get_abap_subjects

Retrieve the complete ABAP Subject Directory with all topics and documentation page references, alphabetically organized. Use it to search and explore specific ABAP subjects.

Instructions

Get the complete ABAP Subject Directory with all entries. Returns all subjects/topics with their documentation page references, organized alphabetically. Use this to let the LLM search for specific ABAP subjects.

A4.4/5.0
Behavior4/5

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

With no annotations, the description carries the full burden. It discloses that the tool returns all entries (no filtering), includes page references, and is alphabetically organized, implying a read-only directory operation. This is meaningful behavioral context beyond just 'get subjects.'

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

Conciseness5/5

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

The description is two tight sentences: the first states what the tool does, the second states when to use it. No redundancy or irrelevant details, making it highly efficient.

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

Completeness4/5

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

Given there is no output schema, the description appropriately summarizes the return content (subjects/topics with page references) and organization (alphabetical). It doesn't detail exact data structures, but for a zero-parameter directory tool, this is reasonably complete.

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

Parameters4/5

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

The tool has zero parameters, so the schema is trivially complete. The baseline for 0 parameters is 4, and the description adds no parameter-specific details because none are needed.

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

Purpose5/5

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

The description clearly states the tool gets the complete ABAP Subject Directory, and specifies it returns all subjects/topics with documentation page references, organized alphabetically. It is well-scoped and distinguishes from siblings like search_abap_keyword by emphasizing 'complete' and 'all entries.'

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

Usage Guidelines4/5

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

The description explicitly says 'Use this to let the LLM search for specific ABAP subjects,' providing a clear use case. However, it does not mention alternatives or exclusions, so it lacks the 'when-not-to-use' guidance that would earn a 5.

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