Generate knowledge base index

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

The description discloses that the tool writes to docs/kb/index.md and requires a license feature, which is behavioral information beyond the empty annotations. However, it does not mention idempotency, potential side effects, or behavior when the file is missing, leaving some transparency gaps.

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 a single, front-loaded sentence that conveys the action, target, source, and prerequisite without unnecessary words. Every element 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 parameterless tool, the description adequately covers the core purpose, data source, and license requirement. It does not mention edge cases like missing index files or when to run it, but the simplicity of the tool makes these non-critical gaps.

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 tool has zero parameters, so the schema is fully covered and the description needs no parameter explanation. The baseline of 4 is appropriate as there is nothing to add.

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 specific action 'regenerate', the target resource 'docs/kb/index.md', and the data source 'saved cases'. It is distinct from sibling tools that read, search, or save knowledge base cases, making the purpose unmistakable.

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 implies the tool is for rebuilding the index from saved cases but does not explicitly state when to use it versus alternatives like hana_search_knowledge_base or hana_read_kb_case. No exclusion or alternative references are provided, leaving the usage context somewhat implied.

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