cloudreve_upload_from_cache

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

No annotations are provided, so the description must fully disclose behavior. It only says 'upload' without indicating whether it overwrites existing files, requires authentication, is destructive, or what the response looks like, leaving significant gaps for an AI agent.

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 that conveys the core function with no wasted words, fitting the 'front-loaded' ideal.

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?

With 2 simple string parameters, no output schema, and no annotations, the description is adequate but lacks details about upload behavior (e.g., overwrite, error handling, file size limits) that would help an agent use the tool reliably.

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 100%, with both parameters already described (cache_path: 'Relative cache path', remote_path: 'Remote path including filename, e.g. /docs/report.pdf'). The description adds no extra meaning beyond this, so baseline score of 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?

The description clearly states the action (upload) and the specific source (local MCP cache) and destination (Cloudreve), distinguishing it from sibling tools like 'upload_file' (likely local filesystem) and 'cloudreve_download_to_cache' (inverse operation).

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 implies usage when a file is already in the MCP cache and needs to be uploaded to Cloudreve, but it does not explicitly state when to use this tool versus alternatives like 'upload_file', nor does it mention prerequisites or exclusions.

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