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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. Beyond that the description only adds which fields are searchable; it says nothing about partial vs exact matching, case sensitivity, result limits, or pagination, leaving real behavioral questions unanswered.

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?

One short sentence with no filler, and the searchable fields are stated up front. It is not maximally effective only because the brevity leaves behavioral gaps unfilled rather than because of wasted wording.

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?

The tool is simple (one required string parameter, full schema coverage, clear read-only annotations, no output schema), so the description does not need to explain return values. However, for a search tool the matching semantics and result-count behavior are the key unknowns an agent would want, and those are absent.

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 coverage is 100% and the single `query` parameter is already documented with a 200-character limit. The description adds a little by stating that "keyword" matching is supported in addition to URL/name, but gives no syntax for combining terms or matching rules, so it stays at the baseline.

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?

The description uses a specific verb ("Searches") and resource ("monitors") and names the three fields the query can match (target URL, keyword, name). It implicitly distinguishes itself from list_monitors by being a query-driven lookup, though it never names that sibling explicitly.

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 only implied: an agent can infer this is the tool to reach for when it has a search term rather than wanting the full monitor list. There is no explicit when-to-use/when-not guidance and no pointer to list_monitors as the alternative for unfiltered retrieval.

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