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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so safety is covered. The description adds real context — results are paginated metadata retaining source clocks, rights and access states, and Seiche values are not copied — but it omits practical traits like total counts, page traversal behavior, or what an empty page means. The phrase "external trade" sits slightly awkwardly against openWorldHint=false but does not clearly contradict it.

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 sentences, front-loaded with the core capability, with no obvious filler. However, the final sentence about the Seiche research_network handoff is dense and ambiguous — it is unclear whether the tool returns a pointer, an embedded summary, or nothing at all.

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 and no parameter documentation, the description must carry more weight than it does. It establishes what metadata fields come back and that values are not duplicated from Seiche, but an agent still lacks the return shape and paging semantics needed to consume results confidently.

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% for the two parameters, and the schema only carries types, defaults and bounds. The single word "Paginated" implies limit/offset exist but gives no guidance on sensible page sizes, the 25 max, or the 1000 offset ceiling, so the description does little to compensate.

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?

Uses a specific verb ("Discover") with a clear resource ("every Palimpsest dataset") and enumerates the catalog's coverage areas, so an agent knows this is the broad catalog-listing entry point. It does not explicitly contrast itself with siblings such as get_newsroom or gfw_reading, but the catalog framing is distinct enough to infer the split.

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 says what the catalog contains but never states when to reach for it versus alternatives like inspect_economic_publication_rights or get_signal. The Seiche "handoff" sentence hints that follow-up context lives elsewhere, yet no condition or routing rule is given.

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