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

Annotations already declare readOnly=false, destructive=false and idempotent=false, so the safety profile is largely covered. The description adds two things the annotations do not: a staff-only access restriction and the fact that the result is a copied workflow in this workspace rather than a reference to the template. It does not warn that repeat calls will produce separate copies, which matters given idempotentHint=false.

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?

Four short sentences, front-loaded with the access restriction and the core action, then the editing chain, then the parameter choice. No sentence is redundant and none repeats schema or annotation content.

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 and the description never says what comes back, yet the recommended next step is get_step, which needs an identifier the agent cannot know without it. Coverage of the mutation and the editing lifecycle is otherwise strong for a two-parameter 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%, so the description must carry the full burden, and it does identify both parameters' sources and the choice between them. It stops short of saying what template_id points at (a library template id) or that both are optional but one is needed in practice, leaving the required=0 schema slightly ambiguous.

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 states a specific verb and resource ('Copy a draft or Ready for review library template into this workspace as a workflow') and immediately scopes who may do it ('Hive staff only'). It is clearly distinguishable from library_save_draft, library_build_idea and build, which appear nowhere in the verb phrase.

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 gives an explicit post-call sequence (get_step, edit_step, add_step, remove_step, then library_save_draft) and resolves the parameter fork: template_id for a library template, idea_id 'for the draft its build made'. What is missing is any statement of when not to use it, e.g. starting from a blank workflow via build instead of a template.

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