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

No annotations are supplied, so the description carries the full behavioral burden. It discloses one real constraint (referenced pipelines must be owned by the caller) and a doc reference, but says nothing about validation behavior, what happens with an invalid graph, whether creation is atomic, or what a successful call returns (e.g., a workflow id).

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?

Three short sentences, front-loaded with the action and then the one structural detail that matters. It is dense rather than padded, though the parenthetical doc pointer mid-sentence slightly interrupts flow.

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 7-parameter creation tool with no annotations and no output schema, the description is thin: it covers the graph shape and ownership rule but omits scheduling parameters and return behavior. The doc pointer partially compensates, but an agent could still call this incorrectly without reading external docs.

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 description only characterizes graph ({nodes, edges}) and the pipeline/for_each node types. Six of seven parameters — name, run_at, enabled, cron_expr, task_variables, inbound_trigger_only — get no meaning from either the schema or the description, leaving an agent to guess at cron format and variable scoping.

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?

Opens with a specific verb+resource ('Create a workflow'), which is unambiguous and distinct from siblings like workflow_update or workflow_run. It does not explicitly contrast itself with workflow_validate or workflow_update, so it stops short of 5.

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 statement of when to use this versus workflow_validate (validate first?) or workflow_update (edit an existing graph). The only guidance is an ownership precondition on referenced pipelines and a pointer to webarm://docs/workflows, which is a prerequisite rather than a when-to-use rule.

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