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

With no annotations provided, the description carries the full burden and handles it well: it discloses that compression is full-scale, that summaries and metadata are retained, that original content is archived rather than deleted, and that storage is freed. It does not discuss reversibility or permissions, so it stops short of a 5.

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?

A single em-dash-joined sentence packs action, scope, retained data, archival behavior, and the storage benefit with no filler. Key information is front-loaded and every clause earns its place.

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 simple one-parameter tool with no output schema, the description is largely complete: the target and outcome are clear, and the archival guarantee addresses the main safety concern. It lacks explicit usage guidance and any statement about reversibility, but those are modest gaps at this complexity level.

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 the baseline of 3 applies. The description only echoes 'specified layer' and adds no meaning beyond the schema's layer enum and default value, which are already documented in the input schema.

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 a specific verb and resource: full compression of a specified layer, with concrete outcomes (retain summaries/metadata, archive originals, free storage). It is clearly the compression tool among the siblings, though it does not explicitly name or contrast an alternative.

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 phrase '释放存储空间' implies the intended purpose and '指定层级' implies scope selection, so usage context is somewhat implied. However, the description gives no explicit when-to-use guidance, no exclusions, and no mention of alternative tools.

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