File Fav Del

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

No annotations are provided, so the description carries the full behavioral burden. It usefully flags that this is a write operation, but says nothing about reversibility (whether the favorite entry is truly removed vs. moved to a recycle bin), permission requirements, or behavior when the path is not currently favorited.

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 single short phrase is front-loaded and free of filler, which is good, but it is under-specified rather than genuinely concise — there is no wasted text because there is almost no text at all.

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 mutation tool with zero annotation coverage, a rich five-parameter schema, and an output schema, a four-character description is inadequate. The agent knows it removes a favorite but not the scope, side effects, or error conditions it should anticipate.

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 all five parameters (host, path, port, scheme, profile) are already documented in the schema. The description adds no parameter-level meaning beyond that, so the baseline 3 applies.

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?

"取消收藏" conveys a specific verb+resource, but it is essentially a translation of the tool name file_fav_del rather than an independent statement of purpose. It does not distinguish itself from the sibling tools file_fav_add and file_fav_list beyond the obvious verb difference, leaving the agent to infer scope (single file vs. bulk, by path vs. by ID).

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 offers no guidance on when to invoke this tool, what preconditions apply (e.g., the path must already be favorited), or how it relates to file_fav_add/file_fav_list. The parenthetical "(写操作)" describes the operation type, not usage context.

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