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

Annotations already cover the safety profile (readOnly, non-destructive, closed-world), so the description's contribution is ordering ('newest first') and the shape of what comes back. It says nothing about pagination, result caps, or how the status filter narrows results, which matters for a list tool on a potentially growing collection.

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 tight sentence with the scope front-loaded and no filler. The tail ('status, due time, price and credits') is slightly compressed and blurs whether these are returned fields or filters, a small cost to precision for the brevity gained.

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?

With only two optional, fully schema-documented parameters and no output schema, the description sensibly summarizes the return payload and ordering. The remaining gap is pagination/result-limit behavior, the main thing an agent would still need to know before calling it repeatedly.

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 100%, so both the status enum and passport_token are fully documented in the schema; baseline 3 applies. The description adds no filter semantics beyond what the schema provides — 'status' in its list reads as a returned field, which is actually mildly ambiguous against the status filter parameter.

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?

States the specific resource (owner's human service jobs) and scope qualifier ('done by AgentMart's own team'), plus ordering (newest first) and the fields surfaced. The singular/plural split from get_job is inferable from the name and the enumerating phrasing, though it is never said outright.

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?

Usage is only implied: an agent can infer this is the browse-many counterpart to get_job, and the parenthetical distinguishes these jobs from orders/other marketplace items. There is no explicit when-to-use, when-not-to-use, or named alternative such as get_job for a single job.

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