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

The description adds meaningful safety context beyond the sparse openWorldHint annotation: it notes that delete requires explicit confirmation, that reveal is opt-in, and that instance is optional. It does not cover broader behaviors like auth or error handling, but the safety flags are relevant and actionable.

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?

The description is compact and well-structured into scope, action list, and safety notes. Every sentence earns its place, and the use of a single-line signature per action keeps it scannable without redundancy.

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 14-parameter, multi-action tool with an output schema, the description covers the action set, scope, required confirmations, and param action-specificity. It lacks examples or deeper return semantics, but the output schema and per-action signatures make the tool sufficiently complete for an agent to select and invoke it.

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?

The action signatures in the description add per-action applicability and optionality that the flat schema doesn't convey, such as 'name' being required for create and optional query parameters for list/get/delete. Since schema descriptions cover 100% of parameters, the baseline is 3, but the action grouping adds meaningful selection semantics.

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 clearly identifies the tool as 'Environment CRUD scoped to a parent project', with an explicit note that there is no update action. It enumerates all five actions, making the tool's purpose and scope immediately distinct from siblings like project or deployment.

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?

The description gives clear context: it's for environment operations scoped to a parent project and explicitly excludes the update action. It does not name alternative tools or provide direct when-not-to-use guidance beyond the no-update caveat, but the action list and scope define suitable usage well.

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