manage_sequences

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions actions (list, add_subscriber, list_subscribers) but lacks critical details: it doesn't specify required permissions, rate limits, side effects (e.g., whether add_subscriber sends emails), or response formats. For a tool with multiple actions and no annotation coverage, this is a significant gap in transparency.

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 and well-structured in a single sentence, listing actions clearly without unnecessary words. It front-loads the purpose and actions efficiently. However, it could be slightly improved by organizing actions into a bulleted list or separating them more distinctly, but this is minor.

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 tool's complexity (managing sequences with multiple actions), lack of annotations, and no output schema, the description is incomplete. It doesn't explain return values, error conditions, or behavioral nuances like how 'add_subscriber' interacts with sequences. For a multi-action tool without structured support, more detail is needed to guide the agent effectively.

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?

The input schema has 0 parameters with 100% coverage, so there are no parameters to document. The description doesn't need to add parameter semantics, and it appropriately avoids discussing nonexistent parameters. A baseline score of 4 is applied since the schema fully handles the parameter documentation burden.

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: managing Kit email sequences with three specific actions (list, add_subscriber, list_subscribers). It specifies the resource (email sequences) and verbs (manage, list, enroll, list subscribers), making the purpose unambiguous. However, it doesn't explicitly differentiate this from sibling tools like manage_broadcasts or manage_subscribers, which prevents a perfect score.

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 provides no guidance on when to use this tool versus alternatives. It lists actions but doesn't indicate scenarios for choosing this over sibling tools like manage_subscribers or manage_broadcasts, nor does it mention prerequisites or exclusions. This leaves the agent without contextual usage direction.

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