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

readOnlyHint=true already establishes the safety profile, so the description is not carrying that burden. It adds only the upstream endpoint reference (GET /bookings) and the vague 'recent' scoping hint; it says nothing about default ordering, whether cancelled bookings are included, or how many results a caller should expect before paging.

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?

Two sentences, front-loaded with the action and scope, followed by the filter surface. The trailing 'TrekkSoft API: GET /bookings' is marginal but cheap and aids API mapping; nothing else is wasted.

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?

All 10 parameters are self-documented and the read-only annotation covers safety, but with no output schema the description should say more about what a result row contains, pagination totals, and default sort/recency window. For a 10-param list endpoint that is a noticeable gap.

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 baseline is 3. The description's filter list maps almost one-to-one onto parameters already documented in the schema and adds no formats, defaults, or interaction rules (e.g. how q combines with user or merchant) beyond what the schema states.

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?

Specific verb+resource ('List recent bookings') with an enumerated set of supported filters, which clearly separates it from the singular trekksoft_get_booking sibling. The qualifier 'recent' is left undefined, so the retrieval scope is imprecise.

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 list of filter dimensions implies when the tool is appropriate (browsing/searching bookings), and the presence of q/user/merchant hints at broadening-narrowing usage. However, it never states when to prefer trekksoft_get_booking for a single record, nor any exclusion or prerequisite such as required merchant scoping.

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