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

No annotations are provided, so the description carries full burden. It states this is a creation operation, implying mutation, but doesn't disclose behavioral traits like permissions required, whether the creation is idempotent, what happens on conflicts, or what the response contains. For a mutation tool with zero annotation coverage, this leaves significant gaps in understanding how it behaves.

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, efficient sentence with no wasted words. It's front-loaded with the core action and resource. However, the bracketed '[application delivery]' prefix adds minimal value and could be integrated more smoothly.

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 this is a mutation tool with 6 parameters, no annotations, and no output schema, the description is incomplete. It doesn't address key contextual aspects like what the tool returns, error conditions, or how it fits into the broader system (e.g., relationship to other variable tools). The agent lacks sufficient information to use this tool effectively.

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 100%, so parameters are documented in the schema. The description adds no additional meaning about parameters beyond what's in the schema (e.g., it doesn't explain relationships between 'displayName' and 'name', or clarify the 'content' array structure). Baseline 3 is appropriate when the schema does the heavy lifting.

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 states the action ('Create') and resource ('global variable group'), which is clear but basic. It doesn't distinguish this tool from sibling 'create_variable_group' or explain what makes a 'global' variable group different from other variable groups in the system. The purpose is understandable but lacks specificity for sibling differentiation.

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 like 'create_variable_group' or 'update_global_var'. The description doesn't mention prerequisites, constraints, or typical use cases. Without this context, an agent must infer usage from the tool name alone.

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