cypress_get_env

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explicitly mentions that sensitive values are masked and that the output is safe to display, providing valuable context. However, it does not specify masking details, error behavior, or output format, leaving some gaps.

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 exceptionally concise, with two short sentences that convey the core functionality and safety property. There is no redundant or filler content, and the key information is immediately presented.

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 zero-parameter tool with no output schema, the description adequately covers the tool's purpose and key behavioral trait (masking). It does not describe the output format or potential issues like a missing file, but given the simplicity, the information is reasonably 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?

The tool has zero parameters, and the schema is empty, so there is nothing for the description to clarify. The baseline for 0 params is 4, and the description appropriately does not overcompensate for nonexistent parameters.

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 states the tool returns the contents of cypress.env.json with sensitive values masked, using a specific verb and resource. This distinguishes it from sibling tools focused on running, analyzing, or inspecting specs and test results.

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 implies usage for viewing environment configuration by noting it is 'Safe to display' and returns the contents. However, it does not explicitly state when to use this tool over alternatives or provide any exclusions or prerequisites, so guidance is only implied.

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