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

Annotations already cover read safety (readOnlyHint=true); the description adds meaningful context beyond that: the data is public, paused worker availability is still returned (so absence of results does not mean nothing exists), and results are not a quality or price certification. It stops short of describing the shape or size of the returned declarations.

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?

Three short, front-loaded sentences with no filler; the scope constraint and the public/visibility caveats appear early. The domain jargon ('worker declarations', 'grant path') is dense without being wasteful, though a first-time reader may need to re-read.

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 one-parameter read tool with readOnlyHint and no output schema, the description is adequate but the core nouns it promises ('worker declarations', 'Work Ticket grant path') are never unpacked, so an agent cannot anticipate what it will receive or how to use it downstream.

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% — the single merchantId has only a uuid format and pattern, no textual meaning. The description partially compensates by stating the merchant must be a 'known merchant', implying an existing entity rather than an arbitrary ID, but it gives no guidance on where that ID comes from or what happens for unknown merchants.

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 a specific verb ('Inspect') and a specific resource (a known merchant's opted-in worker declarations plus the Work Ticket grant path), which separates it from the sibling get_my_worker_profile (own profile) and set_worker_profile (write). It is not explicitly contrasted with those siblings, so it stops short of 5.

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 implied by 'known merchant' — the caller must already have a merchantId — and by 'Public' indicating no auth prerequisite. But there is no explicit when-to-use/when-not guidance against search_workers or get_my_worker_profile, and no stated precondition for obtaining a merchantId.

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