application_set_status

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

With no annotations, the description carries full behavioral burden and does not meet it. It never says whether this creates an application record when none exists for the job_id, whether a prior status is overwritten, whether notes are merged or replaced, or what the response looks like. The one real disclosure is the closed set of valid statuses, which is genuinely useful but far short of a mutation tool's needs.

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 fragments with no filler; the enum list is front-loaded right after the purpose. "Track progress" is thin but does not waste space, so the length is appropriate for the information conveyed.

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 three-parameter mutation with no annotations and no output schema, the definition is too thin on side effects and does not say what happens if the application does not exist or what status transitions are permitted. The enum enumeration keeps it from being inadequate, but key behavioral gaps remain.

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 0% and status is declared as a bare string with no enum, so the description's eight status values are the only documentation of the most important parameter and prevent invalid input. However, job_id and notes receive no explanation at all, and the partial coverage only partly offsets the 0% baseline.

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 name supplies the verb and resource (set an application's status), but the description itself only says "Track progress," which is vague until the enumerated status values arrive. The status list does make the effect concrete enough to distinguish it from applications_list, though the description alone never states plainly that it records an application's stage.

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?

No when-to-use guidance is given and no sibling is named. The agent is left to infer that this is the write counterpart to applications_list and that it should be called after applying, interviewing, etc., rather than being told so.

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