UpdateBehaviorDefinition

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

Explicitly states the process: Locks, updates, unlocks, and optionally activates. This reveals the sequential behavior and that activation is optional. No contradictions with annotations (none provided).

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?

Description is relatively short but includes a redundant first sentence ('Operation: Update, Create. Subject: BehaviorDefinition.') that adds no value. The remaining sentences are clear and structured.

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?

Given the complexity (5 params, no output schema), the description covers the main behavior (lock, update, unlock, activate) and explains lock_handle handling. However, it lacks information on failure scenarios, return value, or when activation is needed vs. using ActivateBehaviorDefinition separately.

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 parameter descriptions, but the description adds extra semantics: explains that lock_handle can be omitted (internal lock) and warns against using it in stateful flows. This provides useful context 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?

Clearly states it updates the source code of an existing ABAP Behavior Definition (BDEF) with locking/unlocking and optional activation. However, the first line mentions 'Update, Create' which is slightly misleading given the tool name and sibling CreateBehaviorDefinition, but the core action is clear.

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?

No explicit guidance on when to use this tool versus CreateBehaviorDefinition or ActivateBehaviorDefinition. The phrase 'Will be useful for updating or creating' is vague and doesn't help differentiate from siblings.

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