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

The description adds an explicit authorization requirement ('Required scopes: files:write') and explicitly states the operation mutates server state. This goes beyond the annotations' readOnlyHint=false by telling the agent what scope is needed. It does not mention overwrite behavior or whether source files are preserved, but the annotations already convey the non-destructive safety profile, so this is reasonably transparent.

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 front-loaded with the core action, followed by terse metadata lines. Every line is useful even if 'Mutating: changes server state' is partly redundant with the annotations, and there is no unnecessary prose.

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 mutating operation with a nested body and no output schema, this description is thin. It omits what archive_path should be, whether source files are removed or preserved, whether an existing archive is overwritten, and what response an agent should expect. It is enough for basic tool selection but not for confident invocation without external API knowledge.

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 description itself adds no parameter-level meaning, but the input schema carries most of the load: body is described as a JSON request body, format lists 'zip, tar.gz, etc.', and user_id says 'Target user ID'. Since schema description coverage is reported as 100%, a baseline of 3 applies; source_paths and archive_path still have empty descriptions, but the description does not make that gap worse.

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 a specific verb and resource ('Compress files') and gives the exact HTTP endpoint, so an agent can tell this is the compression operation. It is unambiguous against sibling operations like extract/copy/move, though it does not explicitly name alternatives or state that it creates an archive at archive_path, so it stops short of a 5.

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 provides only metadata (endpoint, category, required scope, mutation flag) and no when-to-use guidance, exclusions, or mention of sibling alternatives. An agent must infer usage from the tool name alone, making this essentially guidance-free for selecting between tools.

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