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

No annotations are provided, so the description carries the full behavioral burden, and it discloses essentially nothing: no confirmation that it is a read-only operation, no auth requirement (the schema implies apiKey/sessionToken but not that they are optional for reads), and no note on what happens when the id is unknown. By contrast, sibling parameters already carry credential semantics that the description ignores.

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 words, front-loaded with the verb and resource, with zero preamble or filler. It is efficient rather than bloated, though the extreme brevity arguably costs more in missing context than it saves in tokens.

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 tool with no annotations, no output schema, and a credential-bearing parameter set, the description should clarify the read-only nature, the auth model, and at least the notion of what an 'environment' returns. None of that is present, leaving the agent dependent on sibling conventions.

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 67%, and the apiKey/sessionToken parameters are documented in the schema itself, so the schema does the heavy lifting. 'By id' weakly signals that environmentId is the lookup key, but the description adds no format, source, or constraint information beyond what the schema already shows.

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?

The description names a specific verb and resource ('Get one environment by id'), which separates it from veya_list_environments at a glance. It does not, however, differentiate itself from the other single-environment readers in the sibling set (veya_read_environment_onchain, veya_public_get_agent-style lookups), so it stops short of a 5.

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 when-to-use guidance, no statement of prerequisites, and no routing to alternatives such as veya_list_environments for enumeration or veya_read_environment_onchain for on-chain state. The agent must infer selection entirely from the name.

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