merit_create_vendor_group

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does disclose the mutating nature via 'Create' and POST, and hints that the client supplies the GUID. However, it does not cover response format, idempotency when re-sending the same GUID, or error behavior — meaningful gaps for an operation with zero annotation support.

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 sentence front-loads the action and endpoint, followed by a compact summary of required fields with constraints. Every word earns its place and there is no filler.

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 simple 3-parameter create tool with no output schema and no nested objects, the description covers the purpose, endpoint, and required fields completely. Minor gaps around response/error behavior remain, but nothing an agent needs to invoke the tool successfully is missing.

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 all three parameters. The description restates constraints (GUID, max 64, max 20) that are already present in the schema property descriptions, adding no genuinely new semantic information. Baseline 3 applies.

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 the specific verb ('Create'), the resource ('Merit Aktiva vendor group'), and the exact endpoint (POST /api/v2/sendvendorgroup). This clearly differentiates it from sibling create tools like merit_create_customer_group and merit_create_vendor without needing to open their schemas.

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?

The purpose statement gives clear context: an agent can tell this is the tool for creating vendor groups in Merit Aktiva. However, it names no sibling alternatives (e.g., merit_list_vendor_groups for listing, merit_create_customer_group for customer groups) or when-not-to-use conditions, so it stops short of explicit routing guidance.

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