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

Annotations already cover readOnly/idempotent/non-destructive/non-open-world, so the bar is lower, but the description adds genuinely useful context beyond them: 'nothing is saved', which resolves the ambiguity that actions named create_from_profile and export might persist data. It still omits any auth or rate-limit detail.

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 tight sentences with no filler; the resource scope is front-loaded and the action enumeration plus help pointer follow. The only blemish is the fragmentary, slightly awkward opening clause, which reads like a list rather than a sentence.

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?

With no output schema, the description should convey return behavior, and it only sketches it (résumés, a master résumé, a PDF/Word file) without describing format or structure. The help action offloads parameter discovery, but an agent still lacks return-value detail for a multi-action tool.

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 50% and the params object (additionalProperties=true) is only described by a pointer to the help action. The description restates the action list already present in the enum and offers the help mechanism for field discovery, so it does not compensate for the undocumented per-action fields.

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 enumerates the resources exposed (saved résumés, a profile-built master résumé, PDF/Word export) and the three read actions, and the title supplies the verb 'Read'. It implicitly contrasts with the sibling manage_resume_studio, but the opening is a verbless noun-phrase fragment rather than a crisp statement of purpose.

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 a discovery instruction ('Call with action "help" for each action's fields') and the 'nothing is saved' caveat, which is useful context. However, it never states when to use this read tool versus the manage_resume_studio sibling, leaving the selection to inference from the name.

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