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

With no annotations provided, the description carries the entire behavioral burden, and it does well: it discloses the non-transactional/non-gas nature of the operation, the authentication requirement (guests and non-keys are refused), name-validation policy, and the persistence/default behavior of the type field. It omits return shape, uniqueness/duplicate-name behavior, and idempotency, which are meaningful gaps for a creation tool.

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?

Six short sentences, front-loaded with the action before the constraints, and nearly every sentence carries usable information. It is slightly choppy and the trailing name rule is awkwardly phrased, but 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 four-parameter mutation tool with no annotations and no output schema, the description covers cost, auth, and naming rules well, but says nothing about what is returned (e.g., an environment identifier) or what happens on duplicate/invalid names beyond rejection. An agent can probably invoke it correctly, but not predict or handle the result.

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 50% — apiKey and sessionToken are documented in the schema, but name and type are bare. The description compensates by explaining that type defaults to research when omitted and by spelling out the name policy (real name of at least 6 characters, or a VEYA prefix, with rejected test-like prefixes). That said, the stated 6-character minimum conflicts with the schema's minLength of 1, adding ambiguity rather than clarity on that one point.

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?

Opens with a specific verb+resource: "Create a workspace in the product API." That is unambiguous about what the call does at the domain level. It does not, however, differentiate itself from close siblings such as veya_register_environment or veya_list_environments, and it freely swaps "workspace" for the tool's "environment" terminology, which could make an agent pause when both tools are visible.

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?

Gives concrete context for use: it does not spend gas and sends no transaction, guests and non-key callers are refused, and certain name prefixes (test, demo, tmp, sandbox, e2e) are rejected. These are real preconditions an agent needs before calling. There is no explicit statement of when to prefer this over a sibling like veya_register_environment, so it stops short of full routing guidance.

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