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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is fully covered by structured data. The description adds genuine context beyond that: results are scoped to the workspace and cover both active and archived sequences. It says nothing about result volume, pagination, or ordering, which are the remaining behavioral unknowns for a list operation.

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?

One well-formed sentence with the scope constraint front-loaded and no filler. Slightly redundant phrasing ('saved message sequences' restating the title's 'saved sequences'), but nothing an agent must wade through.

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 zero-required-parameter read tool whose annotations cover safety, the description supplies the essential scope and filter semantics. With no output schema, it could say more about what each listed item contains, but that is a minor gap for a simple enumeration 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?

Schema description coverage is 0% and the single parameter is a nested object, so the description carries real weight here. It does map to both nested fields — 'active or archived' corresponds to status and 'filtered by name' to q — but omits the default of 'active' and the 80-character cap on q, which matters given the zero coverage.

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 and resource ('Lists ... saved message sequences') plus scope (workspace-level, active or archived, optional name filter), which separates it from the singular read tool getSequenceTemplate. It does not name any sibling explicitly, but 'list' vs 'get'/'create' makes the intent legible.

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?

There is no when-to-use or when-not-to-use guidance and no mention of alternatives such as getSequenceTemplate for a single template, or archiveSequenceTemplate for state changes. The only usage signal is the passive mention of active vs archived and the name filter, which is implied context rather than guidance.

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