attach_url

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

The description discloses that the URL must be publicly accessible, a key behavioral trait. However, with no annotations, it lacks details on failure modes, authentication, or rate limits. It meets the minimum but doesn't fully cover behavioral aspects.

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 two concise sentences with no wasted words. It is front-loaded with the core action and includes an important constraint second. Every sentence is necessary.

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 no annotations and no output schema, the description covers the essential purpose and constraint but does not mention return values or error handling. For a simple tool, it is minimally complete but lacks some 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 coverage is 100%, so baseline is 3. The description adds value by specifying that the URL must be publicly accessible, which is not in the parameter description. This extra constraint enhances semantics beyond the schema.

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 action: attaching a file from a URL to a task. The verb 'attach' and resource 'file from URL to a task' are specific, and the constraint 'URL must be publicly accessible' adds clarity. It distinguishes from sibling tools like add_task_comment.

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 usage for attaching publicly accessible files but does not provide explicit guidance on when to use this tool versus alternatives, nor does it mention when not to use it. No exclusions or alternatives are mentioned.

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