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

No annotations are provided, so the description carries the full burden. It only says 'Create or update' and the matching key, but does not disclose behavioral details such as whether updates are partial or full, what happens if no match exists, idempotency, permissions, or error responses.

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?

A single front-loaded sentence with the action and key matching logic; every word earns its place.

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?

As a mutation tool with no annotations and no output schema, the description is too sparse. It lacks information about creation vs update semantics, return values, error behavior, or permission requirements, which an agent would need for reliable invocation.

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 only 25%, so the description needs to compensate. It clarifies that title and company_name serve as the match key, which adds meaning to those required parameters. However, it provides no guidance for the other six parameters (icon, message, image_url, content_link, etc.), leaving the agent to rely on names alone.

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 operation (create or update) and the resource (Magic Dash Item) plus the matching criteria (title + company_name). This distinguishes it from sibling tools like list_magic_dash, delete_magic_dash, and update_magic_dash_positions.

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 the use case (creating/updating a magic dash item identified by title and company_name) but does not explicitly state when to use this versus alternatives, nor does it mention exclusions. Sibling tool names are visible but no guidance is given.

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