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

With no annotations, the description carries the full behavioral burden. It usefully discloses a state transition ('transitions consignment status to PHYSICAL_DELIVERY_CONFIRMED') and a validation step on the eIDAS seal, which tells the agent this is a mutation with a pass/fail gate. However, it omits what happens on seal-validation failure, error behavior, idempotency, and permission requirements.

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 dense sentences, front-loaded with the phase tag then the action and its effect. The 'PHASE 3 B2A' prefix is cryptic process metadata but compact, and nothing is wasted.

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?

No output schema and no annotations, so the description must cover behavior, and it does surface the resulting status. For a mutation tool it still leaves gaps around failure modes, auth, and return shape, so an agent would know what it does but not fully how it behaves.

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%, so all six parameters are already documented in the schema. The description restates e-CMR and eIDAS seal concepts that map to required params but adds no syntax, format, or defaulting detail beyond 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?

The description gives a specific verb ('Confirms') and resource ('physical freight receipt at destination hub') and names the resulting state ('PHYSICAL_DELIVERY_CONFIRMED'). It situates the tool in a workflow ('PHASE 3 B2A') but never names the sibling it follows (e.g. geo360_logistics_dispatch_packet), so differentiation is implied rather than explicit.

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 'PHASE 3' marker and the reference to e-CMR receipt imply this is called after dispatch, but there is no explicit when-to-use vs. alternatives, no stated preconditions beyond the required seal, and no exclusions. Usage is inferable from the phase label rather than stated.

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