record_application

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

With no annotations provided, the description carries the transparency burden and does so well: it discloses the upsert-like behavior, the special handling of final-status applications, and the guarantee that re-applications never overwrite earlier outcomes. It does not discuss authorization or broader side effects, but the key behavioral contract is explicit.

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 tightly written: a one-line summary is followed by a compact explanation of the branching logic. Every sentence carries useful information and no filler is present.

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 description delivers the critical behavioral rules needed to avoid destructive overwrites, and an output schema exists to cover return values. However, for a tool with 8 parameters, no annotations, and zero schema documentation, the undefined status vocabulary and undocumented non-key parameters leave meaningful gaps for an agent trying to call it correctly.

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%, so the description is the only source of parameter meaning. It explains the significance of company, role, and status by referencing 'OPEN' and 'final status,' but says nothing about notes, source, channel, deadline, or fit_rating, leaving most of the 8 parameters semantically undocumented.

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 uses a specific verb-resource pair ('Create or advance an application record') and immediately distinguishes its behavior from read-only siblings by explaining the update-vs-create branching. It is clear that this tool is the mutation path for application records, not a lookup or job-management tool.

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 practical context about when an existing open application is updated versus when a new row is created, but it does not explicitly state when to prefer this tool over alternatives or mention any exclusions. The intended use is inferable from the name and resource, but no sibling comparison is given.

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