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

No annotations are provided, so the description carries the entire behavioral burden. It characterizes the assessment's analytical content but says nothing about safety profile, whether it is read-only or mutating, authentication requirements, rate limits, or the meaning of the session_id-based state coordination. That is a substantial gap 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 the domain ('PHASE 1 B2A') and the core action. Efficient, though the cryptic phase/prefix consumes the opening position without conveying meaning to the agent.

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 output schema, the description helpfully outlines the return content (risk factors, chokepoint status, delay probabilities), which is the strongest part of the definition. But for a 7-parameter tool with zero annotations it omits routing guidance and any behavioral caveats, leaving the definition only minimally complete.

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 71%, so the parameters (corridors, transit_mode enum, hazardous_material, session_id) are largely self-documenting and the baseline is 3. The description enumerates what the analysis covers rather than clarifying any input, so it adds little to the schema.

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: 'Assesses supply chain freight corridor risks' with a concrete scope (chokepoints, bunker fuel index, transit delay probabilities). The action is distinguishable from the many non-risk siblings, though the 'PHASE 1 B2A' prefix is opaque jargon and it never contrasts itself with near-neighbors like geo360_b2a_customs_gate or geo360_b2a_price_context.

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 instruction, no prerequisites, and no reference to any alternative tool. In a 25-tool catalog with three other 'b2a' siblings, the absence of routing guidance leaves the agent to infer selection from the name alone.

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