get_indices_bars_daily

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

Annotations already declare readOnlyHint, destructiveHint, idempotentHint, and openWorldHint, covering safety. The description adds return type details (OHLC and volume) but no additional behavioral traits beyond what is implied by the schema.

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 concise, front-loaded with the purpose, and uses a clear structure with supported plans and an Args block. Every sentence adds value without unnecessary words.

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 existence of an output schema, the description adequately covers what the tool does and its parameters. It could mention that it returns multiple rows for a date range, but overall it is mostly complete for a simple retrieval tool.

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?

With 0% schema description coverage, the description compensates by providing examples for 'code' (e.g., 0000 = TOPIX) and date formats (YYYYMMDD or YYYY-MM-DD), and explains 'date_from' and 'date_to' as range boundaries. This adds meaningful context beyond the bare schema.

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 verb 'retrieve' and resource 'daily index bars (OHLC)' and lists specific indices like TOPIX and Nikkei 225. However, it does not explicitly differentiate from the sibling 'get_indices_bars_daily_topix', which appears to be a subset.

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 usage hints such as date formats and example index codes, and mentions supported plans, but lacks guidance on when to use this tool versus alternatives like 'get_indices_bars_daily_topix' or when not to use it.

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