get_abap_index

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states that the tool returns all entries and organizes them alphabetically, which adds context, but it does not mention potential response size, pagination, or explicitly confirm that this is a read-only operation. The description is honest but not richly detailed.

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 two sentences, front-loaded with the core action and result. The second sentence adds a practical usage hint without unnecessary elaboration. Every phrase earns its place.

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?

For a simple no-parameter getter, the description adequately covers what the tool does and what it returns. The main gap is the lack of explicit differentiation from the sibling search tool, which could mislead an agent in tool selection, but the description is otherwise complete for its simplicity.

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 has zero parameters, so there is no parameter meaning to convey. The description appropriately focuses on the return value instead. Given the 0-parameter baseline of 4, this is a solid score.

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 states the action: 'Get the complete ABAP Keyword Index with all entries' and specifies the return content: 'all keywords/terms with their documentation page references, organized alphabetically.' This specific verb+resource combination distinguishes it from sibling search_abap_keyword, which likely performs a targeted search.

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 an implied use case: 'Use this to let the LLM search for specific ABAP keywords,' but it does not explicitly contrast this with the alternative search_abap_keyword tool or state when to prefer one over the other. It lacks clear exclusions or alternative guidance.

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