bw_create_composite_provider

Create a CompositeProvider (HCPR) as a Union or Join view, optionally adding source providers, or copy an existing structure. Join nodes require inputs; activate the inactive result afterward.

Instructions

Create a CompositeProvider (HCPR). Without copy_from it creates a view node of the given type with the listed source providers attached — entity only, so give them their mappings afterwards with bw_update_composite_provider action "update_mapping". A Union node may be created empty; a JOIN node must be created WITH its sources, since a join node without inputs makes the server dump. With copy_from the server copies view node, inputs and mappings from an existing CompositeProvider. The result is inactive — activate it with bw_activate (object type hcpr).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
labelYesDescription.
inputsNoSource InfoProviders to attach right away. Required in practice for a Join node.
packageNoDevelopment package (default "$TMP").
copy_fromNoCopy the structure of this existing CompositeProvider. view_type, inputs and stackable are then irrelevant — they come from the template.
info_areaYesInfoArea to create it in (e.g. "AREA_NAME").
stackableNoDefaults to false.
view_typeNoView node type. Defaults to "Join".
composite_provider_nameYesName for the new CompositeProvider (e.g. "HCPR_NAME").
Behavior5/5

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

With no annotations available, the description fully carries the behavioral transparency burden. It disclose materials hidden side effects: a JOIN node without inputs crashes the server/creates a server dump, copied objects inherit mappings, and the created object is inactive and must be activated separately. These are not inferable from the name or schema and are highly decision-relevant.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is dense and well-front-loaded, starting with the action, then covering the no-copy path, the special JOIN/Union behavior, the copy path, and the final activation step. Every sentence earns its keep and no line is filler or repeated schema content.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that there is no output schema and no annotations, the description explains everything needed to call this tool correctly and safely: the Join-with-inputs strict prohibition, copy_from templating behavior, required post-creation mapping step, and required activation step. The only remaining details come from the fully-documented schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Since schema_description_coverage is 100%, the baseline is 3. The description adds real semantic value on top by explaining that inputs are required in practice for JOIN, that copy_from overrides view_type/inputs/stackable, and that a fresh creation produces an entity-only node requiring a mapping update. It does not add depth on every parameter, but it covers the materially tricky ones.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The first sentence states the exact action and resource: 'Create a CompositeProvider (HCPR).' It then distinguishes fresh creation from copy-based creation and pairs the tool with the follow-up tools bw_update_composite_provider and bw_activate, clarifying the object lifecycle versus those siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description is explicit about when to use the copy_from path versus the fresh path, and about Union being allowed empty while JOIN must include inputs. It also directs the agent to the exact follow-up tools for mappings and activation, making the overall workflow unambiguous.

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