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

Annotations already declare destructiveHint=true and idempotentHint=false, so the safety profile is largely covered. The description adds real context beyond the annotations: the deletion is permanent and cascades to child resources, and it requires an out-of-band approval workflow. It does not, however, explain how the approval is obtained or how the approval_id parameter relates to that workflow.

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, zero filler, with the destructive scope front-loaded ahead of the approval prerequisite. Nothing to trim.

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 0% schema coverage and no output schema, this is thin. The agent learns the operation is permanent and needs approval but cannot tell from the description how to populate the approval and BEON context parameters required to actually invoke it successfully.

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 coverage is 0% across 8 parameters, so the description carries the full explanatory burden and mostly fails it. It hints at the approval mechanism via 'exact user approval in BEON PASS', which loosely gestures at approval_id, but seven parameters (beon_app_id, beon_context, beon_resume_id, beon_release_id, beon_environment, beon_connection_id, approval_id) 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 (delete) and resource (project) plus the scope of impact ('and its resources'), which distinguishes it from railway_delete_service and railway_delete_environment. It stops short of explicitly naming those sibling alternatives, but the resource level alone makes the target unambiguous.

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 notes a prerequisite ('Requires exact user approval in BEON PASS') but offers no when-to-use guidance, no conditions that select this tool over the narrower delete_service/delete_environment siblings, and no warning about cascading deletions. Prerequisite information is present, but selection guidance is absent.

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