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

The annotations already declare readOnlyHint, idempotentHint, non-destructive, and closed-world behavior. The description adds useful context by saying it returns full CV content and that changes must go through save_takemeup_cv, though it omits any notes on authorization or response formatting beyond the section list.

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 two compact sentences and front-loads the read purpose before listing returned sections. Every part earns its place by clarifying scope, usage timing, and the save pathway.

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 low-complexity read tool with full schema coverage and rich annotations, the description gives complete-enough context: what it reads, which CV sections are returned, when to use it, and how to persist changes. No output schema exists, but the section enumeration adequately communicates what comes back.

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%, with cvId documented as coming from list_my_takemeup_cvs and locale documented with its default. The description does not add parameter-specific meaning beyond what the schema already provides, so the baseline score 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 uses the specific verb "Read" with the specific resource "one of the user's CVs" and enumerates exactly what content is returned. It is clearly distinguishable from sibling tools like list_my_takemeup_cvs or get_takemeup_cv_preview.

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?

It gives explicit usage context: use before editing, tailoring, or reviewing a CV, and directs saving changes to save_takemeup_cv. It does not explicitly exclude preview or listing tools, so it stops short of fully routing between all alternatives.

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