ck_list_sequences

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

Annotations already declare readOnly, idempotent, non-destructive, and open-world, so the safety profile is covered externally. The description adds only that the listing is unfiltered ('all'); it says nothing about result caps, pagination, ordering, or what an empty account returns, so it adds limited behavioral context beyond the structured hints.

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 zero filler; the resource and scope appear immediately. It is efficiently sized, but the terseness comes at the cost of the missing parameter and behavior detail rather than being a deliberate compact style.

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?

For a simple read-only listing tool with annotation coverage this is close to adequate, and no output schema means return values need not be described. However, the required api_key is unexplained in both schema and description, and nothing indicates whether results are paginated or complete, leaving real gaps for a one-parameter tool.

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?

There is one parameter (api_key) with 0% schema description coverage, so the description carries the full burden and fails to explain what the key is, that it is required, or how it is obtained. A single undocumented credential parameter with no compensating text in the description leaves the agent relying on inference.

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?

States a specific verb+resource ('List all email sequences') scoped to a ConvertKit account, so the agent knows exactly what it returns conceptually. It does not distinguish itself from the ConvertKit siblings (ck_list_subscribers, ck_list_forms, ck_list_tags), though the distinct resource noun does most of that work.

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?

'List all' implies the intended use is full enumeration with no filtering, which is a usable but only implicit guideline. There is no statement of when to prefer this over other ConvertKit listing tools, no prerequisites (API credentials, account scope), and no mention of pagination limits.

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