States a specific verb and resource ('Create a new, empty CV') and adds the return payload (id and editor link), so the agent knows exactly what it gets back. It does not explicitly distinguish itself from close siblings like create_takemeup_cv_from_role or create_takemeup_one_click_cv, leaving a small ambiguity for an agent choosing between creation variants.

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?

Gives a clear situational trigger ('start a CV from scratch or from a file the user attached') and names the natural follow-up tool save_takemeup_cv, plus a 'Free' cost signal. It stops short of excluding the sibling creation tools, so the agent must infer when to prefer create_takemeup_cv_from_role instead.

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