list_engine_ini_sections

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive), but the description adds real behavioral context: it reads the merged in-memory GConfig and returns found=false when GConfig does not know the INI. That not-found semantics is useful disclosure beyond the annotations.

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?

Purpose is front-loaded and the tool is described in a compact two-sentence form. However, the trailing 'Returns:' line largely repeats the field list (count, sections, found, file_path) already given in the first sentence, which is mild redundancy.

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?

With no output schema, the description usefully enumerates the return shape and the found=false edge case, and annotations carry the safety profile. It is close to complete for a simple read tool, with only minor overlap instead of additional depth.

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%, so both config_file and the intentionally-ignored include_base are fully documented in the schema. The description adds little param-level meaning (it echoes config_file and file_path), so baseline 3 applies.

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?

States a specific verb (list) and resource (section names of one INI in the merged in-memory GConfig), and explicitly ties its read semantics to a sibling (get_engine_ini_value). An agent can distinguish it from generic INI/value readers without opening the schema.

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 reference to get_engine_ini_value clarifies the reading model and implies a use case (inspect which sections exist for a given config), but it never states when to choose this over alternatives or what conditions favor it. Usage is implied rather than explicit.

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