config_add_environment

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

With no annotations supplied, the description carries the full burden of disclosing behavioral traits. 'Add' implies a mutation, but it does not reveal potential side effects, required permissions, persistence behavior, or the outcome of the operation. For a configuration-changing tool, this is a significant gap.

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 a single, concise sentence that is front-loaded and to the point. All words are meaningful, and it avoids unnecessary verbosity. However, it is so brief that it borders on under-specification, preventing a perfect score.

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?

Given that this is a config mutation tool with no annotations and no output schema, the description is too minimal. It does not explain what an environment is, what happens when one is added, or any implicit consequences. For a tool that alters configuration state, more context is needed.

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 input schema has 100% description coverage for its two parameters (name and description), so the baseline is 3. The tool description adds no further parameter semantics beyond what the schema already provides, making it neutral.

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 'Add a new environment' clearly states the action (add) and the resource (environment), which distinguishes it from sibling tools like config_switch_environment or config_remove_environment. However, it does not elaborate on what 'environment' means in this context, so it's slightly above average but not fully differentiated.

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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, scenarios, or why one would add an environment. The description simply states the action without contextualizing it among the many config_* siblings.

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