upload_image_from_file

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

No annotations are provided, so the description must carry the full burden. It only states the basic upload action and destination, without disclosing behavioral traits like error handling, file size limits, permissions, or what happens on success. This is insufficient for a file upload tool.

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 extremely concise with two sentences, no redundancy, and front-loads the action and destination. Every word adds value relative to the tool's simplicity.

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?

Given the tool has three parameters, no output schema, and no annotations, the description is too brief. It omits crucial context such as return values, error conditions, file format or size constraints, and any prerequisites for local file access. This incompleteness could hinder correct invocation by an AI agent.

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 input schema has 100% coverage with descriptions for all parameters. The description adds no additional meaning beyond 'local image file' and the intended audience, so it meets the baseline but does not improve understanding.

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 a local image file') and the destination ('Basis (Pinata/IPFS)'), and distinguishes from the sibling tool 'upload_image_from_url' by emphasizing 'local file access'.

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 explicitly targets 'agents/Claude Code with local file access', implying the tool is for local files rather than URLs, but it does not explicitly state when not to use it or provide alternatives beyond the sibling name.

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