Track Application

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

No annotations are present, so the description carries the full burden of disclosing the operation. It clearly indicates a mutating, upsert-like behavior, but it doesn't mention the required job_title/company fields, default status, or what happens on invalid application_id. The description is accurate but sparse.

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?

A single, front-loaded sentence that conveys both modes of the tool without waste. It earns maximum points for efficiency.

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?

The output schema and 100% schema coverage carry the parameter detail, so the brief description suffices for the common case. However, it omits guidance on how to obtain an application_id for updates, leaving a minor gap in the overall tool context.

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?

The description itself adds no parameter-specific meaning beyond what's in the schema. With 100% schema description coverage, the parameter semantics are fully handled by the input schema, so this is a baseline 3.

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 clear verb+resource: 'Create a new tracked application, or update an existing one by id.' It distinctively covers the upsert operation, clearly differentiating from siblings like search_jobs, score_resume_match, and list_applications, which have different purposes.

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?

The description gives a clear operational context (create new vs. update by id), but it never explicitly says when to prefer this tool over alternatives or how to obtain an application_id (e.g., via list_applications). No exclusions or alternative references are provided, so the usage is mostly implicit.

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