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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description's only added behavioral fact is the 'newest first' ordering, which is genuinely useful, but it says nothing about pagination, empty results, or what a note record contains.

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 front-loaded sentence with no filler; the verb, resource, ordering and optional scope all appear before any qualifying clause.

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 simple, read-only list tool with rich annotations the description covers the essential purpose. But with no output schema, it could reasonably say what a returned note looks like or how the topic filter is discovered, and it leaves the limit parameter entirely unaddressed.

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?

Coverage is 50%: 'topic' is documented in the schema (a slug from list_topics), and the description merely restates it as 'optionally within one topic'. The 'limit' parameter is never mentioned anywhere, so the description does not compensate for the coverage gap or clarify that it caps result count (1-20, default 10).

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 ('List the most recently published notes') plus the ordering ('newest first') and an optional scope ('within one topic'), so the agent knows exactly what it returns. It does not name or contrast any sibling (search_notes, related_notes), so sibling differentiation is left to inference.

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?

'Optionally within one topic' implies the default unfiltered browsing case, which hints at when to use it. However, there is no explicit statement of when to prefer this over search_notes or related_notes, and no exclusions or prerequisites are given.

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