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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description adds genuinely new behavioral context beyond that: results are filtered to what the user can see and to kinds the token may read, and it discloses the hit shape (id, kind, workspace-relative path).

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?

Three dense, front-loaded sentences with no filler: purpose and coverage first, routing second, return/scope semantics last. Every clause carries information the agent can act on.

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?

No output schema exists, so the description carries the return-value burden and does so by describing the id/kind/path tuple and how the id feeds *_get tools. Combined with the permission scoping note, an agent has everything needed to call and use this correctly.

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 75%, so most parameters are already documented structurally. The description reinforces name/title matching but adds no new syntax or format detail for kinds, limit, or workspace, so the baseline 3 is appropriate.

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?

Opens with a specific verb (Finds) and resource (entities across every tool by name), then enumerates the concrete kinds covered (flows, pages, datasets, evals, rubrics, etc.). An agent can immediately distinguish this cross-tool search from the many per-tool list siblings.

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?

Explicitly states when to use it ('Use it FIRST when the user names something without saying where it lives'), gives concrete examples ('the onboarding flow'), and names the alternative plus its selection condition ('reach for a tool's own list only when you already know the tool'). This is textbook when/when-not/alternative routing.

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