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

With no annotations provided, the description carries full burden for behavioral disclosure. It only states the basic function without mentioning any behavioral traits like pagination, rate limits, authentication requirements, result format, or whether it's a read-only operation. For a search tool with zero annotation coverage, this leaves significant gaps in understanding how the tool behaves.

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 description is extremely concise at just 5 words, with zero wasted language. Every word contributes to understanding the tool's purpose. It's front-loaded with the core function and doesn't include unnecessary elaboration.

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?

Given no annotations, 0% schema description coverage, no output schema, and 2 parameters, the description is incomplete. It covers the basic purpose but fails to address parameter details, behavioral characteristics, or result format. For a search tool that likely returns multiple results, more context about how to interpret and use the output would be valuable.

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%, so the schema provides no parameter documentation. The description mentions 'by keyword' which hints at the 'query' parameter's purpose, but doesn't explain what constitutes a valid keyword, search syntax, or how results are ranked. It completely ignores the 'limit' parameter. The description adds minimal value beyond what's inferable from parameter names.

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 clearly states the action ('Search') and target resource ('RFCs'), and specifies the search method ('by keyword'). It distinguishes from the sibling tools get_rfc and get_rfc_section by indicating this is a search operation rather than retrieval of specific RFCs or sections. However, it doesn't explicitly contrast with siblings beyond the verb choice.

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?

The description provides no guidance on when to use this tool versus the sibling tools get_rfc or get_rfc_section. There's no mention of alternatives, prerequisites, or specific contexts where this search tool is preferred over direct retrieval methods. The agent must infer usage from the tool name alone.

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