Behavior3/5

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

Without annotations, the description must convey behavioral traits. It mentions locking, complete replacement, and optional activation, which adds some transparency. However, it omits authorization requirements, rollback behavior, or performance implications.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short but contains redundancy: 'Operation: Update, Create. Subject: DataElement. Will be useful for updating or creating data element.' could be condensed. The remaining sentences are efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 17 parameters and no output schema or annotations, the description lacks completeness. It does not explain return values, error handling, prerequisites, or what happens on partial updates. It is insufficient for a complex tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema covers 100% of parameters with descriptions. The description adds that updates are a 'complete replacement', which provides extra context. Baseline 3 is appropriate as the schema already does heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool updates an existing ABAP data element. However, it also mentions 'updating or creating', which conflicts with the sibling CreateDataElement tool. The main purpose is clear but slightly muddled.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description lists steps (lock, update, unlock, activate) but does not provide explicit guidance on when to use this tool versus CreateDataElement or other alternatives. No when-not-to-use information is given.

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