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

The description adds a real behavioral fact the annotations do not carry: the candidate receives a Jobiba status email as a side effect. However, 'for most stages' is vague about which stages skip the email, and nothing is said about whether the move is reversible or how to suppress notifications, despite destructiveHint=true and idempotentHint=false.

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, front-loaded with the action and the allowed stages. The phrase 'as in the ATS dashboard' is slightly padding, but overall there is little waste.

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 destructive, non-idempotent mutation with no output schema, an agent still lacks details on reversibility, email exceptions, and what a successful response looks like. The email side-effect disclosure helps but the 'most stages' hedge leaves the key consequence unresolved.

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 100% and the enum is fully documented in the schema, so restating the stage list in the description adds little. The only added meaning is the tie between stages and email sending, which is behavioral rather than parameter syntax.

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 states a specific verb ('Moves') and resource ('an application') and enumerates the six target stages, so the agent can tell this is a stage-transition tool rather than something like update_job_status. It loses a point only because the title says 'applicant' while the description says 'application', a small terminological wobble.

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?

There is no explicit statement of when to use this versus siblings such as shortlist_candidate or message_candidate, and no mention of prerequisites, permissions, or when not to move a stage. Usage is only implied by the verb.

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