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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered structurally. The description adds the non-obvious filtering behavior (BEON PASS infrastructure excluded) and the authorization scoping, which is genuinely useful context, but says nothing about pagination, result size, or what 'authorized' is derived from.

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 tight sentence with the key constraint front-loaded; nothing is wasted. It is slightly under-specified rather than padded, so it errs toward brevity.

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, 7 undocumented parameters, and no required fields, the description should explain the auth/context contract and what a returned project looks like. It delivers only the exclusion rule, leaving the agent unable to construct a correct call 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 7 parameters, so the description carries the full burden of explaining what approval_id, beon_context, beon_environment, etc. mean. It mentions none of them, leaving the agent with seven opaque inputs and no way to know which are required context versus optional filters.

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 ('List authorized projects') and adds a meaningful scope qualifier. It does not, however, distinguish itself from the sibling list tools (railway_list_projects, vercel_list_projects) beyond the name prefix.

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 guidance on when to call this versus alternatives or what an 'authorized' project means in practice. Usage is only implied by the verb 'List'.

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