Update application tracking

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does reveal that status changes are timestamped and that an email can be attached, which are useful non-obvious details. However, it does not mention side effects on existing data, whether the note field interacts with updates, or any required permissions. The transparency is partial, so a score of 3 is warranted.

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?

The description is concise, consisting of two sentences with no superfluous wording. The first sentence front-loads the primary action, and the second adds typical use cases. It is efficient, though the omission of the note parameter could be seen as a missed opportunity, but that is a completeness issue rather than a conciseness flaw.

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?

Given the tool's complexity (4 parameters, a nested email object, no output schema, and no annotations), the description is too sparse. It fails to explain the note field, the email object's subfields, the required application parameter, and the behavior when both status and email are supplied. An agent would lack crucial information to call this tool correctly, so contextual completeness is low.

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?

Since the input schema has no property descriptions (coverage 0%), the description must explain parameter meaning. It covers the 'status' parameter ('set a new status') and the 'email' parameter ('attach an email update'), but it completely omits the 'note' parameter and fails to clarify that 'application' is an identifier. The structure of the nested email object is also left unexplained. Half the parameters are undocumented, so the description does not sufficiently compensate for the missing schema details.

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 clearly states the tool's function: manually update an application's tracking by setting a new status and/or attaching an email. It also lists common use cases (interviews, offers, rejections, withdrawals) which helps distinguish it from sibling tools like get_application_status (read-only) and apply_to_job (automated). The verb and resource are specific and 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?

The description provides context on when to use the tool by listing typical recording scenarios, but it does not explicitly mention alternatives or exclusion criteria. It does not clarify that this is for manual updates only, nor does it contrast with automatic processes. The guidance is adequate but lacks explicit boundaries.

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