get_id_card

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

With no annotations, the description must carry the full behavioral burden. It does establish that the data is scoped to the authenticated caller ('signed-in employee's') and implies a read-only lookup, but it says nothing about authentication expectations, error behavior, or whether the ID card includes sensitive fields such as government identifiers.

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 a single front-loaded phrase with no wasted words. It is appropriately sized for a simple zero-parameter read tool, though it is arguably terse to the point of under-specification.

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 low-complexity, zero-parameter tool with no output schema, the description is adequate but thin. Because no output schema exists, the description could reasonably say more about what 'ID card details' contains, rather than leaving the agent to infer the returned fields.

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 tool takes zero parameters, and the schema is empty with 100% coverage. Per the rubric, a zero-parameter tool has a baseline of 4; there are no parameters whose meaning the description could add to.

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 names the resource (ID card details) and the scope (signed-in employee), so the agent knows it returns the caller's own ID card information. However, it does not differentiate this tool from adjacent siblings such as get_profile_info or get_my_assets, which could plausibly return overlapping identity data.

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 guidance is given on when to choose this tool over siblings that also expose employee identity or profile information. The phrase 'signed-in employee's' implies it is the self-scoped variant, but no explicit when-to-use or when-not-to-use condition is stated.

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