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

With annotations already declaring readOnlyHint=false, idempotentHint=false and openWorldHint=true, the description adds real value beyond them: 'May incur charges' flags a financial side effect and 'Requires exact user approval in BEON PASS' discloses a mandatory authorization step. It still says nothing about what happens on success/failure or how the approval is obtained.

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?

Three short sentences, all front-loaded: action first, then cost risk, then authorization requirement. No filler or repetition; every clause carries information.

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 nine-parameter mutating tool with no output schema and 0% schema description coverage, the description omits the meaning of the approval/beon parameters and any sense of what is returned or what failure looks like. The cost and approval notes are useful but far short of complete.

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 nine parameters, so the description carries the full documentation burden, yet it only indirectly alludes to approval_id and explains none of the beon_* context/resume/release/environment plumbing fields, nor team_id. This leaves most parameters semantically opaque.

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 ('Create a Vercel project'), which is immediately understandable. However, it does not distinguish itself from the very close sibling vercel_create_project_from_repository, so an agent cannot tell from the description alone which creation path applies.

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?

It implies a usage condition via 'Requires exact user approval in BEON PASS', which tells the agent a gated approval workflow must precede the call. But there is no explicit when-to-use/when-not guidance and no mention of the alternative creation tool, so routing must be inferred.

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