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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds real context beyond that: this tool returns a state document covering profile, recurring answers, search preferences and applications, plus the rules and browser-setup instructions. That tells an agent what it gets back and why it is a prerequisite, though it says nothing about size, pagination, or freshness of the guidance.

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?

It is a single dense sentence with a colon-delimited content list, followed by a one-line call to action, so the key point (read before applying) is front-loaded. Every clause maps to a real section of the guide, though the sentence is long enough that it reads as a run-on.

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 documentation tool with no output schema and only optional, fully-described parameters, the description is complete enough: it enumerates what the guide contains and when to read it. It could say more about whether the guide is static or versioned, but nothing essential to calling it correctly is missing.

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?

Both parameters (client, context) have complete schema descriptions, so the schema carries the semantics and the description adds nothing about them. With 100% coverage and zero required parameters, the baseline 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 names the specific resource (a procedure/guide for applying on someone's behalf) and enumerates its contents: the state document to keep, the rules, how an application is sent via the agent's own browser, and how to set one up when none exists. It also links it to the siblings it governs (find_jobs, job_questions), so an agent can distinguish it from those tools. The colon-heavy enumeration makes it slightly listy, but the purpose is unambiguous.

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?

"Read it once before applying" gives explicit sequencing guidance relative to the apply workflow and the named sibling tools. It does not spell out when not to call it or what happens if skipped, so it falls short of a full when/when-not treatment.

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