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

No annotations are provided, so the description carries the behavioral burden. It discloses the Markdown response format, the kind of metadata shown (icon, last-edited date), and that the tool returns IDs suitable for downstream operations. It does not discuss pagination, sorting, or no-result behavior, so it is good but 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?

The description is compact: a one-line purpose, a routing sentence, and a concrete example. Every section adds distinct value with no redundancy, and the main action is front-loaded.

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?

Since there is no output schema, the example output compensates well by showing the exact list format, ID style, and metadata. The description also covers downstream usage across siblings, and the input schema already covers parameter constraints. Missing details like pagination are non-critical for a search tool.

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?

All three parameters are already fully documented in the schema (100% coverage), so the baseline is 3. The description adds no new parameter-level meaning beyond the schema; it reinforces how returned IDs are used afterward, which is useful but not parameter semantics.

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 opens with a specific verb ('Search'), resource ('the Notion workspace'), and scope ('by title keyword'), and immediately defines the return shape as a Markdown list with page/database IDs, titles, and metadata. The example output further clarifies the purpose and distinguishes it from read/list/write tools.

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?

It explicitly tells the agent to use returned IDs with other tools and names each sibling role: read (get full content), write (update), list (query a database), delete, or move. This is strong routing guidance; no explicit 'when not to use' is needed because the alternatives are clearly assigned.

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