ActivateStructure

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

No annotations are provided, so the description carries full burden for behavioral disclosure. It only states the activation action and condition (if inactive), but does not mention side effects, prerequisites (e.g., session requirements), idempotency, error behavior, or response format. This is insufficient for a mutation tool.

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 consists of two concise sentences with no redundancy. Every word adds value: 'Activate an ABAP structure. Use after CreateStructure or UpdateStructure if the object remains inactive.' Front-loaded with the primary action.

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 description lacks details on return values (no output schema), error handling, and when session parameters are needed. Given the complexity (3 parameters, nested objects) and no output schema, the description is minimally adequate but leaves gaps.

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%, with each parameter adequately described (e.g., structure_name, session_id, session_state). The tool description adds no additional meaning beyond the schema, so 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 clearly identifies the tool as activating an ABAP structure, with a specific verb 'Activate' and resource 'structure'. It distinguishes from sibling Activate* tools by naming the object type explicitly and providing context (use after CreateStructure or UpdateStructure if inactive).

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 explicitly states the usage scenario: after CreateStructure or UpdateStructure when the object remains inactive. While it does not list exclusions or alternatives, the context is clear enough for agent decision-making among siblings.

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