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

With no annotations at all, the description carries the full burden and does a fair amount: it discloses the row granularity, that versionId is the latest saved version and the one to build against, that liveVersionId is non-null only when the live version differs, and that a LIVE version cannot be edited. It leaves out the read-only guarantee, pagination/result-size behavior, and any permissions needed.

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 the action first, then the row shape, with field caveats in tight parentheticals. Nothing is padding.

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?

There is no output schema, so the description rightly enumerates the returned columns and their version semantics, which is the most valuable thing it could say. It is not fully complete: no ordering, pagination, or handling of flows without a live version beyond the liveVersionId hint.

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?

Only one parameter (workspaceId) and schema description coverage is 0%, so the description would need to compensate. "The workspace's flows" implies the scoping role of workspaceId and nothing else; no format, no guidance on where to obtain an ID.

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?

"List the workspace's flows, one row per flow" gives a specific verb plus resource, and the enumerated row fields make clear this is a summary listing rather than a full JSON dump (get_flow_json) or an instance listing (list_flow_instances). It stops short of naming any sibling explicitly, so it lands at clear-but-undifferentiated.

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?

Usage is only implied: you list flows for a given workspace, and the parenthetical "build against it" hints the versionId is what to use downstream. There is no statement of when to prefer this over get_flow_json / get_flow_summary, and no prerequisites or exclusions.

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