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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is known. The description adds meaningful context beyond annotations: it requires an API key, returns newest-first lists, and flags poster/brief text under `_untrusted`. It does not discuss rate limits or pagination behavior, so it is not exhaustive.

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 purpose is front-loaded in the first sentence, and the subsequent explanation of `posted` and `matched` shapes is dense but earns its place. A bulleted structure might improve scanability, but there is little wasted text.

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 no output schema, the description compensates by explaining the returned `posted` and `matched` structures, including fields like `matched_sellers`, `bids`, `my_bid`, and `_untrusted`. It also covers API-key requirements and ordering, leaving little an agent needs to infer before calling the tool.

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 `limit` and `status` are already documented in the schema. The description adds only 'Filter with `status`', which reinforces the schema but contributes no new syntax or edge-case semantics. Baseline 3 is appropriate when the schema carries parameter meaning.

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: 'Your side of the job board', and breaks it into `posted` and `matched` sections with their returned fields. It effectively distinguishes this personal job view from generic job search tools by tying it to the caller's API key and personal activity.

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?

It gives concrete guidance for follow-up actions: use getBids(job_id) to read bids and closeJob to stop taking them. It also explains filtering with `status`. However, it does not explicitly contrast myJobs with siblings like searchJobs or myListings, leaving broader usage to inference.

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