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 description's "read-only" restates structured data. It does add real value by describing the return shape ("bounded matched sections with source links"), which matters because there is no output schema, but it doesn't say how bounding works, what happens with zero matches, or how sources are linked.

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 short sentences, front-loaded with purpose, with no filler. The parenthetical "synthetic, shared" metadata is marginal but not verbose enough to cost more than one point.

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 two-parameter read tool with full annotations, the description covers purpose and a rough return shape, which is enough to attempt a call. It is incomplete on parameter meaning and result bounding, both of which the agent must guess.

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 0% for two parameters, so the description must carry the burden and it says nothing about either. "query" is never described (matching behavior, phrasing expectations) and "limit" (1-8, defaulting behavior) is not mentioned at all, even though "bounded" hints at it without explaining it.

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 ("Search the actual product documentation") and what comes back ("bounded matched sections with source links"). It does not differentiate from the sibling docs_lookup, so it stops short of a 5, and the leading "DEMO portfolio (synthetic, shared, read-only)" prefix mixes environment context into the purpose statement.

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 it should call this when it needs documentation content. There is no statement of when to prefer this over docs_lookup, no exclusions, and no note on query formulation or empty results.

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