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

The annotations already establish that this is a safe read-only, non-destructive operation. The description adds meaningful behavioral context about the returned data shape: it is bounded, linear, with at most one branch point and no nesting, rejoining, or parallel paths. It does not cover ordering or pagination, so it falls short of the richest disclosure.

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?

Two sentences, neither padded, with the returned resource stated first and the bounded shape explained immediately after. The second sentence is dense but every clause carries useful structural information.

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 list tool with one optional parameter, read-only annotations, and no output schema, the description supplies the key missing context: the bounded shape of sequence results. It still does not describe ordering, pagination, or whether an omitted project means the connection default, but it is largely complete for correct 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?

There is one optional project parameter, and schema coverage is 100%, so the schema already explains that it scopes the call to a project from list_projects. The description mentions 'this project' but does not add further semantics beyond the schema. This matches the baseline of 3 when the schema does the heavy lifting.

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 identifies the resource as sequences in the current project and adds that steps and branch structure are included. It is specific enough to distinguish this from sequence mutation tools like activate_sequence or update_sequence, though it does not explicitly state a list verb or name an alternative.

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 does not mention list_sequence_enrollments, update_sequence, draft_sequence, or any condition for choosing this read/list operation over them.

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