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

No annotations are provided, so the description carries the full burden. It discloses that results are ordered most-recent-first, which is a behavioral trait. However, it does not mention that the operation is read-only, nor any other side effects or constraints. For a simple retrieval tool, this is acceptable but not rich; the ordering note is useful but the description could also note the read-only nature.

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 concise sentence that front-loads the core purpose and adds the ordering detail. There is no waste; every word earns its place. It is appropriately short for a zero-parameter tool.

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 tool is simple with no parameters and an output schema is present, so the description does not need to explain return format. It covers the content and ordering, which is everything an agent needs to decide whether to call it and what to expect. No missing information for correct invocation.

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?

There are zero parameters and the schema is empty, so the baseline is 4. The description adds meaning beyond the empty schema by describing the content (work experience/employment history) and ordering (most recent first), which gives the agent context about what to expect from the output. Since there are no parameters to explain, the description suffices.

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 resource ('Rahul's work experience / employment history') and implicitly the verb 'list' or 'retrieve'. It distinguishes itself from siblings like education, patents, and projects by topic. The ordering note adds specificity.

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 clear context that this is for work experience, but does not explicitly state when to use it versus siblings or any exclusions. No alternative tools are named, so an agent must infer that this is the correct tool for employment history. The 'most recent first' note gives some usage context but not a full when-to-use guide.

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