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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, openWorldHint=true, so the safety profile is fully covered. The description adds the 'authorized workspace' scoping note, but says nothing about result size, pagination, or what authorization is required — a modest addition against an already-covered behavioral surface.

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 short, front-loaded sentence with no filler — structurally efficient. The terseness is closer to under-specification than ideal breadth, but every word earns its place.

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 an 8-parameter, 0%-schema-coverage tool with no output schema, the description is far too thin. It omits any explanation of the required workspaceId, the ancillary beon_*/approval_id parameters, and return shape, leaving the agent without enough context to invoke it competently for anything beyond the trivial case.

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, and the description compensates only implicitly by naming 'workspace' (the sole required workspaceId). The seven other parameters (approval_id, beon_app_id, beon_context, beon_resume_id, beon_release_id, beon_environment, beon_connection_id) are undocumented in both schema and description, including the two enums.

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 (List) and resource (projects) scoped to an authorized workspace, which is unambiguous on its own. However it does not distinguish itself from the sibling railway_get_project or explain the list-vs-get relationship, so an agent gets no help differentiating siblings 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 guidance on when to use this versus railway_get_project (single project) or railway_list_environments/railway_list_workspaces. No prerequisites, no mention of whether pagination or a required workspace scope drives usage. Only implied usage via the tool name.

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