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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered. The description still adds a meaningful nuance: 'This action cannot be undone from here,' signaling irreversibility with a hint that recovery may exist elsewhere. It does not, however, mention permission requirements or what happens to the application record afterward.

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 compact sentences with the action and identifier front-loaded and the irreversibility caveat second. No filler, no repetition of the title.

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 an output schema present, return values need not be explained, and the tool's one-parameter surface is simple. The description covers what it does and its irreversibility; it could optionally surface the isWithdrawable precondition rather than leaving it buried in the schema.

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% and the single parameter is fully documented, including the isWithdrawable eligibility constraint. The description's 'by its application id' adds nothing beyond the schema, so the baseline 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?

States a specific verb (withdraw) and resource (submitted job application) plus the identifying key (application id). It is the only mutation tool among siblings, so an agent can distinguish it immediately from read-oriented siblings like get_my_applications.

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 implied by 'one of your submitted job applications' and the id-based invocation, but no explicit when-to-use, when-not, or alternative is given. The precondition that only isWithdrawable applications can be withdrawn lives in the schema, not the description, so the description itself adds no routing guidance.

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