Uploadkit

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

With no annotations provided, the description carries the full burden and does an excellent job disclosing behavioral traits: it states the tool is 'read-only, idempotent, never modifies anything' and specifies the return format ('plain-text shell command as a single string'). It could improve by mentioning error handling or rate limits, but covers core safety and output behavior well.

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 efficiently structured with three focused sentences: purpose, usage guidelines, and behavioral traits. Every sentence adds value without redundancy, and key information is front-loaded. It's appropriately sized for the tool's complexity.

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 tool with no annotations and no output schema, the description provides strong coverage of purpose, usage, and behavioral transparency. It explains what the tool returns and its safety profile. The main gap is lack of explicit error case handling, but overall it's quite complete for this context.

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 schema already documents both parameters thoroughly. The description adds some context about default package selection and project scoping, but doesn't provide significant additional semantics beyond what's in the schema descriptions. This meets the baseline for high schema coverage.

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 tool's purpose with specific verb ('Return') and resource ('exact shell command to install UploadKit packages'), distinguishing it from siblings like get_component or get_doc which return different resources. It explicitly mentions what it returns and for what purpose, making its function unambiguous.

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 explicit guidance on when to use this tool ('before asking the user to add dependencies') and how to choose parameters ('match their package manager... detect from lockfiles... otherwise ask or default to pnpm'). It also implicitly distinguishes from siblings by focusing on installation commands rather than documentation or components.

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