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

Annotations already establish read-only, idempotent, closed-world behavior, so the description is freed to add real context: that directly-licensing 'on request' publishers are returned separately and only on the first page. That first-page-only caveat is a genuine behavioral quirk an agent could otherwise miss. It does not mention result ordering or total counts, 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?

Four dense sentences with the core resource statement front-loaded, then the on_request exception, then filters, then access. No filler or repetition. Slightly information-dense with an embedded caveat that could be separated for scannability.

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 naming the returned fields and the secondary on_request collection, so an agent knows what to expect. Combined with the access-level note and filter list, this is nearly sufficient for a zero-required-parameter list tool. Ordering/pagination semantics for the main list remain unstated.

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 the schema already defines limit, offset, category substring matching, verified default, and min_articles. The description mostly restates the filter names without adding format or interaction detail. The one value-add is the note that the on_request list is limited to the first page, which ties to pagination behavior.

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 and resource ('Lists the publications on Opedd') and enumerates the returned fields (article counts, licences, prices, sample articles). It also carves out the 'on request' subset into a separate response key, which sharpens the scope. It does not name a sibling tool (e.g. browse_registry, search_content) to differentiate against, so it stops short of a 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?

Implies usage through the filter list (category, min_articles, verified) and the access note ('Public; no key needed'), which helps an agent know it can call this freely. However, there is no explicit when-to-use/when-not guidance relative to siblings like browse_registry or search_content, leaving the routing decision to inference.

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