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

The annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is covered. The description adds behavior the annotations don't: it returns slug + one-line summary per page, and 'every page' signals completeness rather than a sampled result set. Pagination/truncation behavior for a full-corpus listing is still unstated.

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?

A single front-loaded sentence: action, resource, return shape, then the intended use. No filler or redundancy.

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 a single optional parameter documented in the schema, full annotation coverage, and no output schema, the description carries what's needed: what the tool returns and when to reach for it. Minor gap is that 'every page' is not reconciled with the audience filter that narrows the list.

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 100% and the audience enum is fully explained in the schema (including the 'omit to search both' default). The description never mentions the audience filter at all, so it adds nothing over the schema — baseline 3 applies.

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?

Specific verb ('List') plus resource ('every page in Axons Mobility's public knowledge base') plus the returned payload ('slug and a one-line summary'). The trailing clause 'before searching' implicitly separates it from search_help, so an agent can pick it apart from siblings without opening schemas.

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?

Gives clear usage context — browse the full corpus before doing a search — which sequences it correctly relative to search_help. It never names search_help or read_help_page explicitly, nor states exclusions, so it stops short of full routing guidance.

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