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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds the non-obvious fact that per-action parameter schemas must be discovered through a help action, but says nothing about error behavior, empty states, or what an unconfigured setup returns.

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 short sentences with the resource scope front-loaded and the action list immediately after; no filler. The opening clause ("Where first-time setup stands") is slightly awkwardly phrased, but nothing is wasted.

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 four-action dispatcher with no output schema, the description identifies what each action reads but never characterizes the shape or content of those returns, nor the relationship to run_setup. It is adequate to call the tool but leaves the agent guessing about results.

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 description coverage is 67%: action (enum) and ingestion_id (with pattern and provenance from run_setup import_resume) are documented in the schema, while params is loosely specified. The description repeats the action names already present in the enum and points to the help action for field discovery, which is a modest addition rather than new semantic detail.

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 the resource (first-time setup) and its readable facets — setup status, résumé import progress, and job previews — then enumerates the four read actions, so an agent knows exactly what it can retrieve. It doesn't explicitly contrast itself with the sibling run_setup, but the read-oriented framing makes the division reasonably inferable.

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 explains the tool's own dispatch mechanic — call action "help" to discover each action's fields — which is a useful invocation guideline. However, it gives no when-to-use/when-not guidance and never names run_setup as the mutation counterpart, so the choice between reading and running setup is left to inference.

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