Attach File to Item

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

With no annotations the description carries the full burden and does reasonably well: it discloses the two-step mechanic (multipart upload to the file API, then attach), the 100MB size cap, and the returned fields. It omits auth/permission requirements and failure behavior, keeping it 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?

Front-loaded with the action, then the mechanics, then the return shape and limit. Mostly every sentence earns its place, though the 'Provide the absolute file path... and the target item ID' sentence largely repeats what the schema already declares.

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?

There is no output schema, so the description usefully names the return payload (file ID, name, size, download link), and the size cap plus two-step flow cover the essentials for a low-complexity 3-parameter tool. Permission/auth expectations are the only notable omission.

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%, so the schema already documents all three parameters including the filename override default. The description restates the absolute-path and item-ID requirements without adding format or constraint detail beyond the schema, so the baseline 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?

States a specific verb+resource pair ('Uploads a local file and attaches it to a Podio item in one operation'), and no sibling tool competes for this action, so the agent can select it unambiguously.

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 gives invocation context ('Provide the absolute file path on disk and the target item ID') but never states when to prefer this over alternatives or any prerequisites/exclusions, e.g. whether the item must already exist. Usage is implied rather than guided.

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