get_or_create_rag_indexes

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

Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false, and destructiveHint=false, so the safety profile is partly covered. The description adds only "In Batch," which is also implied by the schema's 1–100 item constraint, and says nothing about side effects, non-idempotent behavior, or what gets created or modified. It does not contradict the annotations, but it adds essentially no behavioral context beyond them.

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 four words and front-loaded, but it is under-specified rather than effectively concise. It omits the core get-or-create distinction needed to select and invoke the tool correctly. Brevity here leaves the agent with unresolved ambiguity.

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?

With no output schema, the description should compensate by explaining get-or-create behavior, batch semantics, and likely return shape. Instead it omits all of that, despite the tool's non-read-only, non-idempotent, open-world annotations. The schema covers the parameter list, but the overall definition remains incomplete for correct invocation.

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%, and the single parameter items is already documented as "List of requested RAG indexes. Minimum 1, maximum 100 items." The description adds no parameter syntax, item shape, or usage detail beyond what the schema provides. This aligns with the baseline 3 when the schema already carries parameter meaning.

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 phrase gives a verb and resource ("Compute Rag Indexes") plus batch scope, so it is not a bare tautology. However, it is vague about the actual get-or-create semantics of the tool and does not distinguish it from siblings like get_rag_indexes, get_rag_index_overview, rag_index_status, or delete_rag_index. An agent cannot tell from this description whether it fetches existing indexes, creates new ones, or does both.

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 guidance about when to use this tool instead of get_rag_indexes, get_rag_index_overview, rag_index_status, delete_rag_index, or query_agent_knowledge_base_rag_route. No prerequisites, exclusions, or contextual triggers are stated. The description gives only an action label, leaving the agent to infer usage.

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