UpdateServiceBinding

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

No annotations are provided, so the description must fully disclose behavioral traits. While it indicates mutation (updating state), it omits details on permissions, side effects, reversibility, or response characteristics. The mention of 'Create' further muddles the expected behavior.

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 short (three sentences), but the first sentence is redundant ('Operation: Update, Create. Subject: ServiceBinding.'). It could be more concise and front-loaded with the core 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?

Given the tool's complexity (6 parameters, no output schema, many siblings), the description is insufficient. It does not explain relationship to CreateServiceBinding, return values, or edge cases, leaving significant gaps for an agent.

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?

The input schema covers 83% of parameters with descriptions, so the schema already provides good meaning. The description does not add any additional parameter-specific guidance, but the baseline effort is adequate.

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 states 'Update publication state of an existing ABAP service binding,' which clearly identifies the primary action and resource. However, it also mentions 'Operation: Update, Create' and 'useful for updating or creating,' creating ambiguity about whether it can create new bindings. This is misleading given the tool name and the existence of a sibling CreateServiceBinding tool.

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 no guidance on when to use this tool versus alternatives like CreateServiceBinding or other Update tools. It lacks any contextual cues or exclusions, leaving the agent without clear decision-making information.

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