create_checklist_jwt

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

With no annotations, the description carries the full burden and does substantial work: it discloses the JWT authentication mechanism, the browser/SAML side effect when no token is cached, and the JSON return format. It doesn't cover permissions or failure handling in detail, but it makes the main non-obvious behavior visible.

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 organized into purpose, auth warning, args, and return sections, making it scannable. The auth rationale is stated twice in slightly different forms, but no sentence is wasted for a tool with 7 parameters and no schema documentation.

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?

The definition covers everything required to invoke the tool: required and optional parameters, auth prerequisite, browser side effect, and return type. It would be more complete with an explicit pointer to create_checklist_from_template_jwt when a template-only creation is intended, and it doesn't mark name as required in the prose, but the schema covers requiredness.

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 0%, so the description is the only prose source for parameter meaning. It enumerates all seven parameters and adds useful semantics: due_date format, optional template ID, assignee ID meaning, and restricted flag. Some descriptions are tautological ('name: Checklist name') and organization_id is the only parameter marked required, but the schema already pins required fields.

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 opens with a specific verb ('Create') and resource ('new checklist'), and explains the JWT authentication requirement so the agent knows which auth path applies. However, it doesn't distinguish itself from the sibling create_checklist_from_template_jwt, which could also create a checklist with a template ID, so sibling differentiation is incomplete.

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 text explicitly says JWT is REQUIRED for checklist creation because IT Glue's API key auth doesn't support it, giving clear when-to-use context. It also warns that a missing cached token will open a browser window for SAML, which sets user expectations. It doesn't name alternatives or say when not to use the template-based sibling, so it's just below a top score.

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