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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true, so the safety profile is covered. The description earns credit by adding what gets destroyed (all deployments, i.e. a cascade) and the BEON PASS approval workflow, which annotations do not convey.

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 tight sentences, front-loaded with the action and its scope, followed by the gating requirement. Every clause carries information and there is no filler.

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 destructive 8-parameter tool with no output schema, the description covers purpose, cascade impact and the approval prerequisite adequately, and annotations carry the safety signal. It remains incomplete on the beon_* parameter family and on whether deletion is recoverable, leaving gaps for an agent to call it confidently.

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% across 8 parameters, so the description must compensate and largely fails to do so. It alludes to an approval step that maps loosely to approval_id, but the required id and the six beon_* parameters are left entirely unexplained.

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 ('Delete a service') and adds the important scope detail that all deployments go with it. It does not explicitly contrast with siblings such as railway_delete_project or railway_delete_environment, so an agent must infer which deletion tool applies, but the cascade note already distinguishes it somewhat.

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 gives one real precondition ('Requires exact user approval in BEON PASS'), which is actionable context for invoking the tool. However it offers no when-to-use framing, no alternatives for the non-destructive paths, and no signal that this is irreversible beyond the approval gate.

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