SAP Chat Derive Room

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

The description claims the tool derives an ID, suggesting a read-only operation, but annotations indicate readOnlyHint=false, creating a contradiction. No additional behavioral traits are disclosed beyond the DM reservation note.

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 concise with two sentences: first stating purpose, second adding status and reservations. No unnecessary words, and information is front-loaded.

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?

Despite having an output schema and annotations, the description leaves gaps: it contradicts annotations, lacks usage guidelines, and does not explain side effects or prerequisites. The DM reservation note helps but overall completeness is low.

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 coverage is 100%, so parameter descriptions already exist. The tool description adds marginal value by hinting at roomKind behavior (DM reserved), but does not enhance understanding of other parameters beyond the schema.

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 explicitly states it derives a deterministic SAP chat room/session ID, distinguishing it from sibling chat tools like sending messages or starting rooms. The mention of 'Group and public room IDs are active' further clarifies scope.

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 description provides context about active room kinds (group and public) and notes DM derivation is reserved, implying when to use it. However, it lacks explicit guidance on when not to use it or alternatives like sap_chat_start_room.

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