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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds useful behavioral context beyond the annotations: the server is stateless and serves only built-in shipped templates, which prevents an agent from expecting user-saved workflows. It does not describe pagination or a full return shape, but that is a minor gap for a listing tool.

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 three sentences, front-loads the core resource and returned fields, then adds the id behavior and the stateless limitation. Every sentence earns its place, and there is no filler or repetition.

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 low-complexity, one-parameter, read-only listing tool, the description is complete enough. It covers the listing content, the id-filtered graph result, the run_workflow handoff, and the stateless scope limitation; no output schema exists, but the description sufficiently characterizes what comes back.

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 100%, so the schema already documents that id is optional and that omitting it returns the whole listing. The description adds meaning by explaining what passing an id yields — that template's graph, ready to hand to run_workflow — which goes beyond the terse schema note.

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 names a specific resource ('built-in starter workflows') and states exactly what is returned: id, name, description, and chained tools. It also distinguishes this listing from user-saved workflows and names the downstream consumer, run_workflow, so an agent can tell what this tool is for without opening the schema.

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?

It clearly explains the two call modes: omit id for the whole listing, or pass id to get that template's graph ready for run_workflow. It also gives a real exclusion — this server is stateless, so only shipped templates are available, not personal saved ones. It does not, however, compare against sibling workflow tools such as validate_workflow or plan_next_tools.

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