solnk_create_media_upload

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

With no annotations, the description carries the full burden. It explains that the tool returns a presigned upload_url and media_id, outlines the subsequent steps (PUT with Content-Type header), notes the URL expiration (15 min), and mentions file limits. It does not cover error cases or authorization, but provides substantial behavioral detail.

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 concise (single paragraph), front-loaded with the main action, and every sentence adds value. It efficiently conveys steps, alternatives, and limits without unnecessary words.

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 multi-step upload process and no output schema, the description effectively explains the entire workflow and ties to sibling tools. It lacks description of the output format or error handling, but covers essential contextual information for an agent to use the tool correctly.

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 67%, so the baseline is 3. The description does not add parameter-level information beyond the schema's own descriptions (e.g., filename, size_bytes have schema descriptions). It contextualizes parameters in the workflow but does not elaborate on each parameter's semantics. Adequate but not enhanced.

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: uploading a local image/video file via a 3-step process. It distinguishes itself from the sibling solnk_create_media_from_url by specifying local file vs public URL. Limits (500 MB, allowed types) are provided.

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 states when to use this tool (local file) and when to use the alternative (solnk_create_media_from_url for public URLs). It outlines the required steps after calling this tool. It does not give explicit 'do not use' conditions but provides sufficient guidance.

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