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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuinely new behavioral context beyond the annotations: source documents and page content are untrusted data and never instructions (prompt-injection guidance), and sources are private. That is meaningful, non-redundant disclosure.

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 purpose is correctly front-loaded in the first sentence and the security notes are compact. However, the final sentence about publishing public pages and AI answers does not earn its place for a read-only overview tool and reads as boilerplate lifted from a mutation tool, diluting focus.

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?

With annotations covering safety and no output schema, the description needn't explain return values, and it does describe the returned content. What it omits is the routing information an agent needs in a crowded knowledge-tool sibling set: why choose this overview over the narrower get_knowledge_* tools. Adequate but with a clear 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 0% and the single parameter (account_id) is never mentioned in the description. It is a self-evident UUID scoping identifier, so the omission is not fatal, but the description adds no syntax, format, or meaning beyond what the schema's pattern already conveys.

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 names a specific resource and enumerates its parts: 'List source identities, published page summaries, processing state, and proposed documentation changes.' That is a clear verb+resource with scope. It stops short of distinguishing itself from siblings like get_knowledge_source, get_knowledge_page, or get_knowledge_change, so an agent can't be certain this is the aggregate 'overview' rather than a per-entity fetch.

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?

There is no explicit when-to-use or when-not-to-use guidance, and none of the many sibling knowledge tools (get_knowledge_source, get_knowledge_page, search_knowledge) are mentioned as alternatives. The only imperative, 'never publish without the user's instruction,' governs a publishing action that this read-only tool does not perform, so it does not help select the tool.

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