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

With no annotations, the description carries the full burden. It usefully discloses that the full section text (not a summary) is returned, which is a real behavioral trait. However, it says nothing about behavior for an unknown/ambiguous section name, permissions, or whether the section list is discoverable, leaving meaningful gaps for an unannotated tool.

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 that leads with what is returned. The example list is relatively long but each example is informative rather than filler, so the sentence earns its length.

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 one-parameter read tool with no output schema, the description covers the core behavior adequately. It omits what happens on a missing or mismatched section name and gives no way to enumerate valid sections, which matters because the parameter is free-form with no enum.

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 100% and the schema's own text ('Name or keyword of the section to retrieve') is thin, so the description's concrete examples ('Skills and Certifications', 'Projects and Clients', etc.) add genuine meaning about acceptable values. It stops short of stating matching semantics (exact vs keyword match), so not a 5.

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: 'Returns the complete text of a specific section from the site's knowledge base.' The parenthetical examples of section names make the scope concrete. It does not explicitly contrast itself with siblings like 'ask', but the retrieval-of-known-section framing is distinct enough to be actionable.

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 this is for fetching a section whose name it already knows, versus 'ask' for open questions, but neither the alternative nor a when-not condition is stated. The section-name examples hint at the domain without giving routing guidance.

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