compress_add_static

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

With no annotations, the description must disclose behavioral traits, but it only states that compression is added. It does not explain side effects such as in-place file modification, overwriting behavior, required permissions, api_key usage, or the result of the operation.

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 very short and contains no fluff, which is good for conciseness. However, it is under-specified and omits important context, making it less 'appropriately sized' than a description that balances brevity with necessary detail.

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?

The tool has a required 'directory' parameter and an undocumented 'api_key', no output schema, and no annotations. The description does not explain how these parameters relate to the action or what the outcome of adding static asset compression will be, leaving the agent under-equipped to invoke it correctly.

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 only 50%; the 'directory' parameter has a description in the schema, but 'api_key' is completely undocumented. The description adds nothing about either parameter, so agents cannot infer the purpose or format of api_key.

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?

States a specific action ('Add') and resource ('static asset compression'), giving the core purpose clearly. However, it does not distinguish itself from overlapping siblings like compress_setup_gzip or compress_optimize, so it lacks 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 such as compress_setup_gzip or compress_optimize. There is no mention of prerequisites, target asset types, or situations where a different compression tool would be preferred.

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