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

Annotations already declare readOnlyHint/idempotentHint, and the description adds genuinely new context beyond them: it consumes one of the daily render slots and returns only page 1. Quota cost is exactly the kind of constraint an agent needs, though the response format (image type, dimensions) isn't described.

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 short sentences, front-loaded with the core behavior, then the trigger, then the resource cost. Nothing is redundant.

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 output schema exists, and the description does confirm an image is returned and that only page 1 is rendered, plus the quota constraint. Minor gaps remain: image format and what happens when the daily render slots are exhausted.

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 cvId already documents its source (list_my_takemeup_cvs), so the schema does the heavy lifting. The description only implies the singular CV selection and template context, adding no syntax or format detail beyond the 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?

States a precise verb, resource, and output form: show page 1 of a CV as an image in its current template. It also pins the scope with 'the same view as the editor's free preview,' which distinguishes it from data-returning siblings like get_takemeup_cv or export_takemeup_europass.

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 an explicit trigger: after creating or editing a CV, or changing its template, so the user sees the result. It doesn't name an alternative for cases where the agent wants structured data instead (e.g., get_takemeup_cv) or a downloadable file (get_takemeup_download_link), so it stops short of full routing guidance.

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