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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and openWorldHint=false, so the safety profile is covered. The description does add real context beyond them: it is 'public' (no tenant/auth scoping) and explicitly disclaims that results are 'no verified match' and carry 'no autonomous commercial authority', which cautions the agent against over-interpreting output. It stops short of saying what the response actually contains or its format, which matters since there is no output schema.

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, no padding, with the identity/disclaimer framing up front. It is efficient, though the telegraphic phrasing costs some readability.

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 no parameters and no output schema, the description carries the burden of explaining what the agent receives, and it only gestures at that ('identity and ... handshake instructions'). A brief note on the returned content and its role as a first step would close the 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?

The tool takes zero parameters and the schema is closed with additionalProperties=false, so there is nothing to document; baseline for a 0-param tool is 4. The description correctly implies a parameterless call.

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 identifies the resource as 'Public FrankoX agent identity and safe pre-tenant handshake instructions', which hints at a discovery/bootstrap endpoint, but it never uses a clear verb and leans on internal jargon ('pre-tenant handshake'). It does not distinguish itself from the sibling tool 'external_business_handshake', so an agent cannot tell which of the two to reach for from the text alone.

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 statement of when to call this versus 'external_business_handshake', 'discover_network_intents', or the search_* tools. The phrase 'pre-tenant' weakly implies 'call this first', but that ordering is left entirely to inference.

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