Create Functionality

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=true, so the safety profile is covered. The description adds no further behavioral context — it doesn't mention side effects, whether duplicate names collide (relevant since idempotentHint is false), or any auth/permission requirements for a mutation tool that touches many linked resources.

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 short sentence, front-loaded with the verb, so there is no bloat. However, the trailing phrase "from provided data" is pure filler and the brevity comes at the cost of substance rather than being earned concision.

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?

The tool takes a deeply nested object with many linked-entity fields, so the description should clarify what the create operation requires and what gets set. An output schema exists so return values needn't be explained, and annotations cover safety, but the description still leaves the agent without enough to know what a valid creation looks like.

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 reported at 0% for the top-level parameter, and the description only says "from provided data", which gives no meaning about the required type/attributes envelope. Nested fields do carry their own schema descriptions (including the deprecated slug note), which mitigates somewhat, but the description itself contributes nothing about which attributes are required.

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?

"Creates a new functionality" names a verb and a resource, so the basic action is identifiable, but "functionality" is a domain-specific entity that is never explained and "from provided data" adds nothing. It also does not distinguish itself from the sibling update_functionality or explain how a functionality differs from a service or catalog entity.

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 on when to use this versus update_functionality, or on prerequisites such as required permissions or whether related entities (services, environments, owner teams) must already exist. Only the verb "creates" implies the usage context.

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