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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the agent knows this is a safe, local, non-mutating read. The description adds nothing behavioral beyond that — no note on caching, freshness, auth, or error conditions. With the safety profile already covered by annotations, a 3 is appropriate.

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?

A single sentence that front-loads the verb and resource, then lists the returned sections. Every clause carries information and there is no filler.

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 compensates by enumerating the sections the CV contains, which tells the agent what it will receive. Combined with annotations covering the safety profile and a zero-parameter schema, this is nearly complete; only the boundary with the sibling portfolio tool is left unstated.

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 tool takes zero parameters, so there is nothing for the description to disambiguate and the baseline of 4 applies. No parameter-related information is missing or misleading.

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 specific verb and resource ("Get Bahdan Hal's full curriculum vitae") and enumerates the content sections returned: experience, skill stack, education, and languages. This makes the tool's scope clear. It stops short of a 5 because it does not draw the boundary against the sibling get_portfolio_overview, which could plausibly overlap with CV content (skills, experience).

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?

Usage is only implied: an agent can infer this is the right tool when a user asks about the person's background, experience, or skills. There is no explicit statement of when to prefer this over get_portfolio_overview or get_services_and_pricing, and no exclusions or prerequisites are given.

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